Jackal
Jackal is a dangerous memory resident multipartite virus. On execution of infected file it traces INT 13h, 15h, 21h, 40h and then hooks them. Then this virus hits MBR of hard drive, it changes the address of active boot sector and writes itself at this address. On system booting the virus body will be executed instead of original boot sector. Then this virus writes itself at the end of COM- and EXE-files that are accessed.
Sometimes it calls trigger routine, this routine formats the hard drive sectors. The virus hooks INT 9 (keyboard) also and on Alt-Ctrl-Del pressing it tries to stay memory resident after rebooting: it restores the interrupt table, clears the screen e.t.c.
This virus contains the internal string "JaŠckŠal". |
