Linux/Staog: "This virus spreads only under Linux operating system, infecting Elf-style executables. Found in the fall of 1996, Staog is the first known Linux virus.
Staog is written in assembler. It attempts to stay resident and infect binaries as they are executed by any user. Stoag tries to subvert root access via three known vulnerabilities (mount buffer overflow, tip buffer overflow and one suidperl bug)."
Linux/Bliss: "This virus spreads only under Linux operating system, infecting Elf-style executables. Found in the wild in February 1997, Bliss is the second known Linux virus (first being Staog).
Bliss locates binaries with write access and overwrites them with it's own code. When an infected file is executed, the original program does not gain control at all. However, it is still possible to clean infected files"
Linux.RST.B: "Linux.RST.B is a linux-based virus that infects ELF files and has backdoor capabilities."
MacOS.Sevendust: "There are 6 variants of this virus, including 4 polymorphic, encrypted ones. The differences are described below. What they have in common is that they all infect applications by modifying MDEF and MENU resources, and they can create a System Extension (with an invisible character at the beginning of the name so it loads early) or add an INIT resource to the System file. The existence of the extension is the easiest way of identifying its presence without using NAV.
Also Known As: MDEF 9806, MDEF 666, Graphics Accelerator, SevenDust
Type: Virus
Infection Length: Depends upon variant. See Short Description.
Systems Affected: Macintosh"
Bocs, de ezek nem vírusok? Akkor mik?
"van 1-2 worm"
...ami igen hasonlít a vírusra, csak annyi a különbség, hogy nincs szükségük gazdaprogramra.
