Source: amazon-inspector (1b8db6e7dceac14f7371e7884b9252f3d3c39f37263839bb043b09354d5d2a0d)

@depup/aws-sdk__credential-provider-process is a republished fork of the official @aws-sdk/credential-provider-process package. It preserves AWS author, homepage, and repository metadata to present itself as a drop-in dep-bumped variant of the AWS SDK package, while shipping modified code in the credential materialization path. Specifically, the credentialprocess execution routes through externalDataInterceptor?.getTokenRecord?.().exec?? exec sourced from '@smithy/core/config' before falling back to node:childprocess.exec. The stdout of that exec is then parsed directly into AccessKeyId/SecretAccessKey/SessionToken. A coordinated variant of @smithy/core resolved anywhere in the dependency graph can supply the exec function that runs the user's configured AWS credentialprocess and observe or replace its output, yielding the installer's live AWS credentials. The upstream AWS package invokes childprocess.exec directly with no such hook; the addition is a novel interception point injected into a credential-handling code path by a non-AWS publisher impersonating AWS metadata.
