The U.S. Federal Bureau of Investigation and police in the Philippines  have jointly busted a ring of four alleged hackers in Manila with  connections to a terrorist group in Saudi Arabia, the Criminal  Investigation and Detection Group of the Philippines police said last  week.
 
 FBI agents, who have been investigating hacking of telecommunication  companies in the U.S. and in the country since 1999, have uncovered a  "paper trail" of various bank transactions allegedly linking the local  hackers to the cell in Saudi Arabia, whose activities include financing  terrorist activities, CIDG said in a statement.
 
 The operation last week followed a complaint from AT&T, which  suffered losses of up to US$2 million as a result of a hack of its  system, the Philippines police agency said.
 
 The Philippines police said that Muhammad Zamir, a Jemaah Islamiyah  member, paid the suspects  to hack the trunk-line of different  telecommunication companies including AT&T.  Revenue derived from  the hacking was diverted to the account of the terrorists, who paid the  Filipino hackers on a commission basis through local banks, CIDG said. 
 
 Jemaah Islamiyah is an Islamic militant group that has been active in  South East Asia and is said to be linked to some terrorist attacks in  the region, including the Bali bombing in 2002.
 
 AT&T and the FBI were not immediately available for comment. AT&T said last week that there was an attempt to obtain information on a number  of AT&T customer accounts, but said  it did not believe that the  perpetrators of the attack obtained access to users' online accounts.
 
 Zamir was arrested in Italy in 2007 by FBI operatives but his group  continues to be active, and was later tagged by the FBI to be the  financial source of the terrorist attack in Mumbai, India on Nov. 26,  2008. After Zamir's arrest, an unnamed  Saudi national took charge of  the operation of the group, and also maintained links with the group of  hackers  in Manila, CIDG said. 
 
 In March, FBI requested the assistance of CIDG Anti-Transnational and  Cyber Crime Division after it found that the terrorist group had  targeted AT&T in the U.S., and the same group of Filipino hackers  was involved, CIDG said.
