After Calendar 2, a popular scheduling app in the Mac App Store, was updated with the ability to mine the Monero cryptocurrency on users’ devices for the developer’s benefit, it quickly disappeared — but why?
Gone, but Not Forgotten
Recently, an update to the Calendar 2 app afforded developer Qbix the ability to mine Monero — a popular, privacy-centric cryptocurrency — with users’ computing power. The mining function only kicked in, however, if users chose to forgo the $18 full-app purchase or $1 monthly subscription fee, both of which granted access to the app’s full functionality.
Now, that app is nowhere to be found, and the reason for its removal is still unconfirmed.
Qbix founder Gregory Magarshak claims the app was pulled from the store in order to remove the bug-infested mining functionality.
Flaws in the software caused the mining program to run indefinitely, as well as use significantly more than the planned 10-20 percent of a Mac’s computing power.
@SGgrc @QbixApps Calendar 2 for Mac (from the App Store) launched a cryptocurrency miner without my permission. Then it ate 200% CPU until I found it and killed it. I didn’t expect a miner infection from an App Store vendor. Wow. It runs the xmr-stak Monero miner.
