16 fake Rabby and OKX Wallet add-ons on Firefox stole recovery phrases and private keys
Socket found 16 Firefox extensions posing as Rabby Wallet (branded 'Raabby WaIIet') and OKX Wallet ('Portal WALLET'). They captured 12- or 24-word recovery phrases and private keys during the wallet import step and sent them to attacker-run Cloudflare Workers. Mozilla removed them by 5 October 2026, but Socket links them to a crypto-theft extension campaign it first saw in August 2026, so new copies may appear. No loss figure has been published; anyone who imported a seed into one of them should treat that wallet as stolen.

19 Chrome and Edge extensions hid a wallet drainer that hijacked Connect Wallet and Swap buttons
Socket found 19 Chrome and Edge extensions, from crypto price trackers and explorers to general tools like 'Enable Right Click & Copy' (70,000+ Chrome users), that loaded a modular malware framework. It drained EVM, Solana and Tron wallets by hijacking 'Connect Wallet' and 'Swap' buttons, swapped Ledger and Trezor sites for seed-phishing pages and stole exchange sessions; five extensions were bought from their original developers and turned malicious through updates. Socket thinks the campaign may date back to early 2024. Google removed the Chrome listings, but when BleepingComputer reported it on 30 August 2026 the Edge version of one was still available.

'Silent Swap' clipper hides in a fake Google Notes browser extension to swap wallet addresses
McAfee researchers found unsigned .NET and Go installers, linked to the CountLoader malware loader, that force-install a fake 'Google Notes' extension into Chromium browsers. The extension reads the clipboard and replaces copied Bitcoin, Ethereum, Bitcoin Cash, XRP, Dash and Solana addresses with attacker addresses; it finds its control server through a smart contract. Anyone who finds an unknown 'Google Notes' extension should remove it and treat anything copied while it was installed as exposed. No loss total was published.

Trojanized Trust Wallet Chrome extension v2.68 steals seed phrases; $8.5M drained from 2,520 wallets
A malicious version 2.68 of the Trust Wallet browser extension was published to the Chrome Web Store on Dec 24, 2025 with a leaked store API key, skipping the normal release review. It harvested seed phrases through a modified analytics library and sent them to metrics-trustwallet[.]com. Early reports put losses near $7M; Trust Wallet's post-mortem says about $8.5M was drained from 2,520 wallet addresses across BTC, ETH and SOL, and traces the leak to the Shai-Hulud 2.0 npm worm. The fixed v2.69 shipped on Dec 25 and Trust Wallet says it will reimburse affected users; mobile app users were not affected.
