Chinese Hackers Breached US Telecom Firm Earlier Than Previously Known

Corporate investigators uncovered evidence that Chinese hackers infiltrated an American telecommunications company in the summer of 2023, suggesting a breach of the US communications system earlier than publicly reported. Investigators discovered malware linked to Chinese state-sponsored hacking groups residing on the company's systems for seven months, starting in summer 2023. An unclassified report, shared with Western intelligence agencies, confirms the intrusion but omits the name of the affected company.
