CryptoLocker, that infamous ransomware that enters your computer, locks it up, and then demands a ransom to unlock it keeps morphing into newer and nastier versions. The newest, according to CyberheistNews, is being called CryptoWall and has a new process to attack the unwary. Unlike previous versions of ransomware, CyrptoWall does not need the victim to open a piece of email that installs the malicious software. Instead it takes advantage of a vulnerability in Java so that when a user goes to some website, is attracted to some advertisement (Disney has been used as well as Facebook) and clicks on it for more information, the software is loaded to your computer, and your machine is locked up.
While CryptoLocker has a new face, the entire issue can be avoided with the same old time tested warnings…do not open suspicious emails, and do not click on advertisements. If you do, you are just asking for trouble.
