You're accessing a secure settings, please provide your password to continue. Password Authentication required!
Why it was flagged
The site presents a 'Mail Authentication' portal requesting a password to access secure settings, which is a common tactic for credential theft. The domain 'security-server-stat-a728.bolt.host' does not align with any legitimate email service provider, indicating impersonation.
Automated reading of the page content, not a manual finding.
security-server-stat-a728.bolt.host is an impersonation phishing page dressed up as a generic webmail sign-in, titled "PORTAL - example.com Mail Authentication". It targets ordinary email users and corporate mailbox holders rather than any single provider. PhishDestroy first flagged it on 2026-10-07. As of 2026-10-19 the site was still online and serving its phishing content.
How the scam works
Victims usually arrive through an email warning that their mailbox needs re-verification, is nearly full, or has pending messages. The link leads to this "Mail Authentication" portal, which asks for an email address and password. Its brand-neutral look, with a placeholder domain in the title, lets one page pass as almost any organization's login. Whatever the victim types goes to the operator. A stolen mailbox can then be used to reset passwords on other services, including exchange and wallet accounts, and to send fresh phishing from a trusted address.
Evidence
On 2026-10-07, 10 of 92 VirusTotal engines flagged the page, including Kaspersky, Fortinet, Netcraft, Forcepoint ThreatSeeker, G-Data, Emsisoft, alphaMountain.ai and LevelBlue. That count is modest, but it comes from several unrelated vendors that reached the same verdict on their own. urlscan.io rated the page malicious and matched it to a generic email login brand. It also appears on the PhishFeed blocklist alongside PhishDestroy.
Infrastructure
The hostname is a subdomain on bolt.host, a shared app-hosting zone. Its 2024-11-14 registration date, through Cloudflare, Inc., applies to that parent domain, so domain age says little about when this particular page went up. Traffic is served from Cloudflare's network in the US, which hides the origin server. The Google Trust Services certificate gives the page a padlock, but that shows only that the connection is encrypted, not that the site is legitimate.
What to do
If you entered a password on this page, change it immediately on the real email service and on any other account that shares it. Turn on app-based or hardware-key two-factor authentication. Check your mailbox for forwarding rules, unfamiliar recovery addresses and active sessions you don't recognize, and sign out of all sessions. Then review accounts that can be recovered through that inbox, especially exchange and wallet services. Defenders should block the hostname, search mail logs for messages linking to it, and reset credentials for any user who clicked through.
For the registrable domain bolt.host behind this subdomain, the registrar above operates under an ICANN accreditation agreement. The links below provide the official fee schedule and current DNS abuse compliance guidance.
Accreditation is a contract, not a safety certification.
RAA §3.18 establishes abuse-contact and handling requirements. This report can document stored outbound notices and later technical observations; it does not by itself establish receipt, investigation, remediation, or contractual non-compliance.

Availability, content, DNS and registration are independent evidence layers. NXDOMAIN, an unreachable origin or missing content alone does not prove registrar action. A registrar or provider is credited only when a direct technical marker identifies that actor. Report causality is shown separately.

联邦调查局（FBI）指南
Keep original emails, receipts, messages and screenshots in a secure place. A factual timeline helps the receiving authority understand what happened. IC3 evidence guidance ↗
Payment records — if you paid, save the receipt, amount, date, payment provider and recipient details.
Your bank or payment provider — contact its fraud team promptly through official contact details if money or card information was exposed.
当地警方 — 即使无法立即采取行动，也能留下正式记录
A report is not a guarantee of recovery or investigation, but prompt, accurate transaction data can help authorities and service providers trace the incident.
How do phishing scams typically work?
虚假网站 — 与正规网站完全一致的克隆网站，仅域名略有改动
猪的屠宰 — 通过Telegram/WhatsApp/交友软件花数周时间建立信任，随后钱被骗走
退款诈骗 — fraudsters pose as recovery agents and demand upfront fees. Never share a seed phrase or pay before independently verifying the provider
