ColdStealer is a relatively new malicious program that was discovered in 2022. Like many other stealers its main purpose is to steal credentials and information from web browsers, in addition to stealing cryptocurrency wallets, FTP credentials, various files and information about the system such as OS version, system language, processor type and clipboard data. When the infostealer collects information that will be stolen, it saves the information in the ZIP form instead of files in the memory. Doing so will allow the malware to bypass detection as there are no traces of files and execution. The only known method of delivering stolen information to cybercriminals is by sending a ZIP archive to the hardcoded command and control (C2) server.
