Full house!! More than 85 people joined us last Tuesday for a fantastic edition of our annual CTF101! 💪 Thanks for joining, see you soon at one of our upcoming CTF participations 🙂 A big thanks to the challenge creators/presenters and everyone involved in the organization!
Two days ago we had a very successful second edition of our annual CTF101 💪 More than 75 participants learned about CTFing and caught their first few flags in the crypto, OSINT and web categories. See you all soon at one of our CTF participations 🙂
We had a very nice PWN101 last night and did some great hacking! 🧑💻 All challenges, slides and (soon) the recording are available on pwn101.stellarvector.be so you can continue hacking at home! 💪 Thanks to the presenters (@IgnoulJoris & Robin Jadoul) and our present members!
Last weekend, our participation in GlacierCTF resulted in a 12th place 🥳 Thanks to all our members that joined!
Today, we are participating in both #HITCONCTF2022 and GlacierCTF. The latter is specifically targeting beginners, creating the perfect opportunity for interested beginners to join!
We had a great starting event ("CTF 101") yesterday evening! Around 70 people joined us for a slice of pizza, some drinks and of course, (an intro to) hacking.
Some technical details and discussions of the new WPA3 standard mathyvanhoef.com/2018/03/wpa3-t… Overall WPA3 increases security! Though there is still room for more improvements.
Key Reinstallation Attacks: Breaking WPA2 by forcing nonce reuse krackattacks.com and see the paper at papers.mathyvanhoef.com/ccs2017.pdf
Slides of my #33c3 talk "Predicting and Abusing WPA2/802.11 Group Keys" slideshare.net/vanhoefm/predi… PDF slides at papers.mathyvanhoef.com/33c3-broadkey-…
Two papers accepted at USENIX Security 2016! One on WiFi / WPA2 security, other with @tomvangoethem on side-channels
“Request and Conquer”-paper with @vanhoefm was accepted at @USENIXSecurity!
