• Announcing PSP's cryptographic hardware offload at scale is now open source. What happens when the NSA draws a smiley face on your network map? You spend a decade perfecting encryption that you can offload to smart NICs so that all traffic is encrypted in transit. I wonder where the next smiley face will be drawn...
• Confluence Server and Data Center - CVE-2022-26134 - Critical severity unauthenticated remote code execution vulnerability. "Atlassian has been made aware of current active exploitation of a critical severity unauthenticated remote code execution vulnerability in Confluence Data Center and Server. The OGNL injection vulnerability allows an unauthenticated user to execute arbitrary code on a Confluence Server or Data Center instance."
• Information Security Controls: Cybersecurity Items. The US joins Europe with its own "Wassenaar Arrangement" rule by the Industry and Security Bureau. TLDR don't sell cyber capabilities to Country Group D.

Techniques and Write-ups

• Abusing CVE-2022-26923 Through SOCKS5 on a Mythic C2 Agent. This post explores the AD CS vulnerability but uses Mythic an an Apollo agent with SOCKS forwarding to pull it off. Nice practical usage example!
• From open redirect to RCE in one week. This is a wild ride through a series of strange small bugs that result in full RCE. Web app hackers take note.
• Technical Advisory - Multiple Vulnerabilities in U-Boot (CVE-2022-30790, CVE-2022-30552). This one is for the embedded device hackers (and chromebook hackers).
• Managed Identity Attack Paths, Part 1: Automation Accounts. Azure Automation Accounts, Logic Apps, and Function Apps all use "Managed Identity assignments" which allows scripts to authenticate as a specific Service Principle. These services can be used by an attacker to leak their JWT which can be used to authenticate outside the context of the Authentication Account.
• DeepPass — Finding Passwords With Deep Learning. It's starting to feel like Will is lining up a career change into data science, but as long as he keeps the red team angle I'm here for it. Here he trains a model (DeepPass) to recognize passwords in arbitrary documents. How long before this is repackaged and sold as "AI/ML deep learning information disclosure hunter 9000" at RSA?
• LSASS needs an IV. Spoiler: It doesn't really need an IV if you can guess a few characters of a password. Interesting deep dive into the (poor?) cryptographic decisions in LSASS.
• Enumeration and lateral movement in GCP environments. Lateral movement is more fun in the cloud.

Tools and Exploits

• COM-Hunter - COM Hijacking voodoo.
• VoightKampff - Beating Google ReCaptcha and the funCaptcha using AWS Rekognition.
• Nidhogg Nidhogg is an all-in-one simple to use rootkit for red teams.

New to Me and Miscellaneous

This section is for news, techniques, write-ups, tools, and off-topic items that weren't released last week but are new to me. Perhaps you missed them too!

• The Surreal Case of a C.I.A. Hacker's Revenge. I haven't read this one yet but its on my list.
