We also cannot say enough good things about the volunteers and MADE Studio/HackerLab in Sacramento without which this would not have been possible. Thank you for your continued support!

It's that time of year where our corporate overlords change their colors. So, we thought we'd follow along. ✨

Remember, Pride was a riot. 🧱
A rainbow-colored smiley face with crossed bones, the DEF CON logo, forms a playful skull-and-crossbones design, symbolizing hacker culture and LGBTQ+ pride. The text “DC 916” is boldly written in white graffiti-style lettering across the front. The background is purple with a dotted circular border surrounding the central graphic. This is a pride-themed logo for DC916, a local DEF CON group representing the Sacramento, CA hacker community.

DC916 has chosen their mascot, a kawaii anime girl version of Danny Devito. Prepare for lots of these!
blogs.windows.com/windowsdevel...
Satirical propaganda-style poster featuring a cartoonish character resembling Danny DeVito wearing bunny ears and holding a Tux (Linux mascot) plush in one hand and a black flag with the Tux logo in the other. Behind him, a broken Windows logo floats in a background of clouds, binary code, and open padlocks. Bold text reads: “THE FIREWALLS ARE DOWN — THE GATES ARE OPEN — INFILTRATE FREELY. WSL IS OURS NOW. CONTRIBUTE TO CHAOS. Support the Open-Source Rebellion at GitHub.” The image parodies wartime posters to promote open-source defiance.

Stylized cybersecurity propaganda poster featuring a stern blonde woman in a black bunny suit holding a dripping, corrupted computer chip glowing green. She stands against a dark, circuit-patterned background. Bold text below reads: “SANITIZE YOUR SOFTWARE — Verify your third-party drivers. Fix the system from the inside out.” The image mixes pin-up aesthetics with serious cyber hygiene messaging.

We updated our logo just a tad :)
A purple background with a circular white dotted pattern surrounding a pixelated skull and crossbones symbol in the center. The text “DC 916” is prominently displayed in bold, graffiti-style white font across the center of the image. The combination of edgy text and the skull-and-crossbones symbol suggests a rebellious or subversive theme, fitting for a digital or hacker culture aesthetic.

The UC Davis Cybersecurity Club is currently taking donations to cover competition fees and build a server lab that the university will match. Check out more info in the pic and check out the link below to donate.

A screenshot of a fundraising message from the Cyber Security Club at UC Davis. The message explains that the club has been selected to receive a $5,000 donation from the Dean’s Executive Committee within the College of Engineering during UC Davis Give Day on April 12. To unlock the funding, they need 30 donations of at least $10 before April 12. The funds will be used to build a server lab and cover competition fees, as UC Davis does not have a dedicated cybersecurity major. The message includes donation links and instructions, emphasizing the importance of ensuring donations are designated for the Cyber Security Student Chapter.

Happy Trans Day of Visibility!🏳️‍⚧️

Thank you to every trans and non-binary person for being unapologetically you.

Without your boldness, grace, wit and creativity the world would be a much less colorful and positive place.

We see you and we’re here for you. 🫶🏻

Happy #InternationalWomensDay 💜

We would like to use this day to close out our series of security and privacy flyers made by @zoe-j.bsky.social.

Help share this last flyer, Social Media Security!
Alt text: An infographic titled “Social Media Security Guide” with a pastel color scheme and pride flags (rainbow and transgender) offers security tips for social media usage. The guide is divided into four sections: 1. Account Security – Recommends enabling Multifactor Authentication (MFA) or 2-Factor Authentication (2FA) to secure accounts, avoiding the use of social media accounts to log into other services, and having separate accounts for personal and professional purposes. Encourages using blocklists to clean social media posts and manage privacy. Includes an illustration of a login screen. 2. Photos/Selfies – Advises asking for consent before taking photos of others, checking for identifiable information in photos (like license plates, mail, keys), and avoiding posting in real-time at events or near home (suggests waiting 30 minutes or using the nearest large city as a location tag). Includes an illustration of a hand holding a smartphone. 3. Messaging – Warns users to be cautious about who they talk to online, as anyone can claim expertise. Emphasizes that social media is not secure for private messaging and recommends using encrypted messaging apps like Signal. Also cautions against bots or accounts requesting money or personal information. Includes an illustration of chat bubbles. 4. More Info – Provides links to external resources such as RAINN and the National Cybersecurity Centre for more information about social media security. The Sources section credits CISA and the National Cybersecurity Alliance, linking to their resources. The guide was created by Zoe/Echo419 with support from DC916 and includes the social media handle @radicalKjax. There are small decorative icons such as a large information symbol, sparkles, and chat bubbles to emphasize the content.

Physical Security is next in our line of safety and security flyers made by @zoe-j.bsky.social!

Please share this first in a series of flyers to help spread these informational tips. 🫶
An infographic titled "Physical Security Guide" has a pastel color scheme and includes transgender and rainbow pride flags. The guide is divided into four sections: Planning/Prep – Advises creating a threat model for potential risks (e.g., disasters, power outages), tracking valuable assets, and preparing a go-bag with essentials for at least three days. Notes the importance of checking the go-bag a few times a year. Your Environment – Recommends installing alarms and cameras, using secure padlocks and deadbolts (suggested: Abus 8345 padlock, Schlage Primus deadbolt), and keeping outdoor spaces well-lit. Camera recommendations include HikVision and Reolink. Backups and Spares – Suggests keeping spares of important medications, backing up critical documents and phone numbers, and maintaining extra chargers, battery banks, water, and food. Encourages following the 3-2-1 rule for digital backups (3 copies, on 2 devices, with 1 off-site). Includes an image of a red panda with a humorous note about proper data backup. More Info – Provides links to SafeHome and HowStuffWorks for additional security resources. The sources section credits the creators and links to further reading, including resources from Deviant Ollam, USAA, and Ready.gov. Icons and images such as a checklist, a house, a globe, and an information symbol visually support the text.
