Thanks to osmocombb and the whole osmocom GSM network stack components I was able to build my own GSM phone for a #35c3ctf challenge. Any similarity with previous commercial phones is a pure coincidence. If you want to hack this thing, check out newphonewhodis and identitytheft.


It is our first international CTF participation and we stood 19th among 520 teams in the #junior35c3ctf. Thanks to @EatSleepPwnRpt for organizing such an awesome CTF. #35C3CTF

I published the source code and (commented) example exploits for my #35C3CTF macOS browser exploitation challenges: github.com/saelo/35c3ctf congrats to @qwertyoruiopz and @i41nbeer for solving all parts (and winning the CTF)! :) #35c3

This year at #35C3CTF you can write a full macOS browser exploit (renderer + sandbox escape). Check out the "WebKid" and "Pillow" challenge here: 35c3ctf.ccc.ac/challenges/ :) big thanks to @_niklasb for the amazing infrastructure setup! #35C3

Ok, this is awesome, a bug I found and disclosed is featured in the #35c3ctf 0day challenge with players looking to bypass the fix. Looks like 2 teams have found new bugs... this is why sharing your findings is so cool :) 35c3ctf.ccc.ac/challenges/


Hi, @CCCAC! I believe the certificate for archive.aachen.ccc.de/35c3ctf.ccc.ac/ has expired. It's soon @ccc and I guess I'm not the only one interested in stats from #35c3ctf... :)


On #35C3CTF I made a little challenge dubbed 0pack, now the code is open source, redesigned as general purpose tool: github.com/Luis-Hebendanz… HTML slides can be found here: luis-hebendanz.github.io/0pack/

#35c3ctf github.com/vngkv123/CTF/t… Dirty exploit code for krautflare challenge :( Understanding v8's optimization routines are quite hard for me, but it is very interesting challenge ! Thanks for 35c3ctf !


I did a writeup of the #35c3ctf challenge Keybase. Didn’t solve it during the CTF but had a lot of fun doing it afterwards! blog.ttdennis.com/2019/01/13/wri… #35c3


If you liked my logrotate #35c3ctf challenge, check out this bug in tmpreaper: debian.org/security/2019/…. The vulnerable pattern was: rename("/tmp/foo", "/tmp/foo/X") Though I didn't write a full exploit I believe this should give you a root shell.


ddaa.tw/35c3ctf_2018_z… #35c3ctf logrotate write up (Chinese only, sorry)


I met some guys that attended the #35c3ctf, they told me there was an obike challenge. Is the app related to this?


Awesome! Finally my #35c3ctf express-yourself challenge got solved :) And a very cool unintended bonus solution is in there as well!

Here is my writeup on how I solved the express-yourself challenge from the #35C3 CTF. github.com/r0nen/ctf/tree…



Cool, that means all 5 0day challenges from #35C3CTF got solved eventually :)
