How to Protect Yourself from Ransomware

October is Security Month, so here are a few tips on how to keep your network and data safe from malicious ransomware!

What is Ransomware?

Ransomware is a software based attack of a computer network that takes a company’s sensitive data as ransom in order to blackmail them. Ransomware is most typically delivered via an exploit kit, which take advantage of outdated software patches, or phishing attacks, which act as a reliable source to try and trick users into giving them information. There are a variety of different ways a network can be exposed to ransomware, such as through unsecured sites or untrustworthy email attachments.

A ransomware attack can bring a variety of different issues to a computer network. This includes temporary or permanent loss of data, shut off access from computer systems and applications, disruption of company operations, loss of capital, and even loss of positive reputation. Instead of leaving your company’s network up to chance, here are a few things every user can do to protect their sensitive data from a malicious software attack.

Police Your Email

One of the most popular ways to get ransomware onto a vulnerable network is through phony emails, as they can easily be manipulated to look more authentic. Before opening any email, there are a few things you’ll want to check. First, make sure you know the sender of the email as a reliable source. Often times hackers will copy the format of a more reputable company’s email in order to pose as them, so make sure you check that the sender is verified. If there is an attached link, make sure the attachment is safe before downloading it. If an email is threatening to close your accounts or cancel your cards, do not provide them with the information they are asking for.

Keep Your Computer Updated

The best way to make sure your network is secured is by staying vigilant with your system and software updates. Developers will often put out new updates with patches, which will ‘cover up’ vulnerabilities that a hacker can exploit. Check for updates constantly, and allow your most trusted software to do automatic updates if possible. Make sure to check up on your antivirus too, as it’s your frontline defense to a malicious attack.

Back Up Your Data

In the case that your data is compromised, you’re going to want to give yourself some kind of backup. Make sure that your most critical is being backed up in a location other than your network, preferably off-site. Note that files that have been saved on a USB drive or a different location in your network can still be vulnerable to attacks. With your network backed up, you’ll easily be able to recover any data that you may have lost through a ransomware attack.
