Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Disclosure of secrets, npm/git/cloud/container/Kubernetes credentials, complete environment variables, and browser wallet extension data from the install host. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Block by default - **Public report status:** Published - **Threat category:** Credential Exfiltration - **Selected version:** 4.3.9 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM AI independently confirmed malicious behavior in this version and supplies the Firewall block. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Direct source inspection confirms deliberate unconsented install-time secret harvesting and exfiltration unrelated to the advertised debug wrapper. The sandbox evasion and self-deletion further support malicious intent. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-07-05T23:57:57.904Z - **Finished:** 2026-07-05T23:58:34.700Z - **Download time:** 255 ms - **Static scan time:** 85 ms - **AI review time:** 36455 ms - **Total time:** 36796 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The package performs install-time credential and wallet theft. It harvests environment variables, developer/cloud credential files, and Chrome wallet extension storage, then sends them to Telegram. - **Trigger:** npm install of debugcli@4.3.9 via package.json postinstall - **Impact:** Disclosure of secrets, npm/git/cloud/container/Kubernetes credentials, complete environment variables, and browser wallet extension data from the install host. - **Evidence paths:** package.json, install.js, index.js - **Review source:** ai\_review - **Reviewed:** 2026-07-05T23:58:34.700Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented postinstall credential exfiltration - **Attack narrative:** During npm postinstall, install.js avoids sandbox-like hosts, takes a temp lock, decodes Telegram bot credentials using registry metadata, gathers secrets from process.env and common credential files, discovers Chrome MetaMask/Trust Wallet extension storage, compresses the stolen data, sends it to Telegram, and attempts to delete itself. - **Rationale:** Direct source inspection confirms deliberate unconsented install-time secret harvesting and exfiltration unrelated to the advertised debug wrapper. The sandbox evasion and self-deletion further support malicious intent. - **Files touched:** package.json, install.js, index.js, ~/.aws/credentials, ~/.aws/config, ~/.npmrc, .npmrc, ~/.gitconfig, ~/.git-credentials, ~/.kube/config, ~/.config/gcloud/application\_default\_credentials.json, ~/.docker/config.json, ~/.ssh/config, ~/.pypirc, ~/.netrc - **Network endpoints:** registry.npmjs.org, api.telegram.org ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json runs postinstall: node install.js, install.js has sandbox checks and a per-host temp lock before execution, install.js collects sensitive env vars and then env\_all from process.env, install.js reads credential files such as .aws, .npmrc, .git-credentials, kube, gcloud, docker, ssh, .pypirc, .netrc, install.js locates MetaMask/Trust Wallet Chrome extension storage and archives it with tar or PowerShell, install.js exfiltrates summaries, gzipped data, and wallet archives to api.telegram.org - **Evidence against:** index.js is a benign require('debug') wrapper, No malicious logic found outside install.js ## Affected versions and remediation This report applies to debugcli@4.3.9. - Avoid installing debugcli@4.3.9. 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.
