Hacker documents show NSA tools for breaching global money transfer system

Documents and computer files released by hackers provide a blueprint for how the U.S. National Security Agency likely used weaknesses in commercially available software to gain access to the global system for transferring money between banks, a review of the data showed.

On April 14, a group calling itself the Shadow Brokers released documents and files indicating NSA had accessed the SWIFT money-transfer system through service providers in the Middle East and Latin America. That release was the latest in a series of disclosures by the group in recent months.

Matt Suiche, founder of cybersecurity firm Comae Technologies, wrote in a blog post that screen shots indicated some SWIFT affiliates were using Windows servers that were vulnerable at the time, in 2013, to the Microsoft exploits published by the Shadow Brokers. He said he concluded that the NSA took advantage and got in that way.

"As soon as they bypass the firewalls, they target the machines using Microsoft exploits," Suiche told Reuters. Exploits are small programs for taking advantage of security flaws. Hackers use them to insert back doors for continued access, eavesdropping or to insert other tools.

"We now have all of the tools the NSA used to compromise SWIFT (via) Cisco firewalls, Windows," Suiche said.

Reuters was not able to independently verify the authenticity of the documents released by the hackers.

Microsoft  acknowledged the vulnerabilities and said they had been patched. Cisco Systems Inc has previously acknowledged that its firewalls had been vulnerable.

Cisco and the NSA did not reply to requests for comment. Belgium-based SWIFT on Friday downplayed the risk of attacks employing the code released by hackers and said it had no...
