#OPSEC365 214/365 Granting contact access doesn't expose your data. It exposes everyone else's. Your address book is a social graph belonging to people who never consented. WhatsApp, LinkedIn, and TikTok have all used contact uploads to build graphs of non-users. Cronk's aggregation problem: the app now knows your network position without you ever posting publicly. A photo editor, game, or flashlight has no need for your contacts. Audit and revoke. #OPSEC365

Tor Project "We dislike mullvad donated to someone we dislike." Also Tor: "We accept funding from the feds, and give DC talks about how cool it is that they talk to us."

#OPSEC365 213/365 Your notification center is a summary of your digital life visible on your lock screen. Banking alerts, message previews, calendar reminders, and app notifications all appear where anyone glancing at your phone can see them. The locked screen shows a feed of your recent activity. Review your notification settings and limit what shows when your phone is locked. #OPSEC365

#OPSEC365 212/365 Gait recognition is being marketed as a way to identify you by how you walk. Your stride length, pace, arm swing, and posture create a signature that does not change when you cover your face. Watrix, a Chinese vendor, has publicly claimed 50-meter identification at 94% accuracy with the face fully covered. That figure comes from the company itself and has not been independently validated in peer-reviewed research. #OPSEC365

Regulation was written by the people it's supposed to regulate, and it's been that way since the beginning.

#OPSEC365 211/365 Shared computers retain browsing history across users. Family computers, library terminals, and shared workstations keep history unless actively cleared. Private browsing helps during the session but doesn't erase what you did before remembering to use it. The next person at that computer can see what you browsed. Always use private browsing on shared computers and clear history if you forget. #OPSEC365

#OPSEC365 210/365 Bitcoin transactions are traceable despite claims of privacy. The blockchain is a public ledger. Every transaction is recorded permanently. Chain analysis companies like Chainalysis correlate wallet addresses with identities. Law enforcement routinely traces Bitcoin transactions to identify users. If you need financial privacy, understand that Bitcoin provides pseudonymity at best, not anonymity. #OPSEC365

Things happen, we learn and adapt. The most important lesson in life is to not make the same mistake twice. Hope all the best for Dread, and Paris. If the site ever shuts down, I will publish my archived backup.

#OPSEC365 209/365 Location stickers on social media stories reveal where you are in real time. Instagram and Snapchat location tags show your current location to everyone viewing your story. Unlike posts, stories broadcast where you are right now, not where you were last week. Check-ins announce your presence to anyone following you. Anyone watching can screenshot the tag before the story expires. #OPSEC365
