About Constructors

A Constructor is a virus creation toolkit used by malware authors to assemble malware from prepared 'building blocks' of code. Such programs allow users with little technical knowledge to easily create a complex polymorphic malware. The most famous Constructors are VCL, SennaSpy, BWG, PS-MPC, TPPE and IVP .

Constructor kits come with a variety of options, ranging from very simple to very sophisticated. A typical kit is very easy to use, as it eliminates the need for programming knowledge and skills. A user can create malware simply by selecting the features desired.

A Constructor kit's ease of use is demonstrated by an incident in which an unknown person created more than 15,000 viruses using a constructor and sent them to antivirus companies. Fortunately, because the malware produced from these programs uses a finite set of code blocks and known polymorphic engines, they can be detected using Generic Detections.
