CNBC:
A Chinese state-sponsored hacking group successfully compromised the computer networks of at least six U.S. state governments between May 2021 and February this year, according to research published by cybersecurity firm Mandiant on Tuesday.
The group, known as APT41, allegedly exploited vulnerabilities in web applications to get their initial foothold into state government networks, Mandiant said.
APT41, which Mandiant claims carries out state-sponsored espionage on behalf of Beijing, took advantage of software flaws and quickly exploited security vulnerabilities that were made public by researchers.
