Stay Alert: Malicious Chrome Extension Targeting DeFi Users
Recently, a dangerous Chrome Extension known as “Bull Checker” has been preying on DeFi enthusiasts, resulting in the loss of their tokens over the past week.
The Discovery and Investigation by Jupiter Exchange:
- Jupiter Exchange was the first to uncover this threat, alerting the community about the extension’s sinister activities, particularly targeting Solana users.
- An in-depth probe by Jupiter revealed that Bull Checker appeared innocent initially, allowing users to engage with dApps normally.
- However, the true intentions of the extension were insidious, as it had the capability to transfer tokens to another wallet without the user’s knowledge.
The Modus Operandi of Bull Checker:
- After installation, the extension monitored user interactions with dApps and covertly altered transactions sent to wallets.
- Despite these modifications, the outcome displayed to users seemed typical and did not raise immediate suspicion.
- Jupiter reassured users that the vulnerabilities did not stem from the dApps themselves but were caused by the malicious extension.
The Read-Only Nature of Bull Checker:
Jupiter emphasized that while Bull Checker claimed to be ‘read-only’ for viewing memecoin holders, it had no valid reason to access or modify data on all websites.
Discouraged by Red Flags:
- Despite warnings, some users continued to install Bull Checker, disregarding the potential risks associated with the extension.
- An anonymous Reddit account under the alias “Solana_OG” actively promoted the extension, targeting individuals interested in memecoin trading.
- Jupiter advised users to exercise caution and scrutinize any extension before installation to mitigate potential threats.
Bull Checker was a ‘Read-Only’ Extension
Jupiter identified the malicious chrome extension as ‘read-only,’ supposedly designed for viewing memecoin holders, raising concerns about its unnecessary data access across websites.
