A calendar application in the Mac App Store has been extracting cryptocurrencies in the background in exchange for giving users additional functions, and an option has been broken to opt out of mining. So far, Apple has not removed the Calendar 2 calendar application, even after Ars Technica informed the company that Calendar 2 has been extracting virtual currency.
The application is supposed to be an improved version of the Apple Calendar application in macOS, but recently, its developer, Qbix, added extra code to Mine Monero, a digital currency launched in April 2014 that was intended to be a more anonymous version of Bitcoin , since you can not see the transactions in a public book. That makes Calendar 2 a rare thing in the app store: there do not seem to be other mining applications in the store, and fewer applications that use mining as a way to get additional value from non-paying users.
The miner runs in exchange for allowing users to access more premium features. Users can choose to drop premium features or pay for them through the App Store.
However, as noted by Ars, the application had an error that kept the miner running, even if users tried to opt out, and a second error that caused the miner to consume more resources than originally planned. A user noticed on Twitter that the application "ate 200% of CPU until I found it and killed it". I did not expect a mine infection from an app store vendor. Wow "The current rating of the application is two out of five in the App Store, with many recent reviews landing stars due to unwanted mining." Qbix said he was in the midst of publishing a solution to the errors.
Mining programs tend to favor Monero instead of Bitcoin or Ethereum, since Monero has a more user-friendly hashing algorithm for the CPU. The Salon website asks readers if they would like to let the media extract the monero through the unused computing power of the readers, as an alternative to looking at ads. In addition, Monero has also become an easy target for a series of malicious mining programs that have emerged in recent months, according to a Symantec report in December.
While Apple does not have any rules that expressly prohibit mining applications, it would not be surprising if the company eliminated those applications, given this phrase in the guidelines: "Applications should not drain the battery quickly, generate excessive heat or exert unnecessary tension" . in the device's resources.
