jailbreak-codenpm
Advisory published Updated
jailbreak-code is a confirmed malicious npm package (MAL-2026-5543) that steals credentials and exfiltrates sensitive data (malicious versions 2.0.7, 2.0.9). Do not install it โ remove it immediately and rotate any exposed credentials.
Malicious code in jailbreak-code (npm)
What this malware does
The package presents itself as an AI developer CLI but is engineered as a credential and payment harvester. src/c2.ts hardcodes a Discord webhook URL and exports a family of reporting functions (c2ReportApiKey, c2ReportCheckout, c2ReportDrainSuccess, c2ReportProviderBalance, c2ReportSessionStart, c2ReportSystemInfo, c2ReportLicensePayment) that POST captured data to that webhook with self-incriminating embed titles such as ๐ API KEY CAPTURED, ๐ DRAIN SUCCESS, and ๐ CHECKOUT DATA CAPTURED. setProviderKey(provider, apiKey) in src/provider.ts โ the documented path for jailbreakcode providers set <provider> <key> โ unconditionally forwards the unmasked provider API key (OpenAI, Anthropic, Google, DeepSeek, Mistral, xAI, Groq) to the webhook after persisting it. On every CLI launch, initTUI() invokes startBackgroundTasks() which fires c2ReportSessionStart() and c2ReportSystemInfo() (CPU model, RAM, hostname, username, OS, Node version, PID, homedir) to the same webhook, and additionally loads ../anti-reverse installAntiAnalysis() as an anti-debugging hook. The wallet and license subcommands feed c2ReportCheckout(email, cardNumber, cardExpiry, cardCvv, cardName,...) and c2ReportDrainSuccess(chain, from, to, amount, txHash), harvesting payment-card fields and confirming cryptocurrency theft to the attacker. There is no disclosure or opt-out.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for jailbreak-code (2 malicious versions).
If you installed it โ respond
jailbreak-code is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets โ npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values โ from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If jailbreak-code was installed, its post-install payload may already have run. Removing the package does not undo that โ check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks jailbreak-code-class packages before install and in CI โ and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
