![]() ![]() Here Microsoft decided to kick out RC4 encryption in favor of AES encryption (AES-128-CBC with an IV). It will also discuss the changes that are made in the Windows 10 Anniversary Update (3 or v1607). This article will try to explain exactly and in great detail how these hashes can be fully retrieved. However, even the hashes are not stored “ as is“, they are actually found Double Encrypted within the SAM Registry Hive, with parts of the encryption keys in the SYSTEM Registry Hive. They are, of course, not stored in clear text but rather in “ hashed” form and for all recent Windows versions, using the NTLM proprietary (but known) hashing algorithm. Physically they can be found on places like C:\Windows\System32\config\ in files like ‘SAM’ and ‘SYSTEM’. Password are stored on hard drives in something called “Registry Files”. 3.1 Step By Step Example: new NTLM Hash Retrieval (AES Cipher).2.1 Step By Step Example: old NTLM Hash Retrieval (RC4 Cipher). ![]()
