Cybersecurity researchers have recently uncovered a software supply chain attack targeting the Go ecosystem. This attack involves a malicious package that can give threat actors remote access to infected systems. The package in question is a malicious version of the legitimate BoltDB database module, named github.com/boltdb-go/bolt, which was published to GitHub in November 2021. This malicious package was cached indefinitely by the Go Module Mirror service, allowing unsuspecting users to download it.
According to security researcher Kirill Boychenko, once the backdoored package is installed, it grants the threat actor remote access to the compromised system, enabling them to execute arbitrary commands. This attack is significant as it represents one of the earliest instances of a malicious actor abusing the Go Module Mirror’s caching mechanism to distribute malicious code. The attacker even modified the Git tags in the source repository to redirect users to the benign version, making manual audits of the repository ineffective.
The deceptive tactics employed by the attacker ensured that developers using the go CLI continued to download the backdoored package without detecting any malicious content during manual audits of the GitHub repository. The caching mechanism allowed the malicious version of the package to persist even after changes were made to the repository. This highlights the need for developers and security teams to monitor for attacks that exploit cached module versions to evade detection.
This discovery comes in the wake of Cycode detailing three malicious npm packages that contained obfuscated code designed to collect system metadata and execute remote commands on infected hosts. The cybersecurity community is urged to stay vigilant against such supply chain attacks and to follow platforms like Twitter and LinkedIn for more exclusive content on cybersecurity developments. In a landscape where immutable modules offer security benefits and potential abuse vectors, it is crucial to remain proactive in detecting and mitigating such threats.
