A Philippine senator said on Wednesday that Chinese hackers were likely to have pulled off one of the world's biggest cyber heists at the Bangladesh central bank, citing the network of Chinese people involved in the routing of the stolen funds through Manila.

Unidentified hackers infiltrated the computers at Bangladesh Bank in early February and tried to transfer a total of $951 million from its account at the Federal Reserve Bank of New York.

All but one of the 35 attempted transfers were to the Rizal Commercial Banking Corp. (RCBC), confirming the Philippines' centrality to the heist.
