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.
Regin (malware)
Symantec says that both it and Kaspersky identified the malware as "Backdoor. Regin". Most antivirus programs, including Kaspersky, (as of October 2015) do NOT identify the sample of Regin released by The Intercept as malware. On 9 March 2011 Microsoft added related entries to its Malware Encyclopedia; later two more variants, "Regin. B" and "Regin. C" were added. Microsoft appears to call the 64-bit variants of Regin "Prax. A" and "Prax. B". The Microsoft entries do not have any technical information. Both Kaspersky and Symantec have published white papers with information they learned about the malware.
