A Russian national was indicted for Ransomware Attacks on US law enforcement, government agencies, schools, and healthcare facilities in which he extorted as much as $200 million from victims, the US Justice Department announced on Tuesday.

Around 2020, Mikhail Pavlovich Matveev allegedly engaged in three malware campaigns to attack thousands of people and demanded around $400 million.

“From Russia and hiding behind multiple aliases, Matveev is alleged to have used these Ransomware strains to encrypt and hold hostage for ransom the data of numerous victims, including hospitals, schools, nonprofits, and law enforcement agencies, like the Metropolitan Police Department in Washington, DC,” said US Attorney Philip Sellinger for the District of New Jersey.

The US government is offering a $10 million reward for information that could lead to Matveev’s arrest.
