TREE NEWS update: SlowMist alerted on September 7 that two attackers are replicating the recent Notional Finance exploit on the BSC chain. They have completed preparatory steps, creating malicious fCash positions using the same vulnerability pattern. The attack is not fully executed yet, as the positions await maturity. Once matured, the attackers could settle and drain assets from protocols. SlowMist urges affected projects to take mitigation measures before positions expire.
SlowMist: Two Attackers Replicate Notional Finance Exploit on BSC
This development signals that exploit playbooks are being reused across chains with minimal delay, underscoring how quickly vulnerability patterns propagate after disclosure. The fact that the attackers have staged positions but not yet executed highlights a narrow window for affected protocols to act, making the maturity timeline the critical variable. The open question is whether the broader DeFi ecosystem will treat post-mortem details as urgent cross-chain warnings, given that replication appears cheaper than original discovery. For projects sharing similar architecture, this is a reminder that mitigation must be proactive rather than reactive.
