The US Treasury on Tuesday sanctioned three Chinese individuals and three
Thai companies
for involvement in a
cybercrime network
that it said made
bomb threats
and fraudulent applications for COVID-related aid, costing the government billions of dollars.
The individuals and the Thai-based companies were sanctioned for activities related to
911 S5 botnet
, a service that compromised computers and resulted in cybercrimes being traced back to victims' computers instead of the perpetrators' devices, the Treasury said.
"These individuals leveraged their malicious botnet technology to compromise personal devices, enabling cybercriminals to fraudulently secure economic assistance intended for those in need and to terrorize our citizens with bomb threats," said the Treasury under secretary for terrorism and financial intelligence, Brian Nelson.
The IP addresses compromised were linked to a number of bomb threats made across the United States in July 2022, according to the release.
Reuters was not immediately able to seek comment from the sanctioned entities or individuals.
