Security Incident at python.org
https://wiki.python.org/moin/WikiAttack2013
The python.org wikis for Python, Jython and the Python Software Foundation (PSF) were subject to a security breach and later attack which caused all of the wiki data to be destroyed on January 5 2013.
An analysis of the incident revealed that an exploit had been planted on our servers possibly as early as July 25 2012, which allowed arbitrary execution of code under the user running the MoinMoin wiki.
