"Because numerous documents in the data dump appear to be classified, members of the intelligence community will have a hard time legally reviewing them to determine the full extent of the damage", Thomas added.
He's been among the researchers looking over the files and has found they contain about 20 different Windows-based exploits - four of which appear to leverage previously unknown software vulnerabilities.
Experts say the document dump-which is mostly lines of computer code-amounts to an emergency for Microsoft because the hacks consist of a variety of "zero-day exploits" that can serve to infiltrate Windows machines for purposes of espionage, vandalism, or document theft. One collection of 15 exploits contains at least four Windows hacks that researches have already been able to replicate.
Matthew Hickey, cofounder of British security shop Hacker House, told The Register FUZZBUNCH is a very well-developed package that allows servers to be penetrated with a few strokes of the keyboard. Hickey was able to test out exploits in his United Kingdom firm's lab and confirmed they "work just as they are described".
The mysterious tragicomic hacking group The Shadow Brokers continues to dump incredibly compromising cyberweapons and internal information looted from the NSA, accompanied by Borat-compliant gibberish that reads like someone trying to make you guess whether there's a false flag in play, and if so, who is waving it.
On April 8, the group published a batch of NSA exploits it had previously tried, and failed, to sell.
The documents released by the Shadow Brokers on Friday indicate that the NSA may have accessed the SWIFT network through service bureaus. Files released by the group have been of varying ages; the last release from the Shadow Brokers contained vulnerabilities to operating systems that were borderline archaic. Any hackers can now download the tools and learn from them.More news: France election: Far-left Melenchon enjoys late poll surge
Hickey said it exploits Windows systems over TCP ports 445 and 139.
The NSA did not immediately respond to requests for comment, AP reported.
There is still no definitive evidence showing the government did or did not tell Microsoft of the swaths of exploits Shadow Brokers allegedly stole from it.
"At this time, other than reporters, no individual or organization has contacted us in relation to the materials released by Shadow Brokers", a Microsoft spokesperson said in an email.
According to Motherboard, the most risky program in the release is an NSA program known as FUZZBUNCH, "a hacking suite or toolkit that contains several plug-and-play exploits to attack several versions of Windows operating system". The leaked documents contain notes about passwords, configuration data and networks.
The released may also cause substantial diplomatic fallout, as the USA government's access to SWIFT has always been controversial.
Now it seems that the NSA gained access to SWIFT customer accounts through one of SWIFT's service bureaus to monitor money flow in the Middle East, although EastNets has denied the claim.
