Does anybody have anymore information about the possible upcoming DDoS attack (called Op USA) from the Mauritania HaCker Team besides the information listed below on May 7th? Any suggestions on preventing or deflecting this type of attack and exactly what US companies or industries they might be targeting? http://pastebin.com/6biF9ST3 After Op Israel , Mauritania Attacker founder of Mauritania HaCker Team , Ex Member in ZHC , Founder of Teamr00t and AnonGhost Team has decided to Launch another Op wich he called "Op Usa" also same day like Op Israel but the next month 07/05/2013.
