Ransomware is particularly damaging malware, where attackers either disable systems or encrypt your data and demand money to give access back to you. It's a huge problem, and this graphic is a quick guide to those attacks, how they work, and how you can protect yourself from them.
It's especially important to pay attention to the whole "how you can protect yourself" aspect, because in many cases paying off attackers doesn't work, and instead -- like in any hostage situation -- giving the attackers what they want only proves you're willing to cave and boosts their resolve (and their demands.)
Instead, prevention is key, and that starts with education, not to mention strong, updated antimalware protection for all of your devices. The graphic (although it's not too much of a graphic, to be fair) explains further below, and you can hit the link below to read the full accompanying article.
