Common Ransomware Infection Methods  & How to Avoid Them

How to avoid Ransomware

Ransomware is a growing problem that is affecting thousands of companies every day. In fact, according to the Kaspersky Security Bulletin, a company is hit with Ransomware every 40 seconds. And just when you think you've outsmarted Ransomware, cyber criminals develop new variants and new tactics to infect your computer, lock you out of your files and make you pay a ransom. This means that more attacks, on more companies for more money are sure to be on the way. So with a Ransomware attack imminent, how can you avoid exposure? Here are some ways that your system can be infected with a Ransomware virus: 

How can my system be infected?:

1. Email links or attachments

One of the most common ways that companies become infected with Ransomware is through viral email attachments or links. Employees should be reminded not to open emails from unknown sources or click on any suspicious links or attachments. It is also important not to forward infected emails. If there is ever a concern with an email, the best thing to do is to delete it and contact your IT security team. 

2. Vulnerabilities of your browser, operating system or software installed.

How many of us see that our computer needs to restart to complete updates and instead of hitting the "restart now" button we click "postpone"? Though keeping your systems and software up-to-date seems like a no brainer, many people avoid installing updates until it is too late. Ransomware preys on the vulnerabilities of out-of-date software. To avoid suspecting your files to an attack keep your devices as up-to-date as possible

3. Skype or any other messengers that may distribute infecting links

Programs that we use on a daily basis may open us up to the threat of Ransomware. Messaging platforms, like Skype, can distribute infected links via chat rooms. It is important that you do not open links from unknown users.

4. Downloading/running untrusted software

Files downloaded from the internet are at a higher risk of containing Ransomware viruses. Do not download and run unknown software from the internet on your computer. If you need to download something and you are unsure if it is safe, consult your IT security team.

5. Visiting untrusted sites (torrents, cracked software)

You were trying to catch the latest episode of Grey's Anatomy on an untrusted site and next thing you know you are infected with a Ransomware virus. One of the easiest ways to open yourself up to Ransomware is by torrenting files or using cracked software. You may think "I do it all the time, it won't happen to me," but from what we know about Ransomware, it is no longer a matter of IF you will get infected, but WHEN. 

Common infection approaches:

1. Any embedded executable or script files

Ransomware can infect your systems through embedding files on your systems that contain a virus. If you are in a position where you control executable or script files for your company, make sure that you know where they have come from and if they are secure before you embed them. 

2. MS office documents

Believe it or not, MS office documents can contain a ransomware virus. This goes back to not opening any suspicious or unknown attachments via your email. Ransomware viruses hidden in MS office documents are easy to accidentally download onto your computer and suspicious files should be avoided.

3. Found USBs

Studies have been conducted where USB drives have been left in areas around college campuses and over 50% were plugged into student's computers. In this case, curiosity really does kill the cat. Plugging in unknown USB drives is a leading infection approach for Ransomware. As a rule of thumb, never plug in a USB drive to your device unless you know with 100%% certainty what is contained on the drive and where it came from.

The Bottom Line

Methods of attack are always changing to adapt to new and old vulnerabilities. It is important to stay vigilant and maintain your systems integrity to the best of your ability. The best way to protect your business and yourself from the effects of Ransomware is to ensure that you have multiple copies of your data backed up in a secure location. Implementing a Disaster Recovery plan is also a good idea. Ransomware has become a lucrative business for cyber criminals and it shows no sign of dying off soon.
