File hash explained
Hashes are the output of a hashing algorithm like MD5 (Message Digest 5) or SHA (Secure Hash Algorithm). These algorithms essentially aim to produce a unique, fixed-length string – the hash value, or “message digest” – for any given piece of data or “message”. As every file on a computer is, ultimately, just data that … See more Hashes cannot be reversed, so simply knowing the result of a file’s hash from a hashing algorithm does not allow you to reconstruct the file’s … See more Given a unique identifier for a file, we can use this information in a number of ways. Some legacy AV solutions rely entirely on hash values to determine if a file is malicious or not, … See more Hashes are a fundamental tool in computer security as they can reliably tell us when two files are identical, so long as we use secure hashing algorithms that avoid collisions. Even so, as we have seen above, two files can … See more Threat hunting is also made easier thanks to hash values.
