## AI overview

This technical article documents work on the first F00D exploit for the PlayStation Vita, including a memory-corruption vulnerability in a service and the role of F00D's private memory and cryptographic hardware accelerator.

## Source excerpt

This article was originally written 2019-01-11 and published on 2019-07-29 for the third anniversary of HENkaku, the first Vita jailbreak. It documents the work we did in early 2017, just days after the seminal "octopus" exploit. Although the work is dated and does not open any new doors, the technical contents might be interesting for a particular audience. The original intention was to post this after someone else independently discovers the same vulnerability. There were many overt hints on the HENkaku wiki that the 0x50002 service was buggy but I underestimated the interest (or skills) that people would have in hacking an exotic processor that ultimately does nothing for people who just want to run homebrews or play pirated games.
