Security Incidents and Community Progress: This Week in Linux
Ubuntu Under Fire: DDoS and Compromised Social Media
This week brought a series of challenges for the Ubuntu ecosystem. A distributed denial-of-service (DDoS) attack targeted Canonical's infrastructure for nearly a week, flooding servers with traffic and causing widespread outages. The ubuntu.com website, Snap Store, Launchpad, and other key services became unavailable or unreliable. Users experienced difficulties running snap install commands or pulling packages from PPAs during this period—a direct consequence of the attack.
The trouble didn't stop there. Shortly after, the official Ubuntu Twitter account was compromised and used to promote a cryptocurrency scam. This incident added to the mounting concerns for the community, though Canonical has since taken steps to regain control.
New Linux Vulnerability: 'Copy Fail' Exploit
Another security issue emerged this week: a local privilege escalation vulnerability dubbed Copy Fail. This exploit allows an attacker with local access to elevate their privileges, but it poses little risk to typical desktop users. The key mitigation is to keep your system updated, as kernel patches will address the flaw. For more details, see this analysis.
Positive Developments in Open Source Infrastructure
Amid the negative headlines, there were encouraging stories. The Dutch government is building its own code hosting platform based on Forgejo. The soft launch already includes four ministries, several municipalities, and the Electoral Council's vote-counting software—a strong vote of confidence in open source self-hosting.
Additionally, Germany's Sovereign Tech Agency launched a paid pilot program aimed at enabling independent maintainers of web standards to participate in working groups (IETF, W3C, ISO). Traditionally, the cost of attending these meetings has excluded many small developers; this program aims to change that.
Microsoft in the Spotlight: Copilot Controversy and DOS Open Sourcing
Microsoft faced scrutiny this week when it was discovered that VS Code was incorrectly crediting GitHub Copilot for commits written entirely by humans—even on machines where Copilot had been explicitly disabled. The cause was traced to a single pull request that changed a default setting without a release note or user notification.
On a brighter note, on the 45th birthday of MS-DOS, Microsoft open-sourced the original code under an MIT license. While this move won't change the computing landscape, it's a significant gesture for computing history. Microsoft originally purchased DOS for under $100,000, a decision that ultimately generated billions in revenue.
Other Notable Linux News

- Terminal-based file manager: An impressive new terminal file manager has been released, offering a powerful alternative to GUI file browsers.
- Linux Mint HWE ISOs: New hardware enablement (HWE) ISOs for Linux Mint are now available, ensuring smoother support for newer hardware.
- Paid program for standards development: As mentioned, the Sovereign Tech Agency program aims to fund participation in web standards groups.
Community and Release Updates
The Ubuntu flavour list shrank with the release of 26.04, a move that commentator Rolan argues is a necessary correction to focus resources on sustainable releases. Meanwhile, Linux Mint extended its release cycle to December 2026, which should provide stability for existing users while the team focuses on long-term development.

Copy Fail Vulnerability Analysis
The Copy Fail exploit (CVE pending) is a local privilege escalation that takes advantage of a race condition in the Linux kernel's copy-on-write mechanism. Desktop users are not at risk from remote attacks, but system administrators should prioritize patching. Updates are already rolling out across major distributions.
