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.

In September 2018, the Unit 42 discovered Xbash, a ransomware that also performs cryptomining, believed to be tied to the Chinese threat actor "Iron". Xbash is able to propagate like a worm and deletes databases stored on victim hosts. In October, Unit 42 warned of a new cryptomining malware, XMRig, that comes bundled with infected Adobe Flash updates. The malware uses the victim's computer's resources to mine Monero cryptocurrency.
