T-Mobile, AT&T, and Verizon have all issued statements confirming that their networks are now free of the Salt Typhoon hacking group, which is believed to be a Chinese state-funded operation.
The hackers had previously infiltrated U.S. telecom networks, including Verizon and AT&T, with the intention of gathering intelligence on foreign matters.
T-Mobile clarified that it was not one of the nine U.S. telecom companies identified by the government as being attacked by Salt Typhoon.
The carrier also emphasized that it never claimed to have been breached by the group and that it found no signs of attackers within its system.
Importantly, T-Mobile assured that sensitive customer information, including voicemails, call logs, and texts, was never accessed.
In contrast, AT&T and Verizon admitted that their networks were compromised but stated that they had successfully contained the attacks.
AT&T explained that the hackers were targeting foreign intelligence, while Verizon revealed that high-profile individuals in government and politics, including President-elect Donald Trump and Vice President-elect J.D. Vance, were among the targeted victims.
Verizon reported that it had not detected any ongoing threat actor activity and had resolved the issue after significant work.
Both companies emphasized that they had notified affected individuals and cooperated with law enforcement throughout the investigation.
While the Biden administration has acknowledged the breach, it remains unclear how many Americans were affected or when the hackers will be fully cleared from U.S. telecom systems.
However, the confirmation that T-Mobile, AT&T, and Verizon have cleared their networks of the attackers is a positive step forward.
