This is a harmless non-memory resident parasitic Linux virus. The virus is a Linux executable module (.ELF file). It searches for other .ELF files in the system, and then infects them. The virus infects files in the following directories:
- current directory
- parent directory
- ~/ (user root directory)
- ~/bin (user /bin directory)
- ~/sbin (user /sbin directory)
While infecting, the virus moves a victim's file contents down, and writes itself to the file header. To release control to the host file, the virus "disinfects" it to a temporary file and executes it.
The virus does not manifest itself in any way. Its body contains the "copyright" text string:
