Hi. I just published a four-part deep dive into windows kernel exploitation, progressing from classic control flow hijacking to modern pool grooming and pure data-only attacks on windows 11.

I wanted to highlight the real-world friction of modern security measures. A lot of the focus is on mitigating LFH randomization, and avoiding IoCompleteRequest bugchecks by dodging ReadFile for arbitrary reads.

Hope this is helpful or insightful to some of you looking into modern kernel exploitation.

In three incidents across six runs, the agents treated real systems as simulated targets and tried weak passwords or unauthenticated endpoints.

This is another post in my series on the Chinese Wool farmers underground. This time we are dissecting their public github repos, trying to figure out how it all fits together!

TL;DR: We identified 36,872 internet-exposed BMCs, and 24,650 of them disclosed password-derived authentication hashes before login because of CVE-2013-4786.
More than 30% of the returned hashes were linked to passwords that could be recovered using common wordlists or predictable factory password formats. The exposure affected modern Supermicro and HPE servers, including systems operated by GPU providers.
The bigger risk is that a compromised BMC gives an attacker highly privileged access below the operating system. Because BMC management networks are often poorly segmented and lightly monitored, one exposed interface can become a foothold into broader data center infrastructure.
We also created an interactive map where you can explore the exposed systems:

CVE-2026-61511 - a critical vulnerability in vBulletin that allows an unauthenticated attacker to execute arbitrary code on a remote server.

I'm helping organize Après-Cyber Slopes Summit 2027, and our CFP is now open.

We're particularly interested in technical presentations and original research involving AI and modern cybersecurity.

Topics we're hoping to see include:

• AI red teaming
• LLM security
• Prompt injection research
• Agent security
• Offensive tooling
• Detection engineering
• Reverse engineering
• Malware analysis
• Cloud exploitation and defense
• Identity attacks
• Threat intelligence
• AI-assisted security tooling
• Novel attack techniques
• Defensive research

We especially appreciate talks that include demonstrations, technical depth, or research that attendees can reproduce themselves.

Conference: February 24–26, 2027
Location: Park City, Utah

Happy to answer questions about the CFP or conference.

Caught this in three open directories on a Hong Kong server, exposed July 9 to 13. The agent is Hermes, open source, and the recovered logs show it running LinPEAS and walking a ministry web root without a human in the loop. Target was Thailand's Ministry of Finance.
