When HENkaku was first released, we posed to the community the KOTH challenge to get more hackers interested in the Vita. This week, two individuals have separately completed the challenge and are the new kings of Vita hacking! Mike H. and st4rk both proved that they have the final encryption key, showing that they solved the kernel ROP chain. I highly recommend reading their respective posts as they give some great insight into how hacking works. I also know of a third group who might have also completed the challenge but wishes to keep quiet for now. Congratuations to them too!
