PCode Decompiled VBA Stored VBA Partial Diff. Full Diff. Missing P-Code: The Office document under analysis has been identified as having undergone VBA Purging techniques, as the P-Code block within the document is currently inaccessible. As a result, the decompilation of the code was not possible, leaving only the stored code available in textual format for analysis. VBA Purging essentially involves the elimination of the PerformanceCache section from the module streams. To fully erase any traces of the P-Code section, the MODULEOFFSET between the two sections is adjusted to 0 by altering the _VBA_PROJECT stream, and all SRP streams that also house PerformanceCache data are removed. Following the removal of the compiled code, antivirus engines and Yara rules, which depend on precise string matches, are rendered ineffective. This allows macros to bypass them effortlessly, owing to the compressed format of the remaining source code.
