China-linked threat actors compromised some U.S. internet service providers as part of a cyber espionage campaign code-named Salt Typhoon.
The state-sponsored hackers aimed at gathering intelligence from the targets or carrying out disruptive cyberattacks.
The Wall Street Journal reported that experts are investigating into the security breached to determine if the attackers gained access to Cisco Systems routers, which are core network components of the ISP infrastructures.
