One of the most visionary information security predictions for 2012, was the one issued by Fortinet which defined the term Crime As A Service: “Crime as a Service (CaaS), [...] is just like Software as a Service (SaaS), but instead of offering legal and helpful services though the Internet, criminal syndicates are offering illegal and detrimental services, such as infecting large quantities of computers, sending spam and even launching direct denial of service (DDoS) attacks“. At first glance I marked this prediction as exaggerated but then I could not imagine that I should have witnessed a huge demonstration only few days after. Of course I am referring to the #OpMegaUpload when, immediately after the FBI takedown, the Anonymous redirected users towards a website when they could DDoS a large group of targets with a simple web click and most of all, without the need to install the Infamous LOIC.
Even if this has been, so far, the most noticeable example, is not the only one of a malicious tool used as a service for criminal (in this case one shot) campaigns. More in general, using very familiar terms (borrowed and adapted from Cloud Terminology) I believe the CaaS is assuming three shapes:
- Software As a (Crime) Service or Saa(C)S, in which the criminals offer malicious software (and the needed support) as a service. An example? The latest Zeus Variant dubbed Citadel, recently spotted by Brian Kerbs, which provides the purchaser with help desk and even a dedicated Social Network;
- Infrastructure As (Crime) Service or Iaa(C)S, in which the criminals offer malicious services (or infrastructures) to attack specified targets, services may include complex “traditional” infrastructures such as botnets, but also “innovative” large scale fashioned services such as DDoS or also sharper services such as password cracking. Try to surf the web and you will discover how easy it is to purchase such a criminal kind of services.
- Platform As a (Crime) Service or Paa(C)S: in which the criminals offer malicious platforms that users may adapt to fit their needs. An example? The brand new HOIC (High Orbit Ion Cannon) the new DDoS tool, evoluti0n of the infamous LOIC, that may be assimilated to a real malicious service platform that users may tailor to fits their needs thanks to the booster scripts. I believe we are not so far from criminal organizations selling customized booster scripts for every kind of need and, why not, offering support services as well.
Last but not least this services are self provisioned, and this is the reason why I used the term “Crime as a Self Service”: in every scenario, be the malicious service a Saa(C)S, Iaa(C)S or Paa(C)S, the user selects directly the target (or the victim), and that’s it!
