It’s every business user’s responsibility to protect their computers and data from cyberattacks. The good news is that you don’t need to be an IT security expert to keep them safe. You can start increasing your knowledge by learning some of these basic cybersecurity terms.

Malware

For a long time, the phrase “computer virus” was misused to refer to every type of attack that intended to harm or hurt computers and networks. The more appropriate term for these harmful programs and files would be “malicious software” or “malware.” Whereas a virus is a specific type of malware that is designed to replicate itself, any software created for the purpose of destroying or unfairly accessing networks and data should be referred to as malware.

Ransomware

Don’t let all other cyberthreats ending in -ware confuse you; they are all just subcategories of malware. Currently, one of the most popular of these is “ransomware,” which is malware that encrypts valuable data until a ransom is paid.

Intrusion prevention system (IPS)

There are several ways to safeguard your network from malware, but an IPS is quickly becoming one of the nonnegotiables. An IPS sits inside your company’s firewall and looks for suspicious and malicious activity that can be halted before it can exploit or take advantage of a known vulnerability.

Social engineering

Not all types of malware rely solely on fancy computer programming. Experts agree that the majority of attacks require some form of “social engineering” to succeed. Social engineering is the act of tricking people, rather than computers, into revealing sensitive or protected information. For cybercriminals, complicated software is totally unnecessary if they can just convince potential victims that they’re a security professional who needs the victims’ password to secure their account.

Phishing

Despite often relying on face-to-face interactions, social engineering does occasionally employ more technical methods. Phishing is the act of defrauding people using an app or a website that impersonates a trustworthy or often well-known business in an attempt to obtain confidential information. Just because you received an email that says it’s from the IRS doesn’t mean that it is. Don’t take such emails at face value — always verify the source, especially if the emails are requesting your sensitive data.

Antivirus

Antivirus software is often misunderstood as a way to comprehensively secure your computers and workstations. These applications are just one piece of the cybersecurity puzzle and can only scan the drives on which they are installed for signs of well-known malware variants.

Zero-day attacks

Malware is most dangerous when it has been released but not yet discovered by cybersecurity experts. When a vulnerability is found within a piece of software, vendors will release an update to fix the gap in security. However, if cyberattackers release a piece of malware that has never been seen before, and if that malware exploits one of these holes before the vulnerability is addressed, it is called a zero-day attack.

Patch

When software developers discover a security vulnerability in their programming, they usually release a small file to update and “patch” this gap. Patches are essential to keeping your network secure from the vultures lurking on the internet. By checking for and installing patches as often as possible, you keep your software protected from the latest malware.

Redundant data

When antivirus software, patches, and intrusion prevention fail to keep your information secure, there’s only one thing that will: quarantined off-site storage. Duplicating your data offline and storing it somewhere other than your business’s workspace ensures that if there is a malware infection, you’re equipped with backups.

Our cybersecurity professionals are always available to impart more in-depth knowledge of the many different kinds of cyberthreats. Get in touch with us today and find out how we can help you with your IT security woes.

Many businesses prefer Microsoft 365 not only because of its powerful features and cost-saving benefits, but also because of its world-class security. However, the cyberthreat landscape is constantly evolving, so using this suite of cloud-based tools and services will always come with security challenges. Fortunately, Microsoft is continuously looking for ways to address these issues to ensure that your environment and data are protected.

Vulnerabilities in SharePoint

Businesses typically use SharePoint Online and on-premises SharePoint sites to store sensitive information like personally identifiable data. Failing to secure SharePoint content against unauthorized users is one way to expose data and your business to malicious actors. This can be critical for companies that are required to comply with stringent data privacy and protection regulations and may face serious consequences for noncompliance.

To prevent this, limit administrator-level privileges and enable encryption. Additionally, set the necessary security restrictions per user for every application.

Unprotected communication channels

Phishing attacks and malware are two of the most common ways cybercriminals infiltrate a system, but there are other paths of attack. Microsoft 365 applications like Microsoft Teams, which can connect to external networks, may serve as a medium for ransomware and other types of attack.

Train your staff to identify potentially malicious files and links. Also, offer guidelines on how to handle and route sensitive files and communication to safe locations.

