Trust Wallet Major Security Vulnerability: CISO Reveals Development Environment Under Penetration Threat

Cryptocurrency wallet security sounds the alarm again. According to the latest warning from the Chief Information Security Officer of the security firm SlowMist, the recent large-scale asset theft incident involving Trust Wallet originated from hackers gaining control over the developer environment or source code repositories. This is not a simple application vulnerability but a systemic threat involving the entire development chain. The CISO’s discovery suggests that attackers have infiltrated the internal development process, possibly injecting malicious code, leading to wallet version contamination.

Why the Development Environment Has Become a New Target

Traditional attacks often target users or servers, but an increasing number of hackers are shifting toward supply chain attacks. If the developer’s personal computer or code repository—the “upstream node”—is compromised, the impact can be catastrophic. The CISO pointed out that this incident may be a typical example of such advanced attacks—attackers contaminating the development source, making every user who downloads the update version a potential victim. Currently, some users continue to experience asset theft, indicating that malicious code is still active.

Victims Must Take Immediate Action

The security recommendations from SlowMist’s CISO are clear: users using affected versions need to disconnect from the internet immediately. Why disconnect? Because once the wallet app connects online, embedded malicious code could instantly steal private keys or seed phrases. In a fully offline state, users should prioritize exporting assets using the seed phrase and transferring them to a secure new wallet. This step must be completed before upgrading the application—upgrading blindly without transferring assets first could result in permanent loss of funds.

CISO’s Security Upgrade Guidelines

Following the security expert’s advice, the correct procedure should be: first, export the seed phrase and transfer assets while offline; second, consider upgrading the wallet application; third, reconnect to the internet and verify asset safety. This seemingly simple three-step process is actually the last line of defense in case the development chain is under attack. SlowMist’s CISO warning proves that in the blockchain ecosystem, users’ self-protection awareness and quick response capabilities are often more important than any firewall.
