OpenSSF/OSV malware advisory MAL-2026-6459 identifies this version as malicious and supplies the Firewall block.

OpenSSF/OSV advisory MAL-2026-6459 confirms this npm version as malicious. package.json declares a postinstall lifecycle script that automatically runs on npm install and executes roughly 25 curl POST requests harvesting cloud-instance identity and credential data from /data/\* paths (ami-id, instance-id, iam/, identity-credentials/, public-keys/, security-groups, mac, hostname, local/public ipv4, etc.). Each value is sent over plain HTTP to...

## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

package.json declares a postinstall lifecycle script that automatically runs on npm install and executes roughly 25 curl POST requests harvesting cloud-instance identity and credential data from /data/\* paths (ami-id, instance-id, iam/, identity-credentials/, public-keys/, security-groups, mac, hostname, local/public ipv4, etc.). Each value is sent over plain HTTP to http://3dhd6wwmusbh04m22igmzvb4hvnmblza.oastify.com/, a Burp Suite Collaborator out-of-band exfiltration host controlled by the attacker. The package advertises itself as 'a collection of handy string utility functions' but ships no string-utility code coupled to the install hook — only the exfiltration payload. Author, repository, bugs, and homepage fields are all empty strings, consistent with a disposable namespace-squat used to deliver an exfiltration payload (dependency-confusion / typosquat shape). Installing this package on any host — and especially on a cloud build agent — leaks IAM metadata, SSH public keys, and instance identity to an attacker-controlled collaborator endpoint.
