Cyber attacks of recent years have grown in number and size, making it crucial to alert the computing world at large of the need to protect data assets and network infrastructure. Large corporations, small businesses, and even private individuals are all subject to attack from criminal-minded hackers who are bent on profiting from illegal penetration into your computing system. Many of the most high-profile cyber attacks of recent years targeted large corporations, simply because of the potential for extracting more substantial sums of money from them in exchange for the safe return of business assets (ransomware). While attacks against small businesses (SMB’s) have not garnered the headlines nor the high visibility of major attacks against big corporations, that doesn’t mean they aren’t taking place. In fact, small businesses now are being hit much more frequently because hackers have realized that, all those small profits from SMB’s do add up to big money in total. Statistics show that over the past several years, more than half of small businesses have had network security breached in some way by hackers. This alarming development should clearly point out the need for small businesses to be on the alert, small business cyber security should be taken seriously.
Managing the Risk of Cyber Attacks Against Small Businesses
In addition to the cumulative appeal of profits from small business attacks, there is another reason why criminals have been turning their attention to SMB’s. With fewer resources allocated to cybersecurity, and less formalized training and education against the potential for cyber attacks, small businesses often present very inviting targets for the criminal-minded.
It’s also true that limited budgets make small businesses cyber security not as readily accessible. However, even with limited resources, there are at least a few necessary steps that all small businesses can take, which will reduce the likelihood of an attack, and at least provide some measure of security for valuable business assets.
For instance, at least one person in every small business can be designated to stay abreast of all known cyberattack threats, so that it’s at least possible to take preventive measures against specific threats and risks. This would typically be an I.T. person who’s also responsible for keeping system software updated with any security patches made available by vendors. Soon after the newest cyberattacks appear, software gurus are at work developing fixes to patch whatever weakness allowed the attack to take place, and these should be applied to your software system as soon as they are made available.
It’s also imperative to take regular backups of business-critical data so that in the event of an attack like ransomware, there is always a safe and current version of data to fall back on, without surrendering to the demands of a hacker.
Education and Training on Small Business Cyber Security
It’s fair to say that the biggest vulnerability for small business cyber security is the lack of employee education and training. This, of course, is not limited to SMB’s, because even corporate giants are frequently exposed to cyber threats by the weakest point in their networks, which is the actions of employees.
Hackers are naturally aware of this, and much of their time and effort is spent trying to dupe unsuspecting company employees into providing them with crucial information like passwords or account data which will allow them to carry out attacks against the company network. All this should make it clear that one of the top priority investments in small business cyber security is to properly educate and train employees about cyber threats, and how they’re carried out and resolved.
Every employee needs to be aware of the potential for cyber attacks and should treat anything suspicious with extreme caution. At the bare minimum, all employees should be educated about the necessity for safeguarding passwords, credentials, and account information. Such attacks can be carried out through email phishing scams, or possibly social media, where cyber attackers are known to be listening, and waiting to exploit unsuspecting employees to obtain vital security information in a seemingly harmless environment.
Hackers can also obtain business details information from employees via social engineering, wherein cyber attackers manipulate employees by pretending to be clients, banking institutions, or other characters of authority or importance. Some of these attacks are made through phone calls where a supposed colleague requests to know changes made to account information need to be reminded of specific passwords to gain access to system software. Hackers posing as managers from other departments have also exploited unwary employees with phone calls asking for similar information, which can then be used to breach the computing system and hijack valuable company data assets.
Some small businesses in the country have gotten the message, and have taken whatever steps they can to prevent cyberattacks, or at least reduce the potential for them. If awareness is the first big step toward improving your small business cyber security, educating employees about cyber attacks can be said to be an essential second step. Hackers these days are determined to victimize small businesses as well as corporate giants, and that means SMB owners and managers have to be just as committed to preventing those attacks.
A study recently conducted by RiskVision, a respected developer of Risk Management software, determined that more businesses today are concerned about company reputation than they are about potential breaches of security which might impact them. It has long been known that companies consider a brand name to be one of their most significant assets, even though it’s an intangible that has value to no one outside the company itself.
In this survey, damage to a brand name was considered to be potentially more damaging than security breaches, even though the two often go hand-in-hand today. Hackers who successfully penetrate into a company’s computing network often do inflict serious damage to the reputation of the business, and subsequently its brand name. It should, therefore, be kept in mind by all business owners that security breaches need to be taken seriously, to prevent damage to the company brand-name, as well as all the usual financial ramifications.
