hardclosesoftware.com presents itself as "hardclose — construction ERP by TC Software LLC," a business software product aimed at construction firms. PhishDestroy classifies it as an impersonation phishing page that borrows this product identity to win the trust of visitors. We first flagged it on 2026-10-04. As of 2026-10-19 the site was still online and serving content. The page title shows a construction software vendor, and our classification is impersonation phishing.
How the scam works
Impersonation pages copy the name, look and wording of a real or plausible company so visitors treat them as an official portal. A visitor expecting a product login, demo signup or download is asked for work credentials, contact details or other sensitive input, and that information goes to the operators. Because the domain also appears on MetaMask and SEAL blocklists, visitors may be pushed toward a wallet connection or signature request. A malicious approval can let attackers move tokens out of the connected wallet.
Evidence
On 2026-10-07, 12 of 92 VirusTotal engines flagged the domain. They include alphaMountain.ai, BitDefender, CRDF, CyRadar, Forcepoint ThreatSeeker, Fortinet, G-Data and Gridinsoft. Spamhaus lists it in its DBL under the phishing category. MetaMask and SEAL list it alongside PhishDestroy, which means wallet-focused defenders have independently judged it dangerous. Four AlienVault OTX threat pulses reference it as well.
Infrastructure
The domain was registered on 2026-09-10, just 24 days before we detected it. That short gap is typical of a site set up for a campaign rather than a long-running business. It is registered through Cloudflare, Inc. and sits behind Cloudflare's network in the US, which hides the origin server. Its TLS certificate from Google Trust Services (WE1) is issued automatically, so the browser padlock says nothing about who runs the site.
What to do
If you entered a password on this site, change it right away. Do the same on any service where you reused it, and turn on app-based 2FA. If you downloaded anything presented as hardclose software, do not run it, and scan the device. If you connected a wallet or signed a request, revoke the approvals granted to unfamiliar contracts with a token-approval checker, and move remaining funds to a fresh wallet. Defenders should block the domain at DNS and the mail gateway. They should also warn construction and finance staff about lookalike ERP sites and report the domain to Cloudflare's abuse channel.

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.

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
