Even though here at SDTEK our focus is providing managed it services for small to medium companies, we do like to help bring awareness to all sorts of security risks to any type of device. It’s probably pretty safe to say we can’t do without smartphones. Whether it is for personal use, entertainment, connecting with friends and family, or business management, mobile phones are an essential part of modern life.
Nonetheless, the freedoms to connect and engage with others through mobile phones can be threatened by the spread of mobile malware. This form of malware is something that is not really spoken about as much as let’s say keeping a computer network safe. However, it is important and we hope by shedding some light on this topic that you will find this blog post to be a helpful resource.
What is Mobile Malware?
Mobile malware is malicious code designed to attack and spread to mobile or smartphones by leveraging operating system vulnerabilities to infect system and application software. Essentially it is a cyber attack directed to your phone.
Many people are familiar with the computer virus but little is known about mobile malware. This makes them more destructive since they can operate undetected for a long time.
Your smartphone may be working fine while malware is busy stealing your data. Android is the most targeted operating system since it holds the largest market share.
Mobile malware may steal victims’ personal data, create a backdoor to the OS or carry out unauthorized financial transactions and communications without the owner’s knowledge.
Mobile Malware’s Threat to Cyber Security
Mobile devices are targeted because they are often not as secured as PCs and desktops. Moreover, enterprise mobile device security solutions and policies are often challenging to install or enforce.
Many devices on the Android platform often run outdated software that is easier to hack. Some iPhone users also don’t upgrade their devices as long as it is working making them a target of malware.
Hackers can also use mobile device’s lax security to indirectly attack businesses which might be difficult to breach.