How a Security Breach Can Damage Your Brand Name
Typically, the first thing a customer considers when thinking about brand names, about products or services, is whether or not the product or service provides quality and value, and whether the cost is in line with the levels of quality and value delivered. However, any company which has suffered a known security breach often falls into an entirely different frame of evaluation.
Consumers will often think that any business which has allowed itself to be hacked by criminals is not worthy of their trust and patronage. After all, if their business practices were lax enough to permit the cyberattack in the first place, that may be a sign that other important aspects of the business are also conducted with inadequate attention to detail. This fact is borne out powerfully in a poll jointly conducted by CSO and OnePoll, which attempted to determine the connection between insufficient security and a company’s brand name, as perceived by consumers.
In the survey, a whopping 86% of customers declared that they were unlikely to patronize a company which had suffered a severe security breach, especially if the breach was related to customer information. This represents a definite shift in consumer thinking from the early days of cyber attacks when businesses were perceived as victims entitled to understanding and sympathy from the public. In the now-famous cyberattack against department store giant Target, sales for the entire quarter after their security breach dropped like a rock, falling almost 50% from the prior quarter.
Impact of Security Breaches on Small Businesses
Major security breaches perpetrated against small companies can have an enormous effect and can cause irreparable brand-name damage from which recovery is either very difficult or downright impossible. In 2016, a study was conducted by KPMG which determined that almost 90% of small businesses had suffered serious brand name damage in the immediate aftermath of a security breach.
In a white paper published by the National Cyber Security Alliance, figures were released which showed that as many as 60% of all small businesses completely collapse less than six months following a significant cybersecurity breach. Interestingly, both of the studies referenced above reported that less than one-quarter of all small businesses considered cybersecurity to be a top priority. The fact that there has historically been relatively little concern about cybersecurity breaches may account for the often devastating impact that attacks have had on those business entities.
Taking Steps to Secure Your Business
A cyber security plan doesn’t need to be especially elaborate, and it doesn’t need to be funded to the hilt, with every conceivable kind of virus detection software. There just needs to be a well thought out plan for cybersecurity, and a legitimate effort to enforce that strategy. There are some straightforward but very cost-effective measures which can be adopted to thwart the vast majority of cyber attacks.
Using strong passwords on all company computers is a good start, followed up by installing security software on company devices. It’s always best to keep hardware and software updated with the latest available security patches and to periodically back up business-critical data. The weakest point of any company’s network should not be overlooked, which means employees need to be educated about the risks of cyber attack.
The important thing to remember about any cybersecurity policy is just to implement as many of the simple steps listed above as possible and to do it immediately so that your system is not left vulnerable to penetration by cyber attackers. As some of the survey results mentioned above make clear, every kind of business from the corporate giant on down to the mom-and-pop retail outlet must take all steps possible to avoid the possibility of major security breaches. Failing to do this can cost you a lot more than money – it can cause irreparable harm to your company’s reputation.
If you haven’t heard about key reinstallation attacks yet, they’re the most recent form of Wi-Fi hacking. It’s also possible that you actually have heard about them under their media nickname, which is ‘Krack Attacks.’
Regardless of the nomenclature, key reinstallation attacks are attempts to exploit a flaw in the Wi-Fi encryption protocol which permits hackers to hijack all kinds of personal information, including photos, passwords, and account numbers. The first thing to know about key reinstallation attacks is that they’re not specifically targeting any particular hardware, but rather a weakness in the Wi-Fi protocol itself.
This means that all smartphones, mobile devices, routers, and desktop machines are subject to attack, and any or all of your personal data may abruptly come into the possession of someone with criminal intent. Today, we’re here to discuss what you should know about this new threat.
How Key Reinstallation Attacks Work
Researchers have uncovered a flaw in the WPA2 Wi-Fi protocol which allows hackers to replicate a user’s network entirely, and by falsely representing the Media Access Control (MAC) address, which is a device’s physical address, it can actually cause a switch in Wi-Fi channels.
When a bogus network is set up in this way, it can actually intercept signals from any remote device attempting to connect to the original system, causing such attempts to bypass the real network, and instead connect to the rogue.
