Steam Hack Scare: 89 Million Accounts at Risk or Just a Hoax? Valve Speaks Up!

by

Reports persist about a potential Steam system breach, with Valve confirming the incident in a recent statement. It’s alleged that over 89 million user accounts may have been affected, exposing sensitive information such as text message logs.

A May 10th post on LinkedIn is causing quite a stir within the PC gaming community. The account ‘Underdark AI’ claimed a significant Steam data leak, which allegedly affected nearly 90 million users.

A statement suggested that a post existed on a widely recognized dark web marketplace, where a potentially harmful individual was offering $5,000 for information they had acquired. This supposedly obtained data encompassed mobile phone numbers, text message logs from those phones linked to accounts, and even potential two-factor authentication messages.

Word spreading fast about the claimed data leak, but now Valve has directly tackled the issue, asserting that no such security breach occurred within Steam’s systems.

Valve refutes claims of “massive” Steam hack

Following several days of scrutiny, Valve released their official statement on May 14th, stating unequivocally that the alleged leak did not infiltrate their Steam systems.

You might’ve come across news about older text messages being leaked, which were initially sent to Steam users. Upon investigating the leaked data, we can confirm that it wasn’t a result of any breach in our Steam system.

Despite Steam’s cybersecurity team continuing to investigate the root cause of the breach, they have reassured users that the impact has been limited.

The leaked data, it turns out, was primarily composed of old text messages containing temporary verification codes that expired within 15 minutes and the recipients’ phone numbers.

To clarify, even though mobile numbers were involved, the leaked data didn’t link those numbers to specific Steam accounts, passwords, payment details, or any other personal information.

Essentially, it’s said that hackers don’t have significant capabilities in this instance. Since the threat appears insignificant, Valve has reassured its users that there’s no requirement to modify passwords or phone numbers due to this occurrence.
