A lone U.S. hacker who goes by the handle “P4x” is claiming responsibility for shutting down the entire North Korean internet twice last month.

The anonymous hacker says that he was taking revenge for a North Korean cyberattack on Western security researchers carried out by North Korean spies last year. He says he was frustrated by the lack of response from the U.S. over the attack and decided to take matters into his own hands.

It’s doubtful that P4x’s actions had any effect on the North Korean state or government. Only a tiny fraction of their people have access to the internet. And the hackers that disrupted P4x’s work on security systems, for which he was exacting revenge, are probably not even located in North Korea. They are probably based in China, where Beijing has its own cyber warfare group, PLA Unit 61398.

Nevertheless, striking a blow against America’s enemies is always welcome — no matter where it comes from.
