Ground Rules

• Saf(er) Space

  • We DO NOT tolerate demeaning/harmful language or behavior

  • Don't pressure or question someone discussing their experience/threat model/situation

  • Consent: Ask before helping someone out!

• Keep it constructive!

• Share the space!

  • Stack!  Raise your hand, we'll queue speakers

• Photo/Video- Ask for approval!

• Identify yourself if you are a...

  • reporter, researcher, or law enforcement

Warmup

What are some things you consider when you...

• Are out late at night?
• Leave home for a few days?
• Aren't allowed to have your phone?
• Are attending a protest?

Holistic Approach

Balance > Purity            Growing > Finishing

Threat Modeling

1. What is being protected?
   • Assets
2. Who am I protecting it from?  
   • Adversaries
3. How likely is this threat?  
   • Capabilities
4. What are the consequences of failure?
   • Threat
5. How much trouble am I willing to go through to prevent the consequences?
   • Risk

Before a Protest

ssd.eff.org

• Enable full-disk encryption on your device
• Remove fingerprint unlock, pixel imprint, and FaceID
  • biometrics v. passwords - the 5th amendment
• Install Signal
• Back up your data
• Prepaid phone or no phone
• Face protection

At a Protest

ssd.eff.org

• Take photos and videos without unlocking

• Consider biking or walking to the protest

• Enable airplane mode

• IF arrested, remember:

  • request an attorney before/during questioning

  • You can't lie, but officers can (and will)

  • If asked to open your phone say you "do not consent to a search of your device"

  • Remember the 5th amendment!

  • Defending your rights may be penalized

• Not designed for privacy and security
• More locked down with proprietary code, making it harder to control than regular computers.
• Many apps collect and share data
  • Might not need access to your phone to get assets
• Phones and Phone #s attached to our identity, finances, etc

The Problem with Mobile Phones

Code: Instructions for your computer to complete.

"Open Source": A program that lets you read the instructions it contains (and even change them)

Proprietary: A program that keeps their instructions a secret

Phone Prep

"Smart" Components

Your info

• What information are you making available to your phone?
• What info is available to 3rd party programs?
• What info can be picked when your phone communicates with other devices?
• How is location tracked?

• Check your settings!
• Marie Kondo app management
• Use a browser instead of apps!
• Use a computer instead of phone!
• Turn things off! (bluetooth, nfc, etc)

• Check your settings/permissions regularly
• Update update update!
• Avoid new proprietary apps
• Make regular backups of important data!
• Leave your phone at home
• Educate others!
• Advocate for policy changes! (e.g. eff.org)

Let's install Signal

• What does it cost?
  • Nothing! it is a open source non-profit
• Why?
  • Signal offers encrypted texts between users
  • Privacy needs herd immunity
• Is it complicated?
  • It's like any other app, you can also make it your default text app on android
• What are the downsides?
  • It uses mobile data, it is secure but not anonymous-- still uses your phone #

Data in Motion

holistic-security.tacticaltech.org/

How would you make a secret code?

1. iOS/Android groups
2. Go to your app store
3. Search for "Signal"
4. Install the app
5. App setup
6. Safety numbers!
   • What is "verification"?
7. Send a message! (optional)
8. Who will you help install signal?
