What is F003.backblazeb2?
We flagged F003.backblazeb2.com as phishing. The page behavior matches a common credential-theft flow: impersonation first, urgency second, data request last.

Why is f003.backblazeb2.com marked "Phishing"?
Gridinsoft evaluates f003.backblazeb2.com, 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. We weigh these indicators to calculate the trust score.
