You’ve all heard of viruses, spyware, ransomware and trojans. But did you know that they’re all types of malware? They’re all designed to ruin your digital life, but different types of malware put your computer at risk in different ways. Understanding what sets them apart can keep your business guarded.
Once created to annoy users by making small changes to their computers, like altering wallpapers, this type of malware has evolved into a malicious tool used to breach confidential data. Most of the time, viruses work by attaching themselves to .exe files in order to infect computers once the file has been opened. This can result in various issues with your computer’s operating system, at their worst, rendering your computer unusable.
To avoid these unfortunate circumstances, you should scan executable files before running them. There are plenty of antivirus software options, but we recommend choosing one that scans in real-time rather than manually.
Unlike viruses, spyware doesn’t harm your computer, but instead, targets you. Spyware attaches itself to executable files and once opened or downloaded, will install itself, often times completely unnoticed. Once running on your computer, it can track everything you type, including passwords and other confidential information. Hackers can then use this information to access your files, emails, bank accounts, or anything else you do on your computer.
But don’t panic just yet, you can protect yourself by installing anti-spyware software, sometimes included in all-purpose “anti-malware” software. Note that most reputable antivirus software also come bundled with anti-spyware solutions.
Are you redirected to a particular page every time you start your browser? Do you get pop ups when surfing the internet? If either situation sounds familiar, you’re likely dealing with adware. Also known as Potential Unwanted Programs (PUP), adware isn’t designed to steal your data, but to get you to click on fraudulent ads. Whether you click on the ad or not, adware can significantly slow down your computer since they take up valuable bandwidth. Worse still, they’re often attached with other types of malware.
This type of malware works like adware except that it doesn’t make money by tricking you into clicking on ads, but by scaring you into buying a software you don’t need. An example is a pop up ad that tells you your computer is infected with a virus and you need to buy a certain software to eliminate it. If you fall for one of these tactics and click on the ad, you’ll be redirected to a website where you can buy the fake antivirus software.
Scareware acts more like a diversion from the other malware that often comes with it. A good antivirus solution will help scan for scareware too, but you should patch your operating systems regularly just to be safe.
Ransomware has become increasingly common and hostile. It encrypts your computer files and holds them hostage until you’ve paid a fee for the decryption code. Because ransomware comes with sophisticated encryption, there aren’t many options unless you have backups of your data.
There are some tools that can protect against ransomware but we recommend that you backup your data and practice safe web browsing habits.
Similar to viruses, worms replicate themselves to widen the scope of their damage. However, worms don’t require human intervention to replicate themselves as they use security flaws to transmit from one computer to the next, making them far more dangerous than your typical virus. They often spread via email, sending emails to everyone in an infected user’s contact list, which was exactly the case with the ILOVEYOU worm that cost businesses approximately $5.5 billion worth of damage.
The easiest ways to protect your network from worms is to use a firewall to block external access to your computer network, and to be careful when clicking on unknown links in your email or unknown messages on social media.
Usually downloaded from rogue websites, Trojans create digital backdoors that allow hackers to take control of your computer without your knowledge. They can steal your personal information, your files, or cause your computer to stop working. Sometimes hackers will use your computer as a proxy to conceal their identity or to send out spam.
To avoid trojan attacks, you should never open emails or download attachments from unknown senders. If you’re skeptical, use your antivirus software to scan every file first.
In order to keep malware at bay, you need to invest in security solutions with real-time protection and apply security best practices within your office.

This is not a question often asked by anyone who has ever used a printer. Given the increasing sophistication of hackers’ capabilities, the discovery that cyber thievery can, in fact, be performed through some popular printer brands hardly comes as a surprise. One study reveals that at least 20 printer models are vulnerable to Distributed Denial-of-Service and other types of attacks. Let’s take a look at this chilling development in cybersecurity.
Which printers are prone?
Based on the study made by Ruhr University Bochum researchers, printer brands such as Hewlett Packard (HP), Brother, Dell, Samsung, and several others are prone to different types of cyber attacks. Online printers from these brands could serve as cyber criminals’ path in which to steal credentials, corrupt a printer, or leak sensitive data from printed documents obtained through a printer’s memory.
Printers serve the basic purpose of turning computer documents into paper and have never been a typical entry-point of hackers’ attacks. Government and corporate offices, business establishments, non-profit organizations, and homes own one, and when you think about the fact that most printers are linked to computer owners’ internal networks, this expansion of cyber theft to printers begin to make even more sense.
How can attacks be made?
Researchers identified security vulnerabilities that would enable hackers to corrupt common printer languages such as PostScript and PJL, which they could then use to launch Distributed Denial-of-Service attacks or reset the corrupted printer to its factory defaults, also termed as ‘protection bypass.’ Other ways in which hackers could exploit their access are through print job manipulations, which could lead to minor cases of printing corruptions or persistent printing distortions, and information disclosure, the leaking of sensitive information.
What safety measures are being developed?
The researchers who discovered the vulnerabilities developed the PRinter Exploitation Toolkit (PRET), a program designed to determine if a printing device is a likely target. This toolkit ‘connects to a device via network or USB and exploits the features of a given printer language, and is complemented by a wiki page that documents attacks made. It’s worth noting that more printer models and brands haven’t been tested due to the team’s lack of resources. But with this open-source toolkit, vulnerabilities of many brands and models may soon be identified.
Stealing information online is far from being a novelty in cyber security. But to do so through printers requires a special set of skills. It’s too soon to tell whether this form of cyber thievery is going to pose serious threats in the future, but regardless of how further studies progress, failing to implement security protocols for your network can cost you dearly.

Popcorn Time is taking ransomware to a new level of devilish trickery by asking victims to give up two of their friends for a chance to rid their own computers of the virus. In cyber security this level of diabolical blackmail represents a new and scary trend for hackers. For more information on how Popcorn Time works and what you can do to keep it off your system, keep reading.
Ransomware is nothing new. Cybersecurity miscreants have been taking advantage of online users for years by requiring payment to “unlock” a victim’s computer. What Popcorn Time does differently is give users the option to spread the virus to two other victims in the hopes that they will pay the ransom — a tactic that promises to double their money at the expense of your sense of morality (and at the expense of your friendships as well).
The Cost of Popcorn
When you inadvertently download this ransomware, you will be met with a screen that explains that your files have been hijacked/encrypted, and that to get them back you will need to pay one Bitcoin for a decryption key that they keep stored remotely. The Bitcoin fee is usually more than $700, a hefty price to pay during any season but particularly difficult for those infected during the holiday season.
Spread the “Holiday Cheer” and Hope they Bite
What makes Popcorn Time unique is the option victims have to take their cost away by allowing the ransomware to affect two of their friends for a chance to get a free decryption code. Of course, it works only if both friends pay the ransom, which leaves you looking (and feeling) like the Grinch.
Avoiding Popcorn Time this Season
The easiest way to avoid downloading ransomware is to stay off of sites that might contain questionable files. However, this is nearly impossible for modern users, and many hackers are getting good at making their files look legitimate. Limit your exposure to potential ransomware by keeping your software up-to-date and your computer protected with a security program from a reputable company (for example Norton or Symantec). If you need to learn more about how to avoid running into ransomware while you’re online, give our professional cybersecurity consultants a call. We’ll keep you away from the popcorn this season.
