More Updates

This announcement affects the following problems: Denial of Searching Attack, Part Two: Crash Collision! Who Hacked Me?

Due to some bugs in the system that handles static files, problems thought to be fixed weren’t. They should now all be good.

Who Hacked Me? and Denial of Service Attack Part Two unfortunately had accidental bypasses that solved the challenges in an unintended manner. Although this is obviously not an ideal scenario, we’ve been forced to revoke the solves that teams had for those problems. If those solves were legitimate, redoing them shouldn’t require that much work on the contestants’ parts. Again, we sincerely apologize for all of the issues we’ve experienced. Please direct any concerns you have to us on Discord. Thank you.

We’d also like to commend team “Using the Laptops CTF” for bringing some of these issues to our attention at cost to themselves: that’s the spirit we hope everyone has in PACTF!

Legendary Weapons Issue

3 months, 1 week ago
This announcement affects the following problems: Legendary Weapons

There was an issue with the “Legendary Weapons” problem that had made it unsolvable. All teams that tried certain flags should try them again, as now the problem should accept the correct flag (before, it would reject any submission). We are deeply sorry for this inconvenience.

Issue With Graders

3 months, 1 week ago

There was an unfortunate issue with the grader files for some of the problems that made them simply accept any answer as correct. This problem has been fixed for now. Unfortunately, this means that any team that incorrectly solved the problem previously has had those points removed, and will need to attempt them again. We are deeply sorry for this inconvenience.
