Chinese hacking group APT41 has been targeting US states in a tenacious and adaptive campaign, according to cybersecurity company Mandiant.
At least six US states have been targeted by hackers linked to China who exploited vulnerabilities in web programs.
"APT41's recent activity against US state governments consists of significant new capabilities," researchers at cybersecurity company Mandiant said on Tuesday.
Notorious Chinese hacking group APT41 has been targeting US states in a tenacious and adaptive campaign, according to a Mandiant report.
From last May to this February, the group compromised at least six state government networks by exploiting vulnerabilities in internet-facing programs including an animal health reporting app, according to Mandiant.
Victims and data targeted by hackers were "consistent with an espionage operation" Mandiant said, but did not rule out that the motive could have been money given the group's "history of moonlighting for personal financial gain."
APT41 quickly adapted attacks to take advantage of new computer vulnerabilities that were made public, according to Mandiant.

'Persistent cyber espionage'
For example, within hours of Apache Foundation announcing a critical flaw, the hackers began taking advantage of it and compromised at least two US state governments "as well as their more traditional targets in the insurance and telecommunications industries," the report said.
Mandiant researchers described APT41 as highly resourceful.
The global hacking collective has been accused by US authorities of targeting company servers for ransom, compromising government networks and spying on Hong Kong activists.
Seven members of the group – including five Chinese nationals – were charged by the US Department of Justice in late 2020 with being involved in hacking more than 100 companies around the world.
Targets included computer hardware manufacturers, telecommunications providers, social media firms, video game companies, non-profit organizations, universities, think tanks, foreign governments and pro-democracy politicians, according to justice officials.
"We assess that China presents the broadest, most active, and persistent cyber espionage threat to US government and private sector networks," said a threat assessment report released this week by the office of the US director of national intelligence.

Google announced Tuesday a deal to acquire Mandiant for about $5.4 billion, one of the tech giant's biggest purchases ever as it works to bolster its cloud computing offer.
Mandiant, which helps customers prepare for or deal with cyberattacks, is expected to join Google Cloud this year, if the acquisition is approved by regulators.
