A massive Distributed Denial of Service (DDoS) attack, attributed to the sophisticated Aisuru botnet, has caused widespread service outages impacting major gaming platforms like Steam and Riot Games, alongside disruptions to other critical services including AWS and PlayStation Network. This attack reportedly achieved a record-breaking bandwidth of 29.69 terabits per second (Tbps), significantly surpassing previous DDoS records and underscoring the escalating threat posed by advanced cybercrime infrastructure to global digital services and infrastructure for institutional investors.
Multiplayer gamers on different platforms have experienced service outages and disruptions simultaneously. The cybersecurity community suspects a major distributed denial of service attack (DDoS) from Aisuru, a massive botnet pushing out record-breaking traffic. Downdetector users are reporting widespread problems affecting Steam and Riot Games, two of the world’s largest gaming platforms. Gamers complain about being unable to play major titles, such as Counter-Strike, Dota 2, Valorant, League of Legends, and many others. Outage reports began surging around 8:00 PM EDT on October 6th, with thousands of users mentioning losing server connections. The brief disruptions have recurred several times since. Riot Games' status page confirmed critical game disconnection issues, affecting gamers on all major platforms: Windows, macOS, iOS, and Android. “We’re aware of a problem causing players to disconnect from their games and have disabled ranked queues while we investigate,” the alert reads. The disconnection issues prompted the developer to disable ranked games. The issues also seem to be affecting other major platforms, including non-gaming ones. More reports than usual were received about issues affecting PlayStation Network, Epic Games, Hulu, AWS, xfinity, Cox, and other services. The internet is melting: Steam down. Epic Games down. AWS down. Cloudflare wobbling. undefined CHRISPI (@criptolion) October 7, 2025 f you’re refreshing, you’re not alone. pic.twitter.com/Q98TmTqVYj Massive DDoS attack suspected While official confirmations are still pending, many cybersecurity experts attribute the disruptions to a massive DDoS attack, allegedly from Aisuru, which is likely the largest currently operating botnet. “Attackers began a series of sophisticated TCP carpet bomb attacks that aim to replicate legitimate traffic as closely as possible. This is one of the more advanced attack vectors we’ve seen, and we worked quickly to develop a patch and ship it out globally,” one cyber defender’s alert was quoted on Reddit. Cybercrime news reporter vxdb on X reported about the DDoS attack, likely originating from the Aisuru botnet, that had shattered all previous records: the bandwidth reached 29.69 terabits per second (Tbps). The previous record was 22.2 Tbps – a DDoS attack on September 23rd, blocked by Cloudflare, was twice as large as anything seen on the internet before. The Aisuru botnet, first discovered by XLab researchers in August 2024, has been growing ever since and has repeatedly broken records. In May, it attacked KrebsOnSecurity, a cybersecurity blog, with a 6.3 terabit per second data rate. This September, the attacks peaked at 11.5Tbps. According to XLab, this mega botnet spreads by compromising vulnerable internet-connected devices, such as A-MTK cameras, D-Link, Linksys, and other routers, gateways, DVRs, and others. The latest estimates suggest that the botnet controls around 300,000 nodes. The group behind Aisuru seems highly organized. It employs advanced techniques to evade detection and maintain control of the infected systems. The researchers also noted attempts to convey certain ideological content. “The Aisuru botnet has launched attacks worldwide, spanning multiple industries. Its primary targets have been located in regions such as China, the United States, Germany, the United Kingdom, and Hong Kong. The attacks show no strong signs of selectivity, with several hundred targets hit on a daily basis,” XLab warned. This massive cybercrime infrastructure now also seems to be exploited for proxy services. Unlock more exclusive Cybernews content on YouTube. Your email address will not be published. Required fields are markedmarked A massive Distributed Denial of Service (DDoS) attack, attributed to the sophisticated Aisuru botnet, has caused widespread service disruptions across global digital infrastructure. This event, which commenced around 8:00 PM EDT on October 6th, achieved a record-breaking bandwidth of 29.69 terabits per second (Tbps), significantly exceeding the previous record of 22.2 Tbps. The sophisticated "TCP carpet bomb" attack vector targeted major gaming platforms like Steam and Riot Games, alongside critical non-gaming services such as PlayStation Network (SONY), AWS (AMZN), Hulu (DIS), and internet providers like Xfinity (CMCSA). The Aisuru botnet, identified by XLab researchers in August 2024 and currently estimated to control 300,000 compromised IoT nodes, represents a highly organized and advanced cybercrime infrastructure. Its capabilities include evading detection and launching attacks across multiple industries worldwide, with targets in regions like China, the US, Germany, the UK, and Hong Kong. This incident highlights the escalating threat of sophisticated, large-scale cyberattacks to critical digital services and infrastructure. The broad impact, indicated by a "strongly negative" general sentiment (-0.7) and high market impact (0.7), signals significant operational and reputational risks for affected companies. Individual ticker sentiments confirm negative implications for SONY (-0.4), DIS (-0.4), AMZN (-0.5), CMCSA (-0.4), and NET (-0.3), whose services experienced disruptions or wobbled. The recurring nature of these brief outages suggests ongoing vulnerability and the potential for continued operational challenges across the affected digital ecosystem.
