Asher DeMetz of Forbes on the three best hacking techniques to create a security breach:

I find that good, law-abiding citizens are fascinated by what I do. I’m a penetration tester, a.k.a. “white hat” or “ethical” hacker. In other words, companies hire me to break into their systems for a living to demonstrate where there are vulnerabilities. (I can’t believe I get paid for doing this!) If you want to avoid a cyber security breach at your company, I recommend that you understand – and guard against – three hacking techniques that your enemies (the “black hat” hackers) use every day.

First, let’s set the stage. Let’s say that your company is Big Boxes 4U, a major mass-market retailer with more than 1,500 locations in the United States. Your innovative designer partnerships, high-quality product mix, and great customer service have earned you a loyal customer following.

You capture customer information every day at the point of sale, including both in-store and online purchases. The result is a central database that houses a collection of valuable customer information that gives insight into how your customers shop, what they buy, and what products and services they prefer. Just as you value this information, so do hackers. Here’s how they create a cyber security breach.

This is a good, quick read for those who do not really understand hacking techniques and how malicious actors perform some of their cyber operations. It is fairly standard fare if you already are in the industry, but educational if you are unaware of the simple tradecraft.
