The app offers the premium features for accessing the CPU power to mine cryptocurrency
Apple Mac Store is hosting an app that mines the cryptocurrency via user’s Mac devices. The Calendar 2 app on the Mac mines the virtual currency in the background in return for some additional features for the users. The app offers premium facilities and asks permission to access the CPU power for mining the cryptocurrency. Apple didn't put down the app from the Mac App Store yet.
Calendar 2 is a smarter replacement for Apple’s default calendar app for the macOS. On breaking down the codes it was found that the app asks the users to get premium features in return for certain permissions. Once the user accepts the offer and allows the app to access CPU’s power it starts mining the Monero. The app belongs to Qbix, who added the code for mining the virtual currency. Monero, launched back in 2014 is a cryptocurrency like bitcoin but with benefits of anonymity. This means the transactions are not available on the public ledger. Recently, the monero has become preferable for the miners as its algorithms are more CPU compatible.
The app provides some of its premium features to users for mining the cryptocurrency in return. The users can also access these features by paying the cost in the App Store doing which is supposed to stop the app from mining monero. However, there are two bugs in the app, the first one continues the mining process even if the users opt out. The second bug causes the app to drain more resources than planned. Qbix said that the team is working on the bugs and will come up with the fixes very soon.
The scheduling app isn't the first one to come up as a crypto miner in the Apple’s App Store. However the approach is different, calendar 2 app openly asks the users to allow crypto mining as payment for its premium features, which is kind of grey zone activity as compared to other miners. Qbix uses monero mining as the way to earn from its non-paying users.
In Spite of acknowledging the users about crypto mining using their CPU power, the app still violates Apple’s guideline stating,” Apps should not rapidly drain battery, generate excessive heat, or put unnecessary strain on device resources.”
