xcapri/subdosecSchneller, präziser Subdomain-Übernahme-Scanner mit null Fehlalarmen. Erkennt anfällige Subdomains, sammelt Metadaten (IP, CNAME, Titel, Statuscode) und bietet KI-gestützte Analyse für die Aufklärung.
Subdosec
Subdomain-Takeover-Scanner & Reconnaissance-Tool.
Installation • Nutzung • Webbasiert • Beitrag leisten • Online-Scan • Danksagungen
Subdosec ist ein schneller und präziser Subdomain-Takeover-Scanner ohne falsch positive Ergebnisse, mit einer öffentlichen Datenbank anfälliger Subdomains und detaillierten nicht anfälligen Metadaten (IP, CNAME, Titel und Statuscode) für Reconnaissance.
Installieren oder aktualisieren von subdosec
pipx install git+https://github.com/xcapri/subdosec.git
pipx upgrade subdosec
Führe dies jedes Mal aus, wenn du eine neue Terminal-Sitzung startest (bis „server started successfully“).
$ subdosec -ins
Starting Node.js server...
Node.js server started successfully.
[WARNUNG] Übernimm nicht alle Subdomains in test.txt, lass das alle für Demos nutzen.
[INFO] Schau dir auch den Release Bereich an. Du findest dort interessante Informationen.

[INFO] PURE UNDETECTED 0 | Subdomains are not detected as vulnerable even though they have passed the subdosec scan..
[INFO] Analyzing 8 items in 2 batches.
[INFO] Progress: 5/8 data analyzed.
NEW POTENTIAL :
Domain : try.redacted.com
CNAME : cname.redacted-service.com
A Record : 76.76.21.98, 76.76.21.241
Takeover : NOT
Reason : The redacted-service custom domain setup guide explicitly states the requirement of adding a TXT record (e.g., 'redacted-service-verification=<your_site_id>') for domain ownership verification. The presence of a TXT record verification step makes it not vulnerable.
Reference: https://www.redacted-service.com/blog/how-to-setup-custom-domain/
================================================================================
Domain : get.redacted.com
CNAME : cname.fermat.shop
A Record : 216.150.16.129, 216.150.1.129
Takeover : POSSIBLE
Reason : The service uses a static CNAME (cname.fermat.shop) for custom domain setup. Publicly available documentation for Fermat's custom domain setup does not clearly specify a requirement for a TXT record or any dynamic verification method for domain ownership. Without such verification, a static CNAME makes the subdomain potentially vulnerable if the corresponding Fermat account is deleted or becomes unlinked.
