As explained in a dashboard created on Dune platform by Scam Sniffer, out of all wallets at risk, only 7,860 addresses managed to revoke all approvals at LaunchZone. Meanwhile, 75,564 BNB Chain (BSC) wallets are still at risk.
Analysts explained that hackers managed to drain liquidity thanks to the vulnerabilty in Bscex SwapX, a smart contract that served as an exchange instrument on LaunchZone. A sample of the code of the potential attack’s design has also been shared by researchers.
They reiterated that all wallets that interacted with the hacked contracts (the addresses of four such contracts are indicated by Scam Sniffer) should remove their approvals by automated revoke services or manually. All vulnerable contracts were deployed back in January-October 2021.
$7.8 million in users’ funds already stolen
Despite the fact that the global crypto community was informed of the necessity to revoke the approvals, by press time, hackers managed to steal $7,792,137 in crypto equivalent.
The team of LaunchZone confirmed the hacker attack. It appeared to be fatal for the protocol: yesterday, on March 26, 2023, its website stopped operating.

In March, the team organized a compensation program for affected users.
