Maza is an elite, invite-only Russian-language cybercrime forum known to be operational as early as 2003. The intrusion is said to have occurred on March 3, with information about the forum members including usernames, email addresses, and hashed passwords publicly disclosed on a breach notification page. The announcement was accompanied by a PDF file allegedly containing a portion of forum user data. The development comes close on the heels of successful breaches of other forums, including that of Verified, Crdclub, and Exploit.
