Chinese hackers targeted government and government-linked organizations worldwide, exploiting a zero-day vulnerability in Barracuda Email Security Gateway (ESG), with a particular focus on entities in the Americas, according to a report by Mandiant. Almost one-third of the hacked appliances belonged to government agencies, and the attacks were motivated by espionage, with a threat actor known as UNC4841 exfiltrating data from high-profile users in government and high-tech industries. Despite patches, the FBI warns that compromised devices are still being targeted, and advises customers to replace hacked appliances and investigate potential breaches.
