Security Awareness
The habits that stop almost everything.

Your info is probably already out there
Assume your email and some old passwords have turned up in a breach. That is true for almost everyone, and it isn't on you. Companies you trusted got hit. What counts now is making that old data useless.
Check your exposure haveibeenpwned.comSpotting a phish
A phishing message wants you to act before you think. It shows up by email, by text (smishing), by phone call (vishing), even as a QR code. AI writes them cleanly now, so good spelling isn't proof it's real. The tells still hold:
- 1Urgency"Act now or else."
- 2Odd senderFamiliar name, address slightly off.
- 3Strange askA password, a payment, gift cards.
- 4Out of nowhereYou didn't ask for this.
- 5"Dear Customer"Generic greeting, not your name.
Check where a code takes you
QR codes carry scams too, and it's climbing fast. A sticker placed over the real code on a parking meter or a flyer, or a code dropped into an email, can open a fake login or payment page that looks right.
- After it opens, read the address before you type anything. Does the domain actually match the company?
- Be suspicious if a scan jumps straight to a login or a payment.
- On a printed code, check it isn't a sticker placed over the original.
The one that matters most
Get these right and you've closed most of the door. Honestly this counts for more than the rest put together.
Do
- Use a password manager. One master password, a strong unique one everywhere else.
- Turn on MFA, and switch to passkeys wherever they're offered.
- Give fake answers to security questions, kept in the manager.
Don't
- Reuse one password across sites.
- Approve a login prompt you didn't start.
- Log in from a link in a message. Open the site yourself.
When the voice or face is faked
Cloning a voice or a face is cheap now, and a few seconds of audio is enough. A call or even a video can sound and look like your boss or a family member, pushing you to move money or hand over access fast.
Treat personal data like it's borrowed
Names, emails, phone numbers, addresses, payment details. Yours and other people's. When you hold data on customers and contacts, you're responsible for it, and that's where a small slip becomes a real problem.
- Keep only what you need, and give access on a need to know basis.
- Keep customer and contact PII out of AI tools and random websites. Once it's in, you can't get it back.
- Send sensitive files with expiring, named, view-only links, not "anyone with the link."
- If PII might be exposed, report it fast. Speed limits the damage.
It's about your account and your data now
If your files live in the cloud, version history usually handles the old "everything got encrypted" attack. The risk moved to attackers signing in as you and stealing data to leak it, which version history does nothing about.
- The protection that matters most is your login. Use passkeys and keep MFA on.
- Keep less customer data in your files than you think you need. Less to steal.
- If files look renamed or encrypted, or a ransom note appears, disconnect and report right away. Don't pay, and don't try to fix it yourself.
Say something, fast
Most of the damage happens in the gap between "that was weird" and someone doing something about it. Reporting early is the single most useful habit on this list.
- If you clicked, entered a password, or sent something you shouldn't have, report it right away.
- Speed beats embarrassment. The sooner it's flagged, the less it costs.
- You won't be in trouble for reporting, even if it turns out to be nothing.
