Steam Data Breach Scare: Valve and Twilio Respond to Leak Reports
A recent scare involving a potential Steam data breach sent ripples of concern through the gaming community. Reports surfaced alleging that a massive trove of user data, potentially affecting over 89 million accounts, was being offered for sale on the dark web. However, Valve, the company behind Steam, has swiftly responded to these claims, assuring users that their core account information remains secure.
The initial reports, amplified by social media and cybersecurity circles, suggested that a threat actor was offering a dataset containing user records, linked to real-time two-factor authentication (2FA) SMS logs for $5,000. The claim triggered immediate concern given Steam's global reach and the sensitivity of user data.
Valve quickly launched an investigation. Their findings indicate that while older text messages containing one-time codes had been leaked, these messages did not compromise Steam's systems directly. "We have examined the leak sample and have determined this was not a breach of Steam systems," Valve stated. They further emphasized that users do not need to change their passwords or phone numbers as a result of this event, as the leaked data did not associate the phone numbers with Steam accounts, password information, payment information, or other personal data.
Adding another layer to the story, Twilio, a cloud communications company that provides SMS and 2FA services, was also implicated. Independent games journalist MellowOnline1 suggested the incident might be a supply-chain compromise impacting Twilio. The theory proposed a compromised admin account or abused API keys within Twilio's backend systems. However, Twilio has also denied they were breached.
"There is no evidence to suggest that Twilio was breached. We have reviewed a sampling of the data found online, and see no indication that this data was obtained from Twilio," a Twilio spokesperson told BleepingComputer.
While the exact source of the leaked data remains under investigation, a plausible explanation points to a potential leak from an SMS provider mediating communication of one-time access codes between Twilio and Steam users. BleepingComputer reported finding historic SMS text messages with one-time passcodes for Steam, including the recipient's phone number, suggesting the information's origin predates the recent scare. It's worth noting that though they found delivery dates related from the beginning of March.
Despite the assurances from both Valve and Twilio, the incident serves as a vital reminder of the ever-present need for robust online security practices. Valve recommends setting up the Steam Mobile Authenticator for enhanced account security and advises users to remain vigilant against unsolicited security messages.
This incident underscores the complexities of data security in interconnected systems, highlighting the importance of supplier security and layered defenses. While the immediate threat seems to have subsided, the underlying vulnerabilities require continuous monitoring and improvement.
