The popular imageboard 4chan is experiencing significant downtime amidst claims of a security breach. A user from the rival Soyjak forum has allegedly accessed and leaked 4chan's source code, known as Yotsuba. Investigations are currently underway.

Current Status and Initial Reactions

4chan has been partially offline for over eight hours, with users reporting broken images and non-functional links. The disruption began early on April 15th, sparking widespread speculation across social media and competing platforms.

Initially, some users suspected server problems or a DDoS attack. However, a more severe claim emerged when a Soyjak.st user asserted they had obtained admin credentials and leaked 4chan's internal codebase.

Details of the Alleged Leak

Links to what are purportedly segments of the Yotsuba source code have surfaced on various platforms, including GitHub Gists and private paste sites. Preliminary reviews suggest these samples align with 4chan's backend structure.

  • The leaked files reportedly contain core PHP scripts and administrative tools.
  • Some files use outdated coding practices, raising security concerns.
  • Security risks include the use of extract() on user-submitted data, a practice that can introduce vulnerabilities if not properly sanitized.

Despite not storing typical sensitive user data, the exposure of 4chan's codebase could allow attackers to exploit server-level vulnerabilities and gain insights into internal operations.

Soyjak.st's Alleged Involvement

Soyjak.st, a smaller imageboard focused on parody and memes, has a contentious relationship with 4chan. Whether the attacker is genuinely linked to Soyjak.st or merely using its name remains uncertain, as no official attribution has been confirmed.

If verified, this breach could mark a significant incident where one imageboard community compromises another's infrastructure.

4chan's Silence and User Caution

As of now, 4chan has not issued any official statement regarding the outage or the alleged breach. While the site's homepage is accessible globally, many boards remain unstable.

Without confirmation from 4chan, it's unclear if the administrators are aware of the breach or are actively addressing it. Users should exercise caution with any files or links claiming to originate from 4chan, as these could be phishing attempts or fake.
