SHANGHAI—A Chinese malware broker who was sentenced in the United States this year for dealing in malicious software linked to major hacks is back at his old workplace: teaching high-school computer courses, including one on internet security.
Yu Pingan, who spent 18 months in a San Diego federal detention center, had pleaded guilty to conspiracy to commit computer hacking. A high school instructor, he had been arrested at Los Angeles International Airport in August 2017 upon arriving with a group of teachers to observe a U.S. university. A Reuters reporter found him teaching at his old school here last month.