Security risks in dormant applications

Organizations using Microsoft 365 often won’t use all the tools and services included in the productivity suite. You may use one or several programs like Word, Excel, and SharePoint but rarely use OneDrive. If your business has been utilizing specific programs, note that some dormant applications may be prone to attack. This is why it’s crucial to identify the apps that aren’t being used, and have an administrator tweak user settings to restrict availability on such apps.

File synchronization

Like most cloud services, Microsoft 365 allows users to automatically sync on-premises files to the cloud, such as in OneDrive. This useful feature is not without security risks, however. If a file stored locally is infected with malware, OneDrive will view the file as changed/updated and trigger a sync to the OneDrive cloud, with the infection going undetected.

Office 365 Cloud App Security, a subset of Microsoft Cloud App Security, is designed to enhance protections for Office 365 apps and provide great visibility into user activity to improve incident response efforts. Make sure your organization’s security administrators set it up on your systems so you can detect and mitigate cyber risks as soon as possible.

Cybercriminals will continue to sharpen their hacking techniques, and your organization must keep up to protect your systems, apps, and devices. Call our team of IT experts now if you want to strengthen your business IT security.

Ransomware is on the rise, but falling victim to one is not the end of the world. You can try some of these ransomware decryptors and maybe one of them will work. These are especially useful against automated “zombie” ransomware types.

The state of ransomware in 2021 so far

Businesses need to deal with ransomware both from outside and within. On one hand, there are more cybercriminals trying to infiltrate your network. On the other hand, careless and unknowing staff can easily let ransomware enter your network. For instance, employees may be tricked into providing their access credentials in phishing sites, or they may click links to websites that upload ransomware downloaders onto their machines.

The statistics are sobering. Ransomware cost businesses more than $75 billion per year. Over the past two years, ransomware attacks have increased by over 97%. And compared to the first two months of 2017, ransomware campaigns that were initiated from phishing emails increased by 109% in the same span of time this year.
According to studies, there will be a ransomware attack targeting a business every 11 seconds in 2021. That is up from every 14 seconds in 2019, and every 40 seconds in 2016. And the trend is that the rate will continue to increase over the years.

Zombie ransomware is easy to defeat

Not every type of infection is targeted to individual organizations. Some infections may result from self-propagating ransomware strains, while others may come from cyberattackers who are hoping targets become so scared that they pay up before doing any research on how dated the strain is and how to remove it.

No matter what the circumstances of your infection are, always check the following lists to see whether free decryption tools have been released to save you a world of hurt:

Prevention

But even when you can get your data back for free, getting hit with ransomware is no walk in the park. There are essentially three basic approaches to prevent ransomware:

  • First, train your employees about what they should and shouldn’t open when browsing the web and checking email.
  • Second, back up your data as often as possible to quarantined storage. As long as access to your backed-up data is extremely limited and not directly connected to your network, you should be able to restore everything in case of an infection.
  • Finally, regularly update all your software solutions (operating systems, productivity software, and antivirus). Most big-name vendors are quick to patch vulnerabilities, and you’ll prevent a large portion of infections just by staying up to date.

Whether it’s dealing with an infection or preventing one, the best option is to always seek professional advice from seasoned IT technicians. It’s possible that you could decrypt your data with the tools listed above, but most ransomware strains destroy your data after a set time limit, and you may not be able to beat the clock. And even if you do, you probably won’t have the expertise to discern where your security was penetrated.

Don’t waste time fighting a never-ending stream of cyberattacks — hand it over to us and be done with it. Call us today to find out more.

Google Play recently removed 17 apps identified by security company Zscaler to contain malicious adware code. These apps bombard users with unwanted advertisements and collect marketing-type data about them. If you’re one of the thousands of users worldwide who downloaded at least one of these apps, here’s a quick guide to finding and uninstalling them.

