What is a hash?

When hackers talk about passing the hash, they are referring to the hashed value of the password that was obtained from an exploited device. The process of hashing a password works by utilizing a cryptographic algorithm that transforms plaintext into a fixed length string of characters. This string of characters is called a fingerprint. A method known as salting makes cracking a hashed password much harder. Salting a hashed password works by adding a random string of characters before the password is hashed. A hash is considered to be a one-way function, because it cannot be reversed.

Hash tables are often used to index data for fingerprinting. An example of an MD5 hash looks like this, 8743b52063cd84097a65d1633f5c74f5. An example of a salted MD5 hash is 01dfae6e5d4d90d9892622325959afbe:7050461. The seven numbers at the end of the string is a random set of numbers added before the hash string is...

Michael McLafferty

Michael McLafferty has been researching on cyber security and applied ethical hacking for over 6 years. His interest in cyber security started in 2010. At the time, he was creating search engine optimization scripts for various small businesses. His clients would also ask him to secure their websites, which led him to find his passion in cyber security instead of search engine optimization.

He would provide network and endpoint security advice as well as social engineering awareness training to employees and individuals. He is also a paid cyber security researcher, sponsored by local businesses to further the advancement of cyber security methods and applied knowledge. He is the co-founder of an open society of ethical hackers that meets weekly to discuss and apply new cyber security skills. They have full access to both a lab and cutting-edge ethical hacking equipment, to develop new methods in offensive security. He is also an inventor. He and his business partner have patents pending on various cyber security tools and software. They continue with their research with great passion and drive.
