Decentralized lending platform Polter Finance suffered a devastating exploit on the Fantom blockchain, primarily wiping out most of its property.
The breach, found early Sunday, concerned the manipulation of the platform’s token pricing mechanisms, leaving its customers in shock.
The attacker started by funneling funds by Twister Money, an Ethereum-based coin mixer that conceals the origin of funds. These property had been then bridged—transferred from Ethereum to the Fantom community—the place the exploit was executed.
As soon as the breach was recognized, Polter Finance took instant motion by pausing its platform to include the injury and notified key bridge operators.
The pseudonymous founding father of Polter Finance, referred to as “Whichghost,” filed a police report in Singapore following the breach. The hack resulted in losses exceeding 16.1 million SGD (roughly $12 million USD).
The newly deployed good contract on the platform was exploited, inflicting unauthorized transactions to empty consumer property, says the report. The founder additionally reported private losses of $223,219.
Whereas the police report claims complete losses of round $12 million, different reviews from web3 safety corporations recommend the precise quantity stolen was nearer to $7 million.
In line with DeFi Llama information, Polter Finance’s TVL was roughly $9.7 million earlier than the assault, indicating substantial losses.
In a press release on X (previously Twitter), the staff wrote, ““We recognized wallets concerned and traced it to Binance. We’re nonetheless investigating the character of the exploit. We’re within the processing of contacting the Authorities.”
The platform additionally despatched an on-chain message to the attacker, saying the staff can be keen to barter with out pursuing authorized motion if the stolen funds are returned.
Web3 safety consultants suppose the basis reason behind the exploit was linked to a worth manipulation assault utilizing oracles—exterior information feeds that platforms use to find out token costs.
Sensible contract audit agency QuillAudits shared their findings with Decrypt which exhibits the vulnerability was tied with how Polter Finance calculated the worth of the SpookySwap BOO token.
“The value of the SpookySwap BOO token within the lending pool was decided by the spot worth from the SpookySwap v3 pool and v2 pair; calculated primarily based on the token steadiness ratio within the pool,” QuillAudits informed Decrypt.
By artificially rising the value of the BOO token, the hacker may deposit a really small quantity (simply 1 BOO token) and withdraw a a lot bigger quantity of different property, successfully draining the platform of its funds.
“This case exemplifies a traditional Oracle manipulation exploit. The BOO token worth is manipulated by the attacker utilizing a flash mortgage to artificially inflate the BOO token’s worth,” Hakan Unal, Senior Blockchain Scientist at Cyvers Ai, informed Decrypt.
Polter Finance introduced it has since colllaborated with the Safety Alliance Info Sharing and Evaluation Middle (SEAL-ISAC) to trace down the hacker.
This incident provides to the rising record of safety breaches within the crypto sector. The entire quantity misplaced to the exploits has surpassed $2 billion in 2024 alone, with code vulnerabilities leading to $39.6 million in losses over 44 incidents, per a latest Certik report.
