Brief Description 


Disemboweler is a worm that spreads very quickly via:

  • E-mail messages that can be identified by their subject, which contains a legal term. These messages are automatically sent to all the e-mail addresses in the affected computer.
  • Computer networks, whose workstations share files with an EXE or SCR extension.

The effects of Disemboweler are particularly damaging, as it deletes all the contents of the hard drives, a month after it has carried out its infection.

Visible Symptoms 


A clear indication that you have received Disemboweler is a suspicious e-mail message with a legal term in its subject, such as: sentences you, sufficiency of proof, trial court, against the accused...

Another symptom that indicates that infection has been carried out is the disappearance of the content of the disk drives.