Sneaky adware apps

These potentially malicious apps are disguised as harmless system or utility apps. They pose as image editors, photo or document scanners, and even messenger apps. Their names even resemble those of legitimate system apps, chosen for the express purpose of tricking Android users into installing them onto their devices. These apps are:

  1. All Good PDF Scanner
  2. Blue Scanner
  3. Care Message
  4. Desire Translate
  5. Direct Messenger
  6. Hummingbird PDF Converter – Photo to PDF
  7. Meticulous Scanner
  8. Mint Leaf Message-Your Private Message
  9. One Sentence Translator – Multifunctional Translator
  10. Paper Doc Scanner
  11. Part Message
  12. Powerful Cleaner
  13. Private SMS
  14. Style Photo Collage
  15. Talent Photo Editor – Blur focus
  16. Tangram App Lock
  17. Unique Keyboard – Fancy Fonts & Free Emoticons

How to remove these adware apps

It’s important that you immediately remove these apps from your device to prevent them from exposing you to all kinds of IT security threats, like man-in-the-middle attacks. One way to do this is to use an anti-malware app that scans and automatically removes malicious software from your device. You can also check your phone or tablet’s app permissions to see if any questionable apps have permission to access your text messages, contact list, etc., and manually uninstall the dubious apps.

However, some apps are harder to detect because they display two different sets of names and icons — one on your device’s Settings app and another when they’re actually running. This makes it more difficult to identify and uninstall the malicious apps on your device, which is exactly what the developers want.

On the other hand, some apps appear on your app tray, but launching one triggers a message that says the app is incompatible with your device. You will then be redirected to a random page on Google Play. And when you return to your app tray, you’ll find that the app’s icon has disappeared.

If there’s no icon, how can you uninstall the app? Andrew Brandt, a researcher at Sophos, says deleting adware apps will require a little bit of digging on your part, as there’s no icon that you can click and drag to the top of the screen and into the trash.

To do this, you have to first identify the adware apps. Go to Settings > Apps & Notifications. This will direct you to a page that displays the most recently opened apps on your device. Next, check if any of those apps have the generic greenish-blue Android icon and/or have generic-sounding names such as Back Up, Update, and the like. If they do, they’re likely adware. Finally, tap the icon and then select Force Stop > Uninstall. Note that a legit system or utility app will have a Disable option instead of an Uninstall option.

There may be similar apps that are yet to be identified and are likely to be made available on Google Play in the future. The key takeaway here is to be mindful of what you download, even if it’s from Google Play or other official platforms. Check out the reviews — the reported adware apps got poor reviews from users who complained about getting a lot of pop-up ads.

Remember that malware can be hiding in even the most innocuous apps, and downloading them gives bad actors the chance to access any confidential information on your device. For advice on how to keep your Android devices safe from adware and other malicious malware, give us a call today.

The Android operating system is open source, which makes customization and app development easy. The problem is that cybercriminals can also access Android’s programming code, find vulnerabilities, and distribute malware through app stores. Here are some things you must do to avoid an infection.

Confirm the malware infection

Android devices usually exhibit strange behaviors when they’re infected with malware. A device may suddenly slow to a crawl or the battery may drain faster than expected. Other telltale signs include an abundance of pop-up ads, unusual apps installed on your home screen, unexplained data usage, and unauthorized in-app purchases.

However, it’s not always easy to tell if your device was compromised, especially since hackers are becoming more proficient at concealing their actions. The best way to check for malware is to run an antivirus scan with a mobile security solution.

How to get rid of malware

If malware has infected your device, the most important thing to do is quarantine the threat as soon as possible. Start by rebooting your device in safe mode, which can be selected when you hold down the power button. Not all versions of Android are the same though, so if this isn’t an option, try restarting your device and holding the volume-down button when the manufacturer’s logo appears.

Once you’ve entered safe mode, go to Settings, then Apps, and uninstall any suspicious apps. A quick Google search or a conversation with your cybersecurity technician should help you determine whether or not an app is dangerous.

If you can’t uninstall the software, it might have administrative privileges. To fix this, open the Advanced settings menu from the Settings app, then select Security, then Device administrators, remove any app that shouldn’t have privileged access, and return to the Apps menu to uninstall it. Mobile security software should also be able to remove malicious programs hiding in your device.

If the malware persists, you’ll have to do a factory reset. This option is usually located in the Backup & reset configurations within the Advanced settings menu. Keep in mind that you’ll lose the apps and files stored in your device, so it’s important to back up your data beforehand.

