Authorities across multiple regions are warning the public about a surge in scams involving impersonation of law enforcement and fraudulent messages. Scammers are using phone calls, text messages, and messaging apps like WhatsApp to deceive individuals into providing personal or financial information. Notable schemes include impersonating police officers, U.S. Customs and Border Protection agents, and toll road operators like FasTrak. Victims are often threatened with legal consequences or penalties to coerce payment or information. In one instance, scammers sent messages claiming overdue parking ticket fees in Boston, which the city confirmed were fraudulent. Bitcoin payment demands have also been reported in some scams. Additionally, WhatsApp users are being targeted through phishing links, malicious downloads, and risks associated with auto-download settings. Authorities urge the public to verify communications through official channels, avoid clicking on suspicious links, and report incidents to law enforcement or relevant agencies.
