Detects a sequence of events associated with the Astaroth banking trojan, where a script downloads a file from a raw GitHub URL, followed by the execution of an AutoIT interpreter. Astaroth is known to use GitHub to host configuration files disguised as images (steganography).
Detects the execution of "Extexport.exe", a utility that is part of the Internet Explorer browser. This utility can be abused for DLL sideloading, specifically by loading "mozcrt19.dll", "mozsqlite3.dll", or "sqlite.dll" if a folder is provided in the command line, or arbitrary DLLs if specific flags are used. This behavior is associated with malware like Astaroth and Guildma.
This rule detects PowerShell commands that attempt to store data in an Alternate Data Stream (ADS) by redirecting the output of a command executed via `cmd.exe` (comspec) into a file using the `>` operator. This technique is often used by malware, such as Astaroth, to hide malicious data within legitimate files, making it harder to detect.
