For Windows users, tips for fighting ransomware attacks

Ransomware.

This is a horrifying word for many computer users, especially given the almost daily headlines about the affected companies. I wonder why this continues to happen to users and businesses, big and small.

But there are many things you can do to protect yourself and your business.

Be careful what you click

Ransomware that affects individuals most often occurs after someone clicks on something they shouldn’t do, such as phishing emails or web pages that install malicious files. In business environments, attacks often come from attackers who use either brute force or collected credentials to track open remote access protocols. Once inside the network, you can disable backups and wait until the best time to attack.

Ransomware is not new.Its history Dating back to 1989.. At that time, the lure was a floppy disk with the virus installed and demanded money to get the computer information back on the third day. recently, Used for colonial pipeline, East Coast gas supply pipeline company.That attack Led to the execution of gasBad publicity (and reported multi-million dollar payments) for closed gas stations, angry drivers, and pipeline companies. This was an example of what ransomware can do for businesses.

Backup, backup, backup

I co-moderate a Facebook group on security and ransomware topics. Often, when users come to us to ask how to recover from a ransomware attack, our only recommendation is to ask if they have a proper backup. That means something that runs on a regular basis and is stored on an external hard drive that is “air-gap” from your computer. If the drive where the backup is stored can be accessed, an attacker can also access it. Therefore, rotate the backup media and make sure that you always have a copy that is not offline and connected to your system.
