Did you know that viruses, ransomware, spyware, and trojans are all categorized as types of malware? Having been around for decades, these cyber threats have grown both in number and intensity. Needless to say, it pays to know how each of them works as well as how to protect your business.

Viruses

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.

Spyware

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.

Adware

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.

Some adware programs come packaged with legitimate software and trick you into accepting their terms of use, which make them especially difficult to remove. To eradicate adware, you’ll need a solution with specialized adware removal protocols.

Scareware

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

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.

Worms

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.

Trojans

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. If you have any questions or concerns, or simply need advice on how to strengthen your business’s security, just give us a call and we’ll be happy to help.

hackerscybersecurity-170px-03Have you had to deal with security issues in the past year? Brace yourself, as there are more to come. For this reason, security experts have become indispensable members of society, who guard tech-dependent individuals and businesses against malicious attacks that pose threats to their privacy and livelihood. As you ring in the new year, make sure you’re well armed against the following predicted cyber-crimes.

Increased threats on cloud technology

Cloud service has numerous benefits to businesses. They make data storage, collaboration, and processing more efficient; they enable employees to work faster; and they help operations flow smoother. Cloud technology’s popularity is expected to rise well into the next few years, but as demand increases, so does the dangers presented by cyber attackers.

Ransomware will be more complex

Ransomware incapacitates computer systems by locking down files and preventing access for ransom. In its 2016 Threat Predictions report, security software company McAfee predicts a peak in ransomware attacks next year. Although they also predict it to recede by mid-year, damages to vulnerable cloud-dependent infrastructures can be great and costly. Most alarming in the prediction, however, is that in the coming year ransomware attacks will be more complex due to new elements.

Ransomworms, which use advanced victimization techniques to mine further data within an already compromised network, are expected to put an even crueler spin to an already formidable malware. Doxing, on the other hand, affects avenues such as social media and any place where sensitive, easily identifiable information can be extracted to serve the ultimate purpose of extorting money. Yet another wicked ransomware to watch out for is Backup Deletion, which destroys the very mechanism that can otherwise help you recover from a compromised system or files: your backup data.

More threats to IoT (Internet of Things)-enabled devices

It is also predicted that 2017 will see attacks made on IoT-powered devices, which will make life harder for those who depend on technology that makes life easier. It targets medical devices and Electronic Medical Records, “connected cars”, basic domestic tools, and tech-driven wearables, such as smartwatches and fitness trackers. The danger posed by this intrusion is fully capable of corrupting information stored in your devices.

Advanced cyber espionage

Cyber espionage is by no means a novelty. In 2017, it’s expected to hold sway in cyber-threat prevention measures as it becomes even more complex. It encompasses all sectors of society, including individuals, private organizations, government institutions, and entire countries. Perpetrators will have the means to bypass networks by attacking firewalls and wreak havoc in their victims’ network. Fret not, for there will be measures in place to detect this threat also in the coming year.

Hackers are one of the most cunning criminals to have ever existed. While the cyber-police and the defenses they put up are no slouches, threats to security systems can still make technology-dependent individuals and businesses quiver. Although damaged networks can be repaired, compromised privacy restored, and stolen data returned, the amount of damage that hackers can cause might be irreparable and/or result in a significant dent in your IT infrastructure and budget. The value of a network security system makes itself known when you least expect it, which is why security should be a top priority.
