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. When the engine runs, every completed agent turn causes its local transcript to be uploaded. The upload includes credential metadata and is sent to a dynamically supplied remote upload URL. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-11T10:53:40.936Z - **Finished:** 2026-09-11T10:54:54.494Z - **Download time:** 520 ms - **Static scan time:** 14756 ms - **AI review time:** 58280 ms - **Total time:** 73558 ms The recorded confidence comes from the underlying analysis.

The upload includes credential metadata and is sent to a dynamically supplied remote upload URL. - **Trigger:** Run replicas-engine in a configured workspace and complete an agent chat turn. - **Impact:** Private chat content and associated credential metadata can leave the workspace without a per-upload user action. - **Evidence paths:** dist/src/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T10:54:54.494Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic chat-transcript collection and remote upload. - **Attack narrative:** The executable starts an engine that invokes uploadChatTranscript after each agent turn. That function reads the local transcript, adds the selected agent credential object to metadata, requests an upload URL from its configured server, and uploads transcript data to the returned location. Separately, its warm-hook service executes supplied hook text with Bash. There is no npm install lifecycle trigger, but the runtime behavior is a concrete automatic data-export capability. - **Rationale:** Source inspection confirms automatic upload of agent transcripts and credential metadata to server-directed endpoints during normal runtime. This is concrete data exfiltration behavior, not merely a static scanner match. - **Files touched:** provider-specific chat history .jsonl files ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The running engine automatically uploads a chat transcript when each agent turn finishes., Transcript upload reads the local transcript and includes the selected agent credential object in metadata., The code obtains a server-provided upload URL and sends transcript pages to it., The engine also executes configured warm-hook text through a Bash login shell. - **Evidence against:** package.json has no npm preinstall, install, or postinstall hook., The behavior requires the package executable to run in a configured Replicas workspace. ## Affected versions and remediation This report applies to replicas-engine@0.1.804. - Avoid installing replicas-engine@0.1.804. 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.
