The hacker Adrian Lamo died at age 37, according to ZDNet and a Facebook post by his father. The circumstances of Lamo's death are unknown, but a coroner in Sedgwick County, Kansas, confirmed the news.
Lamo was known in the early 2000s for hacking several company networks, including the New York Times Company. Sometimes called the "homeless hacker" for his nomadic life, he pleaded guilty in 2004 to violating the Times internal network and accumulating tens of thousands of dollars in search fees on his Lexis-Nexis account. Prior to that, he warned several other security breach companies, including WorldCom and Microsoft.
More recently, however, Lamo was known to alert the Army after the whistleblower Chelsea Manning confided in him about leaking classified material to WikiLeaks. Lamo said he acted out of a sense of "duty," but later expressed some regret over the decision, although he kept it in later interviews. "A bright mind and compassionate soul is gone," wrote Lamo's father on Facebook.
