This loose category includes a variety of Trojans that damage victim machines or
threaten data integrity, or impair the functioning of the victim machine.
Multi-purpose Trojans are also included in this group, as some virus writers
create multi-functional Trojans rather than Trojan packs.
Spyware is computer software that is installed surreptitiously on a personal computer
to intercept or take partial control over the user's interaction
with the computer, without the user's informed consent.
While the term spyware suggests software that secretly monitors the user's behavior,
the functions of spyware extend well beyond simple monitoring.
Spyware programs can collect various types of personal information,
such as Internet surfing habit, sites that have been visited,
but can also interfere with user control of the computer in other ways,
such as installing additional software, redirecting Web browser activity,
accessing websites blindly that will cause more harmful viruses,
or diverting advertising revenue to a third party.
Spyware can even change computer settings, resulting in slow connection speeds,
different home pages, and loss of Internet or other programs.
In an attempt to increase the understanding of spyware, a more formal classification
of its included software types is captured under the term privacy-invasive software.
Backdoors are the most dangerous type of Trojans and the most popular.
Backdoors open infected machines to external control via Internet.
They function in the same way as legal remote administration programs used by system administrators.
This makes them difficult to detect.
Backdoors are installed and launched without the consent of the user of computer.
Often the backdoor will not be visible in the log of active programs.
Once a backdoor has been successfully launched, the computer is wide open.
Backdoor functions can include:
- Launching/ deleting files
- Sending/ receiving files
- Deleting data
- Displaying notification
- Rebooting the machine
- Executing files
Backdoors are used by virus writers to detect and download confidential information,
execute malicious code, destroy data, include the machine in bot networks and so forth.
Backdoors combine the functionality of most other types of in one package.
Backdoors have one especially dangerous sub-class: variants that can propagate like worms.
Many trojans and backdoors now have remote administration capabilities
allowing an individual to control the victim's computer.
Many times a file called the server must be opened on the victim's computer before
the trojan can have access to it.
These are generally sent through email, P2P file sharing software,
and in internet downloads. They are usually disguised as a legitimate program or file.
Many server files will display a fake error message when opened, to make it seem like it didn't open.
Some will also kill antivirus and firewall software.
Some RAT trojans are pranks that are most likely being controlled by a friend or enemy on
April Fool's day or a holiday. Prank RATS are generally not harmful, and won't log keystrokes or hack.
They usually do whimsical things like flip the screen upside-down, open the CD-ROM tray,
and swap mouse buttons. However, they can be quite hard to remove.
Exploits use vulnerabilities in operating systems and applications to achieve the same result.