The way WPA2 encryption is supposed to work, it would require a unique key for any encryption request, but the flaw uncovered in the WPA2 protocol does not always need that specific key, and instead, reuses a previous one. The problem is particularly acute with Linux and Android, because of the way they make use of the WPA2 protocol. In these operating systems, a unique encryption key is not demanded every time an encryption request is made, leaving the system vulnerable to hacking.
In layman’s terms, the Wi-Fi protocol can be exploited when hackers can find a vulnerable network and take advantage of the WPA2 weakness, ultimately directing users to the rogue network for data hijacking.
Researchers Proof of Concept
Previous minor flaws had already been uncovered in the WPA2 protocol, so researchers were already fearful that some even more significant problem might be lurking within the software. The key reinstallation flaw was discovered by those researchers, who then conducted proof of concept experiments to attack a theoretically vulnerable Wi-Fi system. On an Android system, the researchers were successful in intercepting and decrypting all the test victim’s data.
According to these penetration experts, the same kind of ‘success’ could not be achieved on a system setup with HTTPS secure socket layers but would wreak havoc on sites which have been poorly set up and missing HTTPS. While Linux and Android are most severely affected because of how they use WPA2, other operating systems like Windows, MacOS, and OpenBSD would also be compromised but to a lesser degree. How serious is the issue for Android? Experts recommend that owners of Android devices shut off Wi-Fi until known fixes have been applied to close up the weakness in the protocol.
What You Can Do to Avoid Krack Attacks
One of the best things you can do to avoid the possibility of a key reinstallation attack is to look for the ‘https’ at the beginning of any URL for websites which you visit. That ‘https’ is an indicator that the site uses secure protocols, and you would be safe in visiting. You can also simply avoid using Wi-Fi for the time being, while software gurus hurriedly develop a fix for the vulnerability. This may be inconvenient, especially when you’re away from home or the office and might need Wi-Fi, but it’s much safer than having your sensitive data fall into the hands of a criminal.
One of the interesting things about these attacks is that a hacker must be within the physical range of your machine before the attack can be carried out, and while that does serve to shield many users from harm, an actual attacker can’t be identified beforehand so you know if he’s close enough. So naturally, you can’t rely on remaining safe because you aren’t within range of a criminal – after all, what does a criminal look like?
Fortunately, the fix will be relatively easy to develop in this case and should be forthcoming relatively soon. All that’s necessary is a simple change to the firmware so that during the ‘handshake’ between devices, a unique key is requested every single time, rather than sometimes relying on previously used ones which can be exploited. Get in touch with your provider and ask when fixes will be made available, and as soon as those security updates are released, make sure they are applied to all your devices.
A sandbox is an isolated environment that mimics an entire computer system. This protected space can be used to test suspicious programs and analyze potential threats. Sandboxing is a vital security feature that prevents malware and other viruses from entering and damaging your computer.
Much of the software you already use, like web browsers, have sandboxes that filter most of the code your system uses to perform daily tasks. You can create your own sandboxes to test whether a piece of software is safe, in a controlled environment that won’t damage the rest of your computer’s system.
What Is Sandboxing? Why Is It an Essential Security Feature?
Sandboxes give specific permissions to a piece of code, allowing it to perform its functions, while restricting it to a tightly controlled environment. Programs are then run within this environment, where no additional code permissions can be abused.
In everyday computer use, you come across many sandboxing security techniques. Your web browser, if you use Chrome or Internet Explorer, runs the webpages you visit in a sandbox. These webpages are limited to the access granted by this browser’s sandbox, meaning that this site can’t do things like open your webcam without your permission or snoop on your personal files.
Web Browsers With Sandboxing Capabilities
Browsers with sandboxing capabilities are especially useful for recognizing advanced persistent threats (APTs). These APTs are designed to escape detection, breaking through conventional security barriers, and gaining access to Personally Identifiable Information (PII) on your computer. Sandboxes help isolate these viruses and prevent them from spreading.
Sandboxing browsers don’t have access to your entire computer, because they run in a low-permission mode. If a malicious webpage manages to take over your browser, it would still have to get past the browser’s sandbox to do any damage to rest of your system.
If a webpage happens to contain malicious code, a browser without a sandbox wouldn’t be able to protect the rest of your computer system. This creates a security vulnerability through which malware or viruses can be introduced. Most browsers, with the exception of Mozilla Firefox, have sandboxing capabilities.
