Background

Cliick is a package available on PyPI that provides functionality for manipulating clipboard and replacing crypto wallet addresses. It is commonly used in Python applications to enhance user experience and streamline cryptocurrency transactions. However, a recent vulnerability has been discovered in the package, allowing attackers to distribute malicious versions of cliick via PyPI.

In this specific case, an attacker distributed over 900 malicious packages, infecting local browsers with a malicious extension. This extension manipulates the clipboard and replaces crypto wallet addresses, potentially leading to financial loss for users. The malicious packages were identified using the Checkmarx database, which flagged the specific package version (2f108adcf1cfcda89409959e186981b75dc92e82b72b1e28a3d0b11f88e7cef1) as containing the malicious code.
