Red Hat Cloud Services npm Trusted-Publishing Compromise

Suspected

Discovered Jun 2, 2026

Multiple @redhat-cloud-services npm packages were compromised on 2026-06-01 through trusted-publishing abuse tied to the Mini Shai-Hulud Miasma wave. The malicious releases added install-time payload execution, credential collection, destructive fallback behavior, and GitHub workflow tampering risk.

Analysis

Executive Summary

On 2026-06-01, researchers reported a new Mini Shai-Hulud child event affecting the @redhat-cloud-services npm scope. StepSecurity identified 31 malicious package versions across 29 packages, published through trusted publishing after an attacker compromised the RedHatInsights/javascript-clients GitHub workflow path and abused OIDC-based npm publishing [stepsecurity.io opens in a new tab].

This is not a normal vulnerable dependency advisory. It is a supply-chain publish compromise against Red Hat Cloud Services client packages that can execute during npm install. The reported payload is called Miasma, also tracked as The Spreading Blight, and it overlaps the same Mini Shai-Hulud operational pattern of CI/CD compromise, credential theft, GitHub workflow tampering, and destructive pressure after token invalidation [stepsecurity.io opens in a new tab] [ox.security opens in a new tab].

Organizations should search for affected @redhat-cloud-services/* packages in source repositories, lockfiles, package caches, build logs, CI artifacts, and container layers. Any confirmed install on a developer workstation or runner with GitHub, npm, cloud, or deployment credentials should trigger credential rotation from a clean environment.

Impact Determination

Analysis table
Classification	Criteria	Required evidence	Handling decision	Closure condition
Confirmed compromise	An affected package/version was installed or executed and endpoint, process, network, or GitHub audit telemetry shows Miasma selectors or credential collection behavior.	Lockfile/cache hit plus package install logs, process telemetry, shell history, endpoint telemetry, proxy logs, or GitHub audit activity.	Isolate the host or runner, preserve package artifacts, rotate reachable credentials, and audit follow-on GitHub/npm/cloud activity.	Affected packages are removed, credentials are rotated, and downstream audits show no unexplained write activity.
Presumed exposed	An affected package/version was installed on a developer workstation, CI runner, image build, or release environment but runtime telemetry is incomplete.	Dependency lock, package cache, build log, container layer, or npm install record.	Treat GitHub, npm, cloud, registry, and deployment credentials reachable from that environment as exposed.	Risk owners confirm clean rebuilds and credential rotation or accept residual risk.
Potentially exposed	Repositories or builds use `@redhat-cloud-services/*`, but exact resolved versions or install execution is not established.	Repository manifests, lockfiles, private registry logs, CI logs, and package-cache inventory.	Reconstruct package resolution and install execution before narrowing scope.	Each hit is dispositioned as confirmed compromise, presumed exposed, or not exposed.
Not exposed	No affected package names, affected versions, package-cache artifacts, tarballs, or runtime selectors appear in complete evidence.	Negative search across repos, CI logs, package caches, endpoint telemetry, proxy logs, and registry mirrors.	Preserve negative evidence and keep lifecycle-script controls in place.	Evidence coverage includes developer endpoints, CI runners, production builds, and internal mirrors.
Unknown	Dependency inventory, package-cache data, runner telemetry, endpoint telemetry, or audit logs are unavailable.	Named gap with system owner and retention window.	Keep credentials in scope until evidence is recovered or rotation closes the gap.	Missing evidence is recovered or the risk owner accepts residual uncertainty.

2026-06-02: This Halting Problems refresh found no existing local post for the @redhat-cloud-services Miasma wave and created this child event report.

Technical Analysis

The material supply-chain failure is not the mere existence of vulnerable package code. It is the use of trusted CI/CD publishing to push malicious package versions into the public npm registry. StepSecurity reports that the attacker opened a pull request in RedHatInsights/javascript-clients, got workflow-controlled publishing execution, and used the resulting OIDC trusted-publishing path to publish malicious versions [stepsecurity.io opens in a new tab].

The payload belongs in the same response family as Mini Shai-Hulud because the defensive questions are the same: which package versions resolved, which install hooks executed, which credentials were reachable, and what GitHub/npm/cloud activity followed. OX and Mend both describe the payload as a new wave using Miasma or The Spreading Blight naming, with destructive and credential-theft behavior [ox.security opens in a new tab] [mend.io opens in a new tab].

Treat successful installation on a runner as credential exposure unless telemetry proves the lifecycle script did not run. Lockfile-only evidence is not enough for confirmed compromise, but it is enough to keep the environment in scope until package-cache and install-log evidence is collected. [1]

Indicators of Compromise

The following indicators of compromise (IOCs) can be used to scope exposure across local repositories, systems, and telemetry exports:

Domains

registry[.]npmjs[.]org
api[.]github[.]com
github[.]com

Urls

Downstream Abuse Audits

Compromised workstations expose active API credentials, requiring immediate rotated revocation. The following platforms are at risk:

GitHub OIDC and PATs: Attackers harvested SSH private keys and Git Personal Access Tokens. Auditors must inspect recent action runs and release logs during the exposure window.
Cloud IAM Credentials: AWS, Azure, and GCP session tokens. CloudTrail and Activity Logs should be queried for AssumeRole or write operations originating from unexpected IP addresses.
NPM and Package Registries: Publishing tokens and credentials. Registry profiles must be audited for unauthorized version publishes or token additions.

Remediation and Closure

Remove affected packages from lockfiles, purge package-manager caches, rebuild containers from clean dependency state, and block affected package/version pairs in private registry policy. For environments that installed the malicious versions, rotate credentials from a clean host before reconnecting the original asset.

Closure requires negative evidence across repositories, package caches, build logs, CI runner artifacts, endpoint telemetry, and internal npm mirrors. If telemetry is unavailable, close the gap with broad credential rotation and a documented residual-risk decision.
