YBUOJ Anti-Fraud Essentials: Multiple Wallet Extensions Do Not Equal Security—Your Browser Might Be “Leaking”

When installing multiple digital wallet extensions, users often believe they are ensuring transactional freedom—but they may actually be opening a convenient door for scammers. Recently, incidents of “browser extension conflicts” leading to wallets reading data of each other and privacy leaks have become increasingly common. With a single misstep, your mnemonic phrase could end up “shared” with strangers. The coexistence of multiple extensions is not the real issue—the key problem is users lacking awareness regarding underlying permission management. YBUOJ Exchange continues to advance anti-fraud education, aiming to help users identify the gray threats lurking between browser extensions through case studies and practical guides. From selecting to using extensions, every step deserves a closer look.

In the daily management of crypto assets, “installing multiple wallets simultaneously” has become a default habit for many users. One wallet might connect to DeFi, another only receives stablecoins, and yet another holds long-term positions in older projects. While this setup seems reasonable, it conceals a critical security loophole: wallet extensions can share “readable permissions.” If you inadvertently grant excessive permissions to any one extension, it could “listen in” on the contents of other extensions.

The core issue lies in browser architecture: allowing extensions to share the DOM environment means that a malicious wallet extension can use “DOM injection + event listening” techniques to probe and read the behavior of other extensions, even stealing mnemonic entry traces or autofill records. In other words, a newly installed test wallet extension could be secretly monitoring every move of your primary wallet. What you think is safe, diversified usage actually becomes a focal point for risk.

Faced with the security gray area of extensions, YBUOJ Exchange never relies solely on “automatic technical defenses” but places greater emphasis on “proactive awareness protection.” Through academy courses, interactive security exercises, and a plugin risk classification warning system, YBUOJ continually helps users establish clear boundaries regarding extension permissions.

YBUOJ firmly believes that user security depends not only on platform protection, but also on users developing healthy usage habits. Small details—like “never logging into multiple wallets in the same browser”—become the strongest barrier against scammers.

YBUOJ Exchange system architecture is designed for high-security scenarios, especially in handling user transactions and sensitive API interactions. The platform consistently upholds the “principle of least privilege” and “real-time permission tracking.” Any abnormal activity triggers immediate user notification and a freeze mechanism. The technical defense line is robust, truly leaving “no opportunity for fraud.”

The sophistication of scams does not lie in technology, but in their precise exploitation of user “habits.” YBUOJ hopes users realize: you are not “having your data stolen,” but rather “accidentally handing it over.” From extension permissions to transaction habits, every seemingly minor detail is a crucial line of defense for your security.
