4chan's systems are believed to have been breached through the exploitation of a old version of PHP.
A cyber-attack has taken down the online forum 4chan.
According to BleepingComputer, members of the Soyjak.party imageboard, or The Party, claimed responsibility. Infiltration of 4chan allowed the compromise of the emails belonging to the forum's administrators and moderators, with The Party's "Chud" posting screenshots indicating access to 4chan's staff admin panels and maintenance tools.
The PHP source code for 4chan was also exposed on the Kiwi Farms online forum. Although details regarding the incident were not provided, 4chan's systems are believed to have been breached through the exploitation of a nearly decade-old PHP version.
Such an attack against 4chan comes after the forum was used to expose data purportedly exfiltrated from Disney, Microsoft, Intel, Twitch, Valve, and other high-profile organisations.
