NahamSec Highlights the Importance of Reconnaissance in Hacking

In this video, NahamSec emphasizes the crucial importance of reconnaissance (recon) in the field of hacking. He explains that reconnaissance can be approached in two main ways: either by broadening the scope of investigation to discover many subdomains and micro-applications, or by focusing on a single application to uncover specific vulnerabilities. NahamSec also clarifies that reconnaissance is not synonymous with automation, the latter involving the creation of custom tools to scan for specific bugs on the internet.

NahamSec then presents several reconnaissance sources that he frequently uses. The first is Project Discovery Chaos, a project that actively monitors various companies and provides lists of subdomains for public bug bounty programs. Although this source is free, it requires an API key to access all features via the command line interface (CLI). NahamSec demonstrates how to use Chaos to quickly obtain thousands of subdomains without needing other tools.

Another important source is C99.nl, which NahamSec prefers for its reliability and affordability. For just $25 per year, C99 offers access to its API and a wealth of useful data for reconnaissance. NahamSec shows how to use C99's API to obtain subdomains and information on Cloudflare servers, which is particularly useful for bug bounty programs.

For a broad and targeted approach, NahamSec recommends Waymore, a tool that combines multiple sources such as VirusTotal, Wayback Machine, and Common Crawl to provide an overview of URLs and responses associated with a domain. He explains how to use Waymore to obtain detailed information on subdomains and parameters, which can be very useful for identifying specific vulnerabilities.

Finally, NahamSec introduces Alien Vault, a source that provides contextual information on assets and third-party services used by a company. He shows how to use Alien Vault's API to obtain information on subdomains and API routes, which can sometimes reveal API keys or other sensitive information.

In conclusion, NahamSec emphasizes that combining these different reconnaissance sources can greatly enhance the efficiency of vulnerability research. He encourages viewers to explore these tools and integrate them into their own hacking methodology.
