The hackers responsible for a ransomware attack on Cyberpunk 2077 developer CD Projekt appear to have started sharing the information they stole from the company.

What looks like the source code for CD Projekt's Gwent, a card game set in the universe of The Witcher series, cropped up online Wednesday. Vice's Motherboard verified the data, which it says includes Gwent assets and multiple versions of the game itself. Testramework files, which game developers use to test applications, also appear in the download.

A note in the download indicates the next leak will take place tomorrow, likely referring to Thursday.

Twitter user vx-underground posted a screenshot of the download in question Wednesday. In a following tweet, the user said the source code for The Witcher 3, Cyberpunk 2077 and more is being auctioned on hacker forum EXPLOIT with an opening bid of $1 million, or for an immediate purchase of $7 million. (Vx-underground and others initially misunderstood that first bid as $1,000.)

CD Projekt told Motherboard it was "still actively investigating this incident and have no further comments to provide at this time," in response to questions about Wednesday's developments. The company revealed the attack had taken place Tuesday, saying it would not cooperate or negotiate with the hackers.

"We are taking necessary steps to mitigate the consequences of such a release, in particular by approaching any parties that may be affected due to the breach," the company said in its statement acknowledging the attack.
