This detection rule targets potential DLL sideloading involving the 'appverifUI.dll', which can be indicative of an attempt to execute malicious code by exploiting trusted applications. The rule is triggered when any image ends with '\appverifUI.dll', but will only alert if the image is not loaded from expected legitimate paths ('C:\Windows\SysWOW64\appverif.exe' or 'C:\Windows\System32\appverif.exe') and the loading process occurs from non-standard directories. This helps identify malicious attempts to sideload unauthorized DLLs that could lead to privilege escalation or defense evasion.
