Pimentel said. The "internal system error" resulted in unauthorized withdrawals and deposits, and double crediting for some accounts, sowing fear and chaos among BPI's depositors. Pimentel said Philippine banks ?must be on the lookout for a possible cyberattack as hackers worldwide have already victimized a number of banking institutions despite safeguard measures to preempt the commission of the crime." BPI president Cezar Consing, however, maintained that the problem was not caused by hacking. Ako Bicol partylist Congressmen Rodel Batocabe, Alfredo Garbin and Christopher Co filed House Resolution 1072, seeking a probe on the BPI mess. "We need to conduct an investigation to find out about the root cause of the BPI internal error and to determine the most suitable safeguards in order to prevent such future incident happening not only in BPI but in other banks and financial institutions," Batocabe said.
