ShuvGrok: bring Grok into your terminal

AI Security Review

scanned 2mo ago · by lpm-firewall-ai

The source establishes automatic shared AI CLI state mutation and execution of an unavailable platform binary, but does not establish concrete malicious behavior such as exfiltration or destructive action. A warning is warranted for the unresolved lifecycle payload and control-surface change.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review

Trigger

npm installation runs postinstall; invoking shuvgrok runs the materialized binary.

Impact

A package install can alter the local Grok CLI environment and execute an uninspected platform payload.

Mechanism

Postinstall binary deployment and shared Grok configuration mutation.

AI rationale

Evidence

package.jsonbin/postinstall.jsbin/shuvgrok~/.grok/bin/shuvgrok~/.grok/bin/shuvgrok-<version>~/.grok/config.toml

Decision evidence

public snapshot

AI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

An automatic postinstall hook runs package code during npm installation.
The hook modifies the shared Grok home configuration without an explicit setup command.
The command trampoline materializes a platform binary and executes it; the binary payload is outside this snapshot.

Evidence against

No network request, credential collection, or exfiltration logic appears in the inspected JavaScript.
The installer uses a distinct shuvgrok command and writes an installer marker rather than upstream command settings.
No self-dependency or nested lifecycle chain is declared.
