Frontrunning hacks is an up-and-coming application of MEV in security and, more specifically, hack prevention. In an industry that is hunted by billions of dollars in hacked funds, users need a system that they can safely use to manage their wealth, so more and more creative ideas are being suggested as a solution. Frontrunning hacks started organically, as MEV searchers generally front-run anything valuable via generalized frontrunning bots. With millions of funds secured and returned via these generalized frontrunning bots, services that offer specifically this benefit to protocols have started to appear. All of these are bound to become irrelevant, as the moment they become ubiquitous, hackers will choose to use private builders that will directly produce blocks that include malicious transactions. Even if block builders start cooperating with said services, we will see the creation of "back mem pools," builders that cater to hackers' needs and will include malicious transactions, no questions asked. These builders will be protocol-compliant, and the community can do nothing about it. In this talk, we will go through the current landscape, explore why these solutions become notorious (and how they work), and then describe the end-state and these black mem pools.
