win.noodlerat

Win.NOODLERAT is a malware variant that functions as a backdoor into infected systems, allowing unauthorized access and control. It is part of the Noodle RAT family, which has two versions: one for Windows (Win.NOODLERAT) and another for Linux (Linux.NOODLERAT). This malicious software infiltrates systems through suspicious downloads, emails, or websites, often unbeknownst to the user. Once inside, it can steal personal information, disrupt operations, or hold data hostage for ransom. Interestingly, Win.NOODLERAT shares similarities with another known malware, Gh0st RAT. They use the same plugins, and Win.NOODLERAT implements an encryption algorithm similar to those used by some variants of Gh0st RAT, such as Gh0stCringe, HiddenGh0st, and Gh0stTimes. However, upon further analysis, cybersecurity firm Trend Micro found that the rest of the code between Win.NOODLERAT and Gh0st RAT does not appear similar, leading them to conclude that while the plugins were reused, the backdoors themselves are fundamentally different. In a detailed blog post, Trend Micro's threat intelligence team provided a technical analysis of both Noodle RAT versions, including their initialization, communication with command and control (C2) servers, control mechanisms once installed, and descriptions of the C2 server features. This analysis offers valuable insights into these threats, enabling better understanding and development of countermeasures against these malware types.
