A zero-day vulnerability tool, covertly exploited by US intelligence agencies and exposed by the Shadow Brokers hacking group has been blamed for the massive spread of malware that infected tens of thousands of computer systems globally.

The ransomware virus which extorts Windows users by blocking their personal files and demanding payment to restore access, allegedly exploits a vulnerability that was discovered and concealed for future use by the National Security Agency (NSA), according to a range of security experts.

This exploit (codenamed “EternalBlue”) has been made available on the internet through the Shadowbrokers dump on April 14th, 2017,” Russian cybersecurity firm, Kaspersky Lab, wrote in a blog post about the attack.

Meanwhile, NSA whistleblower Edward Snowden has led the discussion on NSA’s role and responsibility in Friday’s extensive cyberattacks, noting that if the NSA had “privately disclosed the flaw used to attack hospitals when they found it, not when they lost it, this may not have happened.”

Snowden noted that the NSA developed these “dangerous attack tools that could target Western software” despite warnings, and that it’s now up to Congress to question the agency on its knowledge of any other software vulnerabilities.

Wikileaks also referred to its dealings with the whistleblower behind its Vault 7 CIA releases who warned of the extreme proliferation risk in the creation of cyber weapons.
