Malware Wikipedia. Malware, short for malicious software, is an umbrella term used to refer to a variety of forms of hostile or intrusive software,1 including computer viruses, worms, Trojan horses, ransomware, spyware, adware, scareware, and other malicious programs. It can take the form of executable code, scripts, active content, and other software. 2 Malware is defined by its malicious intent, acting against the requirements of the computer user and so does not include software that causes unintentional harm due to some deficiency. Programs supplied officially by companies can be considered malware if they secretly act against the interests of the computer user. An example is the Sony rootkit, a Trojan horse embedded into CDs sold by Sony, which silently installed and concealed itself on purchasers computers with the intention of preventing illicit copying it also reported on users listening habits, and unintentionally created vulnerabilities that were exploited by unrelated malware. 3Software such as anti virus and firewalls are used to protect against activity identified as malicious, and to recover from attacks. 4Purposesedit.

Malware by categories on 1. March 2. 01. 1. Many early infectious programs, including the first Internet Worm, were written as experiments or pranks. Today, malware is used by both black hat hackers and governments, to steal personal, financial, or business information. 56Malware is sometimes used broadly against government or corporate websites to gather guarded information,7 or to disrupt their operation in general. However, malware is often used against individuals to gain information such as personal identification numbers or details, bank or credit card numbers, and passwords. Since the rise of widespread broadband. Internet access, malicious software has more frequently been designed for profit. Since 2. 00. 3, the majority of widespread viruses and worms have been designed to take control of users computers for illicit purposes. 8 Infected zombie computers are used to send email spam, to host contraband data such as child pornography,9 or to engage in distributed denial of serviceattacks as a form of extortion. 1. Programs designed to monitor users web browsing, display unsolicited advertisements, or redirect affiliate marketing revenues are called spyware. Spyware programs do not spread like viruses instead they are generally installed by exploiting security holes. They can also be hidden and packaged together with unrelated user installed software. 1. Ransomware affects an infected computer in some way, and demands payment to reverse the damage. For example, programs such as Crypto. Malware, short for malicious software, is an umbrella term used to refer to a variety of forms of hostile or intrusive software, including computer viruses, worms. Lockerencrypt files securely, and only decrypt them on payment of a substantial sum of money. Some malware is used to generate money by click fraud, making it appear that the computer user has clicked an advertising link on a site, generating a payment from the advertiser. It was estimated in 2. In addition to criminal money making, malware can be used for sabotage, often for political motives. Stuxnet, for example, was designed to disrupt very specific industrial equipment. There have been politically motivated attacks that have spread over and shut down large computer networks, including massive deletion of files and corruption of master boot records, described as computer killing. Such attacks were made on Sony Pictures Entertainment 2. November 2. 01. 4, using malware known as Shamoon or W3. Disttrack and Saudi Aramco August 2. Infectious malwareeditThe best known types of malware, viruses and worms, are known for the manner in which they spread, rather than any specific types of behavior. The term computer virus is used for a program that embeds itself in some other executable software including the operating system itself on the target system without the users consent and when that is run causes the virus to spread to other executables. On the other hand, a worm is a stand alone malware program that actively transmits itself over a network to infect other computers. These definitions lead to the observation that a virus requires the user to run an infected program or operating system for the virus to spread, whereas a worm spreads itself. 1. ConcealmenteditThese categories are not mutually exclusive, so malware may use multiple techniques. 1. This section only applies to malware designed to operate undetected, not sabotage and ransomware. ViruseseditA computer program usually hidden within another seemingly innocuous program that produces copies of itself and inserts them into other programs or files, and that usually performs a malicious action such as destroying data. 1. An example of this is a PE infection, a technique, usually used to spread malware, that inserts extra data or executable code into PE files. 1. Lock screenseditLock screens, or screen lockers is a type of cyber police ransomware that blocks screens on Windows or Android devices with a false accusation in harvesting illegal content, trying to scare the victims into paying up a fee. 1. Jisut and SLocker impact Android devices more than other lock screens, with Jisut making up nearly 6. Android ransomware detections. 2. Trojan horseseditA Trojan horse is a malicious computer program which misrepresents itself to appear useful, routine, or interesting in order to persuade a victim to install it. The term is derived from the Ancient Greek story of the Trojan horse used to invade the city of Troy by stealth. 2. Trojan horses are generally spread by some form of social engineering, for example where a user is duped into executing an e mail attachment disguised to be unsuspicious, e. Although their payload can be anything, many modern forms act as a backdoor, contacting a controller which can then have unauthorized access to the affected computer. 2. While Trojan horses and backdoors are not easily detectable by themselves, computers may appear to run slower due to heavy processor or network usage. Unlike computer viruses and worms, Trojan horses generally do not attempt to inject themselves into other files or otherwise propagate themselves. 2. In spring 2. 01. 7 Mac users were hit by the new version of Proton Remote Access Trojan RAT2. Mac OS keychain, and password vaults. 2. RootkitseditOnce a malicious program is installed on a system, it is essential that it stays concealed, to avoid detection. Software packages known as rootkits allow this concealment, by modifying the hosts operating system so that the malware is hidden from the user. Rootkits can prevent a malicious process from being visible in the systems list of processes, or keep its files from being read. 3. Some malicious programs contain routines to defend against removal, not merely to hide themselves. An early example of this behavior is recorded in the Jargon File tale of a pair of programs infesting a Xerox CP V time sharing system Each ghost job would detect the fact that the other had been killed, and would start a new copy of the recently stopped program within a few milliseconds. The only way to kill both ghosts was to kill them simultaneously very difficult or to deliberately crash the system. 3. BackdoorseditA backdoor is a method of bypassing normal authentication procedures, usually over a connection to a network such as the Internet. Once a system has been compromised, one or more backdoors may be installed in order to allow access in the future,3. The idea has often been suggested that computer manufacturers preinstall backdoors on their systems to provide technical support for customers, but this has never been reliably verified. It was reported in 2. US government agencies had been diverting computers purchased by those considered targets to secret workshops where software or hardware permitting remote access by the agency was installed, considered to be among the most productive operations to obtain access to networks around the world. 3. Backdoors may be installed by Trojan horses, worms, implants, or other methods. 3. EvasioneditSince the beginning of 2. The most common evasion technique is when the malware evades analysis and detection by fingerprinting the environment when executed. 3. The second most common evasion technique is confusing automated tools detection methods. This allows malware to avoid detection by technologies such as signature based antivirus software by changing the server used by the malware. 3. List of freeware Wikipedia. Freeware is software that is available for use at no monetary cost or for an optional fee,1 but usually although not necessarily closed source with one or more restricted usage rights. Freeware is in contrast to commercial software, which is typically sold for profit, but might be distributed for a business or commercial purpose in the aim to expand the marketshare of a premium product. Popular examples of closed source freeware include Adobe Reader, Free Studio and Skype.
