China's 'FamousSparrow' APT Nests in South Caucasus Energy Firm

A China-linked cyber espionage group called FamousSparrow has been discovered targeting an oil and gas company in Azerbaijan, marking the first time Chinese threat actors have been found operating in Azerbaijani industries. The group used sophisticated DLL sideloading techniques and repeatedly breached the company between December and February because the victim failed to patch a vulnerable Microsoft Exchange server after initially detecting and cleaning infected workstations. This attack represents China's expanding cyber operations into the South Caucasus energy corridor, a region traditionally within Russia's sphere of influence that has become increasingly important for European energy supplies.
