    • Interpreting Audit Records for Teams Meeting Recordings (Again) Three years ago, I wrote a script to analyze the audit records generated for Teams meeting recordings. Then things changed in terms of how the audit records were generated and how the Search-UnifiedAuditLog cmdlet returns audit search results. All of which meant that considerable work was needed to revamp (rewrite) the script. Maybe you need to check any script that uses the Search-UnifiedAuditLog cmdlet too?

  • PuTTY vulnerability vuln-p521-bias

    Jump

  • If I understand correctly, the signatures generated by PuTTY aren’t perfectly random, so if someone got a hold of a bunch of keys from a server, they could figure out the pattern. It takes about 60 keys. This affects not just PuTTY, but also FileZilla, WinSCP, TortoiseGit, and TortoiseSVN.

    In other words if you have NIST P-521 keys, or any others using 521-bit ECDSA, you should revoke them and generate new key pairs. After you update your software.

  • I installed some security cameras around my house and set up Shinobi using an old PC. Unfortunately the PC is too old to use the built-in detectors in Shinobi. So, I took my first dive into playing around with some image detectors.

    I wrote some python to download the daily recording from old PC to a newer one with a 3080 GPU. Then checks the videos for people. It will then trim the videos to only include times were there are people in frame. It cut my the storage requirements by over 95%.

  • Biggest things I'm seeing is CVE-2023-21709 for Exchange requires a PowerShell script to be run after patching. Also, CVE-2023-29328/29330 for Teams affect all devices (Windows, Mac, iOS, and Android).

  • What book would you recommend to explain to someone what you do for a living?

    Jump

  • The book I wrote. When I first talked with the publisher he asked, "what skills would you look for in someone who wants to do your job?" And that's the premise I stuck with writing it.

  • Datalookup: Deep nested data filtering library

    Jump

  • Interesting. As someone who mainly deals in PowerShell, this is very similar to the Where-Object clause and could save me some headaches when I need to work in Python.

  • "If you are happy and you know it", and what it does to your Spotify statistics.

    Jump

  • From personal experience, it seems like things outside of your normal listening don't affect too much. At least in my case, my daughter making me play the Encanto soundtrack 250,000 times hasn't affected my weekly or daily playlists.

  • That's pretty similar with what happened with me and the train. Kept getting random drops from a plant. I went out to investigate and everything tested perfect and the network was staying up. That was until a freight train rolled by. Turns out AT&T had run the line by shoving a piece of PVC through the gravel between two cross-ties, then running the cable through it.

  • I've actually had an excavator take out my network. I've also had networks taken out by forklift, train, and a semi-truck towing three other semi-trucks.

  • Basically every Windows sysadmin is indebted to Mark Russinovich and SysInternals. Fortunetly, PowerToys has come a long way because I'm pretty sure sysinternals haven't been updated since Windows XP.
