Society for Worldwide Interbank Financial Telecommunication (SWIFT) announced that the same hacker group that stole $101 million from Bangladesh's central bank is believed to have struck again, this time in Vietnam, according to CNN Money. SWIFT, which enables financial institutions around the world to make transfers to each other, said it believes the previous heist, which attempted to steal $800 million only to be caught by a typo, was not an isolated incident but part of a larger campaign.

While SWIFT did not name any specific attack in a particular country as evidence of this, BAE Systems, a British Defense Contractor, believes that the victim was a Vietnamese commercial bank, said CNN Money. BAE said the malware used on the Vietnamese bank, while custom-tailored specifically for that target, came from the same code base that was used in the Bangladesh attack. This has led the contractor to believe the same group probably did both attacks. While this alleged group's identity remains unknown, BAE has also linked it to the hack on Sony in 2014.
