Wolv CTF 2024

Wolphv I Reconaissance [100 pts]

A new ransomware group you may have heard about has emerged: WOLPHV

There’s already been reports of their presence in articles and posts.

NOTE: Wolphv’s twitter/X account and https://wolphv.chal.wolvsec.org/ are out of scope for all these challenges. Any flags found from these are not a part of these challenges
