ThiefQuest uploads files via unencrypted HTTP.

T1554
Compromise Host Software Binary
MalwareThiefQuest

ThiefQuest searches through the /Users/ folder looking for executable files. For each executable, ThiefQuest prepends a copy of itself to the beginning of the file. When the file is executed, the ThiefQuest code is executed first. ThiefQuest creates a hidden file, copies the original target executable to the file, then executes the new hidden file to maintain the appearance of normal behavior.
