The most recent hack, affecting an invite-only cyber crime forum known as Maza, took place this week, with security firm Intel 471 revealing that its users were redirected to a breach notification page upon signing in. This was posted alongside a 35-page PDF file allegedly containing a portion of forum user data, comprising more than 3,000 rows of usernames, partially obfuscated password hashes, email addresses, and other contact details. The Maza hack follows attacks against Verified in January, Crdclub in February, and Exploit last week - all well-known dark web forums. This is in addition to a recent fifth attack against Hydra, a dark web marketplace known for the trade of illegal drugs and other criminal services, according to reports from Russian media.
