Explanation
Mobile malware is a malicious software specifically designed to target mobile devices such as smartphones and tablets. The primary purpose of this type of malware is to exploit vulnerabilities in the mobile operating systems and their applications to gain unauthorized access to sensitive data, take control over device functionalities or inject malicious code.
Cybercriminals use various tactics, from disguising malware as seemingly legitimate applications to exploiting known security flaws in operating systems, in order to infect a device and achieve their nefarious objectives. Once a mobile device is infected with malware, it can be used for multiple purposes, depending on the cybercriminal’s intent.
Some common uses of mobile malware include data-mining to steal personal and financial information, launching Distributed Denial of Service (DDoS) attacks, sending premium-rate SMS messages without the user’s consent, encrypting content on the device for a ransomware attack or using it as a bot within a larger botnet attack. As mobile devices continue to become more ingrained in our daily lives, the threat of mobile malware increases, prompting a need for stronger security measures and increased awareness among users to protect their personal data and ensure the safe use of these devices.
Examples of Mobile Malware
Android Backdoor GhostCtrl: Discovered in 2017, GhostCtrl is a mobile malware that targets Android devices. It poses as a legitimate application (like WhatsApp or Pokemon Go) and tricks users into installing it. Once installed, the malware gains root access and takes control of basic functions, enabling it to access users’ contacts, camera, microphone, and messages. The malware employs various tactics like allowing hackers to record video and audio, steal private data, and even lock the device.
Judy Malware: Judy is an Android-based mobile malware discovered in 2017, which had infected over
5 million devices. The malware came disguised as a variety of seemingly harmless gaming apps. Once installed, the infected apps generated fraudulent clicks on advertisements displayed within the app to generate revenue for the attackers. Judy was found to be distributed through Google Play Store, highlighting the vulnerability of even official app sources to such malicious actors.
iKee Worm: The iKee Worm, discovered in 2009, is an example of mobile malware that targeted iPhones. It exploited a vulnerability in jailbroken iPhones where users had not changed the default password for Secure Shell protocol. The worm changed the wallpaper on the infected iPhone to an image of the 80s pop singer Rick Astley with the message “ikee is never going to give you up.” More importantly, it exposed the device to further security risks, as it enabled remote control for hackers to execute commands and steal sensitive information.
