Stored registration data identifies NameSilo as the registrar. PhishDestroy maintains separate registrar investigations; that broader material is contextual and is not an independent detection for this domain.
The domain pdfworker.online has been identified as a generic phishing domain with no specific brand impersonation or drainer kit detected. Analysis indicates that this domain was being used to deceive users and potentially steal sensitive information.
Infrastructure analysis reveals that pdfworker.online has a VirusTotal score of 18/95, indicating a significant level of detection by security vendors. The domain is registered through NameSilo, LLC, and resolves to the IP address 188.114.96.3, which is located in the United States and is part of AS13335 Cloudflare, Inc. The domain was created on April 15, 2026, and is currently listed on one security blocklist. It is also blocked by the PhishDestroy system. The SSL certificate is issued by Let's Encrypt (YE1).
The domain is currently offline, which reduces the immediate risk to potential victims. However, the domain's registration and IP infrastructure should be monitored for any signs of reactivation. Organizations and individuals are advised to update their security policies to block this domain and educate users about the risks of generic phishing attacks. The elevated risk level and the presence on security blocklists suggest that the domain may have been part of a broader phishing campaign, and further investigation is recommended to identify any related infrastructure or activities.
For this gTLD, 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.
Saved certificate metadata. Certificate dates without a timezone are shown as stored. Transport encryption does not establish that the site is trustworthy.

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.