Protecting your device from malware

After you’ve successfully recovered from a mobile malware infection, make sure to update your device and security software to prevent another infection. Enabling Google Play Protect from within the app store also safeguards your device from rogue apps.

When all is said and done, the best defense is to develop good security habits. Be cautious of everything you see online. Make sure to thoroughly vet apps before downloading them and don’t click on links from unsolicited texts and emails. Also, avoid public Wi-Fi networks or, at the very least, use a virtual private network (VPN) to secure the connection.

Malware attacks can be devastating to your bottom line, but these tips should mitigate the risks. If you want to learn more about how you can safeguard your Android devices, our experts are always willing to assist you. Contact us today.

With the rise of eCommerce and online banking, cybercrime has evolved. Like criminals who pull smash-and-grab jobs, they go where the money is. However, unlike bank robbers, cybercriminals do their best to avoid detection by letting malware do the work for them. Viruses and ransomware sneak into PCs to quietly steal passwords, financial credentials, and other personal information to be sold on the black market for profit. Not all malware is stealthy though. Here are some telltale signs.

Slow computer

Are your operating systems and programs taking a while to start up? Is your data bandwidth suspiciously slow? If so, your computer may potentially have a virus.

However, just because your PC is running slower than usual doesn’t necessarily mean that it’s infected, as there could be other causes to your computer slowing down. First, check if you’re running out of RAM. For Windows, open task manager (press Ctrl + Shift + Esc) and go to the Performance tab and check how many gigabytes of RAM are used up under the Memory section. For Mac OS users, you can open the Activity Monitor app and, under System Memory, you should be able to find out your RAM usage.

Other causes could include lack of space on your hard drive or even damaged hardware. Once you’ve ruled out other possible causes, then malware may have infected your device.

Blue screen of death (BSOD)

If your PC crashes regularly, it’s usually either a technical problem with your system or a malware infection. You might not have installed the latest drivers for your device or the programs you’re running could possibly be incompatible with your hardware. If none of these problems are apparent in your PC, then a virus could be clashing with other programs and causing your crashes.

To check what caused your last BSOD, go to Control Panel > System and Security > Administrative Tools > Event Viewer and select Windows Logs. Those marked with “error” are your recorded crashes. For troubleshooting solutions, consult forums or your IT department to figure out what to do next.

Lack of storage space

There are several types of malware that can manipulate and corrupt the files saved on your computer. Most tend to fill up your hard drive with suspicious files. Ransomware, for example, is a notorious type of malware that denies you access to your data until you pay a so-called ransom. There are more aggressive forms of ransomware, like NotPetya, known for exploiting security holes to infect computers without needing to trick users.

If you find any unknown programs that you have never installed before, notify IT personnel in person immediately (do not email them) and have them handle the situation for you. Your device might not be the only one in your network that is infected with suspicious programs.

Suspicious modem and hard drive activity

Combined with the other warning signs, if your hard disk is working excessively while no programs are currently running or if you notice that your external modem is always lit, then you should scan your computer for viruses.

Pop-ups, websites, toolbars, and other unwanted programs

Pop-ups come from clicking on suspicious pages, such as those where users are asked to answer survey questions to access a website’s service or install free applications. While they’re inherently harmless, they could be downright annoying. Refrain from clicking pop-up pages and just close them instead. Run malware scans and update your browsers.

You might think that downloading free applications is harmless, but the installation process can inject malware into your device. When you’re installing a program from the internet or even app stores, it’s easy to just skim over the terms and conditions page and repeatedly press next. This is where they get you. In the process of skipping over certain installation steps, you might have agreed to accepting a new default browser and opening unwanted websites and other programs filled with viruses. Be cautious when downloading something for free.

You’re sending out spam

If your friends are telling you that you’ve been sending them suspicious messages and links over social media or email, you might be a victim of spyware. Warn your friends not to open anything that appears to be spam and make sure to reset your passwords across all your devices and enable multifactor authentication.

Knowing how malicious software affects your computer can help you take the necessary precautions and steps to rectify the situation as soon as possible. Regardless of whether or not your system has experienced these symptoms, it’s always smart to perform regular malware scans to ensure your business is safe.

