Chinese hackers launch massive cyber espionage campaign globally.

Chinese hackers, suspected to be state-backed, used a security hole in Barracuda Networks' Email Security Gateway to breach hundreds of public and private sector organizations globally, including nearly a third of government agencies. The hackers sent emails containing malicious file attachments to gain access to targeted organizations' devices and data. The majority of the impact was in the Americas, reflecting the geography of Barracuda's customer base. The activity began as early as October and was focused on issues that are high policy priorities for China, particularly in the Asia Pacific region.
