Suspicious Unsigned Dbghelp/Dbgcore DLL Loaded (via image_load)

This rule detects the load of dbghelp/dbgcore DLL (used to make memory dumps) by anomalous processes. Tools like ProcessHacker and some adversary tradecract use MiniDumpWriteDump API found in dbghelp.dll or dbgcore.dll. As an example, SilentTrynity C2 Framework has a module that abuses this API to dump the contents of Lsass.exe and transfer it over the network back to the attacker's machine.
