MANILA/BOSTON (Reuters) - Philippine police and the FBI have arrested four people that Manila said were paid by a Saudi Arabian-based group to hack into US telecom AT&T's system, but the company said it was neither targeted nor breached. The Philippines' Criminal Investigation and Detection Group (CIDG) said those arrested in Wednesday's operation in Manila with the Federal Bureau of Investigation were paid by the same group the FBI said had funded the November 2008 attacks in Mumbai. "The hacking activity resulted in almost $2 million (1 million pound) in losses incurred by the company," the CIDG said in a statement.
