Picture this: You’re going about your day, checking your emails, when suddenly you see a message from a company you trust, like your managed IT service provider.   You think, “Great! That’s safe to read”. But hold on just one minute… this email is not what it seems.  It’s part of yet another scam created by cyber criminals to trick you into clicking malicious links or giving up sensitive info. It’s called “SubdoMailing,” and it’s as dangerous as it sounds. What’s the deal?  

Just like regular phishing attacks, cyber criminals pretend to be trusted brands.   

But here’s how it works: These cyber criminals scour the internet for subdomains of reputable companies. You know those extra bits in a web address that come before the main domain? Such as experience.trustedbrand.com. That ‘experience’ bit is the subdomain. They find a subdomain that the brand is no longer using and is still pointing to an external domain that’s no longer registered. Then they buy the domain and set up the scam website. So, you believe you’re clicking on experience.trustedbrand.com… but you have no idea it automatically redirects to scamwebsite.com. The criminals are sending out five million emails a day targeting people in businesses just like yours. And because these emails are coming from what seems like a legit source, they often sail right past usual security checks and land in your inbox.  

Here’s our advice to keep you and your data safe and sound: 

  • Be wary of any emails that seem even remotely suspicious. If something looks fishy, it probably is. 
  • Before clicking on any links or downloading any attachments, take a moment to verify the sender. Look for red flags like spelling mistakes or unusual email addresses. 
  • Make sure your employees understand the latest phishing tactics and know how to spot a scam. A little knowledge goes a long way in keeping your company safe. 
  • Consider investing in top-notch security software to keep the cyber criminals at bay. It might seem like an extra expense, but trust us, it’s worth it.
