Background
TerraLogger is a self-contained keylogger built by Golden Chickens, a financially driven threat actor. It captures keystrokes with a typical low-level keyboard hook and saves the logs to files on disk. Usually distributed as an OCX file, the malware runs initial execution checks before continuing; once running, it opens a file handle for logging and sets up its keylogger via a SetWindowsHookExA hook, writing captured keystrokes to the open log file and handling special characters as needed. Researchers found five separate TerraLogger samples, indicating minor revisions and ongoing development.
