"keylogger" may not be the right term here? I'm not familiar with how that term is broadly used for, but my definition of that term is a tool that logs your keypresses. Here, it seems like it was scraping your chrome/firefox data for login cookies?

Honestly there's quite a lot of malware that go against those files, I wonder if there's a way to require high privilege to accessing chrome/firefox appdata, or just block it entirely from other apps.

Yeah you're right, people miss use the term keylogger frequently. These kind of malware are broadly called "stealers" and usually do not involve keylogging.

Actual keyloggers tend to be rare nowadays due to them being easier to detect and the fact that in general the browser data is a more valuable target.
