Introducing Cyllex - Advanced APT Emulation Framework.
cyllex.io/
I've been working on this for a while, pouring real effort and love into it. Not a quick release, I'm going step by step, building something solid. Some of the current features include:
▸ APT database with real-world campaign emulation
▸ Cross-platform agents via binary patching
▸ Agent, Agentless (WinRM/SSH), and Cloud execution
▸ Direct shell access for real-time interaction
▸ Interactive MITRE ATT&CK detection coverage tracking
▸ Calendar-based campaign scheduling
▸ Webhook notifications (Slack, Teams...)
▸ Robust TTPs: On-Premise (Windows/Linux), Cloud, and Containers
I'll be sharing updates as the project evolves. Thank you, and happy new year!

Congrats to @killa who solved stealmybitcoin.com hours ago but I screwed up which key went on the server (the flag was a root wallet WIF instead of the branch WIF).

New research from @GrayHatKiller: NTLM relay to domain controllers with LDAP signing enforced. Patch your DCs. 👇

1/2
LDAP signing was supposed to stop NTLM relay to LDAP. I found a way to relay coerced SMB auth to a DC with LDAP signing and channel binding enforced.
Patched in October.

I wrote up a way to defeat enforced SMB signing for relay.
It abuses a documented SMB re-authentication behavior.
I'm surely missing nuance and prior art. Corrections welcome.

Microsoft patched PetitPotam in their latest update, EFSRPC now validates shares locally, killing WebDAV coercion
💀
Added a check to NetExec’s enum_cve module to detect if a host already has the fix (CVE-2026-102217), so you can quickly spot what’s still exploitable 🔥

🦛🦛🦛Microsoft patched PetitPotam this October: EFSR now only resolves local paths. This means WebDAV to LDAP Coercion is fixed!
Remaining methods for clients are WSP (coercing SMB) and PrinterBug (coercing RPC), but both cannot be relayed to LDAP 💀💀💀

APT Encyclopedia updated: every claim in the 62 profiles checked against its source, wrong citations fixed or removed, all changes logged. Work continues on the extraction agents so only claims a primary source supports make it in.

I used Opus 5.5 on max and GPT-6 Astra for 5 days straight and I reversed engineered Elastic Security and extracted all the rules. I made them available here:

You’re welcome.

This is a really interesting APT tradecraft write-up.
Cisco Talos uncovered UAT-11587, a China-nexus activity cluster targeting government and policy organizations across Asia with a previously undocumented Rust backdoor called Antino.
The interesting part: its native C2 runs entirely through Microsoft 365.
• Outlook + OneDrive used as dead drops
• Microsoft Graph for C2
• Shell + PowerShell execution
• File upload/download
• In-memory shellcode execution
• Persistence
• 5-stage infection chain
• Cloudflare infrastructure for staging + tracking
• ~350 compromised endpoints across 8 countries observed
Talos also documented tailored spear-phishing, fake Gmail attachment widgets and government/policy-themed decoys.
Excellent research by @CiscoTalos / @ashl3y_shen .

Released cldap_ping.py: AD user enum over real UDP cLDAP, plus anonymous rootDSE recon over TCP.
cLDAP tooling commonly runs the ping over TCP, which Event 5156 catches. Sending it over UDP leaves only netlogon.log (per Part 6). 😈

When I started ipurple.team/ two years ago, my goal was to give SOC teams practical detection opportunities across some of the most modern adversarial techniques.
So far, I’ve documented 25 techniques, and every article includes:
✅ SIGMA Rules
✅ Sysmon Configs
✅ Threat Hunting Queries
If you work in Purple Teaming, Detection Engineering, Threat Hunting, or even the Red Team space, and you want your MITRE ATT&CK coverage to look like the example below, dive into the articles, start emulating, and begin hunting.
If you know that someone else in your network will benefit, feel free to repost.

New writeup: Patch-Gap Zero-Days: BlueMoon.
Five China-nexus clusters chained two V8 patch-gap bugs (CVE-2026-85046, CVE-2026-87491) to one Windows ALPC LPE zero-day (CVE-2026-85880) against Chrome on Windows.
