LastcvRva

LastcvRva is a term used in the context of reverse engineering and malware analysis, specifically within the Windows operating system. It stands for "Last Control Virtual Relative Address." This value is part of the Portable Executable (PE) file format, which is used for executables, object code, DLLs, and other files in Windows.

In a PE file, the LastcvRva field is found in the Debug Directory, which contains information about the debugging information stored in the file. The LastcvRva value points to the last CodeView record in the file. CodeView is a Microsoft debugging format that provides detailed information about the source code, symbols, and types used in the executable.

The LastcvRva field is important for debugging and reverse engineering because it allows tools to locate and parse the debugging information efficiently. By knowing the location of the last CodeView record, analysts can quickly access the relevant debugging data without having to scan through the entire file.

In summary, LastcvRva is a specific field within the PE file format that points to the last CodeView record in the Debug Directory. It is a crucial piece of information for debugging and reverse engineering tasks, enabling efficient access to detailed debugging data.
