flycordPyPI

Malicious code in flycord (PyPI)
What this malware does
When the user uses the provided library, this package silently reports basic information and the result of the user's action to a hardcoded, obfuscated URL. Given the lack of an opt-out possibility, collection of usernames, obfuscated target and not disclosing it anywhere, it cannot be classified as telemetry.
Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for flycord (version 1.2.4).
If you installed it — respond
flycord 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 — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If flycord 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 flycord-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
