Do you enjoy guzzling real-time TLS certificate allocations, but don't want to use a third-party service (crt.sh, CertStream, etc.)? Drink straight from the Certificate Transparency log firehose using ctail:
$ go run github.com/hdm/ctail@latest -f -m '^autodiscover\.'
A PSA for why you should probably not use Postman (it can leak secrets to them): https://anonymousdata.medium.com/postman-is-logging-all-your-secrets-and-environment-variables-9c316e92d424
Hello from BSides San Francisco! I'm excited to speak at 1:30pm in the AMC IMAX today. If you'd like to catch up afterwards, I'll be at the runZero booth first and at the City View lounge later. If you couldn't make the trip, the streaming links are live at https://www.youtube.com/@BSidesSF/streams
Hope to you see you there!
A few quick notes on the Erlang OTP SSHd RCE (CVE-2025-32433):
1. Cisco confirmed that ConfD and NSO products are affected (ports 830, 2022, and 2024 versus 22)
2. Signatures looking for clear-text channel open and exec calls will miss exploits that deliver the same payloads after the key exchange.
3. If you find a machine in your environment and can't disable the service, running the exploit with the payload `ssh:stop().` will shut down the SSH service temporarily.

Hoping this helps someone else. When setting up a Supermicro AS-1015A-MT 1U w/H13SAE-MF & Ryzen processor, trying to boot Debian 12 or Proxmox 8.3 media results in "Welcome to Grub" and the machine stalling, sometimes also showing "error: no such device: /.disk/info". The fix? Disconnect the display (!) or wait 30-45 minutes for the installer to show up otherwise. The IPMI KVM works fine for setup. Thanks to mirk_daniel on the Proxmox forums for the tip! https://forum.proxmox.com/threads/installation-error-grub-error-disk-info-proxmox-ve-8-3.159131/
Jacob Sandum posted a detailed and well-written PoC for the IngressNightmare (CVE-2025-1974 ) vulnerability found in the Kubernetes ingress-nginx Admission Controller by Wiz (Woogle!). If you are looking for a quick way to reproduce the issue or validate detection and mitigation, take a look:
https://github.com/sandumjacob/IngressNightmare-POCs/blob/main/CVE-2025-1974/README.md
Today, Wiz (Woogle?) released an advisory detailing an attack chain they’ve dubbed IngressNightmare, which, if left exposed and unpatched, can be exploited to achieve remote code execution by unauthenticated attackers. The advisory, covering five separate vulnerabilities, was published after a brief embargo period, once the Kubernetes folks got their patches together.
