Malicious software, known as malware, is not only a threat to your computer. Smartphones are targets too, particularly those using the Android operating system.
Mobile security giant Lookout has posted a checklist: How to Tell if Your Phone Has Been Hacked
Five key clues
1. Is battery is running out of juice extremely fast? Malware apps may be running constantly in the background, causing your smartphone battery to drain much faster than normal.
2. Is your phone sending or receiving strange text messages?
3. Does your phone bill include strange or unknown charges?
4. Does your call history include long-distance calls you didn’t make?
5. Does your phone go haywire, strangely opening apps or do the apps no longer work properly or open up by themselves?
If you answered yes to some or all of these questions, your device might be compromised and you might want to run a security scan.
To keep your mobile safe from malware, Lookout advises you to keep the software on your device up to date and to stick to official app stores when downloading apps.
