Attackers regularly target online gaming accounts as they can quickly sell any transferable items along with account logins to a third party. This scenario has cropped up for years now, and has affected a growing number of popular online games ranging from Runescape to Fortnite.
These games run on their own clients — so stealing logins will only give the attacker access to that specific game (sometimes a few others). To gain broader access, attackers are choosing to target digital distribution clients like Steam or Origin.
