Authorities and cybersecurity experts have issued warnings about a surge in cryptocurrency scams targeting users, particularly those on macOS. Cybercriminals are distributing fake Ledger Live applications designed to steal crypto assets. Scammers employ various tactics, including fake investment platforms, fraudulent job offers, and deceptive messages via dating apps and text messages. One notable scam involves mailing counterfeit "Ledger Security" letters that demand wallet validation through QR codes, using spoofed official branding to lure victims to fraudulent websites. Law enforcement agencies emphasize the importance of verifying the authenticity of such requests to avoid falling victim to these schemes.
