Emerging threat: Social Botnets

We think of botnets as networks of computing devices slaved to some command & control system. But what about human-in-the-loop botnets, where humans are either participants or prime actors? I’m coining this label: “social botnets”. Recent example: “Health Insurers Caught Paying Facebook Gamers To Oppose Reform Bill”.

NEW: Verizon 2009 DBIR Supplement

The supplement provides case studies, involving anonymous Verizon clients, that detail some of the tools and methods hackers used to compromise the more than 285 million sensitive records that were breached in 90 forensic cases Verizon handled last year.

Manditory web client scripts analogous to CDOs

The widespread and often mandatory use of client scripts in websites (e.g., JavaScript) are like CDOs [Collateralized Debt Obligations}. They both are designed by others with little interest in your security, they leverage your resources for their benefit, they are opaque, complex, nearly impossible to audit, and therefore untrustworthy.

Time to update your threat model to include “friendly fire”

If you work in InfoSec outside of the military, you may be thinking that “offensive cyber capability” don’t doesn’t apply to you. Don’t be so sure. I think it’s worth adding to the threat model for every organization. New “hacking gadgets” could be put in the hands of ordinary soldiers, turning them into the equivalent of “script kiddies”. But what if the potential target knows that such attacks may be coming. They could sets up a deceptive defense and redirect the attack to another network

Can quantitative risk estimation serve as a guide for every-day policy decisions?

A methodology is presented for guiding individual policy decisions from a risk management perspective, using a form of “abduction validation”. An example is presented using the case of password change policy, drawing from recent blog discussions.

Miscommunicating risks to teenagers

A lesson in miscommunication of risk from “abstinence only” sex education aimed at teenagers. The educators emphasize the failure rate of condoms, but never mention the failure rate of abstinence-only policies when implemented by teenagers.

Information Security as an Evolutionary Arms Race – Research Collaborators Wanted

I’m starting on an academic-oriented research project on the arms race between attackers and defenders from the perspective innovation rates and “evolutionary success” – The Red Queen problem. I’m looking for collaborators, contributors, reviewers, etc.

Hackers treated as credible sources of information (D’oh!)

Contrary to popular belief, hackers are not credible sources of information that they themselves have stolen and leaked. Maybe they weren’t “hackers” at all. News organizations and bloggers should think more critically and do more investigation before they add to the “echo chamber effect” for such reports.

The cost of false positives in detection (lessons from public health)

Lessons for information security from recent public health pronouncements on mammographs and Pap tests.

Can’t tell the players without a program

You can’t tell the good guys from the bad guys without knowing the color of their hat. I wish there were some sort of map of the Black Hat ecosystem because it’s hard for non-specialists to tell. Case in point: Virscan.org. Looks like a nice, simple service that scan uploaded files using multiple AV software with latest signatures. But it seems *much* more useful to bad guys (malware writers and distributors) than for good guys. Who does it serve?
