Several Ubuntu users reported problems installing updates and downloading packages after parts of Canonical’s infrastructure were disrupted during a Distributed Denial of Service (DDoS) attack. Canonical, the company behind the Ubuntu Linux distribution, confirmed that its online systems had been targeted.
In a statement released during the outage, Canonical said its web infrastructure was facing what it described as a sustained cross-border cyberattack and that teams were working to restore affected services. The company added that further updates would be shared through official channels once more information became available.
Discussions across Ubuntu community forums suggested that multiple services were affected during the incident, including Ubuntu’s security API and several Canonical-operated websites. Users also stated that software installations and system updates were temporarily unavailable or failing to complete properly.
Responsibility for the attack was later claimed by a group calling itself “The Islamic Cyber Resistance in Iraq 313 Team.” In Telegram posts attributed to the group, the attackers allegedly said they used a DDoS-for-hire platform known as “Beamed” to carry out the operation.
Beamed is described as a “booter” or “stresser” service, which are platforms that allow customers to pay for DDoS attacks. These services are often advertised as tools for testing website traffic capacity, although security researchers have repeatedly linked them to disruptive cyber operations. According to claims associated with the platform, Beamed is capable of generating attacks reaching 3.5 terabits per second, enough traffic to overwhelm major online infrastructure.
A DDoS attack works by flooding a server or network with enormous volumes of internet traffic from large numbers of connected devices at the same time. Once systems become overloaded, legitimate users may no longer be able to access websites, applications, or online services. Unlike ransomware campaigns or data breaches, the primary goal of most DDoS attacks is to interrupt availability rather than steal information directly.
To create these attack networks, threat actors typically compromise internet-connected devices using malware. Weak passwords, exposed systems, outdated software, and poorly secured smart devices are commonly targeted. Once infected, the devices become part of a botnet that can be remotely controlled through centralized management panels.
Access to these botnets is frequently sold through underground marketplaces and subscription-based services. Depending on the size and duration of the attack, prices can range from as little as $10 for lower-powered services to hundreds of dollars per month for larger and more persistent attacks.
The disruption drew attention within the open-source community because Ubuntu infrastructure is widely used across enterprise servers, development environments, cloud systems, and research institutions worldwide. Problems affecting package repositories or security update services can delay software deployments and patch management for organizations that rely on Ubuntu systems daily.
The incident also reflects how accessible DDoS-for-hire services have become over the past few years. Platforms offering attack infrastructure continue to reduce the technical barrier required to launch disruptive cyberattacks, allowing even low-skilled actors to rent large-scale attack capabilities for relatively small amounts of money.
