It's Kinda Like Dune: A Look Into the Shai-Hulud Malware

Speaker: Draggr

Shai-Hulud is a term given by the Fremen of Arrakis to the gargantuan sandworms that inhabits the dunes of Arrakis in Frank Hebert's Dune. Shai-Hulud is also a self-propogating npm worm that has infected tens of thousands of GitHub repositories and affected hundreds of users, with the latest iteration of the malware spotted as of April 2026.

In this presentation, we will look at the findings posted by established malware researchers and highlight their observations in an entertaining way.

Next Month · November Meeting

The 12 Talks of Christmas (November 19th)

Speaker: You and 11 others!

Got something cool to share with the cybersecurity community? This is your chance.

12 Talks for Christmas is a rapid-fire round robin featuring 12 speakers, 5 minutes each. Pick any cybersecurity, hacking, privacy, hardware, programming, or technical topic you want and take the stage.

The rules are simple: you get 5 minutes. That’s it. When the timer hits zero, you're done and the next speaker is up. No overtime, no “one more slide,” no 30-minute conference talk hiding inside a five-minute slot. We will lovingly usher you off the stage.

This event is meant to be low-pressure and fun, so priority will be given to new and first-time speakers. You do not need to be an expert, professional presenter, or conference veteran. If you learned something interesting, built something weird, broke something spectacularly, discovered a useful tool, or just have a technical rabbit hole you want to share, we want to hear about it.

12 speakers. 12 topics. 5 minutes each.

Bring an idea. Bring a few slides if you want. Just make sure you can beat the clock.
