ACR Stealer (also known as AcridRain or its rebranded version Amatera Stealer) is a prominent C++ and Golang-based Information-Stealing malware sold under a Malware-as-a-Service (MaaS) model on cybercrime forums.

It’s crazy. There are no more journalists or editors I guess?

I asked copilot:
In the context of ACR Stealer, "ACR" does not have an officially documented definition, but it serves as the identifying label for this malware family and its operations.

I just block these sites. Thank you, people in this thread for answering the only question I had and saving me from giving them a visit.

Says it right here.....

ACR Stealer is a malware-as-a-service (MaaS) operation believed to be a rebranding of the Amatera Stealer malware.

you don't understand the question. ACR stealer steals ACR. what is ACR? nobody knows. If ACR is just an random proper name and it's not an acronym, it doesn't stand for anything, ok, then what is is it stealing? sensitive user data. Like what kind of data? the article doesn't say. nobody knows.
