🔐 STOP OVERCOMPLICATING YOUR SECURITY. THESE 17 STEPS ARE FREE. Good news: no new device, no subscription. Bad news: nobody is going to do it for you. Start with this test. Your laptop and phone get stolen tonight. Locked: do you still have access to everything? Unlocked: could someone empty your wallets in two clicks? Malware on your computer is the unlocked scenario. Habits • Auto-updates on everything, and don't postpone the Chrome update. • Urgent message? Do nothing. Open the official app or call back yourself. Urgency is the scammer's main tool. • Never enter your seed after an email, call or letter. After every big hack, fake "your seed is compromised" letters show up, sometimes by post. • Never paste a command someone sends you into your terminal. Classic one on video calls: "I can't hear you, run this to fix Zoom." Computer • Full-disk encryption: FileVault (Mac), BitLocker (Windows), LUKS (Linux). • Firewall on. On Mac, I use LuLu and BlockBlock, free and open source. • Turn on Lockdown Mode on your iPhone and Mac. • No hot wallet on your computer. It's a matter of time. • Passwords only in a password manager (KeePassXC is free), never in the browser or in cleartext. Browser passwords are the first thing malware grabs. Accounts • Bookmark the login pages you use and only log in from there. The top Google result is often a sponsored ad, and fake ads are a favorite phishing trick. • 2FA everywhere, starting with your password manager. • Remove your phone number from 2FA and recovery. SIM swaps still drain people. Seed • Never digital: no notes, photos, cloud or password manager. I still find seeds in password managers way too often. • Split it across 3 papers: words 1-16, 9-24, and 1-8 + 17-24. Any 2 rebuild it, one alone is useless. Keep them in 3 different places. Real life • Google yourself down to page 5 and request removal of your address. • Don't talk about your holdings. Some attackers assume "in crypto" means millionaire. • Keep a small decoy wallet. If someone threatens you, give it. Your life comes first. Anyone who contacts you first offering to recover your funds is the second scam.

Everybody rushes to buy YubiKeys after the last attacks. Good, but not enough. A YubiKey protects the login, not what happens after. Infected laptop? Malware steals your session and the attacker gets in, no key needed. YubiKey + EDR. Do not be the easy target.
