  <meta name="Description" content="Features: Late in summer 1992 the next virus toolkit software was published: the Virus Creation Laboratory or VCL. Behind VCL stands the Nowhere Man, a member of the American group of virus writers, NuKE. VCL is quite a remarkable product: it features a colorful graphical interface of nearly commercial quality with mouse control and drop-down menus, it is installed with a separate installation program and it is supplied with quite accurate and well-written documentation. VCL also contains the ICO and PIF files, with which it can be handily installed in the Windows Program Manager. It is possible to easily create several different kinds of viruses with VCL. From the menus one can choose between a COM file -infecting, a companion virus or an overwriting one. In addition to those, Trojan Horses and Logical Bombs can also be made with VCL. The Virus Creation Laboratory is an application of considerable versatility. By using it, it is possible to define exact activation conditions for a virus made with it, those being, for example, the date, time of the day, the number of infected files, a computer's country code, the version of DOS or the amount of available RAM. VCL presents many alternatives for the activation routine of a virus or a Trojan Horse. Selections mentioned on the menu are crashing the computer, a corruption of files, the printing of a freely chosen text on the screen or printer, the overwriting of whole disks and the playing of a music sample that can be freely composed. In addition to this, the user can add routines to the program's menu. When a user has chosen the desired options, VCL creates the assembler-language source code of a virus or a Trojan Horse on the disk. The user can, if he so wishes, edit it still further before compiling it into an executable form. Despite its great versatility, VCL has not become very popular among virus hobbyists. There are many reasons for this, but the most important probably is that the majority of anti-virus programs were able to find almost all the viruses made by VCL soon after it had been published. In fact, F-PROT recognized most of them even before VCL had been analyzed at all. The functionality of VCL at the hands of virus tinkers is further reduced by the fact that it occasionally makes viruses that do not work at all - most of the source codes it creates cannot even be compiled with an assembler compiler.

There are many interesting details to be found in the extensive documentation of VCL. Among other things, the Nowhere Man forbids the makers of anti-virus software from extracting search character strings from VCL or the viruses made by it. The initial package came with 8 viruses made with VCL and by now numerous viruses made with VCL are roaming the VX-boards. In April 1994 Firecracker (then NuKE) released his VCL Mutator intended to make VCL viruses unscannable again."/>
