PGPCoder
PGPCoder or GPCode is a trojan that encrypts files on the infected computer and then asks for a ransom in order to release these files, a type of behavior dubbed ransomware or cryptovirology. == Trojan == Once installed on a computer, the trojan creates two registry keys: one to ensure it is run on every system startup, and the second to monitor the progress of the trojan in the infected computer, counting the number of files that have been analyzed by the malicious code. Once it has been run, the trojan embarks on its mission, which is to encrypt, using a digital encryption key, all the files it finds on computer drives with extensions corresponding to those listed in its code. These extensions include .doc, .html, .jpg, .xls, .zip, and .rar. The blackmail is completed with the trojan dropping a text file in each directory, with instructions to the victim of what to do. An email address is supplied through which users are supposed to request for their files to be released after paying a ransom of $100–200 to an e-gold or Liberty Reserve account.
