A

 

Adware

Adware is software that displays advertisements on a device, redirects the user’s search requests and collects marketing data about the user. Adware may collect data with or without the user’s consent. If the adware does not notify the user that it is gathering data and obtain permission, it is considered malicious.

Affinity Fraud

Affinity Fraud refers to investment scams that prey upon members of groups and organizations, such as religious or ethnic communities, the elderly or professional groups. The fraudsters who promote affinity scams frequently are – or pretend to be – members of the group. These scams exploit the trust and friendship that exist in groups of people who have something in common. 

Anonymizer

An anonymizer attempts to make Internet activity untraceable. It hides the client computer’s identifying information by inserting a proxy server computer between the client computer and the rest of the Internet.

Anti-Virus Software

Anti-Virus Software detects, prevents, and removes viruses, worms, and other malware from a device. Anti-virus programs typically include an auto-update feature so that updated profiles of new threats can be downloaded, enabling the system to identify new threats. One anti-virus program might find a certain virus or worm while another cannot, or vice-versa.

Authentication

Authentication is the process that ensures and confirms a user’s identity. It may require a username and password, or biometrics (such as a fingerprint). Two-factor authentication requires a combination of two different factors: 1) something the user knows (e.g., password), 2) something the user has (e.g., ATM card), or 3) something the user is (e.g., fingerprint).

 

B

BitTorrent

BitTorrent is a protocol that makes downloading large files faster on peer-to-peer (P2P) file-sharing networks.  Downloading a large file from one source can be very slow, so the BitTorrent system will locate multiple computers with the same file and download it in parts from several computers at once.

Bot

A bot is malware that allows an attacker to take control over an infected computer. Bots are usually part of a network of infected machines, called a “botnet.” Botnets might involve a few thousand computers, but others consist of tens or even hundreds of thousands of infected devices. If your computer is part of a botnest, it might slow down, display mysterious messages, or even crash.

Brushing

Brushing is a technique sometimes used to boost an online seller’s ratings by creating fake orders and reviews. The scammer creates fake accounts and has products sent to real people. The scammer then leaves reviews using the names on the fake customer accounts to artificially boost their products.

Brute force attack

A brute force attack is a trial and error method used by application programs to decode encrypted data such as passwords or Data Encryption Standard (DES) keys, through exhaustive effort (using brute force). The hacker uses millions of user ID and password combinations in an attempt to find one that works.

Denial of Service (DOS)

A Denial of Service (DOS) attack involves hackers attempting to prevent legitimate users from accessing a website or online service. In a DoS attack, the attacker usually sends excessive messages asking the network or server to authenticate requests that have invalid return addresses, thus tying up the network’s resources.

The EFTA provides protections such as allowing consumers to have errors corrected within a 45-day period with limited financial penalties.

Such metadata may include the exposure time (shutter speed), f-number (aperture), ISO setting, flash (on/off), and the date and time.  Many smartphones and some newer digital cameras also include GPS information, which is used for “geotagging” photos with the location where the photo was taken. EXIF is supported by both the TIFF and JPEG image formats, and is commonly found in JPEG images captured with digital cameras.

 

F

G

 

Geotag

A geotag is metadata that contains geographic information. For example, photo geotags may include latitude, longitude, altitude, compass bearing and other attributes. Smartphones and many cameras automatically geotag photos, or tags may be added manually.

Geofencing

Geofencing uses GPS, RFID, Wi-Fi or cellular data to trigger a pre-programmed action when a mobile device or RFID tag enters or exits a virtual boundary set up around a geographical location, known as a geofence. For example, an app may display a coupon when a customer enters within a certain range of a retail location.

Grandparent Scam

In the Grandparent Scam, the scammer contacts the victim posing as a relative or someone claiming to represent the relative (such as a lawyer or law enforcement agent).

Money Laundering

Money Laundering involves disguising the proceeds from illegal activities so they can be used without detection of the criminal activity that produced them. Through a series of transactions, often involving persons who are unaware of the source of the money, the criminal transforms the illegally obtained money into funds with an apparently legal source.

 

N

 

Nigerian 419 Scams

Nigerian 419 Scams start with a letter or email offering the victim the “opportunity” to share in millions of dollars that the scammer—a self-proclaimed government official—is trying to transfer illegally out of Nigeria.

Sniffing

Packet sniffing captures data as it is transmitted over a network. It may be used by system administrators to diagnose network issues, and by malicious users to capture unencrypted data, like passwords and usernames.

Social Engineering

Social Engineering involves manipulating people so they give up confidential information, such as passwords or bank information, or allow access so the bad guys can install malicious software. Social engineering takes advantage of the fact that the weakest link in any security system is the human operator.

Synthetic identity theft
