A Vigilante Hacker Took Down North Korea’s Internet

Now, he is taking off his mask

A little more than two years have passed since the online vigilante who would call himself P4x fired the first shot in his own one-man cyberwar. Working alone in his coastal Florida home in late January of 2022, wearing slippers and pajama pants, periodically munching on Takis corn snacks, he spun up a set of custom-built programs on his laptop and a collection of cloud-based servers that intermittently tore offline every publicly visible website in North Korea and would ultimately keep them down for more than a week.

P4x’s real identity, revealed here for the first time, is Alejandro Caceres, a 38-year-old Colombian-American cybersecurity entrepreneur with hacker tattoos on both arms, unruly dark brown hair, a very high tolerance for risk, and a very personal grudge. Like many other US hackers and security researchers, Caceres had been personally targeted by North Korean spies who aimed to steal his intrusion tools. He had detailed that targeting to the FBI but received no real government support. So, he decided to take matters into his own hands and to send a message to the regime of Kim Jong Un: Messing with American hackers would have consequences.

"It felt like the right thing to do here," Caceres told WIRED at the time. "If they don’t see we have teeth, it's just going to keep coming."
