When displaying section data, PE-Bear uses IMAGE_SECTION_HEADER.PointerToRawData to find the section data in the file. In reality, when Windows loads the file, if the section file offset is not aligned to IMAGE_OPTIONAL_HEADER.FileAlignment, it will be rounded up to the next aligned address and loaded there. A malicious binary can use this inconsistency to display incorrect section data.

Btw, CFF Explorer falls for this too. IDA Pro displays a warning that it has detected a section that is not aligned and refuses to handle the section header.
