Unit 39 Malware Malware, a portmanteau word from the words malicious and software, is software designed to infiltrate or damage a computer system without the owner s informed consent. The expression is a general term used by computer professionals to mean a variety of forms of hostile, intrusive, or annoying software or program code. Many computer users are unfamiliar with the term, and often use computer virus for all types of malware, including true viruses. Software is considered malware based on the intent of the creator rather than any particular features. Malware includes computer viruses, worms, Trojan horses, most rootkits, spyware, dishonest adware, crimeware and other malicious and unwanted software. Many early infectious programs, including the first Internet worm and a number of MS-DOS viruses, were written as experiments or pranks generally intended to be harmless or merely annoying rather than to cause serious damage to computers. In some cases the perpetrator did not realise how much harm their creations could do. Young programmers learning about viruses and the techniques used to write them only to prove that they could create a virus or to see how far it could spread. As late as 1999, widespread viruses such as the Melissa virus appear to have been written chiefly as pranks. However, since the rise of widespread broadband Internet access, malicious software has come to be designed for a profit motive, either more or less legal (forced advertising) or criminal. The majority of widespread viruses and worms have been designed to take control of users computers for black-market exploitation. Another strictly for-profit category of malware has emerged in spyware programs designed to monitor users web browsing or display unsolicited advertisements. Spyware programs do not spread like viruses; they are generally installed by exploiting security holes in operating systems or are packaged with user-installed software, such as peer-to-peer applications. Installing a spyware program takes just a few seconds. It is not uncommon for spyware and advertising programs to install so many processes that the infected computer becomes unusable, defeating the intentions of attackers. portmanteau word VáRZRSo- ZVWDáH]SRáF]HQLDLnQ\FKVáyZ malicious ]árolz\ consent zgoda, przyzwolenie hostile wrogi intrusive QLHSR*GDQ\ unfamiliar nieobeznany intent intencja, zamiar Trojan horse NR WURMDVNL crime SU]HVWSVWZR prank SVLNXVJáXSL*DUW merely tylko, jedynie perpetrator sprawca chiefly JáyZQLH broadband szerokopasmowy forced advertising nachalna reklama strictly Z\áF]QLH unsolicited nie zamówiony exploit Z\NRU]\VW\ZDü defeat SRUD*NDQLHSRZRG]HQLH 240

The term computer virus is used for a program which has infected some executable software and which causes that software, when run, to spread the virus to other executable software. Viruses may also contain a payload which performs other actions, often malicious. A worm, on the other hand, is a program which actively transmits itself over a network to infect other computers. A virus requires user intervention to spread, whereas a worm spreads automatically. Trojan Horses A Trojan horse is any program that invites the user to run it, but conceals a harmful or malicious payload. The payload may take effect immediately and can lead to many undesirable effects, such as deleting all the user s files, or more commonly it may install further harmful software into the user s operating system to serve the creator s longer-term goals. Rootkits Once a malicious program is installed on a system, it is often useful to the creator if it stays concealed. The same is true when a human attacker breaks into a computer directly.

3 concealment, by modifying the host operating system so that the malware is hidden from the user. Rootkits can prevent a malicious process from being visible in the system's list of processes, or keep their files from being read. Originally, a rootkit was a set of tools installed by a human attacker on a Unix system where the attacker had gained administrator (root) access. Today, the term is used more generally for concealment routines in a malicious program. Backdoors A backdoor is a method of bypassing normal authentication procedures. Once a system has been compromised in some way, one or more backdoors may be installed, in order to allow the attacker access in the future. Crackers typically use backdoors to secure remote access to a computer, while attempting to remain hidden from casual inspection. To install backdoors crackers may use Trojan horses, worms, or other methods. concealment ukrywanie, maskowanie, utajnianie root NRU]H(UyGáR concealment routine procedura ukrywania backdoor tylne drzwi authentication identyfikacja cracker NUDNHUZáDP\ZDF] casual przypadkowy, dorywczy Zwroty to infiltrate without the owner s informed consent LQILOWURZDüEH]]JRG\LZLHG]\X*\WNRZQLND to base on the intent of the creator ED]RZDüQDLQWHQFMLWZyUF\ the strictly for-profit category of malware NDWHJRULD PDOZDUH SU]H]QDF]RQD Z\áF]QLH GR RVLJQLFLD]\VNX packaged with user-installed software XNU\W\ZSURJUDPLHLQVWDORZDQ\PSU]H]X*\WNRZQLND to defeat the intentions of attackers QLZHF]\ü]DPLDU\DWDNXMF\FK to be installed on an operating system E\ü zainstalowanym w systemie operacyjnym to hide from the user XNU\üSU]HGX*\WNRZQLNLHP 2EMDQLHQLD P2P (od peer-to-peer równy z równym) model komunikacji w sieci komputerowej, który JZDUDQWXMHRE\GZXVWURQRPUyZQRU]GQHSUDZDZSU]HFLZLHVWZLHGRPRGHOXNOLHQWVHUZHU :VLHFLDFK33ND*G\NRPSXWHUPR*HMHGQRF]HQLHSHáQLü]DUyZQRIXQNFMNOLHQWDMDNLVHrwera.

Malware is not the same as defective software, that is, software which has a legitimate purpose but contains harmful bugs. 2. For a malicious program to accomplish its goals, it must be able to do so without being shut down, or deleted by the user or administrator of the computer it s running on. 3. Before Internet access became widespread, viruses spread on personal computers by infecting programs or boot sectors of floppy disks. 4. Many DOS viruses and Windows worms were designed to destroy files on a hard disk, or to corrupt the file system by writing junk data. 5. Anti-spyware programs can be used solely for detection and removal of malware software that has already been installed onto your computer. 6. The first antivirus programs combated only computer viruses, and modern antivirus software can protect computers against a wide range of malware, including worms, rootkits, and Trojans. 245
