This supply chain attack potentially affects thousands of users who may have updated to the malicious versions. The compromised packages could contain malicious code injected by an unknown threat actor. Users are advised to avoid updating to these versions and investigate their systems for potential compromise. The initial report came from a Reddit post and links to a blog post for further details.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003cp\u003eWhile the specifics of the attack chain are not fully detailed in the source, a typical supply chain attack targeting PyPI packages involves the following steps:\u003c/p\u003e\n\u003col\u003e\n\u003cli\u003e\u003cstrong\u003ePackage Compromise:\u003c/strong\u003e Threat actor gains unauthorized access to the Litellm PyPI account or the build environment.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eMalicious Code Injection:\u003c/strong\u003e The attacker injects malicious code into the setup.py or other relevant files within the Litellm package.
