Filament Finance DEX on Sei Ecosystem Suffers $572K Exploit

Highlights:

• Filament Finance lost $572,000 from a security compromise.
• The hackers initiated unauthorized fund withdrawals via price manipulation on the platform’s order book.
• The DEX platform has partnered with blockchain security experts to aid asset recovery.

Filament Finance, a DEX platform on the Sei ecosystem, suffered a security compromise that drained roughly $572,000 from the exchange. The DEX platform confirmed the hack on its verified X handle via an April 6 tweet. According to the exchange, the hackers exploited large order placements and self-liquidation mechanisms. This enabled the scammers to steal funds via price manipulation on the platform’s order book.

Filament Finance reported the hack lasted four hours, between 12:00 AM UTC and 4:00 AM UTC on April 6. The DEX platform also noted it had about $680,000 in total user deposits before the compromise, implying that the exchange was left with $108,000 after the exploit.

Recovery Efforts

In its tweet, Filament Finance outlined its fund recovery efforts. First, the DEX platform secured its protocol by halting trading operations and withdrawals. Secondly, it reached out to leading blockchain forensic firms and DeFi partners to investigate the hack.

In addition, Filament Finance tracked the movement of the stolen funds. The DEX platform said the hackers first moved most of the funds through Symbiosis Bridge before depositing them into exchanges, especially Fixed Float. Filament Finance added that it had submitted all wallet addresses linked to the stolen funds to relevant blockchain security authorities. This will facilitate tracing and asset seizure, limiting the platform’s loss.
