On \`npm install\`, the package's postinstall script (postinstall.js) collects host identifiers and CI context — whoami, os.hostname(), os.platform(), cwd, CI, GITHUB\_REPOSITORY, NODE\_ENV — and sends them off the installer's machine via two channels: an HTTPS GET to \`6v2j7oyzq0ehzolr4303sw1vwm2gqje8.oastify.com\` (a Burp Collaborator out-of-band callback host) at path \`/microsft?\\`, and a DNS lookup of... ## Latest scan - **Scanner version:** external-osv-malicious-v1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 100.0% - **Started:** 2026-06-30T15:00:00.099Z - **Finished:** 2026-06-30T15:00:00.099Z - **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 power-platform-playwright-toolkit@1.0.4. - Avoid installing power-platform-playwright-toolkit@1.0.4. 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% On \`npm install\`, the package's postinstall script (postinstall.js) collects host identifiers and CI context — whoami, os.hostname(), os.platform(), cwd, CI, GITHUB\_REPOSITORY, NODE\_ENV — and sends them off the installer's machine via two channels: an HTTPS GET to \`6v2j7oyzq0ehzolr4303sw1vwm2gqje8.oastify.com\` (a Burp Collaborator out-of-band callback host) at path \`/microsft?\\`, and a DNS lookup of \`\.6v2j7oyzq0ehzolr4303sw1vwm2gqje8.oastify.com\` to leak the username via DNS even when HTTPS egress is blocked. The package name impersonates Microsoft's Power Platform Playwright tooling namespace, and the exfil path token \`microsft\` (note the misspelling) serves as a campaign tag. The script self-describes as a 'security research canary' / 'Takeover By lobo', but installers have not consented to off-host data transmission and the captured data (GitHub repository identifier, CI flag, hostname, username) is direct reconnaissance value to whoever controls the OAST subdomain. \#\# Source: ghsa-malware (737b1098ebca3d62e2482585023769cf25db3b912a8d31a3785466625169db1e) 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:** power-platform-playwright-toolkit - **Ecosystem:** npm - **Version:** 1.0.4 - **Version published:** Not available - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-06-30T15:00:00.099Z - **Known versions:** 1 - **Latest version:** 1.0.4 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [PACKAGE]() - [ADVISORY]()
