A Proof-of-Concept evolution of Cache Smuggling. This attack conceals an executable payload inside a JPG's Exif data. As a result, image caching (such as that of a Web Browser) can be used to passively download the payload.

As a result, the example loader (chrome_poc.ps1) does not need to make any internet requests to fetch the second stage payload. Instead, it simply extracts it from the Chrome browser's cache.
