Pytosquatting, Supply Chain Risk, and the Slovak National Security Bureau

So most of you will have the Slovak ‘NBU’ on your RSS speed-dial, but I found I was a bit behind on my reading of it. As I was catching up, skcsirt-sa-20170909-pypi caught my eye. In a nutshell, its around a phenomena called ‘typo-squatting’. In this case, Python-package name squatting (called pytosquatting).

So there is a popular package ‘urllib2’. The developers moved on to version 3 (urllib3), deleting the old one. Someone moved in and registered ‘urllib’ and ‘urrlib2’. In turn other unwitting people like you and I would do a ‘pip install urllib’ or ‘import urrlib’. Done, right? Wrong! It behaved properly (so you didn’t notice) and then… well… had side-affects you didn’t want. Other typos included ‘urlib3’ (dropped ‘l’) etc.

Here’s a few they highlighted.

    Thanks for the heads up. A quick helper check that they provided, here for quick access:

    pip list –format=legacy | egrep ‘^(acqusition|apidev-coop|bzip|crypt|django-server|pwd|setup-tools|telnet|urlib3|urllib) ‘

    pip install safety-db safety
    safety check –full-report
