The former hacker was known for infiltrating systems like Microsoft, Yahoo and The New York Times. He was more widely known for his involvement in giving information to whistleblower Chelsea Manning, who was a former U.S. Army soldier. The two became friends and Manning reportedly told Lamo that she had planned on leaking classified information.

Lamo and two of his friends who were in military intelligence turned Manning in, which lead to her arrest. She was sentenced to 35 years in prison, but her sentence was commuted by President Barack Obama. Manning was released in 2017.

Lamo's cause of death had not yet been released.
