Book Reviews, News Articles, and Press Releases

Ted Bridis, an AP technology writer, wrote an article entitled Hackers Holding Computer Files 'Hostage' dated Tues. May 24, 2005. The article indicates that a malware infection has occurred in which files are encrypted and held for ransom. The company Websense Inc. is cited as having analyzed it. The analysis on their website contains screenshots containing the text "PGPcoder" and indicates that payment is expected via an e-gold account. F-Secure refers to this Trojan as Gpcode (it has also been referred to as "ransomware"). An analysis by F-Secure indicates that this Trojan uses a trivially breakable encryption method. So the evidence strongly suggests that PGPcoder is not a cryptotrojan.

Joris Evers, a Staff Writer for CNET News.com, wrote an article entitled Miscreants encrypt files, hold them for ransom that is dated May 24, 2005. This article indicates that the PGPcoder trojan victimized a Websense customer two weeks prior and that the trojan targets 15 common file types. The article references "Trojan.Pgpcoder", the name that was assigned to the Trojan by Symantec. One of the types of files that are encoded is files having the extension .pgp. This could be the reason for the name "PGPcoder".
