Breach exposes FBI data links

Sensitive call logs linked to FBI agents have been exposed in a hacking incident targeting telecom giant AT&T, raising urgent questions about cybersecurity vulnerabilities and informant safety.

A major data breach involving telecom provider AT&T has compromised sensitive information about FBI agents’ call and text logs. The incident, which occurred last year, exposed phone numbers and contact details, though not the content of communications. FBI officials warn that the breach may risk revealing the identities of confidential informants.

AT&T reported in July that hackers had stolen records linked to 109 million customer accounts. Among the stolen data were months of FBI call logs, potentially connecting agents to their sources. While AT&T claims to have collaborated with law enforcement to mitigate the damage, the FBI continues to prioritise protecting its informants.

The breach has reignited concerns about cyber-espionage targeting US telecom networks. Earlier this month, the US national security adviser highlighted ongoing threats from Chinese-linked cyber operations. Although telecom firms, including AT&T and Verizon, say their systems are now secure, the incident underscores the persistent risks posed by sophisticated hackers.
