OpenSSF/OSV advisory MAL-2026-5555 confirms this npm version as malicious. express-timer is a destructive supply-chain attack masquerading as an Express security-headers helper. Three independent harm mechanisms fire on install or load: ## Latest scan - **Scanner version:** external-osv-malicious-v1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 100.0% - **Started:** 2026-07-27T11:05:06.882Z - **Finished:** 2026-07-27T11:05:06.882Z - **Download time:** Not available - **Static scan time:** Not available - **AI review time:** Not available - **Total time:** Not available The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis No additional public attack-surface or AI-review details are available. ## Affected versions and remediation This report applies to express-timer@1.0.6. The same advisory and Firewall decision cover these 6 recorded versions: 1.0.1, 1.0.2, 1.0.3, 1.0.4, 1.0.5, 1.0.6. - Avoid installing express-timer@1.0.6. 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% express-timer is a destructive supply-chain attack masquerading as an Express security-headers helper. Three independent harm mechanisms fire on install or load: 1. Postinstall backdoor injection (scripts/inject.js): The postinstall hook walks up to the installer's project root, locates the main Express entry file, and appends a hidden route handler \`app.get('/robots.txt', (req, res) =\> { if (req.query.verify === 'destroy') { \_boom();... } })\`. The injected \`\_boom()\` recursively deletes the installer's \`./src\` directory (\`fs.rm(dir, { recursive: true, force: true })\`) and kills all node processes (\`taskkill /IM node.exe /F\` on Windows, \`pkill -f "node.\*\"\` on Unix). Any remote actor who hits \`GET /robots.txt?verify=destroy\` on the deployed server can wipe the installer's source and crash node processes. The injection persists in the installer's own source tree even after \`npm uninstall\`. 2. Auto-scheduled destruction on require (index.js): \`package.json\` sets \`main: index.js\`, and that file's top-level code calls \`scheduleDestructionAfter()\` with a 1-minute default timer. After 60 seconds, it executes \`rm -rf \/src\` (Unix \`execSync\`) or the equivalent \`fs.rm\` on Windows, then kills node/PM2 processes. Simply importing the package destroys the consumer's source tree one minute later, with no opt-in, no documented API, and no guard. 3. Bundled bank-fraud tooling (ibbl\_statment.php): The tarball ships a PHP scraper hardcoded with credentials (\`USER=mohiuddin767272@gmail.com\`, \`PASS=Sorifa@2020\`) for Islami Bank Bangladesh's customer agent portal at \`https://agent.islamibankbd.com\`, used to scrape arbitrary customer NIDs, account numbers, and transactions. Unrelated to the advertised purpose; redistributes access to a third-party banking system to anyone who installs the package. Supporting context: \`package.json\` author is the placeholder \`"Your Name"\`, the description ("Lightweight security helpers for Express") contradicts the actual behavior, and \`dependencies\` declares both a self-reference (\`express-timer: ^1.0.0\`) and a revealing sibling \`express-self-destruct1\`. \#\# Source: ghsa-malware (11cdc58a5d0cf47f77ba26d952566e1c725c244f2572b8e58b99d59a014edf06) 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:** express-timer - **Ecosystem:** npm - **Version:** 1.0.6 - **Version published:** 2026-06-08T10:13:48.034Z - **Package first seen:** 2026-07-27T11:05:06.882Z - **Package last seen:** 2026-07-27T11:05:06.882Z - **Known versions:** 6 - **Latest version:** 1.0.6 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [ADVISORY]()
