There are various techniques that can be used to protect kernel function pointers that are set at either compile or initialization time, […]

The startup time for the Python interpreter has been discussed by the core developers and others numerous times over the years; optimization efforts are made periodically as well. Startup time can dominate the execution time of command-line programs written in Python, especially if they import a lot of other modules. Python startup time is worse than some ot […]

Maldoc with auto-updated link, (Thu, Aug 17th) Αύγουστος 17, 2017

Yesterday, while hunting, I found another malicious document that (ab)used a Microsoft Word feature: auto-update of links. This feature is enabled by default for any newly created document (that was the case for my Word 2016 version).
