In the waning days of that year they hit the mother lode, thanks to Russian hackers identified by federal investigators as Hacker 1 and Hacker 2. Located in the Netherlands and California, the hackers identified a garden-variety flaw on the website of Heartland Payment Systems, a payment card processor that handled some 100 million transactions per month for about 250,000 merchants.

A to Z : What is Security Culture. A security culture is a set of customs shared by a community whose members may be targeted by the government, designed to minimize risk.
Having a security culture in place saves everyone the trouble of having to work out safety measures over and over from scratch, and can help offset paranoia and panic in stressful situations—hell, it might keep you out of prison, too. The difference between protocol and culture is that culture becomes unconscious, instinctive, and thus effortless; once the safest possible behavior has become habitual for everyone in the circles in which you travel, you can spend less time and energy emphasizing the need for it, or suffering the consequences of not having it, or worrying about how much danger you’re in, as you’ll know you’re already doing everything you can to be careful.
