If your Android phone runs hot, slow and has poor battery life, it could be a cryptojacking victim
If your Android phone is lagging, losing battery life too quickly, or is overheating often, it might have been hijacked by a cryptocurrency miner. These are the guys and gals who are figuring out complex problems to earn a new Bitcoin, or one of several other virtual currencies. These mathematical problems, used to verify cryptocurrency transactions, require serious processing power, more than what is available from a single smartphone.

So the latest scam involves cryptocurrency miners taking control of multiple Android smartphones and linking their processing power. This is accomplished by having unsuspecting smartphone users install an app that has malicious software inside. Researchers at IT security firm ESET discovered that Bug Swasher, a game loaded from the Google Play Store between 1 million and 5 million times, was mining cryptocurrency without the knowledge of those who installed the game on their phones. A word has been coined for these types of attacks, "cryptojacking."


In July, Google announced that it was banning all cryptocurrency mining apps from the Play Store. But not even Google knows exactly which apps are a Trojan Horse for miners. The problem is that because of the processing power required for mining, a hijacked phone could end up with a bloated battery. And in the worse case scenario, an entire handset can be permanently damaged.

For protection from these hackers, fraud expert Laurent Petroque says that Android users should make sure that they have the latest version of the OS available for their phones, load an anti-virus program, and never sideload an app from a non-official source.

Or maybe its all the junk google is tracking, I wish Windows Mobile 10 would have been more popular. It was an awesome OS.

Google Play Protect got 0 in AV-test & they are serious about security.

That's bulls**t test, those AV makers just want to sell their useless AV. As long as you didn't download APK from some random source and just stick to well-known apps from google play, you'll be fine.

Nah, it's because it's hot outside. Not because you're being hacked. And if anything, go into your settings and it'll tell you what apps are using your battery.

https://9to5mac.com/2017/12/21/hands-on-mobileminer-how-to-mine-cryptocurrency-on-an-iphone-video/ Not the same thing, but some one could put it into an app and have it get passed the App Store regulations. Or lure someone into doing it outside of the store.

It's not cryptojacking, and I'm not looking for empty theories (you think an app with a miner would get accepted?). Still waiting for a source that iPhones can, or have been, 'cryptojacked'. If speedingcheetah was making baseless assumptions because Android has egg on the face, I'll accept that answer too.

Bro they had jailbreaking apps in the app store within the last couple of years. It could happen. Apple is stricter now, but it could happen (but definitely not as easily as Android)

typical Apple Fan Boy reply. Apple has had plenty of bad apps in their app store, some so bad they cause the phone to overheat and battery to swell and burst, crytpomining or not. And terrible security issues of late....like root access with no password. lol. good one Apple. They where in the news for crypto and malware apps before, same as Android. I have had to help out plenty stupid customers clean up their phones full of crap apps all day long working in a phone store. Get a Win phone, u wont have any issues, cause no one cares to make apps for that platform anymore. LOL!

Damn so it crytojacking that made my Shield Tablet K1 run so hot, and laggy. Nvidia Shield Tablet K1 aged worst compared to my other Android devices.
