CryptoWall, is a sneaky ransomware Trojan that burst onto the scene as a cousin of CryptoLocker. Its hobby? Swiping data and making you pay to get it back.
CryptoWall spreads its mischief mostly through phishing and spam campaigns that lure folks into clicking malicious links or downloading nasty email attachments. It even hitchhikes on website ads to boost its reach! Once it strikes, it encrypts all data on the victim’s PC and any others connected to it via the same network.
The catch? Pay up in bitcoins for the decryption key to unlock your precious files. With four versions already, CryptoWall isn’t done yet—so stay alert and protect your digital world!
