Sei ecosystem-based Filament DEX exploited for $572K

Filament, a decentralized exchange built on the SEI blockchain, was affected by a major self-employed feat.

According to the post-hack declaration of the shared platform on X, the attackers took advantage of the platform command books system to steal around $ 572,000.

The Filament Dex feat occurred between 00:00 and 4:00 UTC on April 6, during which the attackers used large orders and self-liquidations on several accounts to manipulate prices and withdraw funds. Before the incident, Filament held about $ 680,000 in user deposits.

Shortly after detecting the violation, Filament stopped all the exchanges and withdrawals to stop new losses. They have since launched a complete investigation, teaming up with the police and the blockchain security experts to follow the stolen funds.

The attackers moved the funds through the symbiosis bridge, then in the exchanges, mainly a fixed float. Portfolio addresses and transactions linked to the incident were shared with the authorities and forensic teams to help recover the funds.

Filament offered to operate a bonus of 10%, around $ 57,000, if they return the rest of the money. The offer is open to negotiations, as long as the attacker cooperates fully.

The co-founder of Filament, known only under the name of Abhitej, also published an update on X, affirming that the team examines the newspapers minute by minute, working with the authorities and prepares a plan to return what remains for suppliers of liquidity. A full report will soon be provided, as well as a process for users assigned in the Pool of the platform to recover some of their assets.

This attack adds to what has already been the worst year never recorded for cryptographic hacks. According to the Q1 2025 of Immunofi report$ 1.64 billion was stolen in the first quarter of only 2025. The DEFI protocols lost $ 106.8 million in 38 incidents, while centralized platforms have only seen two violations, but with much larger losses totaling $ 1.5 billion.

March 26, hyperliquid (THRESHING)) incurred A loss of $ 10.63 million, also due to a self-employed incident. OAK Security Managing Director, Dr. Jan Philipp Fritsche, warned That many DEFI platforms are at risk of self-liquidation exploits due to foreseeable failures in commercial mechanisms.
