FlyCow Hack

Reported loss $65K
BNB Chain
Incorrect Share Accounting

What happened

On July 17, 2026, on-chain analysis reported that FlyCow (FCOW) was exploited for an estimated $65,258 in USDT and BNB routed to attacker-controlled addresses.

How it happened

The published analysis describes a reserve-manipulation attack on an unverified FCOW contract: it reports that the token transfer path burned FCOW from a PancakeSwap pair and called sync during transfer processing, distorting the pair's output calculation. The mechanism is a behavioral reconstruction from traces and storage events, not verified source code.
