It takes a lot for me to write a cybersecurity blog post these days. I spend most of my writing time working on my PhD. Articles like Nothing Brings Banks Together Like A Good Hack drive me up the wall, however, and a Tweet rant is insufficient. What fired me up, you might ask? Please read the following excerpt:
[Troels] Oerting, with no small dose of grudging admiration, says his adversaries excel at something that can’t be addressed with deep pockets or killer software: They’re superb networkers. “The organized crime groups in cyber are sharing much better than we are at the moment,” says Oerting, a Dane with a square jaw and the watchful eyes of a cop who’s investigated the underworld for 35 years. “They are sharing methodologies, knowledge, tools, practices—what works and what doesn’t.”
Statements like these are regularly submitted without evidence. In response, I provide five sources of evidence why organized crime groups do not share more than defenders.
1. Solution providers share. Both commercial and not-for-profit solution providers share enormous amounts of information on the security landscape. Some of it is free, and some of it is sold as products or consulting. Thousands of security companies and not-for-profit providers compete for your attention, producing white papers, Webinars, and other resources. You might argue that all of them claim to be the answer to your problem. However, this situation is infinitely better than the 1980s and early 1990s. Back then, hardly any solutions, or even security companies and organizations, existed at all.
Criminal solution providers share, but they do so by selling their wares. This is true for the open world as well, but the volume of the open world is orders of magnitude greater.
2. Government agencies share. My fellow Americans, has your organization you been visited by the FBI? Federal agents notified more than 3,000 U.S. companies [in 2013] that their computer systems had been hacked. The agents didn't just walk in, drop a letter, and leave. If a relationship did not exist previously, it will now be developed.
Beyond third party breach notifications, agencies such as NIST, DHS, and others regularly share information with organizations. They may not share as much as we would like, but again, historical perspective reveals great progress.
3. Books, articles, and social media share. The amount of readable material on security is astounding. Again, in the late 1980s and early 1990s hardly any books or articles were available. Now, thousands of resources exist, with new material from publishers like No Starch arriving monthly. Where are the books written by the underground?
4. Security conferences share. You could spend every week of the year at a security conference. If you happen to miss a talk, it's likely the incomparable Iron Geek recorded it. Does the underground offer similar opportunities?
5. Private groups and limited information exchange groups share. A final category of defender sharing takes place in more controlled settings. These involve well-established Information Sharing and Analysis Centers (ISACs), developing Information Sharing and Analysis Organizations (ISAOs), and private mailing lists and forums with limited membership. These could possibly be the closest analogue to the much-esteemed underground. Even if you disregard points 1-4 above, the quality of information shared in this final category absolutely equals, if not exceeds, anything you would find in the criminal world.
If you disagree with this analysis, and continue to lament that bad guys share more than the good guys, what evidence can you provide?
