Which versions of collecters are malicious?

The following PyPI versions of collecters are flagged malicious: 1.0.1. Treat any of these as compromised.

How do I remediate collecters if I installed it?

collecters 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 collecters — how do I know if it already compromised me?

If collecters 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 collecters part of a known attack campaign?

Yes — collecters is associated with the 2025-11-spellcheckers 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 collecters across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for collecters (version 1.0.1).

What this malware does

Packages contain hidden code that is effectively run during importing or using the library, and downloads second stage code. Then, a process running in background periodically connects to a remote host and waits for next code to execute

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

Campaign: 2025-11-spellcheckers

Reasons (based on the campaign):

obfuscation
Downloads and executes a remote malicious script.
The package contains code to execute remote commands (probably limited to a specific set) on the victim's machine.

Detect & block this

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