I dived into iOS kernel exploitation recently and have written a kernel exploit for chain 3 of @i41nbeer blog post series from last August. Check out the post at the @secfaultsec blog :) secfault-security.com/blog/chain3.ht… Feedback highly appreciated!

Today is the last day to apply for a FREE pentest on your application that helps fight COVID-19! Since the closure of schools requires good tools for educational learning, we would love to see last minute submissions from this field.

@teh_gerg @koehntopp Ah indeed, that’s another important point, especially in complex high risk projects. Particularly meaningful with all this microservice salad and abstraction layers.

@janmuenther @koehntopp Well, it also provides an end-to-end view of a product at a certain stage, which can help identifying issues emerging from the interplay of its components. But that's another focus than the classical pentest before release idea.

@koehntopp @teh_gerg to be fair though, I still use in pen testing - as a wake up call for teams in denial, and as a verification of assumptions in a very dedicated, targeted fashion as @teh_gerg outlined. Ideally, you consider pen test targets when you conceptualize your mitigations.
