Advisory published Updated
@ikbal_fadilah_vanexa01/vanexa-agent is a confirmed malicious npm package (MAL-2026-13364) that executes malicious code on install (malicious versions 1.1.51, 1.1.52, 1.1.53…). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @ikbal_fadilah_vanexa01/vanexa-agent (npm)
What this malware does
Package ships an agent daemon (vanexa-agent start, entry bin/vanexa-agent.js) that receives commands from a remote phone app and executes them on the installer's host via child_process/spawn, including powershell.exe and inline JS/Python evaluation. Rather than the LAN-only WebSocket architecture described in the README (which claims BYOK with no middleman), the compiled bundle hardcodes two Cloudflare Workers endpoints — vanexa-agent-relay.hanazaki542.workers.dev and vanexa-ai-proxy.hanazaki542.workers.dev — hosted on a personal Cloudflare account (hanazaki542) that does not match the npm publisher (ikbalsakata500445jensen). Commands from the phone client and, via the AI proxy path, user-supplied prompt content and API tokens transit this third-party intermediary before reaching the local execution sinks on the installer's machine. The primary runtime is shipped as V8 bytecode (dist/bundle.jsc) produced from dist/bundle.cjs at postinstall via bytenode.compileFile, and the bin entry loads that bytecode with require(bytecodePath), reducing auditability of the network-driven exec path. The combination — network-sourced commands flowing into local shell/child_process, a hardcoded author-controlled relay whose ownership does not match the publisher, and a bytecode-compiled payload — makes normal operator use of this agent equivalent to granting the relay operator remote command execution on the installer's host.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for @ikbal_fadilah_vanexa01/vanexa-agent (35 malicious versions).
If you installed it — respond
Remove @ikbal_fadilah_vanexa01/vanexa-agent from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If @ikbal_fadilah_vanexa01/vanexa-agent was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks @ikbal_fadilah_vanexa01/vanexa-agent-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
