I just released Flareprox 🔥 A Cloudflare based Fireprox alternative that allows you to route HTTP traffic through Cloudflare, to gain mostly unique IP Addresses, to avoid detection and blocks.

1997: Nmap was first released as a simple port scanner via an article in issue 51 of Phrack magazine which included the source code. That's right - 28 years of Nmap!

Can you spot the difference on these two responses? 🤔 Just found out a little trick to leverage region-specific CNAME records to enumerate S3 buckets at a massive scale (up to ~500k per second), without ever touching them via HTTP. celes.in/posts/s3_dns_enum

If you want to integrate PugRecon with your tools, you can now use our new API. It's available at pugrecon.com/. Also, our subdomains dataset grew and sits currently at 2.5 billion. Lastly, I plan on developing niche features and make them available. More on that soon.

Just shipped a major refactor for PugDNS 🐾! Overhauled the transmission logic with retries & domain tracking, added a BPF worker pool, and enhanced eBPF observability. Enjoy blazing fast DNS queries with AF_XDP + eBPF for your mass DNS recon! github.com/c3l3si4n/pugdns/

I've just released my proof-of-concept tool called pugDNS. It's an experimental high-performance DNS bruteforcer built with AF_XDP. It's up to 3x faster than massdns, and 30x faster than dnsx. github.com/c3l3si4n/pugdns

born to mass resolve, forced to answer abuse complaints 🙏 pugrecon now is back to resolving and adding more domains! we briefly had a issue with @ClouDNS where they were complaining about a few hundred queries per second 🙄 guess how i fixed it
