A brand-new harmful internet browser extension called the “Bull Checker” is apparently targeting Solana users on Reddit by masquerading as a meme coin tracker.
This extension averts detection systems and has actually drained pipes Solana users’ wallets.
In the previous week, Jupiter’s pseudonymous creator, Meow, reported that a couple of Solana DeFi users experienced unapproved token drains pipes. Through a comprehensive examination with partners, they traced the problem to “Bull Checker,” which had actually been targeting users on numerous Solana-related subreddits.
This extension enabled users to connect generally with decentralized apps (dApps), however it covertly moved tokens to unapproved wallets upon deal conclusion. Jupiter’s creator worried that no vulnerabilities were discovered in the dApps or wallets themselves.

Preferably, such an extension needs to not need authorization to check out or compose information on all sites, which ought to have raised issues for users. Regardless of this, numerous users continued to set up and utilize it.
As soon as set up, Bull Checker waits till a user connects with a basic dApp on its main domain, then modifies the deal before it is signed by the wallet. The customized deal still appears “typical” in the simulation, hiding its real intent as a drainer.
While looking into the Chrome extension, Jupiter’s creator likewise found that it was promoted by a confidential Reddit account, “Solana_OG.” This specific appeared to target users wanting to trade meme coins and tempted them to download the extension.

They even more went on to include that extensions that ask for substantial approvals, such as the capability to check out and customize all site information, ought to be treated with severe care.
“While we have actually determined one destructive extension, there may still be other harmful extensions out there.

If you believe an extension includes malware, especially if they have both “check out” and “modification” consents, uninstall it right away.”
