Russian suspect in bank account takeovers is extradited to US
Russian web developer Sergei Filimonov was extradited from Georgia to the US to face charges in a multimillion-dollar bank account takeover fraud.
Sergei Anatolyevich Filimonov, 36, appeared in an Atlanta federal court on September 4 and pleaded not guilty to bank fraud, wire fraud, access device fraud, and aggravated identity theft charges. Prosecutors say that from November 2023 to October 2025 his group bought sponsored search-engine links that diverted online banking customers to spoofed login pages, stole their credentials, and initiated unauthorized wire transfers. The FBI linked the scheme to the December 2025 seizure of the domain web3adspanels.org, identifying at least 19 victims, roughly $14.6 million in confirmed losses, and about $28 million in attempted losses.

Fraudsters steal $6 million from Tectonic crypto platform after inflating token price
Attackers inflated Tectonic's Tonic token price 100x in 20 minutes and borrowed $74 million against it, stealing $6 million before Cronos halted activity.
Attackers manipulated the price of Tectonic's thinly traded Tonic token, raising it more than 100-fold in 20 minutes, then used the inflated tokens as collateral to borrow assets in an attempted $74 million theft. About $6 million left the platform; Cronos halted blockchain activity and later restored roughly $69 million in frozen funds via an on-chain rollback. Tectonic plans a phased reopening and a postmortem. TRM Labs says market manipulation now accounts for one in eight crypto hacks, with 32 incidents in 2026, and compares the case to the 2022 Mango Markets manipulation that led to a criminal conviction.
