The popular Swedish online forum Flashback suffered a significant distributed denial-of-service (DDoS) attack that rendered the site inaccessible for much of the weekend. The overload attack originated from multiple sources and was notably large compared to typical incidents targeting the forum. Flashback's internet service provider, Bahnhof, confirmed the extensive nature of the assault.

Jon Karlung, CEO of Bahnhof, highlighted the unusual scale of the attack, noting that such large cyberattacks are rare and generally carried out by a limited number of sophisticated entities capable of coordinating such efforts. While the attack has caused considerable disruption, Karlung resisted speculating on who might be behind it, emphasizing that further analysis is necessary.

Flashback, known for hosting open discussions on a range of topics, has previously been targeted but seldom with an assault of this magnitude. The outage affected users' ability to access the site throughout the weekend, underscoring concerns about the vulnerability of online platforms to coordinated cyberattacks. The incident draws attention to cybersecurity challenges faced by significant Swedish web communities, particularly those hosting controversial or high-profile discussions.
