Plateau Data Breach (2013)

Members of TeamBerserk accessed the user database for New Mexico-based ISP Plateau, and published more than 7,500 users' e-mail addresses and plain text passwords online (h/t The Hackers Blog). It's not clear if this is a new breach -- the statement, "All the e-mails have been dumped already" precedes the data dump -- but TeamBerserk claims to have leveraged the stolen data to access a network connected to the U.S. Army's White Sands Missile Range in southern New Mexico. "We already sorted through the military accounts in here and it lead to us a U.S. Army and AirForce Network in White Sands, Carlsbad and Roswell, New Mexico," the hackers wrote.
