Cybersecurity researchers have found malicious “imageless” containers in Docker Hub, creating a potential for supply chain attacks. The containers house documentation that leads users to phishing or malware websites. Over 4 million such repositories have been identified, used to redirect users to fraudulent sites in three distinct campaigns. This underscores the need for caution when accessing open-source registries.
From the meeting notes:
– Cybersecurity researchers have discovered multiple campaigns targeting Docker Hub by planting millions of malicious “imageless” containers over the past five years.
– Over four million of the repositories in Docker Hub are imageless and have no content except for the repository documentation, which could lead to phishing or malware-hosting websites.
– 3.2 million of the imageless Docker Hub repositories have been used to redirect users to fraudulent sites as part of three broad campaigns: Downloader, E-book phishing, and Website.
– The payload delivered as part of the downloader campaign is designed to contact a command-and-control server and transmit system metadata.
– The exact goal of the website cluster campaign is currently unclear, but it is concerning due to lax content moderation policies.
– Developers are urged to exercise caution when downloading packages from open-source ecosystems.
