REUTERS/Raphael Satter/Photo Illustration The announcement on Friday is the first time Facebook has publicly exposed an offensive hacking operation and, if confirmed, would be a rare case of suspected state-backed cyberspies being tracked to a specific organisation. The hackers, known as OceanLotus or APT32, have been accused for years of spying on political dissidents, businesses and foreign officials. Reuters reported this year that the group had attempted to break into China’s Ministry of Emergency Management and the government of Wuhan as the COVID-19 outbreak first spread.