Although the occasional three-minute YouTube video never hurts anyone, wasting hours of your working day on these websites reduces productivity. When it comes to increasing employee productivity, keeping a close eye on their internet behavior reaps various benefits.

Time-saving measures

Internet monitoring software saves employees from visiting entertainment, gaming, or online shopping sites by restricting access to them. Internet monitoring software doesn’t necessarily block access to social media sites, but it lets your employees know that you’re monitoring their internet activity. This is aimed at discouraging them from taking prolonged visits to their Facebook, Twitter or Instagram page.

Avoid harmful websites

The internet hosts plenty of unsavory links and websites. Employees who haphazardly click phishing links or access malware-ridden pornography sites can put your business at risk. Working with infected machines can slow down the entire system and, in some cases, completely halt operations. By using internet monitoring tools, you can restrict access to dangerous websites and identify reckless employees who access them and remove their internet privileges, if necessary.

Control bandwidth usage

Even while using the internet for the right purposes, bandwidth can be used up quickly. Internet monitoring gives you up-to-the-minute reports on staff’s bandwidth usage. Once you have a clear understanding of your company’s overall bandwidth usage, you can better control internet expenditure. Ultimately, this feature allows you to prioritize bandwidth for critical business applications and reduce bandwidth for less necessary websites.

Increase productivity on the internet

Internet monitoring software may be a powerful tool, but it should be used responsibly. As a business owner, you need to walk a fine line between over-surveillance and under-surveillance. What you should do is establish a clear internet policy, which should explicitly define the disciplinary measures to be dispensed on anybody who goes against the company’s internet policy. You should also deal with time-wasting employees on a case-by-case basis because it’s unreasonable to remove everyone’s Facebook privileges because one or two abused theirs.

Employee productivity can be difficult to achieve, especially with the proliferation of the so-called “procrastination software.” But with web monitoring software, you can truly get your business — and your employees — back on track. Looking for more ways to increase business productivity with technology? Give us a call. We’ll be happy to make suggestions.

With evolving technology comes evolving threats. Recently, a researcher revealed that a new type of scam freezes Google Chrome and tricks users into believing that their network security has been compromised. Little did they know that following instructions listed on the screen will lead to an actual security breach.

The End Game

The scam works by displaying an error message indicating a bogus security breach incident that renders a browser unusable. These scammers capitalize on the fact that a serious crash can’t be solved by simply closing the site, thereby sending the users into a panic. This encourages them to dial the number listed on the warning message.

On the other end of the line, the scammers would pose as Microsoft or Apple representatives to convince users into surrendering their credit card details to repair a non-existing security issue. The scams are generally carried out through legitimate sites or malicious ads that have been hacked.

The Ingenious Process

This new scam operates against Chrome by corrupting the window.navigator.msSaveOrOpenBlob programming interface, which basically uses it as a form of distraction. The hackers manipulate the browser and forces it to save a random document on a disk repeatedly at super fast intervals that are impossible to notice. After five to 10 seconds, Chrome will be completely unresponsive.

The Easy Fix

To recover, Windows users simply have to open Windows Task Manager (press ctrl + shift + esc keys) and stop the process there. On the other hand, macOS users just need to wait until a system message prompts them to close the unresponsive Chrome tab. Typically, the latter is a more appealing option since users would have the freedom to close only the corrupted page. Manually closing the whole browser means possibly losing unsaved files in any open Windows.

When faced with IT-related issues, you need to determine how you can approach them calmly. The threats in the digital world may be terrifying and intimidating, but causing a panic in your workplace isn’t the answer. Call us as soon as any problems arise, and we’ll help you as soon as we can. We can even hook you up with other security measures to beef up your network security.

Cryptocurrencies like Bitcoin and Monero are so popular because they’re secure and potentially worth thousands of dollars. But investors and consumers aren’t the only ones interested in them. Hackers are using malicious tactics to steal cryptocurrency, and they’re doing it with something called cryptojacking.

