In the var folder there has suddenly appeared a file called "brute-force.ini. Has anyone out there heard of this one. I am running 3 stores on a dedicated server and this file seems to have appeared after the update to 188.8.131.52.
Solved! Go to Solution.
This file is saved when Magento detects failed login attemps to the downloader.
(This feature was introduced on Magento 1.9.3)
