Overview
sicoob.sdk is a malicious package. This package contains malicious code, and its content was removed from the official package manager. While this package might be attempting to impersonate a valid organization, there is no connection between that organization and this package. To maximize the impact, the attack specifically targets development environments and automated pipelines, aiming to silently harvest high-value credentials that could grant unauthorized administrative access to critical downstream production systems and sensitive data repositories.
