Hackers, most likely from China, have been spying on governments and businesses in Southeast Asia and India uninterrupted for a decade, researchers at internet security company FireEye Inc said. Bryce Boland, Chief Technology Officer for Asia Pacific at FireEye and co-author of the report, said the attack was still ongoing, noting that the servers the attackers used were still operational, and that FireEye continued to see attacks against its customers, who number among the targets. He said the group appeared to include at least two software developers. The report did not offer other indications of the possible size of the group or where it's based.
