On Friday, the hackers released the most significant batch of tools targeting vulnerabilities in a long line of Windows operating systems. Using those, nearly anyone with sufficient technical knowledge can hack millions of Microsoft users.
Security researchers are currently exploring the files trying to determine the capabilities of the alleged exploits, already dubbed by Edward Snowden the NSA's "Top Secret arsenal of digital weapons".
"This is as big as it gets," said security researcher and hacker Matthew Hickey.
"Nation-state attack tools are now in the hands of anyone who cares to download them…it's literally a cyberweapon for hacking into computers…people will be using these attacks for years to come."
The new dump includes 23 additional hacking tools named OddJob, EasyBee, EternalRomance, FuzzBunch, EducatedScholar, and others. The tools are capable of breaking into computers running version of the Windows operating system earlier than the most recent Windows 10.
It is possible, however, that Shadow Brokers are holding back on releasing more tools and exploits.

He also suggested that the NSA may have known the leak was coming but failed to warn Microsoft.

The release contains evidence that the Intelligence agency used the tools to hack the SWIFT banking system of several banks around the world. SWIFT is a global financial messaging system that thousands of banks and organizations use to transfer billions of dollars daily.
A Microsoft spokesperson said the company is reviewing the report and "will take the necessary actions to protect the customers".
