Bulgaria arrested a Russian native and the likely RSOCKS botnet owner in June 2022 at the US' request; he asked for, and was granted, extradition to the US
A 36-year-old Russian man recently identified by KrebsOnSecurity as the likely proprietor of the massive RSOCKS botnet has been arrested …
Context & Ripple Effects
The June DOJ-led disruption of RSOCKS, a Russian botnet that hijacked millions of devices as proxy servers, now has a named suspect: a 36-year-old Russian arrested in Bulgaria at Washington's request and extradited after he asked for it himself.
The playbook mirrors the Levashov case — Spain arrested him at FBI request in 2017, and he pleaded guilty in US District Court by September 2018 (guilty plea). The difference is that this suspect waived any fight over extradition, shortening the path from arrest to US prosecution.
First-order effects
- The likely RSOCKS operator now faces US prosecution rather than release or prosecution in Bulgaria, closing the loop on an operation that had already seized the botnet's infrastructure in June.
- Customers who rented RSOCKS proxies for anonymizing malicious traffic lose their supplier for good, since both the infrastructure and its proprietor are out of circulation.
Second-order effects
- Operators of comparable proxy botnets face a two-front threat: infrastructure seizures like the DOJ's June action plus personal exposure when they travel to jurisdictions willing to execute US arrest requests.
- Allied European states are again demonstrating willingness to act as the arrest point for Russian cyber suspects who cannot be reached inside Russia, reinforcing the extradition corridor Spain used for Levashov.
Third-order effects
- If the pattern holds — third-country arrest at US request, extradition, US plea — running criminal botnet infrastructure from Russia offers less protection whenever operators travel abroad, raising the personal cost of the proxy-for-hire trade.
- The DOJ's combination of technical disruption and physical arrest is consolidating into a repeatable template against botnet proprietors, shifting deterrence from infrastructure alone to the individuals behind it.
The trend: US-led botnet enforcement is maturing from infrastructure takedowns into end-to-end prosecutions, using allied-country arrests and extradition to reach operators sheltered in Russia.
