- Adware
Programs that facilitate delivery of advertising
content to the user through their own window, or by utilizing another
program's interface. In some cases, these programs may gather
information from the user's computer, including information related to
Internet browser usage or other computing habits, and relay this
information back to a remote computer or other location in
cyber-space.
- Adware can be downloaded from Web sites
(typically in shareware or freeware), email messages, and instant
messengers. Additionally, a user may unknowingly receive and/or trigger
adware by accepting an End User License Agreement from a software
program linked to the adware or from visiting a website that downloads
the adware with or without an End User License Agreement.
- Dialers
Programs that use a computer or modem to dial out to a
toll number or internet site, typically to accrue charges. Dialers can
be installed with or without a users explicit knowledge, and may perform
their dialing activity without a users specific consent prior to
dialing.
- Hack Tools
Tools that can be used by a hacker or unauthorized user
to attack, gain unwelcome access to or perform identification or
fingerprinting of your computer. While some hack tools may also be valid
for legitimate purposes, their ability to facilitate unwanted access
makes them a risk. Hack tools also generally:
- Attempt to gain information on or access hosts
surreptitiously, utilizing methods that circumvent or bypass obvious
security mechanisms inherent to the system it is installed on,
and/or
- Facilitate an attempt at disabling a target
computer, preventing its normal use
- One example of a hack tool is a keystroke
logger -- a program that tracks and records individual keystrokes and
can send this information back to the hacker. Also applies to programs
that facilitate attacks on third-party computers as part of a direct or
distributed denial-of-service attempt.
- Joke Programs
Programs that alter or interrupt the normal behavior of your
computer, creating a general distraction or nuisance. Joke programs
generally do not themselves engage in the practice of gathering or
distributing information from the user's computer.
- Remote Access
Programs that allow one computer to access another
computer (or facilitate such access) without explicit authorization when
an access attempt is made. Once access is gained, usually over the
Internet or by direct dial access, the remote access program can attack
or alter the other computer. It may also have the ability to gather
personal information, or infect or delete files. They may also create
the risk that third party programs can exploit its presence to obtain
access. Such remote access programs generally:
- Attempt to remain unnoticed, either by
actively hiding or simply not making their presence on a system known to
the user, and/or
- Attempt to hide any evidence of their
being accessed remotely over a network or Internet
- Means by which these programs provide
access may include notifying a remote host of the machine by sending its
address or location, or employing functionality that wholly or partially
automates access to the computer on which the program is installed.

- Spyware
Programs that have the ability to scan systems or
monitor activity and relay information to other computers or locations
in cyber-space. Among the information that may be actively or passively
gathered and disseminated by Spyware: passwords, log-in details, account
numbers, personal information, individual files or other personal
documents. Spyware may also gather and distribute information related to
the user's computer, applications running on the computer, Internet
browser usage or other computing habits.
- Spyware frequently attempts to remain
unnoticed, either by actively hiding or by simply not making its
presence on a system known to the user. Spyware can be downloaded from
Web sites (typically in shareware or freeware), email messages, and
instant messengers. Additionally, a user may unknowingly receive and/or
trigger spyware by accepting an End User License Agreement from a
software program linked to the spyware or from visiting a website that
downloads the spyware with or without an End User License Agreement.
- Trackware
Programs that track system activity, gather system
information, or track user habits and relay this information to
third-party organizations. The information gathered by such programs is
neither personally identifiable nor confidential.
- Trackware programs are installed with the user's
consent and may also be packaged as part of other software installed by
the user.
- Viruses, Worms and Trojan
Horses
A virus is a program or code
that replicates itself onto other files with which it comes in contact;
that is, a virus can infect another program, boot sector, partition
sector, or a document that supports macros, by inserting itself or
attaching itself to that medium. Most viruses only replicate, though
many can do damage to a computer system or a user's data as well.
- A worm is a program that makes and facilitates
the distribution of copies of itself; for example, from one disk drive
to another, or by copying itself using email or another transport
mechanism. The worm may do damage and compromise the security of the
computer. It may arrive via exploitation of a system vulnerability or by
clicking on an infected e-mail.
- A Trojan Horse portrays itself as something
other than what it is at the point of execution. While it may advertise
its activity after launching, this information is not apparent to the
user beforehand. A Trojan Horse neither replicates nor copies itself,
but causes damage or compromises the security of the computer. A Trojan
Horse must be sent by someone or carried by another program and may
arrive in the form of a joke program or software of some sort. The
malicious functionality of a Trojan Horse may be anything undesirable
for a computer user, including data destruction or compromising a system
by providing a means for another computer to gain access, thus bypassing
normal access controls.
- Other
Risks that do not meet the definitions of Viruses,
Trojan horses, Worms, or other security risk categories, but which may
present a risk to a computer and its data, an unwanted nuisance to the
user, or exhibit other unexpected or unwanted results when the risk is
present and functioning. This category includes programs that encrypt or
otherwise attempt to obfuscate some of their functionality, making it
difficult to determine whether they fall into one of the other
categories. |
