CoinVoice has learned that, according to Cointelegraph, the security company Koi Security has disclosed that the cybercrime group GreedyBear has stolen over $1 million in cryptocurrency through hundreds of fake wallet extensions, malware, and scam websites.

Koi Security discovered that this group has released over 150 malicious extensions in the Firefox browser app store, disguised as cryptocurrency wallets such as MetaMask, TronLink, Exodus, and Rabby Wallet. The attackers used Extension Hollowing technology, first creating a legitimate extension that passes market review, then transforming it into malicious software. [Original link]
