Detection evasion in CLR and tips on how to detect such attacks

In terms of costs, the age-old battle that pits attacker versus defender has become very one sided in recent years. Almost all modern attacks and ethical offensive exercises use Mimikatz, SharpHound, SeatBelt, Rubeus, GhostPack and other toolsets available to the community. This so-called...
