8 Signs of a Smartphone Hack

A rapidly dwindling battery life or sudden spike in data usage could indicate your iOS or Android device has been compromised.

Sudden Loss of Battery Life
A sharp increase in battery usage could indicate a compromise. Some malware commonly seen on Android devices, for example, will launch a service in the background to quietly consume data like GPS location without users' knowledge.
'Quickly, your phone goes from lasting the entire day to nearly running out of power by lunchtime,' says Stephen Banda, senior manager of security solutions at Lookout. 'With no other reason for this, it's likely that malware exists on the phone and is running processes that consume battery power.'
You can check for this by opening battery settings on your iOS or Android device and reviewing how much power different apps consume. Checking the percentages can help determine any offending applications so they can be deleted.

tl;dr version
For those of us that still think articles can be written in full on a single page, rather than having to click through multiple pages, here's the tl;dr version:

1. Sudden Loss of Battery Life
2. Excessive App Permissions
3. Your Account Is Sending Messages, But You Aren't
4. Suspicious Texts and Unknown Websites
5. Spike in Data Usage
6. Key Passwords No Longer Work
7. Not All Attackers Leave a Trace (Use a private VPN)
8. Don't reuse passwords, use antimalware/antivirus apps, keep apps up to date, etc.

Smartphone/Easy Target
Smartphones carry more risk than most think of.  Even with a BYOD in place at work it still dosnt protect form data being siphoned off of personal use.  With everything we keep in our phones.  Sure some only have a phone book and little more but that might be all that was needed.
