Which versions of tdata-grabber are malicious?

The following PyPI versions of tdata-grabber are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate tdata-grabber if I installed it?

tdata-grabber 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 tdata-grabber — how do I know if it already compromised me?

If tdata-grabber 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 tdata-grabber part of a known attack campaign?

Yes — tdata-grabber is associated with the 2026-06-telegramlite, IN-MAL-2026-007770 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 tdata-grabber across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for tdata-grabber (version 1.0.0).

What this malware does

Package name explicitly declares its purpose as harvesting Telegram Desktop session data (tdata directory). The tdata folder contains live authenticated Telegram session keys; collecting and exfiltrating it enables full account takeover of the installer's Telegram account by whoever receives the data. Automated tracing of the package contents engaged but its output was withheld by the provider's malware-content safety filter — a signal consistent with the file contents reading as operational session-stealer code. Combined with the self-declared purpose in the package name, the package fits the messaging-session-theft fingerprint (active-attack) rather than any legitimate library shape.

Package exfiltrates data from the Telegram application to a remote location, effectively collecting Telegram sessions.
