The Threat of Social Engineering.

You can defend your data with all the latest and best technology. But if just one team member gets tricked into giving away the keys to the castle, it’s game over. Hackers know this. And that’s why so many use social engineering to break in.

And it’s not just the big companies you hear about on the news. On February 3, 2016 a suspect posing as the CEO of Magnolia Health Corp. obtained a spreadsheet with sensitive data about their employees. On February 23, someone posing as an employee of Central Concrete Supply Company obtained confidential W2 records and disappeared with them.

In a 2011 survey, Check Point Software Technologies found that nearly half of the companies surveyed reported one or more social engineering attacks resulting in losses ranging anywhere from $25,000 to $100,000 per occurrence.

Unfortunately, there just aren’t any whiz-bang tricks or tools that will automatically prevent a clever “social engineer” (SE) from breaking in. The keys to protection are awareness and vigilance. To help you know what to watch for, here are five common ploys – and how to deflect them:

Familiarity – In this type of scheme, the hacker becomes familiar to an employee. Social networking sites can reveal an employee’s schedule and favorite hangouts. The hacker might then frequent the same bar or restaurant. After a drink or two, some key fact may slip out… The best way to bust this ploy is to be careful to not get lulled into a false sense of security around people you haven’t thoroughly vetted.

The Consultant – A social engineer poses as a consultant for hire. Once they get the gig they can scoop up all the info they need from you and your team because of their seeming authority. Watch for this especially with IT consultants. Do NOT trust blindly. Vet every consultant, and never give all the keys to the kingdom. Just because someone has the skills to fix your server or network doesn’t mean they won’t steal your data. Vet thoroughly, and, as Ronald Reagan said, ‘trust but verify’.

Piggybacking – The SE waits by a secured door for someone to use their passcode and enters right behind them. Or the SE struggles with a heavy box and asks a legit employee to hold the door open for them. Being kind and helpful, the employee helps the SE right into the building… free to do as they please. To foil this one, never forget the dangers of allowing a stranger in without proper clearance.

The Interview – Key information often escapes during interviews. A smart social engineer will gain an interview and deftly pick up all the information they need to hack into your network. Make sure any data provided during an interview offers nothing in the way of secrets. Keep the conversation light, or even superficial to avoid leaking critical data.

Angry Man – You may have seen this on TV… Somebody has an angry tone on the phone, or is grumbling to themselves as if they’ve just had an argument. We all tend to avoid people like that. Enough people avoid them and the way is cleared into the heart of the company – and your data. Don’t go along with it. When you see this exploit unfolding, call security.

The key to preventing social engineering attacks is a well-trained workforce. You and your people may be your company’s greatest asset. Yet without regular, proper training, human beings can be the weakest link in your company’s data defenses.
