Trust Wallet Chrome Extension Breach: $7M Stolen Through Hidden Malicious Script That Could Evade Detection

The security world erupted after Trust Wallet disabled its Chrome extension version 2.68 on December 25, 2025, following a critical incident that compromised user wallets across multiple blockchain networks. The emergency update came after researchers and victims reported coordinated fund drains tied to the flawed version, with confirmed losses reaching approximately $7 million.

The Attack Timeline and Scale

Users began reporting stolen assets shortly after December 24, when version 2.68 rolled out to roughly 1 million Chrome extension users. The vulnerability created a narrow but catastrophic window—victims who imported or entered their seed phrases while running the compromised version found their assets drained to unknown addresses within hours.

Trust Wallet released patch version 2.69 the same day the incident gained public visibility, addressing the root cause. The company later confirmed that mobile users and other extension versions remained unaffected. However, the damage was already done for those who had interacted with 2.68 during the vulnerable period.

Technical Breakdown: How the Script Evade Detection Systems

Security researchers dissecting version 2.68 uncovered obfuscated JavaScript logic embedded within the extension bundle, including references to a suspicious file labeled “4482.js.” This malicious script was designed to intercept wallet secrets and transmit them to external servers, effectively harvesting private keys from unsuspecting users.

What made this attack particularly dangerous was the sophistication of how the malicious code attempted to evade both automated security reviews and runtime detection. The script employed obfuscation techniques that research suggests can degrade the effectiveness of static machine-learning detection systems over time—a phenomenon known as “concept drift” in academic literature.

The attack vector specifically targeted user inputs at the most sensitive point in the signing flow. Browser extensions sit at a critical intersection between web interfaces and cryptographic operations, meaning any compromise directly threatens the same data users rely on to verify transactions and manage assets.

Who Was Vulnerable and What They Should Do Now

The highest-risk group consisted of users who imported or entered a seed phrase after installing 2.68—a seed phrase serves as the master key to all current and future addresses derived from it, making it the crown jewel of wallet security.

For affected users, simply updating to 2.69 is insufficient. The patch prevents future exploitation but does not retroactively protect already-exposed credentials. Standard incident response requires:

• Treat the compromised seed as permanently unsafe and create a new wallet using a fresh seed phrase
• Move all funds to addresses generated from the new seed
• Revoke token approvals wherever feasible to prevent additional drains
• Verify system integrity before reusing any device that processed the compromised phrase

These steps demand significant operational effort from retail users, including re-establishing positions across multiple chains and applications. Gas costs and bridging risks add another layer of complexity to the recovery process.

Trust Wallet also warned of secondary scams leveraging the incident. Attackers launched copycat “fix” domains attempting to trick panicked users into revealing recovery phrases under the guise of providing solutions.

Market Impact and TWT Price Movement

Trust Wallet Token (TWT) showed mixed market reaction to the breach announcement. Current pricing reflects measured concern rather than panic selling:

• Current price: $0.88
• 24-hour change: -1.92%
• Intraday range: $0.86–$0.90

The relatively stable price action suggests the market is pricing in Trust Wallet’s swift response and commitment to reimburse affected users, though long-term confidence hinges on transparency and comprehensive post-incident disclosure.

Broader Implications for Crypto Infrastructure

This incident reignites fundamental questions about how consumer-facing crypto software manages secrets on general-purpose devices. The distribution method—through official app stores with review processes—raises uncomfortable truths about the limitations of automated security screening and the need for:

• Reproducible builds to enable independent verification
• Split-key signing architectures that distribute trust
• Clearer rollback mechanisms when emergency patches are needed
• Enhanced browser extension reviews that catch obfuscated malicious code before deployment

The breach underscores that even trusted custodian solutions remain vulnerable when they operate within the constraints of general-purpose computing platforms.

What Happens Next: The Uncertainty Range

Loss accounting remains fluid. The $7 million confirmed by Trust Wallet may shift based on:

• Delayed victim reporting over the coming weeks
• Additional attack vectors that investigators may discover
• Cross-chain tracking as stolen funds move through swap routes and exchanges
• Effectiveness of copycat prevention efforts

Industry observers anticipate the loss range could evolve as follows over the next 2–8 weeks:

The Path Forward

Trust Wallet’s commitment to refund all affected users represents a significant financial responsibility but demonstrates confidence in its investigation. The company’s transparency will determine whether the incident becomes a cautionary tale or a catalyst for industry-wide security improvements.

For users, the decision tree is straightforward: Did you enter a seed phrase while 2.68 was active? If yes, rotate immediately. If no, updating to 2.69 from the official Chrome Web Store resolves the immediate threat. Either way, Trust Wallet’s guidance is clear—disable 2.68 and upgrade now.
