Malware: what is it?

The word itself is short for “malicious software”. It is defined as any software created with the intention of causing damage to a device without the owner’s knowledge or consent.

While malware has been around for decades, mobile malware is a relatively new concern. Asking security experts if mobile malware was a risk back in 2014 would have resulted in mixed responses. In 2017, the answer is a resounding yes. Mobile malware is a potent and growing threat to enterprise.
