According to information published in the media, the US Department of the Treasury has added Uzbek citizen Azizhon Mamashoev and his company Advance Security Solutions to the sanctions list. This organization is suspected of activities related to cybersecurity, specifically as a broker for exploits (tools for hacking).
The Office of Foreign Assets Control (OFAC) of the US Department of the Treasury announced the imposition of sanctions against Mamashoev and his company. The list includes his passport details and identification numbers. Mamashoev, born in 1987, also has connections with Sergey Zelenyuk.
Advance Security Solutions, registered in 2025, operates in the field of programming, with offices in Tashkent and Dubai (UAE). According to OFAC, this company was established by Mamashoev and works in the area of offensive cybersecurity.
The agency's statement emphasizes that Advance Security Solutions acts as a broker for exploits and, similar to Operation Zero, offers rewards for vulnerabilities in American software. The company was added to the list by a decree from the US president as being controlled by Mamashoev or acting on his behalf.
Additionally, sanctions have affected Oleg Vyacheslavovich Kucherov, a citizen of Russia, who, according to OFAC, is an alleged participant in the cybercriminal group Trickbot. This group, identified in 2016, used modular malware for cyberattacks, including ransomware attacks on US government agencies and medical organizations.
According to OFAC information, Mamashoev and Kucherov previously collaborated with Operation Zero. Their inclusion in the sanctions list is linked to providing significant financial, material, or technological support to Sergey Zelenyuk or acting in his interests.
Inclusion in the SDN List means blocking assets within the United States and prohibits American citizens from engaging in any transactions with them.
