This year, I managed to win TISC again 🎉

Over 11 days, I worked through all 12 challenges and managed to complete the full set – the only player to do so. I opted for the Web/Cloud track since the Reversing track didn’t have a Web3 challenge unlike last year 😆

The challenges were, as usual, creatively designed and fun to play. Huge thanks to the organizers for another great event. I personally felt that the median difficulty was a little lower than last year, though Level 11 definitely made up for it, taking almost 5 days to fully solve.

Here are my write-ups for each level.

• Level 1: Target Reference Point (OSINT)
• Level 2: The Spectrecular Bot (LLM)
• Level 3: Rotary Precision (Misc)
• Level 4: Spectre Memory (LLM)
• Level 5: SYNTRA (Rev)
• Level 6: Passkey (Web)
• Level 7: Santa ClAWS (Web, Cloud)
• Level 8: VirusVault (Web)
• Level 9: HWisntThatHardv2 (Rev, Pwn)
• Level 10: Countle Secured Storage (Web, Rev)
• Level 11: Ash Twin Project (Web, Pwn)
• Level 12: SpectreChrome (Pwn)
