CIH, also known as Chernobyl or Spacefiller, is a
Microsoft Windows 9x computer virus
which first emerged in 1998. Its payload is highly destructive to vulnerable systems, overwriting critical information on infected system drives, and in some cases destroying the system BIOS.
What does Chernobyl virus do?
The Chernobyl virus is a
computer virus with a potentially devastating payload that destroys all computer data when an infected file is executed
. Since many files are executed during computer use, the virus is able to spread quickly and infect those files.
What is a cavity virus?
Some viruses can infect files without increasing their sizes or damaging the files. They accomplish this by
overwriting unused areas of executable files
. These are called cavity viruses. For example, the CIH virus, or Chernobyl Virus, infects Portable Executable files.
How does a multipartite virus work?
A multipartite virus is defined as a virus
that infects your boot sector as well as files
. The area of the hard drive that is accessed when the computer is first turned on. Can infect floppy disks.
What is polymorphic virus?
Polymorphic viruses are
complex file infectors that can create modified versions of itself
to avoid detection yet retain the same basic routines after every infection. To vary their physical file makeup during each infection, polymorphic viruses encrypt their codes and use different encryption keys every time.
Is Stone a virus?
Virus:Boot/Stoned is a
simple virus
that seems to have been designed to be harmless. Due to a mistake however, it did not quite work out that way. Stone is able to infect the boot sectors of floppy disks. The virus has spawned a large number of variants.
What is the mother of all viruses?
Security professionals say it is “the mother of all computer viruses.” The alert is out for what’s being called
the Remote Explorer virus
: the first virus in history that infects entire computer networks instead of individual computers.
What is a tunneling virus?
A tunelling virus is a virus that
attempts to intercept anti-virus software
before it can detect malicious code. A tunneling virus launches itself under anti-virus programs and then works by going to the operating system’s interruption handlers and intercepting them, thus avoiding detection.
What is rootkit virus?
The whole purpose of a rootkit is
to protect malware
. Think of it like an invisibility cloak for a malicious program. This malware is then used by cybercriminals to launch an attack. The malware protected by rootkit can even survive multiple reboots and just blends in with regular computer processes.
What is non resident virus?
Viruses propagate themselves by infecting applications on a host computer. A resident virus achieves this by infecting applications as they are opened by a user. A non-resident virus
is capable of infecting executable files when programs are not running.
Is Trojan a virus?
A Trojan horse, or Trojan, is a
type of malicious code or software
that looks legitimate but can take control of your computer. … A Trojan is sometimes called a Trojan virus or a Trojan horse virus, but that’s a misnomer. Viruses can execute and replicate themselves.
What is multipartite virus example?
Alternatively, enveloped animal viruses, with genomes wrapped in nucleocapsids, could be another source for filamentous multipartite viruses. An example might be
Rhabdoviridae
, a family of enveloped viruses infecting invertebrates including bipartite genera infecting plants.
Who invented multipartite virus?
| Original author(s) Unknown | Initial release October 1989 | Operating system DOS |
|---|
Can antivirus detect polymorphic virus?
Many malware strains now have polymorphic capabilities, rendering traditional antivirus solutions ineffective at detecting and stopping the malware prior to compromise.
Why Dyre is a polymorphic virus?
Dyre is what is known as a polymorphic virus.
Once it infects a host machine, it replicates and sends itself out to everyone in your contact list
. Anyone that gets infected in turn sends out an entirely new variant. Antivirus is useless against it.
Who invented polymorphic virus?
The first known polymorphic virus was written by
Mark Washburn
. The virus, called 1260, was written in 1990. A better-known polymorphic virus was created in 1992 by the hacker Dark Avenger as a means of avoiding pattern recognition from antivirus software.
