Description

An autorun file installed at the root of a C:\ drive is suspicious, as autorun files are typically associated with removable drives.

Attacker's Goals

The Autorun and AutoPlay components of Microsoft Windows operating systems may use 'Autorun.inf' to automatically execute a program (without user interaction). Adversaries can manipulate this mechanism to run a malicious program.

Investigative actions

Read the content of the 'Autorun.inf' file from the root directory folder of the drive (the file may be hidden).
