![]() What separates GOZ from regular ZBOT malware is its P2P capability. It uses a configuration file downloaded from a specified URL. GOZ, being an offshoot of ZBOT malware, steals credentials used in banking and finance-related sites. Meanwhile, GOZ variants cropped up in 2013. Therefore, it is important to stop the CryptoLocker infection chain before it executes. This is because once files are encrypted, almost all anti-malware tools are only able to remove the CryptoLocker variant from the system, leaving encrypted files unusable. Moreover, CryptoLocker infections puts infected computers at an elevated risk of being rendered unusable. However, paying doesn’t guarantee access to the infected system. UK and Canada had their share of infections at 11% and 6%, respectively.Īs with any ransomware, once the system is infected, the user is coerced to pay (a ransom) through online payment methods to regain computer usability. In our October 2013 report, we have observed over a 30-day period that 64% of detected global infections were seen in the US. Since the discovery of CryptoLocker, the number of its victims has exponentially grown. If its peers are no longer existing, it uses its domain generation algorithm (DGA) to connect to a randomly-generated C&C, where it gets its configuration file. GOZ, also known as P2PZeus/GameOver, is a ZBOT variant that uses its peer-to-peer (P2P) network to download its configuration file. Trend Micro Tools for GOZ and CryptoLocker Malware This may be a tactic to ensure that the victim pays the ransom, as there is no other way to decrypt the files but with a key that the cybercriminals responsible can only provide. ![]() ![]() ![]() CryptoLocker is a ransomware that not only locks the system it affects, but also encrypts certain files found in the system's hard drive. GOZ and CryptoLocker are two of the most notorious malware that we have seen as of late. ![]()
