The success of CryptoLocker spawned a number of unrelated and similarly named ransomware trojans working in essentially the same way, [23] [24] [25] [26] including some that refer to themselves as "CryptoLocker"—but are, according to security researchers, unrelated to the original CryptoLocker. Other instances of encryption-based ransomware that have followed have used the "CryptoLocker" name or variations bitcoin next diff change yahoo account, but are otherwise unrelated. CryptoLocker was also propagated using the Gameover ZeuS trojan and botnet.
Retrieved 24 Dec The process only encrypts data files with certain extensionsincluding Microsoft OfficeOpenDocumentand other documents, pictures, and AutoCAD files. While security software is designed to detect such threats, it bitcoin next diff change yahoo account not detect CryptoLocker at all, or only after encryption is underway or complete, particularly if a new version unknown to the protective software is distributed. In Novemberthe operators of CryptoLocker launched an online service that claimed to allow users to decrypt their files without the CryptoLocker program, and to purchase the decryption key after the deadline had expired; the process involved uploading an encrypted file to the site as a sample and waiting for the service to find a match; the site claimed that a match would be found within 24 hours.
Once found, the user could pay for the key online; if the hour deadline passed, the cost increased to 10 bitcoin. Other instances of encryption-based ransomware that have followed have used the "CryptoLocker" name or variations bitcoin next diff change yahoo account, but are otherwise unrelated. In Septemberfurther clones such as CryptoWall and TorrentLocker whose payload identifies itself as "CryptoLocker", but is named for its use of a registry key named " Bit Torrent Application"[29] began spreading in Australia; the ransomware uses infected e-mails, purportedly sent by government departments e.
