Which versions of txdpy are malicious?

The following PyPI versions of txdpy are flagged malicious: 2026.5. Treat any of these as compromised.

How do I remediate txdpy if I installed it?

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

If txdpy 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 txdpy part of a known attack campaign?

Yes — txdpy is associated with the IN-MAL-2026-003581 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 txdpy across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for txdpy (version 2026.5).

What this malware does

The package exports a 发送邮件 (send_email) function whose default sender, recipient, and SMTP auth code are hardcoded to the author's QQ account. In txdpy/发送邮件.py lines 14-17, sender_email defaults to '[email protected]', receiver_email defaults to '[email protected]', and password defaults to the embedded QQ SMTP authorization code. A caller invoking this documented API with the minimal signature (subject and body only) silently delivers their message content to the author's inbox via smtp.qq.com using the author's credentials — the API's advertised purpose (generic email sending) does not match its actual behavior (relaying to a fixed author-controlled mailbox). The function is re-exported from init.py, making it part of the package's public surface. Additionally, txdpy/翻译.py:18-20 ships the author's Baidu Translate API credentials (appid 20220712001270949 + secret_key) — author self-harm rather than installer harm, but corroborates a pattern of careless credential handling. A separate quality issue: pyndjs.py:74 evaluates os.popen('where node') as a function default argument, causing shell execution at import time.

Detect & block this

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