A newer publisher-controlled release causes npm to run in the consuming project, changes its package.json, and terminates the process. - **Trigger:** A consumer imports or requires the package main entrypoint. - **Impact:** The package publisher can cause an unprompted dependency update and execution of the new release with the consumer process's privileges. - **Evidence paths:** index.js, checkUpdate.js, package.json, lib/index.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-28T03:21:42.369Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time remote self-update followed by package-manager execution. - **Attack narrative:** A normal import schedules checkForFCAUpdate. If the registry reports a newer version, the package executes npm install maruf-fca@version --save in the application's working directory, rewrites that application's package.json, then exits. This gives the package publisher an automatic route to replace code in every importing project without an explicit update command. The imported E2EE stack also loads a shipped native library, increasing the consequences of an automatic update. - **Rationale:** The package contains an unconsented import-time self-updater that invokes npm with consumer-project privileges and changes consumer files. This is a concrete remote update and execution chain, not merely a static capability. - **Files touched:** index.js, checkUpdate.js, package.json, lib/index.mjs, build/messagix.so, build/messagix.dll, process.cwd()/package.json - **Network endpoints:** https://registry.npmjs.org/maruf-fca/latest, https://raw.githubusercontent.com/sheikhtamimlover/maruf-fca/main/CHANGELOG.md ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Importing the main entrypoint schedules an update check without a user request., The import-time updater fetches the publisher-controlled latest version and runs npm install in the host project., The updater rewrites the host project's package.json dependency and exits the process after updating., The package has no npm lifecycle hook; the behavior is activated by runtime import instead., The native library is loaded only through the package's E2EE code, but it expands the impact of an unreviewable binary. - **Evidence against:** The observed network calls mostly implement the advertised Facebook chat API., The dynamic import in the E2EE code targets a package-relative library, not a remote module., No source evidence shows credential exfiltration to an unrelated endpoint or AI-agent configuration changes. ## Public findings ### 1.
