Mobile security
As smartphones are a permanent point of access to the internet (mostly on), they can be compromised as easily as computers with malware. A malware is a computer program that aims to harm the system in which it resides. Trojans, worms and viruses are all considered malware. A Trojan is a program that is on the smartphone and allows external users to connect discreetly. A worm is a program that reproduces on multiple computers across a network. A virus is malicious software designed to spread to other computers by inserting itself into legitimate programs and running programs in parallel. However, it must be said that the malware are far less numerous and important to smartphones as they are to computers.
Boot sector
As an example, the malware [[Petya (malware)|NotPetya]] attempts to gain administrative privileges on an operating system, and then would attempt to overwrite the boot sector of a computer. The [[Central Intelligence Agency|CIA]] has also developed malware that attempts to modify the boot sector in order to load additional drivers to be used by other malware.
