Malware Insights

The file contains a PNG image with a large encoded payload appended after its end, indicated by the IMAGE_TRAILING_OVERLAY_EXECUTABLE heuristic. This suggests a loader is present to decode and execute the appended data. No specific family could be identified, and the embedded URLs were confirmed benign.

Heuristics 2

  • Loader-delimited encoded payload appended after image end critical IMAGE_TRAILING_OVERLAY_EXECUTABLE
    A valid image is followed by a large appended overlay that begins with a known stego-loader delimiter (INICIO) and is dominated by the base64 alphabet. This is the AutoIt/.NET image-stego-loader carrier shape: a lure image with an encoded PE appended after its logical end for a loader to decode and execute.
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
