The 4 Most Dangerous Website Categories in 2025
1. Fake E-Commerce and Shopping Scam Sites
Fake shopping websites represent one of the most prevalent online threats in 2025. Research from Netcraft shows a 110% increase in fake online stores identified between August and October 2024, with over 9,000 new fraudulent domains detected in just four days during the holiday shopping season.
How they operate:
- Mimic legitimate retailers like Amazon, Nike, or luxury brands
- Offer products at impossibly low prices (70-90% off)
- Use AI-generated product descriptions copied from real sites
- Accept payment but never deliver goods
- Steal credit card information for future fraud
Red flags to watch for:
- Prices that seem too good to be true
- No physical address or contact information
- Only accepts wire transfers or cryptocurrency
- Poor grammar and spelling errors
- Recently registered domain (check WHOIS lookup)
- No SSL certificate (missing padlock icon)
Notable examples: Fake Bed Bath & Beyond sites appeared after the company's bankruptcy, fake Brooks running shoe stores, and counterfeit Tiffany & Co. websites have all been flagged by security researchers.

Frequently Asked Questions (FAQ)
How can I tell if a website is safe to buy from?
Check for HTTPS encryption (padlock icon), verify the domain matches the official brand, look for a physical address and contact information, read independent reviews on sites like Trustpilot, and use a WHOIS lookup to check when the domain was registered. New domains (less than 6 months old) selling popular products at steep discounts are major red flags.
What should I do if I accidentally visited a dangerous website?
Immediately close the browser, run a full antivirus scan, change passwords for any accounts you may have logged into, monitor your bank statements for unauthorized transactions, and consider enabling fraud alerts with your bank. If you entered payment information, contact your bank to flag or cancel the card.
Can dangerous websites infect my phone?
Yes, mobile devices are increasingly targeted. While iOS and Android have security measures, malicious websites can still attempt to install malware, steal credentials through phishing, or redirect you to premium SMS scams. Keep your phone's operating system updated and only install apps from official app stores.
Are public Wi-Fi networks more dangerous for visiting websites?
Yes, public Wi-Fi networks can be exploited by attackers to intercept your traffic through man-in-the-middle attacks. Avoid logging into banking or shopping sites on public Wi-Fi, or use a reputable VPN service to encrypt your connection.
How do I report a dangerous or scam website?
Report scam websites to: Google Safe Browsing (via the report page), the FTC at reportfraud.ftc.gov, the FBI's Internet Crime Complaint Center (IC3), and your local consumer protection agency. Reporting helps protect others from falling victim to the same scams.
Why are there so many more scam websites in 2024-2025?
