What is Booking?
We flagged Booking.co as phishing. The page behavior matches a common credential-theft flow: impersonation first, urgency second, data request last.
Typical prompts on sites like this include account alerts, failed-delivery notices, or "verify now" dialogs asking for passwords, card numbers, or one-time codes. Do not submit credentials here. Open the real service in a new tab and check your account directly.

🚨
Gridinsoft blocks this website because it was classified as phishing.
booking.co should not be treated as a safe website. Gridinsoft gives it a 1/100 trust score, and multiple security vendors blacklist the domain. Avoid entering passwords, personal details, or payment data.
Why is booking.co marked "Phishing"?
Gridinsoft evaluates booking.co, focusing on limited website popularity, suspicious content indicators (Blacklisted by Security Providers, Blacklisted), hosting technology and infrastructure, SSL certificate status, website reputation across multiple databases, customer reviews from various independent platforms (200 reviews). We weigh these indicators to calculate the trust score.
Note: Automated systems are not perfect — while the evidence suggests risk, there is still a chance the site is legitimate. We recommend you check the website using detailed analysis or by contacting the company directly through verified channels.
