Alarming reports have emerged claiming that hackers are offering data from approximately 89 million Steam user accounts for sale. The listing appeared on dark web platforms and reportedly carries a price tag of $5000 for the full dataset.

Early theories suggested that the breach originated within Valve’s own infrastructure. However, updated information points to a different scenario — one involving a compromise through a third-party vendor linked to Steam. This method aligns with known supply chain attacks, where threat actors exploit external services with weaker cybersecurity.

While Valve has not officially confirmed the incident, sources indicate that the company is actively investigating the matter internally. They also stress that there's no clear evidence of a direct breach involving core systems or authentication providers like Twilio.

Until Valve releases an official statement, it’s recommended that all users take precautionary steps: reset passwords, review account activity, and enable two-factor authentication. Even if the breach didn't stem from Valve itself, the scale of the potential exposure is significant and warrants immediate user attention.
