Uzbek entrepreneur faced US sanctions

The US Department of the Treasury's Office of Foreign Assets Control (OFAC) has added Uzbek citizen Azizjon Mamashoyev to the sanctions list. This was reported by Zamin.uz.

According to American sources, Mamashoyev collaborated with a group of Russian hackers and participated in activities threatening global cybersecurity. Mamashoyev and his company Advance Security Solutions have been included in the US special "blacklist" (SDN).

All assets of individuals on this list in the US are frozen, and US companies and citizens are prohibited from establishing economic relations with them. According to investigation data, Advance Security Solutions was registered in Dubai in 2025, but its legal address is also recorded in Tashkent.

The company operated in the field of "offensive cybersecurity" and was engaged in selling information about system vulnerabilities. Additionally, the company participated in distributing technologies intended to breach computer systems.

Along with Mamashoyev, several Russians, including Sergey Zelenyuk, have also been added to the sanctions list. Zelenyuk is suspected of organizing attacks on US government agencies and medical institutions through malicious software.

Uzbek citizen Mamashoyev is accused of providing technical and material support to this group. This is not the first case of companies connected to Uzbekistan facing US sanctions.

In 2025, restrictions were also imposed on the "Datavice" company for supporting Russian military technical infrastructure. Such cases indicate that international organizations are increasing their attention to cyber activities in the region.

How effective can international sanctions be as a tool in combating cybercrime? Opinions on this matter vary.
