The US State Department has announced it has raised a reward to $10 million for information about North Korean state-backed threat actors.

“If you have information on any individuals associated with the North Korean government-linked malicious cyber groups (such as Andariel, APT38, Bluenoroff, Guardians of Peace, Kimsuky, or Lazarus Group) and who are involved in targeting US critical infrastructure in violation of the Computer Fraud and Abuse Act, you may be eligible for a reward,” the State Department said in a tweet.

Back in April, the US authorities offered a reward of up $5 million for information on “financial and malicious cyber activities of IT workers who generate funds that contribute to North Korea's WMD and ballistic missile programs.”

In May, the department warned organizations of the risk of accidentally hiring North Korean hackers posing as non-nationals secretly working for Kim Jong-un’s regime.

Last week, the US Department of Justice announced it seized nearly half a million dollars in cryptocurrency paid last year as ransom by a hospital in Kansas and medical provider in Colorado to hackers linked to North Korea.

Recently, Microsoft released a report detailing ransomware attacks by North Korean hackers against small businesses in various countries.
