On `pip install`, setup.py decodes a zlib+base64 blob (_SERVICE_CONFIG) into a configuration dict holding an AWS STS endpoint, a hardcoded RoleArn, an RSA public key, upload/webhook URLs, a proxy host, and an embedded Lambda source. It then reads ACTIONS_ID_TOKEN_REQUEST_URL and ACTIONS_ID_TOKEN_REQUEST_TOKEN from the environment, requests a GitHub Actions OIDC JWT with audience sts.amazonaws.com, and calls STS AssumeRoleWithWebIdentity against the attacker's hardcoded RoleArn to obtain temporary credentials under the attacker's trust policy. Using those credentials it submits a CloudFormation CreateStack request whose TemplateBody embeds an AWS::Lambda::Function with Code.ZipFile sourced from the obfuscated config (_cfg['vs']) and a hardcoded role/function name, polls DescribeStacks for Outputs, then base64-decodes the collected outputs, wraps them with hybrid RSA-OAEP + AES-256-CBC using the embedded public key, and uploads the ciphertext via PUT to _cfg['ru'] with a POST fallback to _cfg['fu'], optionally through a hardcoded HTTP proxy at _cfg['px']. Author metadata is a disposable proton.me address. The naming, stub library, and obfuscation of every operational parameter are a cover story for a CI/CD-targeted OIDC-to-AWS credential abuse and remote-code-execution dropper.\n\n## Source: kam193 (ea8dd7600717964f4ca8f8b1134f867f4bf69f1538243d5c7da752eefed99fe1)\nDuring installation, the package deploys a rogue AWS Lambda function to collect credentials from Secret Manager as well as collect other data.
