Didn’t realise this CTF was on until the last few hours but here’s one challenge I got done. Snab?

Second writeup from CSAW, a Software Engineering challenge more than crypto in my opinion!

Huge year again for CSAW which has some of the longest history of any CTF and always puts a good show on with creative challenges at all levels. I plan to writeup two challenges that got the least solves of the ones I solved. This is the first.

Fun OSINT challenge that I solved in the last hour of the CTF today. In contrast to many OSINT challenges in CTFs I’ve done lately where the flag consists of a bunch of sub fields that I spend a lot of time with wrong guesses, this challenge wanted just one thing. An email address. How hard could that be?

Great CTF with a lot of interesting challenges and props to them for running it mid-week. Lots of people have work on mid week but at night after work this gave me some fun diversion. This was a web challenge that seemed a bit tricky so only attracted a few solves. I’ll go over how I did below.
