pip install malware: it’s that easy. Almost all projects depend on external packages, but did you know how easy it can be to install something nasty instead of the dependency you want? I'll be showing this live, as I make malware and install it from PyPI onto my own computer during the talk!
You might remember classic typosquatting examples like goggle.com, but it’s now common to see malicious code hidden in spoofed or otherwise fraudulent PyPI packages or nested dependencies. Malware developers can also use techniques like starjacking to appear legitimate, so these unpleasant packages become even more difficult to spot. It’s estimated that over 3% of packages on PyPI could be using this technique.
By the end of this talk, you’ll know how to protect yourself when installing and updating dependencies and you’ll leave with a checklist to follow to help you stay safe in future.
