Which versions of remjsonparse are malicious?

The following PyPI versions of remjsonparse are flagged malicious: 0.1.0, 0.1.1, 0.1.2, 0.1.3, 0.1.4, 0.1.6, 0.1.7. Treat any of these as compromised.

How do I remediate remjsonparse if I installed it?

remjsonparse 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.

I already installed remjsonparse — how do I know if it already compromised me?

If remjsonparse 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.

Is remjsonparse part of a known attack campaign?

Yes — remjsonparse is associated with the 2026-03-remjsonparse campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find remjsonparse across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for remjsonparse (7 malicious versions).

Malicious package

remjsonparsePyPI

Advisory published Mar 9, 2026Updated Mar 9, 2026

remjsonparse is a confirmed malicious PyPI package (MAL-2026-1290) that steals credentials and exfiltrates sensitive data (malicious versions 0.1.0, 0.1.1, 0.1.2…). Do not install it — remove it immediately and rotate any exposed credentials.

MAL-2026-1290

Immediate action

Remove the package, then rotate any secrets the build/runtime could reach.

pip uninstall remjsonparse

What this malware does

During import, package starts advanced compromise actions: exfiltrates AWS and git credentials, commands history, security tools in use. After that, the code waits for further commands from C2. The code is also prepared to configure persistence through autostart keys, crontabs or Linux services, as well as to configure new SSH credentials for remote access.

Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.

Campaign: 2026-03-remjsonparse

Reasons (based on the campaign):

The package contains code to execute remote commands (probably limited to a specific set) on the victim's machine.

Detect & block this

O3 blocks remjsonparse-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
