Sellers typically use their technical prowess to collect desirable information, or work on behalf of hackers as a front man to offer information. Recently, a hacker claimed to be selling over 32 million Twitter usernames and passwords on an underground marketplace.īut what happens after a breach? What does an attacker do with the information collected? And who wants it, anyway? My research, and various studies from other computer and social scientists, demonstrates that stolen data is usually sold by hackers to others in underground markets online. Though breaches affecting consumer data have become commonplace, there are other resources that, when targeted, lead to major security concerns. Dozens of high-profile breaches over the last few years have targeted national retailers, health care providers and even databases of the federal government, getting Social Security numbers, fingerprints and even background-check results. They generate a great deal of media attention, both because the quantity of information stolen is often large, and because so much of it is data people would prefer remained private.
Data breaches are a regular part of the cyberthreat landscape.
