Description

A DLL was loaded by an executable from the same folder on a logical CD-ROM device (ISO).

Attacker's Goals

An attacker is attempting to load untrusted code into trusted contexts to avoid detection or escalate privileges.

Investigative actions

  • Investigate the loaded module and verify if it is malicious.
  • Check if the disk is a mounted CD-ROM (for example from an ISO file), and if it contains hidden files and folders.
  • Check the content of an 'autorun.inf' or '
  • .lnk' files if exists.
