Steam account breach: Breaking down the claims and Valve's response

If you're one of the millions using Steam, the world's largest digital gaming platform, this might be the right time to update your password and review your account security.

Reports have surfaced suggesting that 89 million Steam account records may have been compromised and are allegedly being sold on the dark web. The potential breach, if proven true, could mean a serious risk for users, especially those who have not enabled two-factor authentication (2FA) or use weak passwords.

The alarm was first raised on social media by @Mellow_Onlinel, who shared that around two-thirds of all Steam accounts might have been exposed in a massive data leak. According to his posts, the stolen data is being sold on the dark web forum Mipped for just $5 (approximately 111,000 Czech Koruna).

The hacker, using the alias Machine1337, claimed responsibility for the breach. A cybersecurity firm called Underdark confirmed the report through a post on LinkedIn, which stated that the threat actor was offering a dataset of over 89 million user records for $5,000 on a well-known hacking forum.

The hacker's dark web listing reportedly included a Telegram contact, a sample of the stolen data, and even internal vendor information, hinting that the attacker might have gained deeper access to systems connected to Steam.
