Raiders of the Lost ARP

This, friends, is the Big Kahuna of tactics we’re talking about now! When I started writing this series of posts to discuss tactics, I feared the 7th tactic from the left. Why? Because we’re talking about the diverse and expansive ATT&CK Tactic of Defense Evasion. This brute contains a whopping 43 techniques and 155 sub-techniques. It is almost as if our adversaries really want to avoid detection or prevention and need options! Well, as this is so massive, we’re going to take a more holistic approach to this entry.

It has been a little bit since we dove into the MITRE ATT&CK Tactics. When we left off with Persistence, we talked about how attackers maintain their leverage by opening as many ways in as possible. All use multiple vectors to cover their bases, but it is really hard to stay a step ahead and have impact if they don’t get heightened permissions. History shows that attackers who can either disrupt, discredit, or even hijack the command structure can cause a whole new level of pain. The pinnacle of many adversaries’ tactics is to be able to issue commands as if they were a highly placed commander within their target organization. It not only grants an amplifying effect, but can also hide their activity as they exploit trust. So let’s take a look at ATT&CK’s Privilege Escalation tactic and what it means to the attacker & defender.
