Malicious code in @hrmony/pladddform-testing (npm)

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (607004ff93f1fcd5fbf7b1cf6b5e104b7f26eb699aee3dd4f8bbb33494f0b096) On module import, index.js executes an unconditional exfiltration payload against the installer/runtime host. It queries the AWS EC2 Instance Metadata Service at http://169.254.169.254 using IMDSv2 to enumerate the instance identity document, user-data, IAM role names, and the per-role temporary security credentials. It also enumerates every entry of process.env and recursively reads all files under /var/run/secrets/ (the standard Kubernetes service-account and secret mount). The combined data is POSTed to the hardcoded attacker endpoint https://hrnmn.dd.h4x.tv/save_instance_info_from_pkge_hrmony_pladddform-testing, and a separate top-level fetch to the same host beacons successful execution. The package ships no legitimate functionality: its only substantive file is the exfil script, the description is empty, and the name (@hrmony/pladddform-testing) plus the exfil URL path segment (pkge_hrmony_pladddform-testing) match a typosquat/dependency-confusion shape targeting an internal or similarly named scope. ## Source: ghsa-malware (c92cc1e06fa8e7384e23ef90c47289ac2ca625479ac19014ed81fff94ff980bd) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
