Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. When a caller invokes initMFA and refreshes MFA, the package submits supplied Discord credentials and returns reusable MFA authorization headers. This is a dangerous account-automation capability, although the inspected code does not exfiltrate to a non-Discord destination. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-09-09T21:39:23.798Z - **Finished:** 2026-09-09T21:40:04.168Z - **Download time:** 511 ms - **Static scan time:** 81 ms - **AI review time:** 39778 ms - **Total time:** 40370 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:** When a caller invokes initMFA and refreshes MFA, the package submits supplied Discord credentials and returns reusable MFA authorization headers. This is a dangerous account-automation capability, although the inspected code does not exfiltrate to a non-Discord destination. - **Trigger:** A caller invokes initMFA with a Discord token and password, then calls refreshMfa or uses the returned controller. - **Impact:** It can facilitate automated use of a supplied Discord account's MFA authorization and exposes those credentials to interception if TLS validation is bypassed. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-09T21:40:04.168Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automated Discord MFA completion and authorization-header generation with disabled TLS validation. - **Rationale:** The source implements a concrete MFA-automation capability and weakens TLS verification, so it is unsafe to treat as ordinary authentication tooling. No install-time behavior or confirmed third-party exfiltration was found. - **Network endpoints:** discord.com, canary.discord.com, ptb.discord.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for block:** The manifest advertises an MFA-bypass capability., The library sends supplied account credentials to Discord's MFA completion endpoint., The TLS client disables certificate validation., It exposes MFA authorization headers intended for subsequent Discord requests. - **Evidence against:** There are no preinstall, install, or postinstall lifecycle hooks., The inspected credential requests target Discord hosts only; no third-party exfiltration endpoint was found., No source code executes the generic download helper or writes harvested data to disk. ## Affected versions and remediation This report applies to discord-mfa-solver@1.0.0. - Avoid installing discord-mfa-solver@1.0.0. 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.
