SlowMist2026-10-08 01:18:59SlowMist’s Cos Warns of Bookmark Phishing Attacks Targeting FOMO Web UsersSlowMist researcher Cos warned on Oct. 8 that a bookmark-based phishing attack targeting FOMO’s web interface has begun to appear. According to the alert, the phishing page tricks users into completing a fake human verification step, then asks them to drag malicious JavaScript code into the browser’s bookmarks bar and save it as a bookmark. Once the victim clicks that bookmark two to three times, an attacker can hijack a previously logged-in FOMO account and immediately steal the crypto assets held in it. The warning focuses on a client-side attack flow that abuses browser bookmarks rather than a normal wallet signature prompt, making it a notable security risk for users accessing FOMO through the web.20
SlowMist2026-10-08 01:05:18SlowMist’s Cos Warns of Bookmark Phishing Attacks Targeting FOMO Web UsersSlowMist researcher Cos has warned that bookmark-based phishing attacks aimed at FOMO’s web interface are now being observed, according to a newsflash published by Odaily. The attack uses a fake human-verification prompt to trick users into dragging malicious JavaScript code into their browser bookmarks and saving it as a bookmark. Once the victim clicks that bookmark two to three times, an attacker can hijack a previously logged-in FOMO account. The warning says crypto assets held in the compromised account can then be stolen immediately. The alert focuses on a browser-side attack path rather than a direct wallet exploit, with the malicious code delivered through a deceptive webpage and activated through repeated bookmark clicks. Users of the FOMO web version are being urged to stay alert to this type of phishing setup.30
