The Cryptolocker 1.0.0 Ransomware is a Turkish variant of CryptoLocker, a 2013-dated Trojan that can encrypt your files. Any symptoms that are visible launch after this Trojan has locked your files, potentially making them impossible to recover. Use anti-malware programs for safely removing the Cryptolocker 1.0.0 Ransomware either before or after it encrypts your PC's data and backups, if required, for reversing any damages.

Presented with a Choice in Poison Pills

The Cryptolocker family is exhibiting an unusually long lifespan for threatening software, possibly thanks to its still-unbreakable encryption features. A Turkish threat actor referred to as 'Alp' is developing a new version of this Trojan with the improperly-numbered Cryptolocker 1.0.0 Ransomware, also set to attack Turkey-based victims. Like old versions of the same program, the Cryptolocker 1.0.0 Ransomware uses RSA encryption to hold what's on your PC hostage.

As current samples are only functional partially, the Cryptolocker 1.0.0 Ransomware project seems still to be in the midst of its development and, hopefully, may never be finished and released into the wild. However, like old CryptoLocker variants, the Cryptolocker 1.0.0 Ransomware can scan for files on your PC, isolate them based on either their formats or their locations, and encipher them with an RSA-based algorithm that blocks them from opening.

The Cryptolocker 1.0.0 Ransomware's most evident symptom is the pop-up message it launches after taking your data hostage. The Turkish-language ransoming message offers a choice between a 'red pill' button for deleting your files and a 'blue pill' button for decryption after negotiating with the threat actor over e-mail. Including themes from media, like the Matrix cinematic universe is one of the ways that Trojan authors try to distinguish their 'products' from those of their competitors.

Preventing Your PC from Making a Pill-Popping Proposition

Despite the version number that Alp is attaching to his project, the Cryptolocker 1.0.0 Ransomware isn't the first, full-fledged version of Cryptolocker. Variants of the family are verifiable throughout the past few years, with many of them circulating throughout e-mail attachments. Malware experts have yet to see the Cryptolocker 1.0.0 Ransomware playing a part in any live attacks, but its filenames are indicative of it disguising itself as some form of Adobe PDF content potentially. These 'documents' may pretend to be department messages or communications from a third-party, such as a tax consultant or delivery company.

Limited decryption tools are available for free download to counteract the payloads of old versions of Cryptolocker, but no similar solutions have yet appeared for the Cryptolocker 1.0.0 Ransomware. Since decryption never is certain, malware researchers advise backing up your hard drive and ignoring ransom demands from Alp or other threat actors conducting attacks of a similar nature. Most PC users benefiting from active anti-malware monitoring should be able to delete the Cryptolocker 1.0.0 Ransomware proactively.

The Cryptolocker 1.0.0 Ransomware offers you a choice between two equally poor options. The small amount of time required to backup your files always is worth it, in comparison to the often massive losses of data that Trojans of this description can levy.
