Earlier this year, two hackers broke into a computer and soon realized the significance of what this machine was. As it turned out, they had landed on the computer of a hacker who allegedly works for the North Korean government.

The two hackers decided to keep digging and found evidence that they say linked the hacker to cyberespionage operations carried out by North Korea, exploits and hacking tools, and infrastructure used in those operations.

Saber, one of the hackers involved, told TechCrunch that they had access to the North Korean government worker’s computer for around four months, but as soon as they understood what data they got access to, they realized they eventually had to leak it and expose what they had discovered.

“These nation-state hackers are hacking for all the wrong reasons. I hope more of them will get exposed; they deserve to be,” said Saber, who spoke to TechCrunch after he and cyb0rg published an article in the legendary hacking e-zine Phrack, disclosing details of their findings.

There are countless cybersecurity companies and researchers who closely track anything the North Korean government and its many hacking groups are up to, which includes espionage operations, as well as increasingly large crypto heists and wide-ranging operations where North Koreans pose as remote IT workers to fund the regime’s nuclear weapons program.
