TeslaCrypt is a notable threat actor that emerged with a focus on targeting computer gamers. This malicious entity was responsible for executing ransomware attacks, encrypting victims' files and demanding payment for their release. The group gained notoriety with several versions of their ransomware, including TeslaCrypt V2, V3, and V4. Each new version presented an escalated threat, requiring the cybersecurity industry to develop specific decryption tools to counteract the damage. In 2016, however, the cyber gang behind TeslaCrypt unexpectedly released a master key, allowing victims to decrypt their files without having to pay a ransom. Several organizations, including Cisco Talos, McAfee, and Kaspersky Labs, developed decryption tools based on this master key, providing alternatives to victims affected by different versions of TeslaCrypt. These tools became a crucial part of the response to the TeslaCrypt threat, helping numerous individuals and businesses recover their encrypted files. Despite the cessation of TeslaCrypt's activities, ransomware remains a significant threat in the cybersecurity landscape. A report from VirusTotal indicates that over 130 ransomware strains were detected since 2020, including familiar variants like WannaCry, CryptoWall, and others. Cybercriminals continue to use ransomware variants such as WannaCry, Cryptowall, Samas, Locky, and TeslaCrypt to attack and extort businesses. While many decryption tools exist that can unlock a variety of ransomware, some are limited to decoding files encrypted by specific strains, highlighting the ongoing challenge posed by this type of cyber threat.
