Rivpas is a proof-of-concept script written in SAP's application development language, Advanced Business Application Programming (ABAP) language. This script is supposed to show that a virus can be written for this platform, however, the sample is intentionally made not to replicate.
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
First the script attempts to find the SAP's report directory and tries to find functions and reports to infect.
If an suitable object is found, the virus will try to inject its code in there.
The virus sets the username of an infected object to "Virii" and uses this as a infection marker.
