What Is the Cloud?
“The cloud” is one of those popular tech topics people talk about but can’t always define. The cloud is essentially a network of servers that does two types of things. One kind of cloud server stores data and while the other uses its computing power to help applications run.
We all come across the cloud frequently in everyday life, especially for storage. Every time you use an app like Instagram, a cloud server is what holds the pictures uploaded to your account. These photos are not saved in your phone’s internal memory, but rather in Instagram’s network of servers. Dropbox is also an example of a cloud server. Every time you save something on your computer that doesn’t take up your computer’s memory, you are using the cloud.
Other companies like Adobe use the cloud to deliver services. Previously you could buy the Adobe Creative Suite™ in a physical box. Now, all of these tools exist in the cloud and users pay a subscription fee to access them in the Adobe Creative Cloud™.
How the Cloud Benefits You
When businesses decide to move their resources to the cloud, overhead costs can be reduced. Before cloud technology became widespread, businesses would have to purchase hardware and computer applications that lost their value over time. With the cloud, applications previously downloaded on physical computers are now run and updated through the Internet.
Businesses can also be more flexible with their resources. The cloud allows them to pay for only what they use since cloud computing is a subscription-based service. It can also accommodate for businesses that have growing bandwidth demands since cloud capacity can be scaled up and down easily. This kind of agility makes these services cost-effective and adaptive.
The cloud can make your business more secure in a variety of ways. Lost laptops are a security breach for companies every year because many of them contain highly sensitive information. Not only that, valuable documents may be lost forever when devices are misplaced.
With cloud computing, you can access files at any time via your Internet connection. This allows you to remotely wipe the memory of lost devices and not have to worry about information falling into the wrong hands.
The cloud benefits the environment by decreasing your carbon footprint, by reducing unnecessary hardware and only using the required amount of cloud storage. Even in the digital age where more and more companies are going paperless, sustainability is important.
Is the Cloud Secure?
Contrary to popular belief, the cloud is quite secure. However, it requires you to take measures to personally secure your company’s data. When businesses “move to the cloud,” it requires that you have knowledgeable security staff that understands what that entails. Your team must know that the data you are moving is sensitive, and apply end-to-end encryption to the data during both storage and transfer process.
A recent study found that 82% of public databases are not encrypted. Make sure the cloud provider you are using suits your data needs and has what it takes to keep your files secure. Whatever service you choose, it is still the job of the user to define who can access the data, move it, add data, etc., and how those permissions change with each cloud provider. Defining these terms is known as Identity Access Management (IAM).
In addition to these steps, it is wise to back up your data in separate fault domains. Fault domains are basically stacks of servers. They include features that, in the case of a network failure, make sure only the server with the failure would stop working. This means you have multiple copies of your data, achieving maximum file resiliency.
Cloud Computing Creates a Level Playing Field
Anyone can utilize cloud computing services since they are inexpensive and require only an Internet connection to access. It also allows small and growing companies to use enterprise-level technology, and even make faster business decisions than larger, more established companies.
Cloud networks facilitate collaboration from your team members, meaning that they can work and share files with everyone, from anywhere. Cloud-based workflow applications allow real-time remote collaboration and streamline communication. Gone are the days of attaching files to emails and ending up with incompatible file formats, and ineffective version-control.
Moving data to the cloud means that even the smallest companies are becoming more globally involved. Since growing businesses can be financially nimble using cloud computing services, they can now disrupt a market dominated by Fortune 500 corporations.

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.

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

There appears to be no rest for the world of cyber security. Hackers are vigilant and in order to keep the personal and private information of the public safe, cyber security experts must be as well. A popular target for hackers are smartphones and other mobile devices. As people rely more and more on this form of technology for everyday task, the more likely they become a victim of security threats. The companies who create these devices constantly update them to prevent such events. However, hackers are crafty. For example, their newest method to hack your phone involves using cutting-edge voice hacking.
Mimicking You Through Voice Hacking
While still in its infancy, sending commands to your smartphone or mobile device via voice controls is on the rise. Digital assistants like Siri, Cortana, Alexa, and others are becoming an essential part of the user experience. Even Apple has dedicated their time to updating Siri with a better intelligence.
What’s troublesome is that hackers can record audio samples while you are engaging with these digital assistants. They are able to mimic your voice, convincing other that they are you. This malicious technology allows hackers access to personal accounts and security mechanisms.
In an interview with Forbes, Yuval Ben-Itzhak, chief technology officer at AVG, warns against using speech recognition apps, recommending that users disable them right away. “At the moment, leaving biometric technology as it is today is like leaving a computer without a password and just allowing anyone to walk by, click and take an action,” says Ben-Itzhak.
Stopping Voice Hacking in Its Tracks
The researchers at the University at Buffalo have the same thoughts as Ben-Itzhak. That’s why they’ve developed a way to detect and prevent hackers from using obtaining your voice patterns. The engineers were able to create an app that stops voice hacking using a smartphone’s existing components.
“Technology is advancing so fast; we have to think of different ways. The strategy is using multiple lines of defense. We call that defense in depth,” says Kui Ren, Ph.D., director of the Ubiquitous Security and Privacy Research Laboratory (UbiSeC) at UB, and one of the study’s lead authors.
Ren and his team’s study focused on hackers replaying someone’s voice to access a device. Hackers will use speakers to perform such a task. The app uses the following tools:
- A magnetometer in a phone to detect the speaker’s magnetic field.
- The phone’s trajectory mapping algorithm to measure the distance between the speaker and the phone.
The app also uses movement to detect the difference between a person and a replayed voice, the latter’s magnetic field changes when moved.
“We cannot decide if voice authentication will be pervasive in the future. It might be. We’re already seeing the increasing trend,” Ren said. “And if that is the case, we have to defend against voice replay attacks. Otherwise, voice authentication cannot be secure.”
This research is crucial to keeping digital users safe. Some technology already exists that prevent other forms of voice hacking from occurring. Hopefully, people will soon be able to add the University at Buffalo’s app to their phone’s security.
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.

