WASHINGTON (Reuters) -The United States sanctioned a Chinese cybersecurity company over an ambitious cyberattack that U.S. Treasury officials say could have killed people.
The Treasury said in a statement on Tuesday that the Chengdu-based Sichuan Silence Information Technology Company and one of its employees, Guan Tianfeng, deployed malicious software to more than 80,000 firewalls run by thousands of companies worldwide in April 2020.
The malicious software not only stole data, but it was used to deploy ransomware, which paralyzes corporate networks by encrypting data. The statement said three dozen firewalls were protecting the systems of critical infrastructure companies and that, had the hacking not been thwarted or mitigated, the potential impact "could have resulted in serious injury or loss of human life."
In particular, the statement said that an energy company targeted in Sichuan Silence's hacking campaign was "actively involved in drilling" during the attack. Had the hacking not been thwarted, the statement said, "it could have caused oil rigs to malfunction."
Guan was separately charged with conspiracy to commit computer and wire fraud, according to a Department of Justice indictment made public on Tuesday. The FBI is offering $10 million for information about the 30-year-old, his company, or their alleged hacking activities.
Sichuan Silence did not immediately respond to an email and Reuters could not immediately locate contact information for Guan, who also goes by "gxiaomao" online.
Sichuan Silence has previously been accused of involvement in malicious digital activity. In 2021 Facebook and Instagram's parent company, Meta Platforms, alleged that the firm was linked to an online influence campaign that promoted claims of a phony biologist who said the United States was interfering in the search for the origins of COVID-19.
Beijing routinely denies being a party to hacking and other malicious cyber activity.
Ross McKerchar, the chief information security officer of the UK-based firm Sophos, whose routers were among those targeted in the cyberattack, said in a statement that the hackers had shown "relentless determination."
In a past report on the activity, Sophos said the hacks demonstrated "a level of commitment to malicious activity we have rarely seen in the nearly 40 years of Sophos' existence as a company."
