Your question is Security Challenges on Registration Portal. Take a moment with it on the right.

Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).

You need to log in / sign up to chat or submit.

Problem

Solve a set of about 12 CTF-style security challenges on a registration/login portal within 6-7 hours, covering malware analysis, crypto analysis, reverse engineering, a web OTP challenge, AWS security (dev/ops) and two forensics tasks.

Asked in the Take-home CTF challenge portal stage. Given after the hiring manager technical interview; the challenges may differ by team.

Submit the recovered flags or answers with concise evidence, commands, assumptions, and explanations for each challenge. Work only within the supplied environment and document any tooling, failed approaches, or uncertainty.
