Cryptolocker Wants Your Money!
You may have read about the Cryptolocker malware, a new ransomware Trojan that encrypts your files and demands money to return them.
In the past, we have witnessed similar malware like the famous GPCode that used RSA keys for encryption. Back in 2008, we cracked the 660 bit RSA key used by GPCode and provided the victims with a method to decrypt and recover their data. Later, the GPCode authors upgraded the RSA key to 1024 bits, putting it perhaps only in the realm of NSA’s cracking power.
