Malicious PyPI Packages Compromise Telegram Bot Servers in 2026
Between November 2025 and June 2026, a campaign dubbed 'Operation Navy Ghost' targeted Python developers creating Telegram bots by distributing trojanized versions of the Pyrogram library on the Python Package Index (PyPI). These malicious packages, including 'VLifeGram' and 'pyrogram-styled', contained a hidden backdoor that, upon activation, allowed attackers to execute arbitrary code and access sensitive data on compromised servers. The backdoor was designed to operate silently, suppressing errors and disabling logging, thereby granting attackers extensive control over the affected systems. ([bleepingcomputer.com](https://www.bleepingcomputer.com/news/security/malicious-pypi-packages-give-hackers-control-of-telegram-bot-servers/?utm_source=openai)) This incident underscores the persistent threat of supply chain attacks in open-source ecosystems. The exploitation of widely-used libraries like Pyrogram highlights the need for developers to exercise caution when integrating third-party packages. Ensuring the integrity of software dependencies is crucial to prevent unauthorized access and data breaches.