For the most part, the fewer permissions granted to the browser or any other program, the more secure your system will be.
Sandboxes Are Already Protecting You
Browsers are among the many sandboxed programs on your computer. There are plenty of other programs that are already being sandboxed for your protection.
Content from plug-ins like Adobe Flash or Microsoft Silverlight are run in sandboxes. An online game made with Flash is much safer when played on a web page than when it’s downloaded and opened as a standard program. As a sandboxed plug-in, Flash contains the game within the browser, and severely restricts what it can do to the rest of your system.
PDFs and Other Documents
PDFs have become a common source of malicious executables. PDFs and other documents can contain malicious embedded links, and without sandboxes, these viruses could compromise your system’s security. Adobe Reader now runs in a sandbox, and Microsoft Office also has sandboxing capabilities that keep unsafe macros from infecting your computer.
Smartphone apps run their code in a sandbox. iOS, Android, and Windows mobile apps have far fewer permissions than their standard desktop counterparts. In order to access functions like your location or camera roll, they must ask for the user’s permission.
By keeping mobile apps in low-permission mode, you’re able to keep the information on your smartphone safe. Sandboxes also isolate apps from each other, so one app can’t affect each another’s functionalities.
If your computer runs on Windows, User Account Control is a form of basic sandbox security that you come across frequently. Essentially, User Account Control restricts desktop applications from modifying files within your system without asking the user for permission.
This form of sandbox security offers very minimal protection, since desktop programs can still run in the background and log your keystrokes. User Account Control merely stops unwanted programs from accessing system files and system-wide settings.
How You Can Apply Sandbox Security to Your Programs
Sandboxing your own programs isn’t really something you need to worry about, since so many of the apps and programs you use on a regular basis are already sandboxed. However, it’s useful to know that most desktop programs aren’t generally sandboxed by default.
If you want to run a program without letting it harm the rest of your system, you can sandbox any program. As mentioned before, User Account Control (UAC) doesn’t do much to protect your system.
Virtual machines like VirtualBox™ or VMware create entire operating systems within your existing OS to test programs. This simulated operating system is completely sandboxed, so it doesn’t have access to the rest of your system, and the programs you are testing within the virtual machine can’t access anything outside of its designated boundaries.
Virtual machines allow you to install programs on the virtual operating system and run them as if they were open on your actual OS. You can then analyze the installed program to determine if it contains malware.
They also have snapshot features, which allow you to reset your virtual machine to state it was before malicious executables were installed. You can then continue to test programs in your virtual machine without worrying about crowding or damaging the virtualized operating system.
Sandboxie, unlike virtual machines, is a program that creates a protective bubble around your existing computer system, effectively sandboxing the parts of your system you specify. With Sandboxie, browsing the web is more secure. Any cookies, cached files, and search history, can all be cleared from your browser when you close the sandbox program. You can even send apps directly to Sandboxie to be examined.

Network Security on Your Home Computer
No matter how much time you spend on your work computer, your home computer contains some of your most important files. Our personal machines help manage our finances, social relationships, and professional lives, but we often don’t put in as much effort into keeping them secure. Our computers contain a variety of personally identifiable information (PII), and it’s important to maintain sound computer and network security to protect your files.
Connecting Your Computer to a Secure Network
A network router is your first point of contact with the Internet. Don’t just rely on your ISP (Internet Service Provider) or cable modem to perform comprehensive security monitoring. An Internet connection starts with your modem, connects to your router, and feeds this information into your computer. Your router should be secure before connecting to the Internet.
Here are a few tips to maintaining network defense, once you are connected to a secure network. First off, use a web browser with sandboxing capabilities. A sandbox is an isolated environment that mimics an entire computer system, which targets suspicious programs and analyzes potential threats.
Browsers with sandboxing capabilities are especially useful for recognizing advanced persistent threats (APTs). These APTs are designed to escape detection, breaking through conventional security barriers, and gaining access to PII on your computer. Sandboxes help capture these viruses and clear them out.
When you own a business, you want to keep your home computers well-defended because any crossover information between work and personal machines, through email or messaging apps, can cause a data breach. A recent study found that 60% of small companies fail due to poor network security measures.
Sandboxing can be applied to a number of different programs, such as PDF readers. A common means for viruses to attack your computer is through embedded URLs, where malicious executables can gain entry via PDF files.
