Vietnam's Tien Phong Commercial Joint Stock Bank said it was the target of a computer attack where hackers tried to steal more than $1.13 million through the bank's connection to the Swift interbank messaging system, Reuters reported Sunday.

The attack took the form of a fraudulent transfer request for more than 1 million euros ($1.13 million), which came through a third-party service the bank used to connect to Swift and was blocked, the bank said in a statement to Reuters. Representatives of Hanoi-based Tien Phong didn't immediately return messages from Bloomberg on Sunday.

Swift, a Belgium-based organization whose technology is used by more than 11,000 banks and other institutions to initiate money transfers and perform other essential financial tasks, warned clients on Friday that hackers abusing its system had struck a second organization. The latest attempt follows one of the largest cyber heists in history: the theft of more than $80 million from the Bangladesh central bank's account at the Federal Reserve Bank of New York in February. Swift didn't name the organization, other than saying it was a commercial bank client.