The government’s stance on the future of the internet has forced several states to take action. In preparation for a possible roll back on the Obama administration’s standing rules, states are making laws of their own. Nevada’s Senate takes the side of those who are for the protection of internet users by introducing Senate Bill 538. This bill hopes to protect the online privacy of Internet users by requiring websites to notify users when they are collecting personal data.
What Is the Bill Trying to Prevent?
The Republican-led government recently voted to roll back the FCC’s privacy regulations. These rules made it mandatory for internet service providers (ISPs) to get your permission before selling your personal data. The House of Representative new bill would allow ISPs to collect and sell information about your browsing history and present users with unwanted advertisements. President Trump has made it known that he is in support of the resolution and plans to sign it.
Nevada’s Bill to Protect Internet Users
The state of Nevada hopes to keep the old rules alive by implementing their variation of the law. Nevada is not the only state either. Other states like Seattle are creating similar bills to protect online privacy, an act that shows their opposition to the current government landscape.
Senate bill 538 states that it is “AN ACT relating to Internet privacy; requiring the operator of an Internet website or online service which collects certain information from residents of this State to provide notice of certain provisions relating to the privacy of the information collected by the operator; and providing other matters properly relating thereto.” The bill also lists several rules that lay out what ISPs can and cannot do.
What Measures Are Consumers Taking?
Nevada’s new bill can potential prevent ISPs from taking advantage of internet users. On the other hand, these rules don’t apply to the rest of the country. Informed consumers are taking matters into their hands by investing in a VPN. A VPN is a way of hiding your activity from ISPs by encrypting your internet connection. Essentially, the only information that your ISP will see is you visiting the VPN, not your internet activity.
The problem with VPNs is that a good one is hard to find. Most VPNs are not as secure as one thinks. Some of these services have even been caught selling the very information that they are responsible for protecting. It is best to do extensive research before purchasing to find out about the company’s background.
The Future of Online Privacy
The FCC’s new Chairman, Ajit Pai, still seeks to move online privacy regulations to the FTC. Without ISP rules, the FCC is hoping that the providers will act in good faith, without betraying the trust of their customers. However, users believe that these service providers will take advantage of an unregulated internet. With many in disagreement with the Trump administration, we may see more and more states making their rules to protect online users.
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.
At one point or another, all of us have problems with our computer. The wonderful machine that allows us to do work, browse the interwebs and do a myriad of other things sometimes malfunctions beyond our understanding. At that point, we are calling the computer manufacture only for them to ask us if we tried turning it on and off.
Some of the issues we encounter can be serious threats. Other times, they are simply common computer problems. As a user, you should know how to identify between the two and what to do when you encounter them.
Keeping Your Computer Security Up-to-Date
Viruses and spyware are often a user’s number one concern – as it should be. Online threats are more prevalent today than they have ever been. Your computer’s behavior is a telling sign. Look out for anything peculiar that doesn’t normally happen with your machine. More than likely, your computer is being affected by some kind of malware that you accidently downloaded.
Antivirus software is your best defense against malicious programs. These programs generally work to protect your computer from the latest threats. However, viruses and spyware evolve to work around your computer’s protection software. You have to keep your antivirus software updated. Once you have updated your computer’s security software, run a comprehensive scan. It will weed out any threats to your privacy.
Dealing With Common Computer Problems
If you are experiencing issues with your computer, it will usually tell you. Error messages with alert you of an action that cannot be completed or if you are doing something that conflicts with another program. Sometimes, a computer will only give you the error code, leaving you stumped and confused. A simple Google search will provide you with the answer to the problem. Follow the instruction given to you and everything should be in working order.
If your computer is running slow, check your local disk space. You could have too much saved on your hard drive. Look through your files and erase anything you don’t need. You could also have too many programs running in the background. Go into your settings and open the privacy section. Next, you’ll find a section labeled “Background Apps.” You can turn on and off apps as you see fit.
Preventing Future Incidents
Your computer is an important tool. That’s why you need to be more careful online. When you are browsing the internet, stay away from shady and untrustworthy sites. Also, beware for freeware apps that promise you a service that you would normally have to pay for.
Also, remember that computers can be dumb. Certain parts of your operating system may break or are plagued by a bug. That is why companies release weekly updates. They eradicate common issues that interfere with your computer.
Hopefully, you now have a better idea of what is happening with your computer and if they are just common computer problems. If there are any issues that are beyond your control, then call us at Geek Aid. We are here to solve all of your computer repair issues.
