Researchers have collaborated to develop a means of storing extensive information in almost any object. The way of storing this information is the same as for living things: in DNA molecules. A further application of the technology would be to conceal information in everyday objects.
Steganography is hiding a file or a message inside of another file.
‘Steghide’ is a pretty useful tool (steganography program) that lets you encrypt and hide a file inside another file’s content, so it’ll be ‘invisible’ to others (under most situations) thus helping while enhancing the security of your sensitive data.
Steganography is increasingly being used by actors creating malware and cyber-espionage tools. Most modern anti-malware solutions provide little, if any, protection from steganography, while any carrier in which a payload can be secretly carried poses a potential threat.
