Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. On MangaCopy pages, the installed userscript extracts a login token and forwards it in Authorization headers to a broad list of alternate API hosts. The wildcard cross-origin permission permits these requests. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-12T21:17:13.089Z - **Finished:** 2026-09-12T21:19:20.719Z - **Download time:** 757 ms - **Static scan time:** 5387 ms - **AI review time:** 121485 ms - **Total time:** 127630 ms The recorded confidence comes from the underlying analysis.

The wildcard cross-origin permission permits these requests. - **Trigger:** A user installs the userscript and visits a matching MangaCopy page. - **Impact:** The user's MangaCopy session token can be exposed to the listed third-party hosts, enabling account-session abuse. - **Evidence paths:** ComicRead-AdGuard.user.js - **Review source:** ai\_review - **Reviewed:** 2026-09-12T21:19:20.719Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Cookie-token harvesting followed by cross-origin credential forwarding. - **Attack narrative:** After installation, the userscript activates on MangaCopy. It reads the page's token cookie, builds an Authorization header from it, and passes that header into requests dispatched across a list of alternate API domains. Its unrestricted cross-origin permission allows those requests despite normal browser-origin boundaries. - **Rationale:** Source directly shows a site token copied into Authorization headers and reused for requests to numerous alternate domains. This is concrete credential exfiltration rather than ordinary package setup. - **Files touched:** ComicRead-AdGuard.user.js - **Network endpoints:** mapi.hotmangasg.com, api.2024manga.com, m.manga2025.com, api.manga2025.com, mapi.fgjfghkk.club, mapi.fgjfghkkcenter.club, mapi.elfgjfghkk.club, mapi.hotmangasd.com, mapi.hotmangasf.com, www.manga2026.xyz, www.manga2025.com ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The userscript runs automatically on MangaCopy pages., It reads the site's token cookie and uses it as an Authorization credential., It sends that credential-bearing header to many alternate, unrelated hosts and has unrestricted cross-origin request permission. - **Evidence against:** package.json has no npm preinstall, install, or postinstall hook., The artifact also implements comic-reader features, but those features do not require forwarding a site token to the listed alternate hosts. ## Affected versions and remediation This report applies to @hymbz/comic-read-script@12.14.0. - Avoid installing @hymbz/comic-read-script@12.14.0. 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.
