Becoming a Human Firewall: Your Idiot's Guide to Spotting and Stopping Social Engineering Attacks

So, we know from our last post about the M&S and Co-op incidents that the bad guys often try to trick people first, this is known as social engineering. But how do you and your team become the digital equivalent of a security guard – a "human firewall"? Well, it's all about knowing what to look out for.

Think of your inbox and your phone as potential minefields. Social engineers are masters of disguise, trying to get you to click, share, or reveal information you shouldn't. Here are some of their favourite sneaky tactics and, more importantly, how to spot them:

Phishing Emails: The Digital Bait

These are the most common. They often look like legitimate emails from banks, online retailers, or even software providers you use.

Red Flags 🚩

Suspicious Sender Address: Does the email address look a bit off? Typos or unusual domains are a giveaway.

Generic Greetings: Instead of "Dear [Your Name]," it might say "Dear Customer" or "Valued User."

Sense of Urgency: They often try to panic you into acting without thinking ("Your account has been locked! Click here now!").

Grammar and Spelling Errors: Professional emails usually don't have obvious mistakes.

Suspicious Links: Top tip: Hover your mouse over the link without clicking to see the actual web address. If it doesn't match what's displayed or looks like a random string of characters, steer clear!

Unexpected Attachments: Be very cautious about opening attachments from unknown senders or unexpected attachments from known ones.

Dodgy Phone Calls (Vishing): The Voice Con

Attackers might call pretending to be from your IT support, a government agency, or even a well-known company.

Red Flags 🚩

Unsolicited Calls: Did you request this call? Legitimate companies usually don't call out of the blue asking for sensitive information.

Demands for Immediate Action or Personal Information: They might pressure you to act quickly or ask for passwords, bank details, or remote access to your computer.

Refusal to Provide Verification: A genuine representative should be able to provide a reference number or allow you to call them back on a known, official number. Remember, legitimate companies will rarely ask for your password over the phone. If in doubt, hang up and call the company back using a number you trust.

Pretexting (Impersonation): Playing a Role

This involves creating a believable scenario to trick you into giving up information. They might pretend to be a colleague, a supplier with an urgent issue, or even a potential customer.

Red Flags 🚩

Unexpected Requests: Be wary of unusual requests for information or actions, even if they seem to come from someone you know.

Lack of Proper Protocol: Does the request bypass normal procedures?

Vague Explanations: If their story doesn't quite add up or they can't provide clear details, be suspicious. Always verify requests through a separate communication channel (e.g., a phone call to a known number or a direct email).

The Role of Training (and How We Can Help!)
