Hacked Event Broadcast

According to intelligence from the SlowMist Security Team, the YIEDL project on the BSC chain was attacked, with the attacker stealing approximately $300,000. In this incident, the reason lies in the contract’s failure to adequately validate the external parameter(dataList) provided by the user during the processing of the redeem function call. This parameter is critical data for controlling asset exchanges, typically containing specific transaction instructions or routing information. The attacker maliciously constructed this external parameter, enabling unauthorized asset transfers.

The GFA token was exploited on the BNB chain, which resulted in a loss of assets worth approximately $15,000. The root cause of the exploit is a lack of access control.

According to on-chain analyst ZachXBT's monitoring, the group of scammers who stole 8 figs with Magnate, Kokomo, Lendora, Solfire, etc is back with a new project on Blast @Leaperfinance. Last week they funded an address on Blast with ~$1M of laundered funds from the previous rugs and have begun adding liquidity to bait people in. Over time, the fraudulent team increased their TVL to over a million dollars, then stole all user funds deposited into the protocol, and forged KYC documents using low-level auditing companies. Currently, this fraudulent group has initiated scams on platforms such as Base, Solana, Scroll, Optimism, Arbitrum, Ethereum, and Avalanche.
