PyPI Repository Under Attack: New Users and Package Uploads Temporarily Stopped

Python developers, both seasoned and newcomers, may have recently encountered an unexpected obstacle. The maintainers of the Python Package Index (PyPI), the official third-party software repository for Python, have temporarily suspended the ability for users to register and upload new packages. This decision comes in the wake of an uptick in malicious activity on the platform, threatening the security and integrity of the Python ecosystem.

The Security Incident

Over the past week, the PyPI administrators noted a surge in the creation of malicious projects and users. This increase proved overwhelming for the team, especially with several PyPI administrators on leave. In response, they made the decision to put a pause on new user registrations and project uploads​.

Unfortunately, the nature of the malware and the threat actors involved in publishing these rogue packages to PyPI remains undisclosed. This lack of detail leaves room for speculation and uncertainty within the Python community. However, the incident has once again highlighted the susceptibility of software registries like PyPI to potential security threats​.

Software Repositories: A Target for Attackers

Software repositories, such as PyPI, have become an attractive target for malicious actors. By poisoning the software supply chain, they can infiltrate developer environments, spreading malware and causing havoc. The recent events on PyPI serve as a reminder of this ongoing threat.

In a related incident, Israeli cybersecurity startup Phylum discovered an active malware campaign. This campaign cleverly used lures themed around OpenAI's ChatGPT to trick developers into downloading a malicious Python module. The module is capable of stealing clipboard content, potentially hijacking cryptocurrency transactions.

Simultaneously, ReversingLabs identified multiple npm packages containing a trojan called TurkoRat. The packages, named nodejs-encrypt-agent and nodejs-cookie-proxy-agent, were found in the npm repository, another popular software registry​.


The recent security threats on PyPI demonstrate the importance of constant vigilance in the developer community. As software registries continue to be targeted, it is critical for developers to ensure the security of their code by using trusted packages and employing best practices in their programming.

For now, the Python community awaits further updates from the PyPI administrators, hoping for a swift resolution and the reinstatement of new user registrations and project uploads. In the meantime, we must continue to learn from these incidents and work together to safeguard our shared resources.
