I just pushed out version 1.9.28 of box-js to NPM (npmjs.com/package/box-js).

@SquiblydooBlog @wessorh Nice! Yeah there is also signify which tries to approximate the ms-cert store pypi.org/project/signif…. Worth a look you! I wanted something that I could deploy in win sandboxes/throw away server core workers that did real validation using win api's. think updated signtool.

@wessorh @node5 My go-to tool is osslsigncode. The main command you need is "osslsigncode verify -in <file name>" . The output isn't as clear as I would like, but it checks the CRL, checks if it is validly signed, etc.

@SquiblydooBlog This tool is probably only useful to me.. But hat tip to you :) and certgraveyard.. github.com/wmetcalf/myatg

@SquiblydooBlog Done!

@SquiblydooBlog yep I'll add some example output from mbz corpus!

@SquiblydooBlog I was also recently looking into this for keys pulled out of lsass/SSLKEYLOG for cape runs. I found a PAN writeup from years ago that claimed this was possible with tshark but couldn’t get to work so I recently baked it into my HAR/SaZ conversion tool github.com/wmetcalf/GoGoR…

In my own investigation, I downloaded the decrypted PCAP, giving me easy access to poke at and investigate the JS myself: app.any.run/tasks/73fb8a10… AnyRun published about the feature here: any.run/cybersecurity-… 3/3

Nice update to @anyrun_app that seems easy to miss: HTTPS decryption. If you look at the network traffic, click Network Threats, you can click into the analysis to see the decrypted traffic You can also just download the entire decrypted PCAP. 1/3

Security Detections MCP 3.0 is LIVE What started as a detection search MCP is now an autonomous detection engineering pipeline. Agents now run a full workflow: CTI → coverage analysis → detection generation → SIEM validation → PR staging Pipeline example: • CTI Analyst → extracts MITRE techniques from threat intel • Coverage Analyzer → checks 7k+ detections across Sigma / Splunk / KQL / Elastic • Detection Engineer → generates missing detections • Atomic Executor + SIEM Validator → tests detections • PR Stager → prepares them for review Multi-SIEM support: Splunk • Sentinel • Elastic • Sigma Open source 👇 Repo github.com/MHaggis/Securi… npm npmjs.com/package/securi… Pulse MCP listing pulsemcp.com/servers/mhaggi… Watch the full demo: youtu.be/03ZmD5cdfHI

Talk about ending the week on a high note. 🎉 With @Cisco's acquisition of @snapattackHQ now complete, we're looking forward to driving further Splunk innovation as we continue to deliver security solutions that support today's new era of SIEM. Read more here. #SplunkSecurity

@kk_onstantin No doubt! But more signal never hurts :)

@node5 And nice addition! I am afraid there will be many invalid legit ones :/

For the 2 people who probably care I took a stab at adding cert validation, SAN extraction, and missing/invalid certs. github.com/wmetcalf/rdp_h…

I'll just leave this here... github.com/wmetcalf/rdp_h…
