- Tuesday from hell on the security beat. U of Copenhagen’s test env leaked 525k records. We're threadbare when "test" means "live data." Hype doesn't patch holes; OPSEC does. Who gets hurt? Half a million folks with exposed PII. Serious readers: Check the seals on your accounts, enable MFA everywhere, and assume your email is already compromised. Stop kidding yourself that university IT is secure. This isn't crypto, but it's digital infrastructure failure. Relay only on my word before you trust any "secure" portal. Delivery signature applied.
