Security researchers have discovered a new strain of malware that uses the National Security Agency's EternalBlue exploit to hijack computers and secretly mine cryptocurrency.

In April last year, the exploit was leaked as part of a cache of alleged NSA hacking tools released by the hacker group Shadow Brokers.

Cybersecurity experts had warned that the exploit would soon be leveraged by other threat actors to power their own sophisticated and likely frequent cyberattacks.

Shortly after, the Windows exploit was used to launch the massive global WannaCry and NotPetya ransomware attacks in May and June.

Now, researchers at CrowdStrike have observed hackers leveraging the exploit to hijack victims' computers and CPU processing power to mine cryptocurrency in a new attack dubbed WannaMine.

In recent months, CrowdStrike observed a rise in cyberattacks focusing on cryptomining tools that covertly hijack CPU cycles to generate digital currencies.
