F-Secure Virus Descriptions : EkoTerror
This virus contains a lot of bugs but also some quite sophisticated
routines like stealth capabilities and debug tricks. The virus may be
have escaped from its developer when still in beta.
EkoTerror set a lot of conditions and therefore spreads slowly. It
infects COM files and hard disk master boot sectors (MBR). It may
infect a file more than once.
The virus moves the original MBR and partition table to sector 5 of
the hard disk, overwriting the original ones with its own code.
Due to a bug in the virus, most computers do not boot after the MBR
has been infected.
The virus contains the following text:
Copyright (C) 1984 BORLAND Inc
This probably means that the virus was compiled with a Borland
compiler.
EkoTerror activates on random dates when the computer is booted. It
displays the following message at system startup:
EkoTerror (C) 1991 ATK-toimisto P.Linkola Oy
Kovalevysi on poistettu k„yt”st„ luonnonsuojelun nimess„.
Vihre„ss„ yhteiskunnassa ei saa olla ydins„hk”ll„ toimivia kovalevyj„.
The message is in Finnish and reads:
EkoTerror (C) 1991 ATK-toimisto P.Linkola Oy
Your hard disk has been disabled for protecting the environment.
There must not be any nuclear powered hard disks in a green society.
While displaying the message, the virus overwrites the first sectors
of the hard disk. After overwriting them, it hangs the computer by
entering an infinite loop.
EkoTerror was reported to be in the wild in Finland in June 1992.
