An ambitious group of state-backed hackers has been burrowing into telecommunications companies in order to spy on high-profile targets across the world, a U.S. cybersecurity firm said in a report published yesterday.
Boston-based Cybereason said the tactic gave hackers sweeping access to VIPs’ call records, location data and device information — effectively turning the targets’ cellular providers against them.
Cybereason Chief Executive Lior Div said that because customers weren’t directly targeted, they might never discover their every movement was being monitored by a hostile power.
The hackers had turned the affected telecoms into “a global surveillance system,” Div said in a telephone interview ahead of the report’s launch.
“Those individuals don’t know they were hacked — because they weren’t.”
Div, who is presenting his findings at the Cyber Week conference in Tel Aviv, provided scant details about who was targeted in the hack.
