Something is brewing up… and it smells like… a CTF!

A strange stir echoes in the shadows… a terrifying scream in the far distance…

We are thrilled (and slightly scared) to announce our second official OSINT CTF – Halloween Edition! For 30 haunting hours, your OSINT tools and investigative skills will be tested to the limit.

Get your squad ready: team of two participants will work best to survive the challenges released by the awakened pumpkin. Though if you dare, you can also ride solo…

Team registration opens on October 28th – stay sharp, stay together… and maybe you’ll make it through the night.
