f you're an Android user, you might want to get your phone checked out.
Researchers found malware nicknamed 'HummingBad' has hit 10 million Android phones, included more than 260,000 in the U.S., Ars Technica reports.
The malware has shown 20 million unwanted ads and generates more than $300,000 each month. It mostly affects older versions of Android OS, particularly KitKat.
A report from security researchers Check Point traced the malware to a Chinese mobile ad server company called Yingmob.
Check Point researchers said the malware allows its maker to "sell access to these devices to the highest bidder."
Here's how the malware hits your phone:
"Drive-by downloads," or when you download a program without knowing it
Forcibly "rooting" your phone. Power users who want to make their phone extremely customizable often root their phones, but it can give apps unwanted access to critical parts of the phone.
Giving a fake system update that gives permission to HummingBad malware to do whatever it wants
The easiest way to prevent this? Change your settings so that you can only install apps from the Google Play store.
To see if you have HiummingBad, you can download anti-malware apps like Zone Alarm and Avast. If you have HummingBad, there's only one solution unless you're a cybersecurity genius: a factory reset of the phone, CNET reports.
