Exploiting default Active Directory permissions to create malicious, dormant DNS records for future hostnames. This might help hijacking new machine records upon network join for subsequent Kerberos or NTLM relay attacks. A post by Giulio Pierantoni. Source: medium.com/@offsecdeer/adidn… #redteam #blueteam

Super cool research from my colleague Shai Laron on new attack paths to Active Directory that can lead to full domain takeover 😜 . It was presented at Black Hat and he will be speaking again at DEF CON this weekend. Don't miss this 💪 : semperis.com/blog/identity-c…

A little gitbook I wrote to mainly help myself learn the ins and out of the protocol to the level of MS-KILE/RFC4120. Others might also find it helpful and valuable in learning the protocol to a deep level without needing to read dry open specs thattotallyrealmyth.gitbook.…

Onelogon: Taking over Active Directory Accounts via Netlogon🔑 We analyzed Netlogon, bypassed the Zerologon patch, resulting in a full auth bypass. An attacker can leverage this to compromise computer accounts, or even the entire AD. Non-standard config must be present tho 🧵

NetHack is one of the most complex and longest-lived open source programs ever written, and after 46 years, v5.0 shipped today. nethack.org/common/index.htm… And ... it is a VERY cool large codebase to work with in the LLM era.

I am excited to release the seventh article in the Exploiting Reversing Series (ERS). Titled “Exploitation Techniques | CVE-2024-30085 (part 01)” this 119-page technical guide offers a comprehensive roadmap for vulnerability exploitation: exploitreversing.com/2026/03… Key features of this edition: [+] Dual Exploit Strategies: Two distinct exploit versions using Token Stealing and I/O Ring techniques. [+] Exploit ALPC + PreviousMode Flip + Token Stealing: elevation of privilege of a regular user to SYSTEM. [+] Exploit ALPC + Pipes + I/O Ring: elevation of privilege of a regular user to SYSTEM. [+] Solid Reliability: Two complete working and stable exploits, including an improved cleanup stage. [+] Optimized Exploit Logic: Significant refinements to the codebase and technical execution for better stability and predictability. The article guides you through the two distinct techniques for exploiting the CVE-2024-30085 Heap Buffer Overflow vulnerability. I would like to thank Ilfak Guilfanov (@ilfak on X) and Hex-Rays SA (@HexRaysSA on X) for their constant and uninterrupted support, which has helped me write these articles over time. I hope this serves as a definitive resource for your research. If you find it helpful, please feel free to share it or reach out with your feedback! Enjoy your reading and have an excellent day.

Full ADWS support landed with --use-adws --obfuscate flag works surprisingly well without breaking the xml github.com/aniqfakhrul/power…

Unauthenticated Remote Code Execution (RCE) on Domain Controllers (DC). It does not get worse than that. Probably will be included in #ransomware campaigns. Any technical analysis of CVE-2024-49112 published? CC: @gentilkiwi @harmj0y @_wald0

I'm in a secret hacker chat and we all got old so we're talking about sleep apnea testing and hair transplants instead of exploits