Keep Everything Up-To-Date
While this may seem self-explanatory, many malware attacks occur because personal computers are not as diligently updated as company devices. Make sure your computer has current versions of all software you run.
Updating programs like Microsoft Office to the 2007 version or a more current iteration is a good idea, since word-processing is a common function on home computers. Microsoft Office 2010 offers a “Protected View” that opens documents in read-only mode, which blocks any viruses embedded in unfamiliar files.
Many applications have a feature that enables automatic updates. Updating frequently is a good network security practice, since attackers typically exploit hosts that don’t have their software applications fully patched. Additionally, evaluate which programs you use most frequently and those you never seem to use. Do some research on the software you wish to delete, and determine if removing them is possible. Fewer applications on your computer workstation mean fewer channels for hackers.
Social Engineering and Phishing Attacks
Some of the most common attacks are executed through email. A social engineering attack uses human interaction to obtain sensitive information on computers with vulnerable network security. In these infected emails, a person can claim to be an employee, cleaning service, or someone else offering qualifications that would allow them to gather your confidential information.
Phishing tactics also use emails from attackers masquerading as reliable organizations to obtain personal details. Often, these phishers will take advantage of events in the news (i.e. fake natural disaster fundraisers) and holidays (i.e. Christmas shopping deal scams) to steal account information. They even go so far as to pose as reputable banks to issue fraudulent warnings, hoping that alarmed card holders will hand over their account credentials.
Keeping Your Home Computer Safe From Attacks
To avoid these attacks, install anti-virus and anti-spyware software, firewalls, or email applications that filter your inbox. Whenever you are asked for sensitive information such as your credit card number or even your birthday, verify that your information isn’t falling into the wrong hands.
If you suspect that you’ve received a phishing email, call the organization the message claims to be from. Use the contact info on the legitimate website, and ask about the email.
In general, don’t open unfamiliar links or messages with attachments, especially from email addresses not in your contacts. Also, find out how to build a strong password and employ those methods for all of your accounts. Secure and complex passwords should not only be used for WLANs but also for any devices in your home and work that use web interfaces (i.e. printers, self-automated light switch systems, etc.)
When it comes to protecting your personal information, there’s no such thing as taking too many precautions. At Geek-Aid, we specialize in every kind of cyber security. We all rely heavily on personal computers to manage many aspects of our lives, and keeping these devices secure is a top priority.
Last week, we discussed a couple of habits that will help you protect your computer’s security. Hopefully, you now know how to navigate the internet better and protect your data. In order stay vigilant and protect your computer, there is more that you need to know. After all, there is only so much you can do to keep hackers from trying to access personal information. Let’s discuss how you can check if your computer’s own security methods are in working order.
Keep Your Computer Updated
Computer companies know how troubling hackers can be, for both them and their consumers. They do not want hackers infiltrating the private information of the people who buy their machines. That’s why they constantly update their computer security system to fight off all sorts of viruses, malware, and trojans. The first thing you should do is check if your computer is running the latest update. This will ensure that it is up-to-date and ready to fight off anything trying to penetrate your system.
Scanning Your Settings for Better Protection
There are plenty of useful tools that computer manufacturers release as well. These tools are able to scan your computer for potential problems like weak user passwords or if you are using all of your security features. They can also educate users on the proper security setting for protection against threats. Just remember to download this kind of software straight from your computer’s manufacturer and not untrustworthy sites.
Secure Your Internet Browser
The number one way that hackers gain access to your computer is through the internet. Accidentally opening suspicious emails, clicking random links, or browsing unfamiliar websites can leave you at risk. In order to avoid downloading something malicious, you have to secure your browser’s own security settings. You’ll find that your browser does more than just block pop-up ads. Like your computer, your browser needs to stay updated to protect your system. Your plugins need to stay updated as well. If they remain out of date, then your system is vulnerable.
Make Sure You Have a Strong Firewall
The biggest defense against hackers is your system’s own firewall. Most computers come with a built-in firewall. They block others from penetrating your computer’s files and prevent them from seeing your system online. You have to make sure this computer function is working at optimal efficiency. Try running a port test service. These services are meant to test your firewall and make sure the world cannot see your computer. If it can detect your computer, then it’s very likely that your firewall settings are not correct or that you have a virus.

