The U.S. Treasury Department's Office of Foreign Assets Control (OFAC) has imposed sanctions on the Russian IT company Aeza Group for hosting infostealers and ransomware operations, according to a press release published on July 1.

Restrictions were imposed on two subsidiaries and four members of the Aeza Group's management as well, the statement read.

The U.S. Treasury Department characterized Aeza as a "bulletproof hosting service" that provided services to the Meduza and Lumma infostealers, as well as to the BianLian and RedLine ransomware groups.

Aeza Group also hosted the Russian-language darknet marketplace for illegal drugs, BlackSprut.

According to the U.S. Treasury Department, Aeza Group sells access to specialized servers that help cybercriminals avoid detection and resist attempts by law enforcement agencies to suppress their criminal activities.

Sanctions against the company involve blocking all assets of the named individuals located in the U.S. Any legal entities that are owned, directly or indirectly, individually or in the aggregate, by 50% or more by one or more of the mentioned individuals are also blocked.

Violation of the U.S. sanctions may result in civil or criminal penalties.

The news comes as Ukraine continues to call on the U.S. to strengthen sanctions against Russia. Despite Russia's refusal to accept the ceasefire proposal and its army's ongoing advance across Ukrainian territory, the Trump administration has not yet imposed new restrictions.

Meanwhile, Senators Lindsey Graham (R) and Richard Blumenthal (D) introduced a bill to impose a 500% tariff on imports from countries that continue to buy Russian oil and raw materials.

The legislation currently has broad bipartisan support, with 82 out of 100 U.S. senators backing it. U.S. House Speaker Mike Johnson also voiced his support for the bill.
