He stayed up there for hours and came down just before 5 a.m., after conducting an interview with the New York Daily News. Malone was arrested around 5:30 a.m. after descending from his climb.
For his high climbs, Malone, pleaded guilty to misdemeanor reckless endangerment.
He was sentenced to “a conditional discharge,” which, in English, means that if he does five days of community service and is not rearrested in the next six months, the case against him will be dismissed.
Defense lawyer Robert Gottlieb said Malone took "extraordinary" precautions to make sure nobody was hurt.
Malone told the New York Daily News that he picked the wee hours for his climb because he was "trying to minimize any disturbance - any breach of the peace." He told no one in advance, he said.
Malone said that he had dropped out of the University of Michigan at Ann Arbor in 1995 to study Al Qaeda full-time, the New York Daily news reported in July.
He was the third person to climb the facade of the 52-story skyscraper.
