Ukrainian Man Pleads Guilty to Cybercrime Marketplace Charges, Another Administrator Arrested

Vitalii Chychasov [1] [2] [3] [4], a Ukrainian man [1] [2] [3] [4], has pleaded guilty to charges related to his role as an administrator of the cybercrime marketplace SSNDOB [1]. Another administrator [1] [2] [3] [4], Sergey Pugach [1] [2] [4], was also arrested [1] [2] [3] [4]. This article provides a detailed description of the marketplace and the illegal activities it facilitated.


Chychasov was arrested in March 2022 while attempting to enter Hungary and was subsequently extradited to the US in July 2022 [3]. He now faces a maximum penalty of 15 years in prison and has agreed to surrender the domain names associated with the offenses. Additionally, Chychasov has agreed to forfeit $5,000,000 [3], which is the estimated proceeds from his crimes [3]. The arrests were made possible by an investigation conducted by the cybercrime unit of the IRS and the FBI [4], with assistance from the U.S. [4] Department of Justice and authorities in Latvia and Cyprus [4].

The SSNDOB Marketplace was a cybercrime marketplace that operated across multiple domains and sold personal information of individuals in the United States. It generated over $19 million in sales revenue and listed personal information for millions of individuals [2]. The administrators utilized dark web forums to advertise their services [2], provide customer support [2], and protect their anonymity [2]. Stolen Social Security numbers obtained from the marketplace were used for various fraudulent activities [2], including stealing and laundering nearly $10 million [2]. The marketplace was frequented by fraudsters who used the stolen data for various schemes [1]. It listed the personal information of around 24 million victims and made millions in sales [1].


The arrest and guilty plea of Vitalii Chychasov, along with the arrest of Sergey Pugach, mark a significant step in combating cybercrime and protecting individuals from identity theft and financial fraud. The collaboration between the cybercrime unit of the IRS, the FBI [4], the U.S. [1] [3] [4] Department of Justice [4], and international authorities demonstrates the importance of global cooperation in addressing cyber threats. The forfeiture of domain names and the substantial financial penalty imposed on Chychasov serve as a deterrent to others involved in similar illegal activities. However, the scale and impact of the SSNDOB Marketplace highlight the ongoing need for robust cybersecurity measures and continued efforts to dismantle cybercrime networks.
