The problem did not result from a cyber attack or any form of malicious activity, whether directly or indirectly. Rather, it originated from an alteration in the permissions of one of our database systems, leading to the generation of numerous entries into a "feature file" utilized by our Bot Management system.

Consequently, the size of the feature file doubled unexpectedly. Subsequently, the enlarged feature file was distributed to all the machines comprising our network. The program utilized by the machines for diverting network traffic relies on the feature file to continually update our Bot Management system with the latest security threats. However, due to the software's restriction on the feature file size, which was set below its actual capacity, the system encountered a failure.
