• The extension secretly gathers user seed phrases and sends them to attackers via tiny Sui-based transactions, allowing theft.
• No user reviews, little branding, grammatical errors, and no official website indicate the extension’s illegitimacy.
• Research extensions and developers thoroughly, keep seed phrases private, and regularly check wallet transactions to avoid scams.

A​‍​‌‍​‍‌​‍​‌‍​‍‌ fake Chrome extension called “Safery: Ethereum Wallet” that seemed like a safe Ethereum wallet was located on the Chrome Web Store. But it is not. The compromised Chrome extension quietly harvests the most secure seed phrases from users’ accounts, thereby putting those accounts at risk. The extension tries to conceal the activity from the users with a quite functional and user-friendly ​‍​‌‍​‍‌​‍​‌‍​‍‌interface.

Modus Operandi

After the chrome extension either makes a new wallet or imports an old one, the seed phrase is sent secretly to the attacker by means of a tiny sui-based transaction. Once the attacker has the wallet, they are free to carry out any kind of theft. What makes it hard to detect the chrome extension’s malicious activity is that it uses synthetic Sui-style addresses.

Red Flags and Warning Signs

Among many other things, the lack of user reviews for the Chrome extension, minimal branding, and grammatical errors all point to the fact that this is not a legitimate extension. Moreover, there is no official website for the extension.

Contacting the developer through a Gmail account that he uses for all correspondence also makes one wonder. Accordingly, the users should be very cautious when dealing with extensions that behave in such a manner.

Protecting Yourself from Scam Extensions

A user who is determined to never become a victim of a similar attack should not install any blockchain platform or tool without conducting research first. A significant part of this is to check the legitimacy of both the extension and the developer. Besides that, users can also practice good security hygiene by making sure their seed phrases are kept private and regularly checking their wallet transactions.
