With the lists and details shared by the Redmond software giant, it appears that the company either bought the exploits directly from Shadow Brokers ahead of the public release or NSA gave the company a heads-up - Microsoft isn't sharing what exactly happened, though.
The infamous whistleblower described the exposure of the files as the "Mother Of All Exploits" on Twitter, writing that the release of the files was "wrecking the internet". SWIFT stated that there was no indication that their main network had been accessed by unauthorized users.
Microsoft did not immediately respond to a request for comment.
Criminals stole millions of dollars from Bangladesh's central bank after Swift was targeted by hackers previous year.
EastNets is one of 74 local service bureaus worldwide certified by Swift, acting as an interface between the global network and smaller banks and financial institutions in the Middle East. "Once validated, engineering teams prioritize fixing the reported issue as soon as possible, taking into consideration the time to fix it across any impacted product or service, as well as versions, the potential threat to customers, and the likelihood of exploitation". Documents included in the leak suggest at least one major bureau, EastNets, may have been compromised.
"This is the equivalent of hacking all the banks in the region without having to hack them individually", Suiche said.
"This reportedly gave the United States spy service a window into the financial activities of a range of organisations, including those belonging to firms in Qatar, Dubai, Abu Dhabi, Syria, Yemen and the Palestinian territories", said a report in The Wired on Saturday.
Microsoft's response comes hours after unnecessary fear from several security researchers, including one who advised Windows users to turn off their machines for the weekend.
"While we cannot ascertain the information that has been published, we can confirm that no EastNets customer data has been compromised in any way", said the EastNets founder and chief executive Hazem Mulhim in a statement sent to The National.
The NSA targeted nine computer servers at a SWIFT contractor, Dubai-based service bureau EastNets, according to the documents. This means that customers should be protected if they've kept their software up-to-date.
That said, multiple experts said the sheer number of zero days released at the same time was unprecedented.
The researcher was able to run numerous exploits found in the cache, according to a tweet. The group attempted to auction off the files but failed, and have been releasing portions of the stolen files in stages. The hacking tools, likely originating from the NSA, were released online yesterday, and Microsoft was able to test and confirm patches are already available for all now supported versions of Windows.
