Corporate investigators found evidence that Chinese hackers broke into an American telecommunications company in the summer of 2023, indicating the country¡¯s attackers penetrated the U.S. communications system earlier than publicly known.
Investigators working for the telecommunications firm discovered last year that malware used by Chinese state-backed hacking groups was on the company¡¯s systems for seven months starting in the summer of 2023, according to a document and two people familiar with the matter. The document, an unclassified report sent to Western intelligence agencies, doesn¡¯t name the company where the malware was found and the people familiar with the matter declined to identify it.
The 2023 intrusion at an American telecommunications company came about a year before U.S. government officials and cybersecurity companies said they began spotting clues that Chinese hackers had penetrated many of the country¡¯s largest phone and wireless firms. The U.S. government has blamed the later breaches on a Chinese state-backed hacking group dubbed Salt Typhoon.
