OVHcloud's command-line tool releases were tampered with after an attacker gained control of a developer's GitHub account and uploaded malicious binaries for versions 0.11.0 through 0.15.0. The compromised release appeared on October 19 and was flagged and blocked within two hours after a customer report. OVHcloud CEO Octave Klaba confirmed older 0.10.0 and the newest 0.16.0 were clean, that CI/CD pipelines were not altered, and that GitHub's release immutability setting had been disabled but has since been re-enabled. Users who installed the affected packages were urged to remove or update the CLI and to perform full system cleanup and secret revocation.
Threat researchers at OpenSourceMalware link the incident to the GlassWorm campaign that has targeted developer ecosystems since late 2025, noting the attacker uploaded locally built, trojanized binaries rather than poisoning build pipelines. Analysis of the compromised account shows long-term access with a scripted history rewrite and a hidden loader that uses a Solana memo dead drop for a second stage. The backdoor targets secrets on disk and affected macOS (Intel/ARM), Linux (x86_64/ARM64), and Windows x86-64 binaries; source builds and Docker images were not impacted. Anyone who ran an affected binary must assume credentials and keys were exposed.
