What is SILENTTRINITY and why is it notable for C2 operations?

SILENTTRINITY is an open-source C2 framework implemented in C# that uses the IronPython engine to execute Python payloads directly from memory, making it stealthy and difficult to detect with traditional file-based signatures. This technique of loading code without writing to disk is similar to methods analyzed in AtomBombing Exploitation Analysis, where code injection occurs entirely in memory.
