The trick
A site or pop-up claims your browser or wallet needs an urgent update and offers a download. The file is malware that can steal keys or hijack your clipboard.
Why it works
Update prompts feel routine, and urgency discourages scrutiny. The fake prompt mimics real update UI closely.
Staying safe
Update only through official channels — your browser own settings or the wallet official site. Never install software from a pop-up or a link in a chat.
