In plain words

Subdomain Enumeration CLI is a command-line tool designed for developers and security researchers who need to discover subdomains associated with a target domain. It automates the process of identifying subdomains by querying various data sources and techniques. The tool is particularly useful for reconnaissance during penetration testing, security audits, and general domain mapping tasks. It runs locally via command line, making it suitable for users comfortable with terminal environments.

  • Fast subdomain enumerator written in Rust2022 · github.com · ▲23

    Hello! I'm learning Rust and also information security, so what better way to learn than to put a tool together practicing both skills? I've tried to use a couple of different tools for subdomain enumeration (part of the Discovery-party when it comes to penetration testing), but none of them were very fast, even if the DNS resolver I pointed them towards is, so I wrote my own tool that leverages concurrency to check a lot of subdomains, fast! It's written in Rust, main parts being using Tokio and async_channels, and I think it works good enough for a first release. I wanted to get recursive…

    hey guys, wanted to show one of my side projects i just made public. the idea is basically another osint tool for pentesters and bug bounty hunters. it watches certificate transparency logs and checks newly-seen domains for exposed stuff like .env files, open .git dirs, config files, db dumps and so on, and puts whatever it finds into a searchable db. you just search a domain (or part of one) and see what's exposed. it's read-only and free. one thing i've been thinking about adding is a way to register for certain keywords and get notified when something new shows up for that search. would…

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
