Toward the Detection of Polyglot Files. (arXiv:2203.07561v1 [cs.CR])

Standardized file formats play a key role in the development and use of
computer software. However, it is possible to abuse standardized file formats
by creating a file that is valid in multiple file formats. The resulting
polyglot (many languages) file can confound file format identification,
allowing elements of the file to evade analysis.This is especially problematic
for malware detection systems that rely on file format identification for
feature extraction. File format identification processes that depend on file
signatures can …
