Researchers have spotted malware that targets gamers, and threatens to trash their in-game progress unless they pay up
Once installed, Teslacrypt scans the machine's file system, and encrypts files that match a list of types, generating a random AES key for each file using OpenSSL code and using that key to scramble the data. It then encrypts the AES keys using the public key from a 2048-bit RSA key pair.
The private key, needed to decrypt the per-file keys and ultimately restore the scrambled data, is stored on the criminals' command-and-control server.
Victims have to pay a ransom of $500 in Bitcoin, or buy and hand over a $1,000 Paypal My Cash payment card, using a website hidden in the Tor network, to download their decryption key before it is destroyed.
The software nasty, dubbed Teslacrypt, works in the same way as traditional ransomware like Cryptolocker. It attempts to infect Windows PCs by exploiting a vulnerability in Adobe Flash (CVE-2015-0311) or Internet Explorer (CVE-2013-2551). A victim has to visit a booby-trapped website to get infected, although the malware backs off if it detects the presence of some antivirus packages, or if it's running in a virtual machine.
