Avoid Security Tool Identification by Adding Data

Description

An adversary adds data to a file to increase the file size beyond what security tools are capable of handling in an attempt to mask their actions. In addition to this, adding data to a file also changes the file's hash, frustrating security tools that look for known bad files by their hash.
