If your smartphone seems to be acting up—perhaps bombarding you with random pop-ups or displaying unfamiliar apps—these could be red flags of malware. Here are six clear signs of malware that I’ve personally encountered, which could help you identify if your phone is infected.

Key Takeaways​

• Unusually high data usage or battery drain often indicates malware running in the background, leaking data to third parties.
• Random pop-up ads or unfamiliar apps installing themselves on your smartphone could signal an adware infection.
• Overheating, lagging, frequent reboots, or performance issues while performing basic tasks are also telling signs of malware infection.

Device Integrity also is widely overlooked. A simple root check also isn't good enough. I've dealt with cases of VIP mobile devices being compromised with zero malware detected by App based antiviruses. Only indicators were device integrity metrics.

In these cases the devices were imaged to be analyzed whilst the VIP would have a brand new device provisioned, identity reset (and investigated), root cause determined (if possible), and security strategy adapted.
