Black Hat Europe 2017: NCC Group’s pre-event challenges part one

Black Hat Europe 2017 is less than one week away, so we thought it would be fun to release a couple of security challenges to coincide with the event build up.

NCC Group is a platinum sponsor of the annual conference for the second consecutive year and our very own David Wong is presenting his talk ‘Fed up of getting shattered and log jammed? A new generation of crypto is coming’ in the ICC Capital Suite at 3:15pm on Thursday 7 December.

A new generation of crypto is coming The SHA-3 standard came out in 2015 including the new hash function SHA-3 itself (based on a sponge construction) as well as SHAKE, a new kind of hash function called XOF. This talk will first go over these two modern algorithms, and will then introduce the other standardized functions derived from SHA-3 (KMAC, TupleHash, ParallelHash) and the more mature, modern and faster hash functions based on SHA-3: KangarooTwelve and MarsupilamiFourteen.

We’ll be sharing the final two challenges in the coming days, so keep an eye on our blog or social media platforms to stay in the know. If you complete each one and are lucky enough to be attending Black Hat, you can come and see us on our stand to claim some warez. Otherwise, submit all of your answers or flags to response@nccgroup.trust by Friday 8 December to be added to the cooking pot.

For more involved exercises you can take a look at our ninja challenge here: https://areyouan.ncc.ninja/
