This host impersonates Allegro Lokalnie, the Polish local classifieds service, by placing the brand name as a subdomain in front of a random-looking .biz domain. It targets people buying or selling items through the marketplace. PhishDestroy first recorded it on 2026-09-11, and on 2026-10-19 it was still online and serving content. The page title reads "Web Server's Default Page", while our classification is impersonation phishing.
How the scam works
Fake Allegro Lokalnie pages usually reach victims through a chat message from a supposed buyer or seller. The message claims a payment has been made or a delivery booked, then links to a page that copies the marketplace's look. The victim is told to "confirm" or "receive" the funds by entering card details, online banking credentials or one-time codes. Those details let the attackers drain the account or authorise payments, while no real transaction exists.
Evidence
Sixteen of 89 VirusTotal engines flagged the domain as of 2026-09-23. They include BitDefender, ESET, Fortinet, G-Data, Forcepoint ThreatSeeker, alphaMountain.ai, Chong Lua Dao and Google Safe Browsing. Google Safe Browsing separately classifies it as social engineering, so Chrome, Firefox and Safari users should see a warning. Spamhaus DBL lists it as a phishing domain, which helps mail filters block the link. PhishDestroy also blocklists it.
Infrastructure
The base domain was registered on 2026-03-07 through Global Domain Group LLC, about six months before we detected it. It may have been held in reserve or rotated through other subdomains first. Traffic goes through Cloudflare's network in the US, which hides the origin server behind a shared proxy address. A free Let's Encrypt certificate supplies the padlock, so the padlock does not show that the site is genuine.
What to do
If you entered card details on this page, call your bank immediately, block the card and dispute any unfamiliar charges. If you typed in banking or Allegro login credentials or SMS codes, change those passwords from a clean device, turn on two-factor authentication and review recent account activity. Real Allegro Lokalnie transactions are handled inside the official app or site, so treat any chat link that asks you to "accept a payment" as fraud. Defenders should block the full 17391j36y1.biz domain, not just this subdomain, and should report the page to Allegro and 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.
