Saint Bot is a downloader malware that has progressively grown in popularity since its discovery in early 2021. It delivers stealers to infected systems, although it could be used to deliver any malware. Taurus, a malware program designed to collect passwords, browser history, cookies, and data from auto-fill forms, is one of the information stealers that Saint Bot has been dropping. Saint Bot has a number of obfuscation and anti-analysis characteristics that enable it to evade malware detection systems and tools.
Saint Bot is distributed using phishing emails that contain ZIP attachments that contain LNK files. When the LNK file is viewed, it refers to a download URL, where it downloads and runs an initial PowerShell loader in the %TEMP% folder. The loader then downloads and runs two EXE files, the first one is a batch script that tries to deactivate Windows Defender, and the second is Saint Bot.
