An increase in malicious emails impersonating US Customs and Border Protection has been observed, targeting individuals with fake Electronic System for Travel Authorization (ESTA) applications. These well-crafted emails exploit uncertainty around immigration services, urging recipients to submit new applications. The scam involves a convincing replica of the ESTA portal, collecting personal and financial information. Victims are redirected to a payment gateway, charging $88 instead of the legitimate $21 fee. The scam risks identity theft, blackmail, and financial fraud. Users are advised to verify sender addresses, inspect URLs, and access the official ESTA website directly to avoid falling victim to this sophisticated phishing scheme.
