Domain Hunter – Checks Expired Domains For Categorization/Reputation And Archive.org History To Determine Good Candidates For Phishing And C2 Domain Names

Domain name selection is an important aspect of preparation for penetration tests and especially Red Team engagements. Commonly, domains that were used previously for benign purposes and were properly categorized can be purchased for only a few dollars. Such domains can allow a team to bypass reputation based web filters and network egress restrictions for phishing and C2 related tasks.This Python based tool was written to quickly query the Expireddomains.net search engine for expired/available domains with a previous history of use. It then optionally queries for domain reputation against services like Symantec WebPulse (BlueCoat), IBM X-Force, and Cisco Talos. The primary tool output is a timestamped HTML table style report.Changes5 October 2018 Fixed logic for filtering domains with desirable categorizations. Previously, some error conditions weren’t filtered and would result in domains without a valid categorization making it into the final list.4 October 2018 Tweaked parsing logicFixed changes parsed columns indexes17 September 2018 Fixed Symantec WebPulse Site Review parsing errors caused by service updates18 May 2018 Add –alexa switch to control Alexa ranked site filtering16 May 2018 Update queries to increase probability of quickly finding a domain available for instant purchase. Previously, many reported domains had an “In Auction" or "Make an Offer" status. New criteria: .com|.net|.org + Alexa Ranked + Available for PurchaseImproved logic to filter out uncategorized and some potentially undesirable domain categorizations in the final text table and HTML outputRemoved unnecessary columns from HTML report6 May 2018 Fixed expired domains parsing when performing a keyword searchMinor HTML and text table output updatesFiltered reputation checks to only execute for .COM, .ORG, and .NET domains and removed check for Archive.org records when performing a default or keyword search.
