China-linked spies are still lurking inside U.S. telecommunications networks roughly six months after American officials started investigating the intrusions, senior officials told reporters Tuesday. From a report: This is the first time U.S. officials have confirmed reports that Salt Typhoon hackers still have access to critical infrastructure — and they’re proving difficult to kick out. Officials added that they don’t yet know the full scope of the intrusions, despite starting the investigation in late spring.
The Cybersecurity and Infrastructure Security Agency and FBI released guidance Tuesday for the communications sector to harden their networks against Chinese state-sponsored hackers. The guide includes basic steps like maintaining logs of activity on the network, keeping an inventory of all devices in the telecom’s environment and changing any default equipment passwords. The hack has given Salt Typhoon unprecedented access to records from U.S. telecommunications networks about who Americans are communicating with, a senior FBI official told reporters during a briefing.
