PACTF_2017: CT S(C)AN

Category: Points: 35 Description:

CHECK THE SAN. MAYBE CT SCANS ARE USEFUL TOO.

Hint:

We are a security competition, not a hospital. Consult with your healthcare professional before deciding to take any CAT scans.

Write-up

This challenge is a real troll to anyone who hasn't done SSL security before. SAN, stands for Subject Alternative Name.

Looking into the security section of the browser, you find that the SANs are all listed there, including our flag.

Therefore, the flag is pa1cdnp5ocrn977rcqy98ubvkq92o5-flag.pactf.com.
