Bybit's real-time systems stop cross-chain fake-deposit attack, averting potential loss of 1B+ DOT

Bybit's Group Risk Control team detected and blocked a series of coordinated fake deposit attacks across multiple blockchains, actions the exchange says prevented potential losses exceeding 1 billion DOT and were neutralized in real time ^{[1] [2]}.

Reports describe attackers using batch transactions and ownership-manipulation techniques to simulate deposits without actual fund transfers; Bybit applied a multi-stage validation framework to identify and reject those fake deposits ^{[3] [2]}.

Bybit confirmed that no funds were incorrectly credited and no users were affected, attributing the outcome to its real-time controls and risk-detection systems ^{[1] [4]}.

The exchange says its detection and validation measures stopped the coordinated scheme before any losses occurred, highlighting the role of on-chain monitoring and risk controls in defending against complex deposit-manipulation attacks ^{[1] [3]}.
