Highlights:
Truebit Protocol exploited through pricing vulnerability to the tune of $26M.
TRU token plummets to 99.95%, reaching almost zero.
Users were recommended to cease dealing with the infected smart contract.
On January 8, 2026, DeFi protocol Truebit suffered an enormous security breach in which attackers used a bug in its Purchase smart contract to drain 8,535 ETH (~$26M) of funds. The event led to the TRU token crashing nearly completely, with security companies warning people to stay off the impacted contract as Truebit liaises with the police.
Another important one, Truebit Protocol, a decentralized finance (DeFi) platform, suffered a major security breach earlier this week. A pricing error in the Purchase smart contract (0x764C64b2A09b09Acb100B80d8c505Aa6a0302EF2) of the platform allowed hackers to mint TRU tokens nearly at no cost, depleting an unbelievable 8,535 ETH, which is equal to $26 million. This event is already listed among the largest DeFi hacks in 2026.

So, what went wrong? Truebit had a vulnerability in its Purchase contract in terms of pricing. This bug helped them to mint TRU tokens nearly free. In essence, they would be able to mint new tokens without paying the correct amount of ETH and immediately sell them to empty huge sums of crypto out of the protocol.
The secondary attack that stole approximately $250K was also smaller, and the main headline grabber was the loss of $26 million. The attackers were attempting to conceal their tracks by using some of the stolen money through Tornado Cash.
The abnormal transfer was detected by blockchain security company Cyvers Alerts in real-time as a suspicious one. Such tools as Forta also identified the exploit immediately and demonstrated the increasing significance of AI-based monitoring in securing decentralized networks. Cyvers Alerts pointed out the magnitude and the magnitude of the event and cautioned the community about the enormous potential loss.

Unsurprisingly, the TRU token suffered a huge blow. The prices went down by 99.99%, nearly to zero, and those who had held them long were stunned. The token would be trading at normal rates one minute and almost worthless the next.
The event has generated considerable furor within the crypto community, with numerous individuals noting that Truebit had never officially recorded audits of this contract, even though the company had a motto of Don’t just trust, verify. The 24-hour crypto market data now shows a 99.99% major dip, almost to 0.

Truebit’s Response: Halt and Investigate
Truebit responded promptly when they verified the intrusion. They recommended that the users should not touch the affected contacts and assured them that they would liaise with law enforcement to trace the attackers. News is being disseminated through official channels as the investigation continues.
This attack is a good reminder of the unending dangers of DeFi. Even the protocols that include slogans such as Don't just trust, verify may include unnoticed vulnerabilities. Live tracking, security checks, and responsible actions of the user are still the keys for those who work with decentralized systems.
