A calendar app ter the Mac App Store has bot mining cryptocurrency te the background ter exchange for providing users extra features — and an option to opt out of mining has bot violated. So far, Apple has not taken the scheduling app Calendar Two down, even after Ars Technica informed the company that Calendar Two has bot mining virtual currency.
The app is supposed to be a buffed-up version of Apple’s Calendar app ter macOS, but recently, its developer, Qbix, added reserve code to mine monero, a digital coin launched ter April 2014 and meant to be a more anonymous version of bitcoin, spil you can’t view transactions on a public ledger. That makes Calendar Two something of a rarity te the App Store — there don’t show up to be other mining apps ter the store, let alone apps that use mining spil a way to get extra value from non-paying users.
The miner runs te exchange for letting the users access more premium features. Users can opt out by keeping premium features off or paying for them through the App Store.
However, spil Ars noted, the app had a bug that kept the miner running, even if users attempted to opt out, and a 2nd bug that caused the miner to consume more resources than originally intended. A user noted on Twitter that the app “ate 200% CPU until I found it and killed it. I didn’t expect a miner infection from an App Store vendor. Wow.” The app’s current rating is two out of five ter the App Store, with many latest reviews docking starlets because of the unwanted mining. Qbix stated that it wasgoed ter the middle of publishing a fix for the bugs.
Mining programs tend to favor Monero overheen Bitcoin or Ethereum, spil Monero has a more CPU-friendly hashing algorithm. Salon’s webstek asks readers if they would like to let the media outlet mine monero through readers’ unused computing power, spil an alternative to looking at ads. Additionally, Monero has also become an effortless target for a spate of malicious mining programs that have emerged ter latest months, according to a report from Symantec ter December.
While Apple doesn’t have any rules expressly banning mining apps, it wouldn’t be surprising for the company to eliminate such apps, given this sentence te the guidelines: “Apps should not rapidly drain battery, generate excessive fever, or waterput unnecessary strain on device resources.” We’ve reached out to Apple for comment.
Update March 13th, 8:35AM ET: Calendar Two has bot pulled from the Mac App Store since the time of publication. It’s not clear if this wasgoed done by its developer, Qbix, or by Apple. After publication, Qbix said it would liquidate the miner from its app.
