Another Monday. Another week of… endless emails, annoying meetings, and oh look, a three-headed monkey behind you! Now that we have your attention, we can unveil the agenda for #RomHack2025 romhack.io/romhack-confer… #infosec #securityconference
I just published a blog post where I try to explain and demystify Kerberos relay attacks. I hope it’s a good and comprehensive starting point for anyone looking to learn more about this topic. ➡️decoder.cloud/2025/04/24/fro…
Microsoft has discovered post-compromise exploitation of CVE 2025-29824, a zero-day elevation of privilege vulnerability in Windows Common Log File System (CLFS), against a small number of targets. msft.it/6019qIVV9
NTLM relay is still a major threat and is now even easier to abuse. We just added new NTLM relay edges to BloodHound to help defenders fix and attackers think in graphs. Read my detailed post - the most comprehensive guide on NTLM relay & the new edges: ghst.ly/4lv3E31
We (me + @2igosha) have discovered a new Google Chrome 0-day that is being used in targeted attacks to deliver sophisticated spyware 🔥🔥🔥. It was just fixed as CVE-2025-2783 and we are revealing the first details about it and “Operation ForumTroll” securelist.com/operation-foru…
Check out our new blog post!
new #elastic defend rules out : - PPL bypass via ComDotNetExploit - Execution via Windows-Run (trending delivery method ITW) github.com/elastic/protec…
Hey, we should really switch from NTLM to something like Kerberos, yet another good reason, right? cc @ShitSecure @splinter_code 😂🤣
KrbRelayEx-RPC tool is out! 🎉 Intercepts ISystemActivator requests, extracts Kerberos AP-REQ & dynamic port bindings and relays the AP-REQ to access SMB shares or HTTP ADCS, all fully transparent to the victim ;) github.com/decoder-it/Krb…
Great work! few detection points: - registry change "HKLM\\SOFTWARE\\Classes\\CLSID\\{0BE35203-8F91-11CE-9DE3-00AA004BB851}\\TreatAs\\" - WaaSMedicSvc loading CLR (result of .NET execution in the context) - Impersonation as Trusted Installer.

Another simple standalone tool for creating machine accounts with custom password in Windows AD github.com/decoder-it/New…
Skiing with @cybersaiyanIT sticker is priceless 😀

🚀 #RomHack 2025 #callforpapers is OPEN! Are you a #cybersecurity pro with a passion for sharing knowledge? This is your chance to take the stage at #RomHack2025 📩 Apply now: cfp.romhack.io/romhack-2025/c… #InfoSec #hackercommunity
Multi-Platform FINALDRAFT malware targeting government orgs. Outlook drafts for C2. We published a deep dive on the malware and another on the campaign. Great research by the team! elastic.co/security-labs/… elastic.co/security-labs/…
Notes from the Field: My journey in trying to change Windows password in the most complex way, purely for fun, very little profit, but definitely a fun challenge! More details here ➡️decoder.cloud/2025/02/11/cha…
NTLM Relaying with DCOM cross-session activation over an external OXID resolver. This variant has the advantage over regular RemotePotato0 that all connections are established from victim to attacker and none in opposite direction. Credits go to @MrAle_98.
@splinter_code Are you sure they fixed? 🤨 This is the latest w11 insider canary ....
Two new posts from @tiraniddo today: googleprojectzero.blogspot.com/2025/01/window… on reviving a memory trapping primitive from his 2021 post. googleprojectzero.blogspot.com/2025/01/window… where he shares a bug class and demonstrates how you can get a COM object trapped in a more privileged process. Happy Reading! 📚
