Using the same password twice means a breach at some site you forgot about can get someone into your business email. Attackers take leaked passwords and try them everywhere automatically. A strong password doesn't help if you reused it. Use a password manager and turn on MFA.

If a website tells you to press Windows+R and paste in a command to 'verify you're human,' close the tab. That's a scam called ClickFix, and it installs malware the second you hit Enter. No real website ever asks you to run a command. CAPTCHAs just make you click pictures.

ClickFix attacks are delivering BabaDeda, Lorem Ipsum, and Potemkin loaders to deploy stealers, RATs, and ransomware-linked tooling.

Your cyber insurance might not pay out. Insurers now require MFA, real endpoint protection, tested backups, and security training, and if you claimed to have them but didn't, they can deny the claim. Read your policy's conditions now, not after an attack.

Anyone can send an email that looks like it's from your company. Three DNS records stop it: SPF, DKIM, and DMARC. The catch is DMARC is often set to 'monitor only,' which watches spoofing happen without blocking it. Ask your IT provider: is ours set to reject, or just none?

Many ransomware groups delete your backups before they lock your files, so paying becomes the only way out. Keep one backup copy offline with its own login, separate from your admin password, and test a restore this month. If you've never tried it, you don't know it works.

We use QR codes for almost everything now, from restaurant menus to paying for parking.

The problem is that we've started to trust them, and scammers are using that trust against us.

A common scam is to put a sticker with a fake QR code on top of a legitimate one.

When you scan the fake code, it takes you to a website that might look real but is designed to steal your password or credit card info.

Since you can't see the website address hidden inside the code, it's hard to spot the fake. This is sometimes called "Quishing."

It's a good idea to get into the habit of checking a few things first:

▶️ Check the code itself. Does it look like a sticker that's been placed over the original one? If anything seems off, don't scan it.
▶️ Preview the website address. After scanning, your phone shows you the link before it opens. Read it. If the address doesn't look right, don't open the site.
▶️ Don't enter passwords. If a QR code takes you straight to a login page, it's almost always a scam. Just close the window.

It all comes down to taking an extra second to look before you open the link. Too many people fall for this scam, so stay vigilant and stay safe!

Your team is using AI right now, whether you have a policy on it or not.

ChatGPT, Gemini, Copilot, Claude, and a dozen niche business tools are in the workflow of someone in your business this week. These tools learn from what you type, sometimes retain it for training, and live outside whatever data security setup you've built for the rest of the business.

Without a written policy, you have no way to know what client data is being pasted into prompts, which business decisions are being made with AI assistance, or how your insurance views any of it if something goes wrong.

An AI Acceptable Use Policy doesn't have to be 30 pages. A one-page version covers the essentials: which tools are approved, what data is forbidden as input, what disclosure rules apply to AI-generated work, and who reviews AI output before it goes to a client.

If you want a full AI Acceptable Use Policy template to implement in your business, comment below with "AI Policy" and we'll send it to you.
