I would love to take a look at these underground hacker places to see what goes on and what to watch our for… I’m guessing it’s all dark web stuff though. Are any of these forums available on the clear net?
Based on the user rank in the BleepingComputer article's screenshot ("kilobyte") it looks forum.exploit.in. Anyone can buy a membership for ~$100 in BTC. I've read some of these places and honestly it's pretty boring. It's basically just a marketplace for software to steal money from people in first world countries (stealers, n-day exploits, crypters, AV scanning services, phishing services) and a bunch of supporting services like residential proxies, hacked RDPs, SSN lookups, and "drop" bank/crypto exchange accounts.
There are others that are public: antichat, wwh-club, bhf. I'm not on it but I think the most "elite" forum is called Mazafaka and requires a substantial deposit and a recommendation from existing members.
Exploit.in is more technical than most of these forums but a lot of these people are not really very technically skilled they just have a very good understanding of how anti fraud systems work and how to circumvent them.
