OVHcloud disclosed a software supply-chain attack on its command-line interface (CLI) repository after an attacker compromised a developer’s GitHub account and distributed malicious binaries designed to retrieve sensitive information from users’ disks. The incident was confirmed by CEO Octave Klaba on October 19, 2026. The malicious releases were identified at 14:47 and blocked by 16:21, resulting in a reported 94-minute exposure window. Users who downloaded affected versions have been advised to remove or update the CLI and rotate potentially exposed credentials. The attacker reportedly gained access to an OVHcloud developer’s GitHub account and used it to introduce a malicious binary into the CLI repository. The utility is used to manage OVHcloud services, making it a potentially valuable target for attackers seeking cloud credentials, access tokens, configuration secrets, and other sensitive information stored locally. The compromised releases were identified as versions v0.11.0, v0.12.0, v0.13.0, v0.14.0, and v0.15.0. According to the disclosure, v0.10.0 was unaffected, and the upcoming v0.16.0 release was not compromised. OVHcloud initially found no evidence of other affected repositories but continued investigating the developer-account compromise, targeted files, and possible data exfiltration. A customer report raised concerns about suspicious account activity and modified release assets, helping uncover the incident. Although the malicious binary reportedly performed its intended secret-retrieval function, the company had not confirmed how many customers were affected or whether credentials were successfully exfiltrated. The incident demonstrates how compromised maintainer accounts and altered release artifacts can undermine trust in legitimate software distribution channels.
