Python Malware Employs Unicode Trickery to Evade Detection

New Python Malware Alert: How Cybercriminals are Using Unicode to Steal Your Info

Cybersecurity researchers at Phylum have discovered a new type of malware on the Python Package Index (PyPI) website. The malware, named “onyxproxy,” uses Unicode characters to evade detection and is designed to steal developer login credentials and authentication tokens.

The malware was available on PyPI for a week, during which time it was downloaded 183 times. This means that up to 183 developers may be at risk of having their credentials and identity stolen. The malware was distributed through a package called “,” which contains thousands of suspicious code strings using a combination of Unicode characters.

The discovery of the onyxproxy malware also highlights the risk of “typosquatting,” where attackers intentionally use a package name that is very similar to a popular package to trick users into downloading and installing the malware.

In response to the incident, the maintainers of PyPI have taken steps to improve the security of the repository, such as implementing stricter guidelines for package names and adding new tools for detecting malicious packages. The maintainers of affected packages, such as python3-dateutil, have also released updated versions that remove the malware.

Developers and users are reminded to always verify the authenticity of a package before downloading and installing it, and to regularly monitor their systems for any signs of suspicious activity or unauthorized access. Additionally, it is recommended to use security tools such as antivirus software and firewalls to help prevent malware infections.

This incident is also a reminder of the importance of timely and effective response to cybersecurity threats. By quickly identifying and addressing the onyxproxy malware, the maintainers of PyPI were able to limit the damage and prevent further infections. However, in many cases, malware infections can go undetected for long periods of time, causing significant harm to systems and data.

To improve our ability to respond to cybersecurity threats, it is essential for organizations to have robust incident response plans in place. These plans should include clear procedures for detecting and containing threats, as well as mechanisms for communicating with stakeholders and reporting incidents to the appropriate authorities.

In addition to incident response plans, organizations should also invest in security awareness training for employees and implement regular security audits to identify vulnerabilities and assess the effectiveness of security controls.

By taking a proactive approach to cybersecurity, we can better protect our systems and data from the growing threat of malware and other cyber attacks.
