Warning: Chrome Extension “Bull Checker” Targeting Solana Users
A recent threat has emerged in the form of a Chrome extension called “Bull Checker” that is specifically targeting Solana users. The extension, which was promoted as a tool for viewing memecoin holders, has been identified by Jupiter, a decentralized exchange aggregator on the Solana blockchain, as malicious.
How “Bull Checker” Works
Here’s an overview of how the “Bull Checker” Chrome extension operates:
- The extension bypasses standard security checks and drains users’ wallets without their knowledge.
- It requests “read and write” permissions, which is a warning sign for a wallet-checking extension.
- Despite appearing normal during transaction simulations, the extension functions as a wallet drainer.
- It was promoted on Reddit, targeting Solana memecoin traders.
The Risks Involved
The deceptive nature of the “Bull Checker” Chrome extension poses significant risks to Solana users:
- It can pass Solana simulation checks, making it difficult to detect its malicious intent.
- Users who installed the extension experienced unauthorized transfers of their tokens.
- Legitimate wallet-checking extensions typically only require “read-only” permissions, making the request for “read and write” permissions a cause for concern.
Actions to Take
If you are a Solana user, it is crucial to take immediate action to protect your assets:
- Remove the “Bull Checker” extension from your browser to prevent any further unauthorized transfers.
- Exercise caution when installing new extensions and verify their legitimacy before granting extensive permissions.
- Avoid falling for recommendations or promotions from unknown sources, as scammers may use social engineering tactics to gain access to your wallet.
Hot Take: Stay Vigilant Against Malicious Extensions
As the cryptocurrency space continues to evolve, the threat of malicious actors targeting users is ever-present. By staying informed and proactive in safeguarding your assets, you can minimize the risks associated with using digital platforms and extensions.
