Twitch security breach had minimal impact, the company states

Twitch provided an update for the recent security breach, the company confirmed that it only had a limited impact on a small number of users.

Twitch downplayed the recent security breach in an update, the company said it only impacted a small number of users.

According to the update, login credentials or full payment card data belonging to users or streamers were not exposed.

The root cause of the incident was a server configuration change that allowed improper access by an unauthorized third party. Twitch passwords have not been exposed, the company believes that systems that store Twitch login credentials, which are hashed with bcrypt, were not accessed.

“Twitch passwords have not been exposed. We are also confident that systems that store Twitch login credentials, which are hashed with bcrypt, were not accessed, nor were full credit card numbers or ACH / bank information.” reads the update. “The exposed data primarily contained documents from Twitch’s source code repository, as well as a subset of creator payout data. We’ve undergone a thorough review of the information included in the files exposed and are confident that it only affected a small fraction of users and the customer impact is minimal. We are contacting those who have been impacted directly.”

Early this month, an anonymous 4chan user has published a torrent link to a 128GB file on the 4chan discussion board, the leaked archive contains sensitive data stolen from 6,000 internal Twitch Git repositories. The leaker, who used the #DoBetterTwitch hashtag, claims to have leaked the data in response to harassment raids targeting the platform streamers this summer.In August, the streamers used the same hashtag to share on Twitter evidence of the hate raids that targeted them, at the time the platform chats were flooded with hateful content.

“Their community is also a disgusting toxic cesspool, so to foster more disruption and competition in the online video streaming space, we have completely pwned them, and in part one, are releasing the source code from almost 6,000 internal Git repositories,” reads the message published by the leaker.

The anonymous user’s thread, named ‘twitch leaks part one’ claims that the archive contains:

• The entirety of twitch.tv, with commit history going back to its early beginnings
• Mobile, desktop, and video game console clients
• Various proprietary SDKs and internal AWS services used by platform
• Every other property that Twitch owns, including IGDB and CurseForge
• An unreleased Steam competitor from Amazon Game Studios
• Twitch SOC internal red teaming tools (lol)
• and the creator payout reports from 2019 until now.
