The U.S. government has offered $10 million for information leading to the capture of Mikhail Matveev, a ransomware developer arrested in Russia. Matveev, also known as Wazawaka, is accused of creating ransomware that targets various sectors, including healthcare. Additionally, a Brazilian hacker is facing U.S. charges for extorting $3.2 million in Bitcoin after breaching the data of 300,000 customers. This Brazilian individual allegedly threatened to release stolen data from a company in 2020. In a related development, approximately $21 million in Bitcoin payments are being seized from a Romanian national linked to cyberattacks on healthcare institutions, highlighting ongoing efforts to combat ransomware and cyber extortion.
