Truebit’s TRU token faced a dramatic decline on Thursday after the protocol revealed a significant security incident linked to one of its Ethereum smart contracts. On-chain trackers indicated that the amount stolen was around 8,535 ETH, approximately valued at $26 million based on recent market prices.

Truebit reported that the incident involved “one or more malicious actors” and confirmed it was in contact with law enforcement, actively implementing “all available measures” to address the issue.

Investigators monitoring the protocol estimated the theft at 8,535 ETH, which corresponded to a total value of about $26.6 million at the time of the report.

The news of the hack spread rapidly through the trading community. Typically, issues with smart contracts can create widespread disturbances in liquidity, confidence, and prices across various exchanges.

Exploit Details: Smart Contract Bug Leads to Free Token Minting

Truebit aims to mitigate one of blockchain technology’s main challenges: the high costs associated with on-chain computation. The protocol allows applications to verify complex computations without executing every step on Ethereum, thereby enabling heavy computation tasks to occur off-chain while maintaining on-chain verification for advanced smart contracts and computing applications.

The protocol has flagged malicious activity associated with its "Truebit Protocol: Purchase" contract and advised users to refrain from interacting with the address until further notice.

There has yet to be a full technical analysis of the incident. However, initial on-chain assessments pointed to a failure in the pricing logic of the getPurchasePrice function, where unusually high mint requests allegedly yielded a zero cost. This flaw enabled attackers to mint tokens freely and circulate them through a bonding curve, effectively draining the ETH reserves.

Attackers Wash Stolen Ether Through Tornado Cash

Following the theft, transaction trails indicated a significant effort to clean up the stolen funds. The attackers consolidated the stolen ETH into a main address and routed a large portion through Tornado Cash, a move typically indicative of premeditated action rather than a haphazard occurrence.

The market reacted swiftly to this news. On-chain analysis revealed that the TRU token's value plummeted over 99%, with data from Nansen showing a drop from around $0.16 to approximately $0.0000000029.

This incident feeds into a broader discourse on security within the cryptocurrency sector. PeckShield recently reported that the total losses from crypto hacks and exploits decreased from $194.2 million in November to about $76 million in December, marking a 60% drop. Nevertheless, the ecosystem continues to grapple with constant threats from protocol vulnerabilities and user-targeted scams.

PeckShield's analysis highlighted a $50 million loss from an address poisoning incident and another approximately $27.3 million loss related to a key leak in a multisig wallet.

Truebit has not disclosed its plans for remediation, nor is it clear what specific factors triggered the exploit or whether user funds remain at risk.
