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.
Watering hole attack
From August to September 2017 the installation binary of Ccleaner distributed by the vendor's download servers included malware. Ccleaner is a popular tool used to clean potentially unwanted files from Windows computers, widely used by security-minded users. The distributed installer binaries were signed with the developer's certificate making it likely that an attacker compromised the development or build environment and used this to insert malware.
