- In a striking development, the Bull Checker Chrome extension has reportedly compromised the safety of DeFi users.
- The extension illegally transferred tokens to unauthorized wallets without the owner’s consent.
- Jupiter [JUP], a well-known exchange aggregator, disclosed the discovery of this malicious browser extension targeting Solana’s [SOL] DeFi users.
Discover how a rogue Chrome extension is posing a significant threat to Solana’s DeFi ecosystem. Read more to understand the impact and necessary precautions.
Revelation of the Malicious Browser Extension
Recently, Jupiter [JUP] released a critical report bringing to light a malicious browser extension that targets Solana’s [SOL] DeFi ecosystem. Known as the Bull Checker Chrome extension, it allowed users to interact with decentralized applications (dApps) under false pretenses of normalcy, transferring tokens to an unknown wallet upon completion of transactions without users’ consent.
The Modus Operandi of Bull Checker
The Bull Checker extension posed as a regular tool for interacting with dApps. However, it secretly carried out unauthorized token transfers upon transaction completions. This deceptive functionality went undetected until users noticed missing tokens post-completion of transactions. Jupiter highlighted that users were convinced to install Bull Checker, presumably due to recommendations from certain community members, such as a Reddit account named Solana_ OG.
Immediate Actions and Precautions
Following this alarming discovery, Jupiter promptly advised the community to uninstall Bull Checker and other extensions with unverified extensive permissions. Users were warned to remain vigilant and cautious when dealing with any third-party extensions, as the risk of unauthorized transactions is substantial.

Impact on Solana Ecosystem
This incident adds to the woes of Solana, which has been witnessing significant outflows. According to Coinshare, Solana experienced an outflow amounting to $39 million over the past week. The reduced trading volume of memecoins within the Solana ecosystem further exacerbates the network’s financial situation.
Solana’s Financial Metrics
Data from DefiLlama indicates a steep decline in Solana’s net flow, which currently stands at -0.22 million. This negative net flow is indicative of dwindling demand for Solana’s ETPs and memecoins, contributing to the overall turmoil faced by the network.
