Point-of-Sale A Point-of-Sale attack is malware designed to steal sensitive information from POS systems. Stolen information from credit cards is considered as the goal of a major POS attack. POS systems are the popular target for the criminals because of their role to process financial transactions. Small businesses without having an advanced information security resources to secure their retail environments  are at increased attack. A company was attacked with POS malware in 2013, which is considered as one of the major attacks in the recent years.

SQL injection is technique that exploits a security vulnerability occurring in the application and/or database layer of an application. The vulnerability is present when user input (typically via HTML forms0 is either not validated or incorrectly filtered for string literal escape characters embedded in SQL (structured query language) statements. It is an instance of a more general class of vulnerabilities that can occur whenever one programming or scripting language is embedded inside another. Source: FEMA (TEEX)

Session Hijacking Session Hijacking refers to the exploitation of a valid computer session via theft of a cookie or session key, used to gain unauthorized access to information or services. When an attacker is able to steal the cookie containing session access data, (s)he can make requests as if (s)he were the actual user.

Advanced Persistent Threat (APT) is a long-term targeted attack on a system. At first, it penetrate a network without interruption of the regular services and then collects valuable information over a long period of time. This type of threat is categorized as highly complex because they are persistent, evasive, and targeted in comparison with the traditional attack. As these are advanced threats, the entire process of stealing information may take many years. One of the most common example of an APT is Stuxnet. Source: FEMA (TEEX)

A backdoor into an information system s a method of bypassing normal user identification and authentication while securing access to that system. Often a computer programmer will install a backdoor into a software application or component so that (s) he can gain access into the system without the system recording who (s) he is. A backdoor can be created without modifying the source code of a program by rewriting the complier so that it recognizes code during compilation that triggers inclusion of a backdoor.

A time bomb is a computer program that will cease to function after a predetermined date or time is reached. Time bombs are often set by application developers to extort money or other compensation from former employers. They are also set by software developing organizations so that software will no longer function after a license period has expired. The term "time bomb" should not be applied to a declared trial application program that stops functioning a specific number of days after it is installed. In such a cause, the term "trialware" applies. Source: FEMA TEEX
