element-guci-util@12.12.1

Package is published as an element-ui utility library (`element-guci-util`, description '元素-ui 常用工具函数集合') but its main entrypoint contains no utility functions. On `require()`/`import`, top-level code invokes `iconFont()` which checks the current date and, on or after 2026-10-01, invokes `iconDont()`. `iconDont` fabricates a synthetic `.exe` Blob and triggers an anchor click to force a download on the end user, opens `https://admin.nikolive.cn/` in a new window, calls `location.reload(true)` on a 500ms interval, and starts CPU/memory exhaustion loops. Package metadata carries placeholder values (`author: '你的名字'`, repo `你的git仓库地址`), and `package.json` declares the package as its own dependency at `^9.9.9` while publishing as 10.0.0 — a self-referential range disjoint from the published version, which alters what subsequent installs resolve to. Any web application bundling this module will ship the payload to its end users once the trigger date passes; the forced.exe download plus redirect to an attacker-controlled host constitutes an attacker-benefiting payload against the installer's downstream users, not benign vandalism. ## Source: ghsa-malware (8649406e7c2820cb97dc67905db9b89efb2984a1083523550842fe581146b9b3) 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.
