Brief Description 

    

Hisob.A is a worm that has no destructive effects. It passes itself off as a virus detection tool provided by the Spanish computer security company Hispasec.

Hisob.A spreads via email in a message written in Spanish and through peer-to-peer file sharing programs (P2P).

Visible Symptoms 

    

Hisob.A is difficult to recognize, as it does not display any messages or warnings that indicate it has reached the computer.

However, when it spreads via email, it reaches the computer in a message written in Spanish with instructions about how to obtain a free virus detection tool. The message has the following characteristics:

  • Subject:
    HispaSeG Iberica le recomienda que lea este mensaje
  • Attached file:
    TEST DE SEGURIDAD.ZIP
    This file consists of an executable file protected with password and an image called PASSWORD.BMP, which contains the password necessary to extract the worm.