Hijacked hardware
Cryptojacking secretly uses your computer to calculate complex mathematical problems to generate cryptocurrency. They get inside by using phishing emails to lure victims into clicking on a link, which then runs malicious cryptomining programs on the computer. Any cryptocurrency produced then gets delivered to the hacker’s private server.

But hackers have developed an even more insidious tactic. By infecting websites with ads and plugins that run cryptojacking code, any visitor who loads the web page instantly gets infected with the malware, sending their computer’s processor into overdrive trying to generate cryptocurrency.

Unlike most malware, cryptojacking software won’t compromise your data. But it will hijack your hardware’s processing power, decreasing performance while increasing your power and cooling bills. So instead of paying for the computing power themselves, hackers can simply use thousands of compromised computers.

Surge in cryptojacking
It’s difficult to tell how much hackers are making with cryptojacking, but there’s a good chance that this type of attack will be as popular as ransomware was in 2017. In fact, for as little as $30, anyone can purchase a cryptojacking kit from the dark web to force other computers to generate Bitcoin or Monero for them.

According to several reports, even sites like The Pirate Bay, Openload, and OnlineVideoConverter are allegedly using cryptojacking exploits to diversify their revenue streams.

The biggest reason why this is becoming so popular is because it’s a low-risk, high-reward scheme. Instead of extorting money directly from the victim, hackers can secretly generate digital currencies without the victim knowing.

If it is detected, it’s also very hard to track down who initiated the attack. And since nothing was actually “stolen” (other than a portion of computing power), victims have little incentive to apprehend the culprit.

Prevention and response
To avoid cryptojacking, you need to incorporate it into your monthly security training sessions. Teach your employees to practice extra caution with unsolicited emails and suspicious links. Using ad-blocker or anti-cryptomining extensions on web browsers is also a great way to stay protected.

Beyond prevention, use network monitoring solutions to detect any unusual behavior with your computers. For example, if you notice a significant number of PCs running slower than usual, you should assume that cryptojacking is taking place.

If you’ve confirmed that it is, advise your staff to close browser tabs and update browser extensions as soon as possible.

Cryptojacking may seem less threatening than some malware we’ve discussed in the past, but it can incur real power, cooling, and performance costs to your business when several systems are compromised. To make sure you don’t end up enriching any hackers, call us today. We offer hardware solutions and cybersecurity tips to keep your business safe and sound.

Traditional ransomware like WannaCry has been explained a thousand ways on a thousand blogs. But one thing you may not have thought about is what ransomware would be like if it infected your mobile device. Read on to learn more.

How does ransomware make it onto your Android device?

Like its desktop equivalent, mobile ransomware needs to be installed on your device before it can do damage. For Android devices, this means mobile apps that hide their true intent. There are two ways to install programs on your mobile device: downloading them from app stores like Google Play and Amazon Appstore, or downloading them directly from websites and email links.

Surprisingly, both come with risks. Unverified sources often advertise free apps that hide malware, and the best of these can occasionally avoid detection and be allowed into monitored app stores.

What does mobile ransomware look like?

Similar to ransomware on personal computers, mobile ransomware holds data stored on your device hostage and demands ransom. For example, in the case of a ransomware that came with the “OK” app, a popular Russian social network platform that was infected earlier this year, a user is prompted to change device settings. There is no option to close the prompt and tapping Accept locks everything down and leaves you with nothing but a ransom note.

How to protect yourself from mobile ransomware

First and foremost, avoid downloading apps directly from websites or third-party app stores. Additionally, make sure you turn on Google’s security system — Verify Apps — which scans all the apps about to be installed on your device for potential threats. You can do so by opening your Android’s settings, choosing Security, tapping on Verify Apps, and activating ‘Scan device for security threats’.

Second, install antivirus software on your device and keep it up to date.

Third, back up important files from your device to either a USB disk, a computer, or any cloud-based services. This way, you won’t lose your valuable data if you are forced to factory-reset your device.

Last, if ransomware made its way into your device, don’t pay. According to IT security company ESET, mobile ransomware very rarely includes programming to reverse the damage it has done.

Losing any type of data is an enormous inconvenience, but businesses need to be especially careful about careless employees. Data loss could result in lawsuits or regulatory fines, so it’s important that you know how to safeguard your Android against ransomware.
