A trusted looking file can carry a second payload inside it, sometimes without breaking its signature. See how MITRE describes it and how to spot the hidden passenger.
Remove symbols and strings from a binary and reverse engineers lose their map. Learn how MITRE describes it and which context clues still stand out.