That way they can not only protect you against viruses or threats but keep your system in working order. We make house calls and service offices as well. So, call us at (877) Geek-Aid to speak with one of our geeks today.
Computers are an essential part of our everyday lives. Whether it’s the cell phone you carry in your pocket or the desktop sitting in your room. They help us work and do our day-to-day task. Without them, our world becomes far less convenient. What is more important than the machine itself is your computer security habits. Protecting your computer from any type of malfunction or malicious attack is important to protect your private data. Let Geek Aid walk you through a couple of ways to ensure you aren’t left vulnerable.
Always Update Your Computer Security
Anytime you boot up your computer, the first thing you should do is check for updates. A new update to your operating system isn’t just an annoying notification that pops up. An update is a vital part of keeping your computer safe. New viruses are born every day, and some hackers even create ones to attack specific operating system. A new update is your computer company’s way to fighting off these infections. The longer you wait to update your system, the more vulnerable you are to an attack.
Change Your Password Game
Over and over we need to remind people to change their passwords. Many use the same password they have been using for several years for every account. This is a bad computer security habit. If your password becomes predictable, you are giving hackers the opportunity to access your devices, personal accounts, and more. Generate random passwords or strong ones that use a combination of letter, numbers, and symbols.
Create Computer Backups
When in doubt, regard Murphy’s law. Anything that can go wrong, will go wrong. As your computer grows older, it’s is more likely to experience random glitches and crashes. You shouldn’t worry too much though as you can prepare for these kinds of unexpected events. Make sure that you regularly create backups. Do it every 2 weeks or every month to make sure the latest information and files are safe and secure. If you need help, there are some useful tips online on how to back up your system.
Email Carefully and Navigate the Web Safely
Going on the internet helps us gather information, stay on top of the news, and do so many other tasks at lightning speed. However, the internet isn’t always safe. Browsing on the web or opening up an unknown email is how a lot of people contract viruses. You have to be more careful. Do not open or download attachments or files from people or sources you don’t trust. Also, shareware and free downloads are often packed with malevolent software.
Investing in Antivirus Software
An extra antivirus software on your machine won’t hurt. In fact, these types of software are your number one barrier against hackers trying to steal or mess with your private data. They can set up firewalls and detect viruses attempting to penetrate your computer’s defense. Do some research and spend some money on a good antivirus software.
It seems harder and harder to protect your computer from security threats and virus. Hackers are constantly trying to gain access to your computer system using the latest tricks and cons. We’ve discussed before how to protect yourself from malicious malware. For example, if you click on a suspicious link in an email, there a good chance you’re inviting a virus to infect your computer. However, a new report suggests it might not be enough. A new virus is now able to infect your computer the moment your mouse hovers over the link.
Malicious Malware Installs Banking Trojan
What’s a Banking Trojan? It’s a type of malware that is designed to break into an online bank account and move a person’s money into a hacker’s bank account. In the U.S., these trojans steal millions of dollars from business and personal accounts. Companies and organization are usually the targets of these nefarious campaigns.
Research by cyber security company Trend Micro and information security blog Dodge This Security revealed a new malware downloader is installing banking Trojans. What makes this particular malware stand out is that users don’t even have to click on anything for it to activate. All users have to do hover their mouse cursor over a hyperlink in a PowerPoint file.
These attacks were largely made against companies and organizations in Europe, the Middle East, and Africa. Hackers sent PowerPoints containing the Trojan via spam email. These emails were disguised as finance-related, making the user believe they were related to a recent order or invoice.
Older computer systems are more at risk than new ones. While the malicious malware does try to automatically download onto your computer, the latest Microsoft Office will ask you beforehand. This provides the user a security measure to prevent the virus from affecting you. However, older versions of Office will execute the PowerPoint file.
Keeping Your Computer Safe
Many companies do not update their computer’s operating system or applications. Working off of older technology leaves them vulnerable to attack and without that added layer of security that they need. Unfortunately, just like we saw with the WannaCry situation, it isn’t so easy for large scale companies to update their computer systems.
A good antivirus software will help to protect your computer from an attack like this. Trend Micro was able to detect 1,444 spam emails last month. Another way to avoid becoming a victim of online theft is by looking out for suspicious emails from unknown senders. These are often the most dangerous types of emails with hackers hoping that you will download its contents.
