Jupiter, a decentralized exchange aggregator, has issued a warning about a new fraudulent browser extension that targets Solana users.
The extension, known as “Bull Checker,” poses as a tool to view memecoin holders but secretly steals funds from users’ wallets.
According to Jupiter’s research released on August 20, this malicious extension, available on Google Chrome, was designed to bypass detection. Once installed, it manipulates transactions to redirect funds from users’ wallets while appearing legitimate.
The extension’s request for extensive permissions, including “read and write” access, is a major red flag, as legitimate tools typically require only “read-only” permissions. Despite this warning, many users continued to use the extension, leading to stolen funds.
Jupiter confirmed that major Solana DApps and wallets are not compromised. This discovery comes in the wake of a $1 million exploit at the Cypher Protocol and a separate incident where over $100,000 was stolen from a Phantom Wallet during a presale event.
The U.S. Department of Justice has sentenced Dwayne Golden, 57, of Pennsylvania to 97 months in prison for orchestrating a fraudulent crypto investment scheme that stole over $40 million from investors.
The first half of 2025 has become the most damaging six-month period in crypto history, with over $2.1 billion stolen across 75+ separate incidents, according to new data.
A new breed of cyber-attack is sweeping through crypto media, exploiting site pop-ups and wallet-connect prompts instead of smart-contract bugs.
CoinMarketCap, one of the most widely used crypto data tracking platforms, is reportedly facing a front-end security breach, with multiple users encountering a suspicious prompt to verify their wallets.
