How can malware be hidden within legitimate-looking files?
Malware can be hidden within legitimate-looking files by using techniques such as fileless malware, steganography, or file compression. Fileless malware operates in memory without leaving any traces on the disk, making it difficult to detect. Steganography involves hiding malware within images or other digital media files, making it appear harmless. File compression can be used to pack the malware into a compressed archive, making it harder to identify and analyze.
One way to hide malware within legitimate-looking files is by using encryption techniques. You can encrypt the malware code and embed it within a harmless file, making it difficult for antivirus programs to detect. Another method is to use polymorphic malware, which changes its code structure each time it infects a new file, making it more challenging to identify and remove.
