Chances are, whether you watch the news or simply get your news from your Facebook feed, you have heard of ransomware. Ransomware programs are incredibly scary, as your files and programs can be taken hostage unless you pay a certain amount to an anonymous source. What exactly is ransomware and what are the worst types out there right now?
What is Ransomware?
Ransomware programs are a type of malware. They work by encrypting files on your computer and then locking them to you. In order to unlock those files, you need to send money (typically paid via bitcoin) to a certain location. Sometimes ransomware will only encrypt some of your files and take over part of your computer, but other times it will encrypt the entire hard drive and leave you with a useless paperweight.
One of the worst ransomware programs is called Locky Ransomware, first discovered in February 2016. This ransomware is typically sent through email attachments that will sound legitimate (titled Invoice or something similar). Once the user opens the attachment, it will ask the user to allow the macros to run. Once the user clicks yes, all of the files from Locky are downloaded and the system is affected.
Another type of dangerous ransomware program is called Cerber. This is more powerful than Locky because it can be downloaded by just about anyone, customized for their purposes, and then spread out. This ransomware is spread through two different methods, the first being the same as Locky. The second is sending a link to unsubscribe from a mailing list which leads you to the attachment and then your system being compromised.
We saved the worst for last, as CryptoWall ransomware is the worst of the bunch. This spreads through vulnerabilities in the Java plugin and advertisements that run on popular websites like Facebook and Disney. The ransomware enters the computer almost silently and scans the hard drive for files. Once it determines what files to lock, it will begin to make itself known.
