xcapri/subdosecScanner veloce e preciso per la rilevazione di takeover di sottodomini, con zero falsi positivi. Rileva sottodomini vulnerabili, raccoglie metadati (IP, CNAME, titolo, codice di stato) e fornisce un'analisi assistita dall'IA per la ricognizione.
Subdosec
Scanner e strumento di ricognizione per takeover di sottodomini.
Installazione • Utilizzo • Basato sul web • Contributo • Scansione online • Riconoscimenti
Subdosec è uno scanner per takeover di sottodomini veloce e accurato, senza falsi positivi, con un database pubblico di sottodomini vulnerabili e metadati dettagliati non vulnerabili (IP, CNAME, titolo e codice di stato) per la ricognizione.
Installa o aggiorna subdosec
pipx install git+https://github.com/xcapri/subdosec.git
pipx upgrade subdosec
Quindi esegui questo comando ogni volta che avvii una nuova sessione terminale (finché non viene visualizzato “server started successfully”).
$ subdosec -ins
Starting Node.js server...
Node.js server started successfully.
[AVVISO] Non effettuare il takeover di tutti i sottodomini in test.txt, lascia che tutti lo usino per le demo.
[INFO] Controlla anche la sezione Release. Puoi trovare informazioni interessanti.

Subdomain takeover scanner.
options:
-h, --help show this help message and exit
-mode {private,public}
Mode of operation (private/public)
-initkey INITKEY Initialize the API key
-vo VULN Only: Hide UNDETECT messages
-pe Print Error: When there are problems detecting your target
-ins Prepar node & start server
-pf PF Private Fingerprint: uses your local fingerprint. Example: -pf /path/to/tko.json
-subfng SUBFNG Submit fingerprint: submit local fingerprint to admin. Example: -subfng localfinger.json
-lf LF Fingerprint lock: to focus on one or multiple fingerprints. (-lf github.io,surge.sh) and leave this arg to scan all fingerprints
-sfid To view all available fingerprint ids.
-ks To shut down the server node if you want to not use subdosec for a long time.
-o O Save result locally to the specified path. Example: -o /path/to/dir
-su Skip undetect will not stored to server (https://subdosec.vulnshot.com/result/undetected)
-lu LU Undetec stored localy to the specified path. Example: -lu /path/to/dir
-lm Local Mode: Save vuln and undetect to default inside tools directory (auto -su)
-uf Update Fingerprint
-unai UNAI Analyze undetected subdomains using AI. Example: -unai /path/to/undetect.json
-v, --verbose Show progress count (e.g. [1/10])
-t THREADS, --threads THREADS
Number of threads to use for scanning (default: 10)

[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.
