How do I gather open source intelligence for CTF challenges?

Open source intelligence for CTF challenges involves collecting and analyzing public data using DNS reconnaissance, social media analysis, and reverse image search. This skill automates gathering from platforms like Shodan and Wayback Machine to extract hidden flags.

Can I use Shodan and Censys for DNS reconnaissance in a CTF?

Yes, you can use Shodan and Censys for DNS reconnaissance. This skill integrates these dependencies to perform in-depth web and DNS record analysis, helping identify target infrastructure and vulnerabilities during CTF competitions.

What is the best way to perform reverse image search and geolocation for OSINT?

The best way to perform reverse image search and geolocation is to use an automated skill that processes image metadata and cross-references visual data. This allows you to accurately identify physical locations from media files.

Do I need Python 3 and bash to run OSINT lookups?

Yes, you need Python 3 and bash to run OSINT lookups. This skill requires a filesystem-based agent with internet access to execute scripts and query APIs like VirusTotal and IPinfo for effective information gathering.

How does username enumeration work with platforms like GitHub and Telegram?

Username enumeration works by querying platforms like GitHub and Telegram to extract profile data and activity history. This skill uses tools like WhatsMyName and Namechk to correlate identities across multiple social media networks.
