They can store and process a lot of data that may be breached by theft or data leakage. This study deals with the overview of the main attacks that can be performed using the vulnerabilities of a mobile device with inserted software bug. This bug can force the phone to send text messages, make calls on paid numbers and record them, get access to private information (list of contacts, text) as well as harm the operating system. Researchers also provide the basic recommendation the following of which will protect the user from the unlawful action of an intruder using the malicious logic. The overview can be used to improve existing mobile security means. Keywords: malicious logic;mobile device vulnerabilities;Software bug;unauthorized access;action
