Still trying to understand - Did the mod developers intentionally shipped malicious code or they were compromised by some external attacker to target the downstream users?
The author indicates that the mod authors' account was "likely compromised" indicating a bad actor took over their account somehow, perhaps made easier by prolonged inactivity?
I don't think the author of this piece found it useful to speculate though and I have to agree. No need to break out pitch forks - let those involved get to the bottom of it.
