Steam
Steam has faced DDoS attacks a couple of times, though I haven't heard it fully compromised. Players usually are responsible, as games are tied to accounts. When you purchase a game, you receive an email receipt proving ownership. If any part is missing, reach out to Steam support and wait a few months for resolution.
Steam's security measures are quite strong, and it seems they haven't been completely compromised. Usually, issues arise when people share their login details publicly.
Steam’s security measures would make it very difficult to breach an account without the correct credentials. The system seems designed to protect against unauthorized access, and there are no reports of a full breach. It might just be a minor technical issue.
