Behavior
When a file infected with Natas is executed, it becomes memory resident, taking up 5,664 bytes in memory and infects the master boot record and COMMAND.COM. The virus infects files when they are executed, opened or copied, appending its 4,746 bytes to .com, .exe and .ovl files.
There is a 1 in 512 possibility Natas will destroy data on a portion of the hard disk every time an infected file is executed, the master boot record is accessed or an infected file is disassembled. It contains the text "Natas" in its encrypted code.
The virus has interesting stealth capabilities. When an archiver is run, it turns its stealth off, so it has more chances to spread. If the user tries to look at the master boot record through a binary editor, SatanBug will show a clean version.
