AgentTesla From RTF Exploitation to .NET Tradecraft
When adversaries buy and deploy threats like AgentTesla you often see this functional and entertaining chain of older exploitation activity with some .NET framework tradecraft youβd expect from some modern implants. In this post Iβll walk through analyzingβ¦
Guess I will get to see how my theory on this will play out in real life now

Microsoft blocks VBA macros originating from Internet based on MOTW flag.
I'm now sharing a tool presenting risk for MOTW bypasses, which will play crucial role in evading MS default setting and smuggle macros back in.
Threat Actors already do that.
