DiceCTF rank and ctftime team rank


@Frankss @Monad, we won 21 rank in the DiceCTF 2022.

Yet another win against pkucc and n03tAck QwQ.

The competition has some very interesting challenges and tricks, I'll collect them and publish on the Detroit CTF platform.

In the meanwhile, we got 27.853 ctftime scores. The coutry rank of our team is updated to 21st place.

Congratulations every member! 🎉🎉🎉

Guangdong CTF 2nd Final notes

We've participated Guangdong CTF 2nd final meeting yesterday.

The key information:

  • The final round would be in DAWD (DataCon AWD).
  • The players can't reach the inner server.
  • The players can push patch and exp to the server.
  • EDR and rootkit are not valid. But WAF is valid.

We may need to try:

  • Reverse shell to get the operation privilege in the inner server.
  • Anonymous EDR for local service.
  • Network traffic analysis and block: replace flag.
  • Store a trojan in our own patch and image file.
