A tiny Bluetooth hardware key that unlocks external drives only when my device is nearby. Posted a quick how-to video showing how it works. Simple, secure, elegant.

Yeah I know I said I wouldn’t post for a bit but… hi. I made a thing. It’s called VaultKey. It keeps your encryption key off your computer so remote attackers can’t touch it. Super simple idea, huge impact. 🔐

The Salesforce Gainsight breach shows how attackers don’t need to hack the main system when a smaller app has the keys. Third-party risk is the real threat now.

WhatsApp’s “leak” is just phone numbers and basic account info. It might make phishing more targeted but not more believable. The risks are negligible at best, so I’m not writing an article about something that won’t actually matter. #cybersecurity #infosec #whatsapp #refusetoengage

Gatekeeping is not knowledge management. New staff are not unskilled, they just lack the hidden context others keep in their heads. Instead of “you should know this,” give them tools and clear notes so they can succeed. We rise by sharing knowledge.
