VEP: Handling This Patch's Meta Changes

We may be about to enter the Healer meta in Cyber War for Season 3, what does that mean for you?

The Meta Change


Google caught an 0day this week, and Microsoft issued an out of band patch. Kaspersky has been catching and killing 0day as well recently, at a much higher pace than you would expect, something over one a month. If that doesn't surprise you, then it's probably because you're accustomed to seeing defensive companies catch only implants or lateral movement and then helplessly shrugging their shoulders when asked how the hackers got in.

But we're about to enter a healer-meta. In Overwatch, that is when the value of defensive abilities overwhelms the damage you can do over time. So your offense is forced into one of two options:

  • High Burst Damage Heroes (such as snipers, Pharah, ultimate-economy playstyles, etc.)
  • Diving healers
In Cyberwar what this means is that when effective defensive instrumentation gets widely deployed (and used) attackers are forced to do one of three things:
  • Use worms and other automated techniques that execute your mission faster than any possible response (burst damage)
  • Operate at layers that are not instrumented (aka, lower into firmware, higher into app-level attacks)
  • Modify the security layers themselves (aka, you dive the healer by injecting into the AV and filtering what it sends)

VEP

There were two arguments around what you should do in a VEP in a Healer Meta at the Carnegie conference. One, was that since you knew bugs were going to get caught, you should make sure you killed them as soon as possible after use (which reduces threat to yourself from your own bugs). The other was that you were going to need a huge stockpile of bugs and that you should stick to only killing bugs that you knew for sure HAD gotten caught, and only if your attribution was already broken by your adversary.

These are very different approaches and have vastly different strategic needs.

Of course, the third take is to avoid the problem of 0day getting caught by focusing on the basics of countering the meta as outlined above. But a nation state can (and will) also use other arms to restrict the spread of defensive technology or erode its effectiveness (i.e. by attacking defensive technology supply chains, using export control to create deliminations between HAVES and HAVE NOTS, etc.).
