Bug bounty researcher details common IIS server misconfigurations and discovery tactics that expose sensitive Windows web infrastructure

The article is a hands-on guide for finding and assessing Microsoft IIS servers during bug bounty research, covering discovery via Shodan, Google dorks, and fingerprinting. It highlights recurring IIS weaknesses such as internal IP leaks, tilde enumeration, exposed web.config files, path traversal, DLL exposure, authentication bypass tricks, and WAF evasion.

The piece underscores how legacy and misconfigured IIS deployments remain a durable attack surface despite years of awareness. Its emphasis on automation, search indexes, and LLM-assisted reconnaissance reflects a broader trend: attackers and researchers are combining old web-server flaws with modern tooling to scale discovery faster.
