Twitch data breach updates: login credentials or card numbers not exposed

An anonymous individual has leaked the source code and data of the popular video streaming platform Twitch via a torrent file posted on 4chan.

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 Twitch 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.

The popular video streaming platform confirmed the security breach and is investigating it to determine the extent of the incident.

We can confirm a breach has taken place. Our teams are working with urgency to understand the extent of this. We will update the community as soon as additional information is available. Thank you for bearing with us.

The company confirmed that the data was exposed online due to a misconfiguration of a Twitch server.

Twitch provided today an update about its investigation and announced to have reset all stream keys as a precautionary measure. Users can get their new stream key here: https://dashboard.twitch.tv/settings/stream.

Depending on broadcast software used by the customer, they may need to manually update the software with this new key to start their next stream:

• Twitch Studio, Streamlabs, Xbox, PlayStation and Twitch Mobile App users should not need to take any action for your new key to work.
• OBS users who have connected their Twitch account should also not need to take any action. OBS users that have not connected their Twitch account to OBS will need to manually copy their stream key from their Twitch Dashboard and paste it into OBS.
• For all others, please refer to specific setup instructions for your software of choice.

The company added it is not aware that login credentials have been exposed.

At this time, we have no indication that login credentials and credit card numbers have been exposed.

“As the investigation is ongoing, we are still in the process of understanding the impact in detail. We understand that this situation raises concerns, and we want to address some of those here while our investigation continues.” reads the update published by the company. “At this time, we have no indication that login credentials have been exposed. We are continuing to investigate. Additionally, full credit card numbers are not stored by Twitch, so full credit card numbers were not exposed.”
