Red Menshen, a threat group linked to China, has been discovered infiltrating telecom networks to conduct espionage against government entities. This ongoing campaign involves stealthily implanting access mechanisms that allow attackers to maintain a foothold within critical infrastructure. Researchers have identified these implants, referred to as BPFDoor, which facilitate covert data collection and surveillance. The implications of this activity are significant, as it jeopardizes sensitive government communications and could lead to broader security risks. The sustained nature of this campaign suggests that the threat is not only immediate but also part of a larger strategy targeting national security interests.
