What defenses exist against the tracker.exe DLL loading technique?
The most straightforward defense is to add tracker.exe to your application whitelisting blacklist. Since it is a Microsoft-signed binary, many whitelisting solutions allow it by default; explicitly blocking it prevents its abuse for DLL injection. Similar blacklisting can be applied to other signed binaries used in bypass techniques, as highlighted in the article.
