Afür dessen Entschlüsselung mehrere hundert US-Dollar gefordert wurden. Seine Tarnung als reguläre Applikation legt aber eher eine Kategorisierung als Trojaner nahe. Meine Wortlisten.
Programs are also considered malware if they secretly act against the interests of the computer user. For example, at one point Sony music Compact discs silently installed a rootkit on purchasers' computers with the intention of preventing illicit copying, but which also reported on users' listening habits, and unintentionally created extra security vulnerabilities.
A range of antivirus software , firewalls and other strategies are used to help protect against the introduction of malware, to help detect it if it is already present, and to recover from malware-associated malicious activity and attacks.
Many early infectious programs, including the first Internet Worm , were written as experiments or pranks.
Malware is sometimes used broadly against government or corporate websites to gather guarded information,  or to disrupt their operation in general.
However, malware can be 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 , the majority of widespread viruses and worms have been designed to take control of users' computers for illicit purposes.
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. Ransomware affects an infected computer system in some way, and demands payment to bring it back to its normal state.
There are two variations of ransomware, being crypto ransomware and locker ransomware. Whereas the traditional ransomware is one that locks down a system and encrypts its contents.
For example, programs such as CryptoLocker encrypt 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.
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 which spread over and shut down large computer networks, including massive deletion of files and corruption of master boot records , described as "computer killing.
Disttrack and Saudi Aramco August The best-known types of malware, viruses and worms, are known for the manner in which they spread, rather than any specific types of behavior.
A computer virus is software that embeds itself in some other executable software including the operating system itself on the target system without the user's knowledge and consent and when it is run, the virus is spread to other executables.
On the other hand, a worm is a stand-alone malware software 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 software or operating system for the virus to spread, whereas a worm spreads itself.
These categories are not mutually exclusive, so malware may use multiple techniques. A computer virus is software usually hidden within another seemingly innocuous program that can produce copies of itself and insert them into other programs or files, and that usually performs a harmful action such as destroying data.
A Trojan horse is a harmful program that misrepresents itself to masquerade as a regular, benign program or utility in order to persuade a victim to install it.
A Trojan horse usually carries a hidden destructive function that is activated when the application is started.
The term is derived from the Ancient Greek story of the Trojan horse used to invade the city of Troy by stealth. 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.
Unlike computer viruses and worms, Trojan horses generally do not attempt to inject themselves into other files or otherwise propagate themselves.
In spring Mac users were hit by the new version of Proton Remote Access Trojan RAT  trained to extract password data from various sources, such as browser auto-fill data, the Mac-OS keychain, and password vaults.
Once malicious software 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 host's operating system so that the malware is hidden from the user.
Rootkits can prevent a harmful process from being visible in the system's list of processes , or keep its files from being read.
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:.
A 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,  invisibly to the user.
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 that 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.
Since the beginning of , a sizable portion of malware has been utilizing a combination of many techniques designed to avoid detection and analysis.
An increasingly common technique is adware that uses stolen certificates to disable anti-malware and virus protection; technical remedies are available to deal with the adware.
Nowadays, one of the most sophisticated and stealthy ways of evasion is to use information hiding techniques, namely stegomalware.
A survey on stegomalware was published by Cabaj et al. Fileless malware does not require a file to operate.
It runs within memory and utilizes existing system tools to carry out malicious acts. Because there are no files on the system, there are no executable files for antivirus and forensic tools to analyze, making such malware nearly impossible to detect.
The only way to detect fileless malware is to catch it operating in real time. Such attacks are not easy to perform but are becoming more prevalent with the help of exploit-kits.
Malware exploits security defects security bugs or vulnerabilities in the design of the operating system, in applications such as browsers, e.
Security advisories from plug-in providers announce security-related updates. Secunia PSI  is an example of software, free for personal use, that will check a PC for vulnerable out-of-date software, and attempt to update it.
Malware authors target bugs , or loopholes, to exploit. A common method is exploitation of a buffer overrun vulnerability, where software designed to store data in a specified region of memory does not prevent more data than the buffer can accommodate being supplied.
Malware may provide data that overflows the buffer, with malicious executable code or data after the end; when this payload is accessed it does what the attacker, not the legitimate software, determines.
Early PCs had to be booted from floppy disks. It was common to configure the computer to boot from one of these devices when available.
Normally none would be available; the user would intentionally insert, say, a CD into the optical drive to boot the computer in some special way, for example, to install an operating system.
Even without booting, computers can be configured to execute software on some media as soon as they become available, e. Malware distributors would trick the user into booting or running from an infected device or medium.
For example, a virus could make an infected computer add autorunnable code to any USB stick plugged into it. Anyone who then attached the stick to another computer set to autorun from USB would in turn become infected, and also pass on the infection in the same way.
Devices can be infected during manufacturing or supply if quality control is inadequate. This form of infection can largely be avoided by setting up computers by default to boot from the internal hard drive, if available, and not to autorun from devices.
Users may also execute disguised malicious email attachments. In computing, privilege refers to how much a user or program is allowed to modify a system.
In poorly designed computer systems, both users and programs can be assigned more privileges than they should have, and malware can take advantage of this.
The two ways that malware does this is through overprivileged users and overprivileged code. Some systems allow all users to modify their internal structures, and such users today would be considered over-privileged users.
This was the standard operating procedure for early microcomputer and home computer systems, where there was no distinction between an administrator or root , and a regular user of the system.
In some systems, non-administrator users are over-privileged by design, in the sense that they are allowed to modify internal structures of the system.
In some environments, users are over-privileged because they have been inappropriately granted administrator or equivalent status.
Some systems allow code executed by a user to access all rights of that user, which is known as over-privileged code.
This was also standard operating procedure for early microcomputer and home computer systems. Crvi se mogu podijeliti i u druge kategorije  :.
Trojanski konji nemaju komponentu samorepliciranja za razliku od crva i virusa, tako da ih korisnici sami moraju kopirati.
