ZachXBT Warns Trust Wallet Users After Chrome Extension Update Raises Security Concerns

Blockchain investigator ZachXBT has issued a community alert after a series of suspected crypto thefts involving Trust Wallet users, sparking renewed concerns over browser-based wallet security. According to ZachXBT, the exact root cause of the incidents remains unconfirmed. However, the timing has drawn attention, as the reports emerged shortly after Trust Wallet released an update to its Chrome extension just one day earlier.

ZachXBT has begun actively collecting wallet addresses believed to be connected to the suspected thefts and is urging affected users to come forward. As the investigation continues, the lack of an official technical explanation from Trust Wallet has fueled speculation across the crypto community, particularly around the risks associated with browser extensions.

Chrome extensions typically operate with elevated permissions, which makes them a frequent target for attackers. Security researchers have long warned that a single malicious update or a compromised dependency can expose sensitive user data, including private keys and seed phrases. In recent months, multiple high-profile cases have demonstrated how browser extensions can be weaponized against crypto users.

Cybersecurity firms have previously identified fake wallet extensions that masquerade as legitimate tools to steal recovery phrases, allowing attackers to fully recreate wallets and drain funds at a later time. Other malicious “helper” extensions have been found to subtly alter transaction details, siphoning small amounts of cryptocurrency each time a user approves a swap, often without immediate detection.

More broadly, researchers have documented campaigns in which seemingly legitimate Chrome extensions were later updated to inject malicious scripts, reroute traffic, or harvest sensitive data. While not always crypto-focused, these techniques can easily be adapted to target wallet sessions, login flows, and transaction approvals.

Against this backdrop, the Trust Wallet reports have triggered widespread concern. Users are being advised to closely review recent transactions, revoke unnecessary browser permissions, and avoid signing new transactions until more information is available. Those who suspect their wallets may be compromised are encouraged to move remaining funds to new wallets created using fresh seed phrases.

As of publication, Trust Wallet has not confirmed whether the recent Chrome extension update is directly responsible, but the situation highlights ongoing security risks tied to browser-based crypto wallets.
