Small bug bounty writeup from one of my findings from the past - even back then having a carefully crafted list of non resolving starbucks hostnames was essential (shameless ad: argosdns.io). Writeup: argosdns.io/blog/how-i-got-i… Background of hackerone.com/reports/500468

ICYMI: I created an LLM-powered tool to detect CVEs before they're even published - and it's now powering vulnerabilityspoileralert.co…. This is a simple GitHub page statically generated using vulnerability-spoiler-alert-action. Check out the backtest findings at github.com/spaceraccoon/vuln… and let me know what you think the hit rate is! I'm running this open-source vulnerability intelligence project using a personal API token, but maybe @AnthropicAI... or @OpenAI might want to support this? 👀

Very interesting read, can't wait to try some MCP pentest🫡
I wrote about Hackbots on the @Hacker0x01 site! It covers what they are, where they're at now, and most importantly where it's all heading 😊 I hope you'll check it out! Link in first reply.

Tired of waiting hours for cert.sh to catch new domains? @G0LDEN_infosec built Gungnir—a tool that scrapes CT logs in real time. See new domains within seconds of cert creation. Full talk on YouTube → youtu.be/yQQ92XAWfGY #BugBounty #Recon #BugBountyVillage

Recently I was targeted by an extremely sophisticated phishing attack, and I want to highlight it here. It exploits a vulnerability in Google's infrastructure, and given their refusal to fix it, we're likely to see it a lot more. Here's the email I got:

Si no hubiera sido por la convocatoria de septiembre, yo no habría acabado mi carrera, tres años seguidos fui y gracias a eso saqué la carrera en 4. Es una vergüenza que no se haya preguntado la opinión del propio alumnado que va a hacer estos exámenes.
El Consejo de Gobierno @unizar ha aprobado hoy el calendario académico 2022-2023 con el adelanto de la convocatoria de septiembre a finales de junio y principios de julio. Así se armoniza el calendario con el resto de etapas educativas: y se equipara al resto de universidades.

For those that are trying to keep up, the log4j JNDI injection is probably pre-auth RCE on approx ~90% of your Java apps. You wanna patch this one.

The latest update where @duosec swapped the spots for approve/deny for their MFA push is a killer due to my muscle memory.

De las peores cosas que le podrían pasar a Polonia. Un país que podría ser grande en Europa haciéndose la zancadilla a si mismo.
