Hackers who exposed North Korean government hacker explain why they did it

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.

In this case, Saber and cyb0rg went one step further and actually hacked the hackers, an operation that can give more, or at least different, insights into how these government-backed groups work, as well las “what they are doing on a daily basis and so on,” as Saber put it. 

The hackers want to be known only by their handles, Saber and cyb0rg, because they may face retaliation from the North Korean government, and possibly others. Saber said that they consider themselves hacktivists, and he namedropped legendary hacktivist Phineas Fisher, responsible for hacking spyware makers FinFisher and Hacking Team, as an inspiration.

At the same time, the hackers also understand that what they did is illegal, but they thought it was nonetheless important to publicize it. 

“Keeping it for us wouldn’t have been really helpful,” said Saber. “By leaking it all to the public hopefully we ca …