If you are a small or big business, your computer system is a target. It is best to invest in protecting your company’s private and important information. At Geek Aid, we can assist you with business IT solutions, including:
- Performance Enhancements on Computers
- Crash Repairs
- Data Recovery
- Data Backup
- Security From Thieves and Competitors
- Email Setup
- Technology Consultation

Recently, England’s healthcare system was the victim of a massive cyber attack. The ransomware known as WannaCry locked doctors and employees across at least 25 hospitals out of their networks. Later, it was discovered that the same attack hit multiple organizations across the world. Find out what happened and how it become the largest ransomware attack to date.
What Did WannaCry Demand?
A hacker group known as The Shadow Brokers stole and leaked several Windows’ exploits from the NSA. Within the information leak, a remote code execution vulnerability called ExternalBlue was used to access unsecured computers and install the now infamous ransomware. The computers affected were either not updated or running Windows XP or 2000, which are operating systems that are no longer supported.
The ransomware program is modified version of WannaCrypt, a virus that has plagued computers before. The malicious software locks users from their computers, and then ask them to pay a $300 fee via bitcoin to obtain the encryption key. The longer the user takes to pay the ransom, the higher the fee becomes.
How Did the Virus Make It Onto Computers?
Like many other pieces of malware, WannaCry spread because people didn’t take proper precaution. The virus is believed to have originated from compressed files attached to emails. It’s important to avoid becoming an online victim. This is a topic that we have discussed before because there are a lot of opportunistic groups looking to take advantage of internet users.
Why Are Small and Large Businesses Using Vulnerable Systems?
Upgrading to the newest operating system is not so simple for business. For example, the UK’s National Health Service (NHS) notes that medical equipment uses old operating systems and are not easy to update. Business with multiple computers or larger IT system can also have a hard time updating their infrastructure. Some updates can break key application needed to do work. Companies have to be very careful when performing a companywide update, otherwise, it can critically damage everyone.
While Microsoft has ended support for older operating systems, they recently created a patch to address the incident. Companies using Windows XP, Windows 8, and Windows Server 2003 can now download a patch to protect their computers. If you can, we suggest updating your operating system regularly to avoid risk to your private information.

How many times have you come across a website’s contact form to be met with a reCAPTCHA field at the end? We’re also sure that you are familiar with clicking that little “I’m not a robot” box as well. Have you ever wondered what this section is for? Well, as the little box says, it’s to make sure that you are not some robot looking to spam the website owner’s email.
A reCAPTCHA field makes sure that actual people are submitting a request to you. It makes it impossible for a malicious program to enter information into your contact form and send you unwanted messages, or worse, viruses. In 2009, Google acquired this technology and now they are giving it a much-needed upgrade.
How reCAPTCHA Used to Work
The reCAPTCHA program has seen various updates over the years. In the beginning, the system displayed an image where the letters were made up from several photos. It would form two different words that usually had no correlation with one another. Users would then type those words in and click the “I’m not a robot” box to complete the form.
As time moved on and Google acquired the technology, they begin finding new ways to circumnavigate updated robots. Around 2012, they started used photos with house number acquired from Google street view. Two years later, they changed the system by having users identify certain photos in a group of pictures.
What Is the Invisible reCAPTCHA?
This year, Google is rolling out what seems to be the ultimate update to its anti-spam technology. It requires almost no user interaction at all … unless you are displaying suspicious behavior.
Back in 2014, the company created the noCAPTCHA reCAPTCHA. This eliminated all of the tests and security tricky fields meant to keep away sophisticated robots. All users needed to do was check the “I’m not a robot” box and submit their request. How was this new system more secure than previous versions? That’s pretty easy to understand.
Using its new learning and improved risk analysis engine, the system analyzes your browsing behavior. If it believes that you are a human, then you will be able to fill out your form without going through a variety of security fields. However, if it can’t accurately predict your behavior, the engine will see you as suspicious. As a result, it will present you with the CAPTCHA that you are normally used to filling out.
The latest update seeks to eliminate user interactions with the reCAPTCHA altogether. Even the “I’m not a robot” box no longer appears on the user’s screen. Users simply fill out the contact form. This new tech is constantly learning. The more people who fill out contact forms, the more the system is able to determine the difference between someone who it real and one who isn’t.
The “Invisible reCAPTCHA” is set to release sometime this year.
