Protect Against Weak Authentication Protocols and Passwords                 Visit Dereks web site dedicated to Windows Auditing and Security Tools, articles, books, forums, and more www. Are you weak Microsoft has gone from very weak password authentication protocols to those that do a sufficient job in protecting the password. L0phtcrack 4 Full Version' title='L0phtcrack 4 Full Version' />With new authentication protocols such as NTLMv. Kerberos, Microsoft provides a secure environment for protecting passwords within your organization. The problem comes into play in that Microsoft still supports the legacy authentication protocols such as Lan Manager and NT Lan Manager. Although you wont usually have computers on your network that support these older authentication protocols, they are still available on your Windows computers. Kerberos is an industry standardized and approved authentication protocol. Kerberos is in its fifth version as defined in the Internet Engineering Task Forces. Start studying Security.

This poses severe security risks and opens up the computer to easy attacks. Authentication Protocols. Microsoft has supported many authentication protocols over the years. Each time they release a new authentication protocol, it adds new features and security enhancements. Along the way, they also keep the legacy authentication protocol in the operating system to support the older computers that dont support the latest and greatest authentication protocols. This legacy support forces the newest operating systems like Windows Server 2. Microsoft supported authentication protocols Lan Manager, NT Lan Manager both versions, and Kerberos. The keys to decrypting all of these authentication protocols and features are really multi fold. First, we must understand what each protocol provides, so make a good evaluation as to how useful it is for the environment. Second, it must be clear as to which operating system supports which authentication protocol. Even if an authentication protocol is weak, it might be required based on the operating systems running on the network. Third, if an insecure authentication protocol is necessary, the methods to protect the password, password hash, and overall network security must be understood. Lan Manager. Lan Manger LM is one of the oldest authentication protocols that Microsoft has used. It was first introduced with Windows 3. The features of LM are not very luxurious and you can quickly see that they pose many security risks just by reading the description of each. The hash is case insensitive. The character set is limited to 1. The hash is broken down into 2 7 character chunks. If the password is shorter than 1. The hash result is a 1. The hash is one way function. NT Lan Manager. NT Lan Manager NTLM was the predecessor to LM and was introduced with Windows NT 3. The reason that a new authentication protocol was required was that there was a new network directory service introduced with this version of the operating system. The new directory service was controlled by the domain controller. NTLM required that the domain controller store the hashed password for the domain user accounts. The features for NTLM are identical to LM, which shows that this protocol is just as weak as LM, it is just implemented a bit differently. NTLMv. 2NTLMv. 2 was not released with an initial operating system debut. It was released within Service Pack SP 4 of Windows NT 4. With the poor password protection of LM and NTLM, Microsoft fixed many of the issues that these older authentication protocols possessed. The features of NTLMv. Passwords can be up to 1. Mutual authentication between the client and server. Provides longer keys to produce the stronger password hash. Kerberos. Kerberos is an industry standardized and approved authentication protocol. Kerberos is in its fifth version as defined in the Internet Engineering Task Forces IETF Request For Comments RFC 1. Microsoft has added some minor features to the Kerberos standard to take full advantage of the protocol in a Windows environment. The key features that Kerberos provides in an Active Directory domain include the following. Kerberos enforces the mutual authentication process by using a ticketing system. The authentication process is handled primarily by the client, reducing the load on the servers. Domain controllers share the authentication load by running as Kerberos Distribution Centers KDCs. No portion of the password is ever transmitted over the network. Attackers are prevented from capturing and replaying packets from the network since the packets are time sensitive. What Authentication Protocol does your OS support It might come as a surprise to you, but not every Windows operating system supports the most secure authentication protocol. This means that if you are running older operating systems, there is a chance that LM is still being supported and used on your network. This should make you feel a bit uncomfortable and uneasy about your overall network security. Here is a list of each OS and the authentication protocols that they support. Windows 9. 5, 9. 8, and Me. Windows 9x, which includes Windows 9. Me, does not support NTLMv. Kerberos by default. Out of the box these operating systems only support LM andor NTLM. Adobe Cc Crack Keygen - Torrent 2017. Since most companies have a portion of the users still running on Windows 9x, this should make you pause and consider the situation at hand. If you do nothing to fix the problem, your network is constantly storing and communicating the very weak LM password hash from computer to computer. To fix this issue, you can install the Active Directory Client Extensions on your Windows 9x computers. This will immediately allow them to support NTLMv. There is nothing that can make a Windows 9x computer support Kerberos. To obtain the Active Directory Client Extensions, download the installation file from http www. Windows NTAs we have already seen, Windows NT rolled out supporting NTLM. Then, in SP4 for Windows NT 4. Microsoft introduced support for NTLMv. The Active Directory Client Extensions would also give the Windows NT computers support for NTLMv. Active Directory domain. Windows 2. 00. 0XP2. Windows 2. 00. 0, XP, and Server 2. Microsoft supports LM, NTLM, NTLMv. Kerberos. These computers will use Kerberos when they are communicating with Active Directory and the members of Active Directory. When these computers are in a workgroup, they will use NTLMv. The LM and NTLM are supported and used when communicating with legacy operating systems that only support these old weak protocols. Defeating Weak Passwords and their Hashes. If you have been living under a rock for the past 1. Windows password hash. These tools are LC5 L0pht. Crack by Stake http www. Rainbow. Crack http www. The two tools are very different from one another in how they approach cracking a password hash to obtain the password. LC5 takes the brute force method to attack the password hash. This requires processing power and time. The tool attacks the password hash to try and decode the hash and determine the original password. LC5 does support hash tables like Rainbow. Crack, but the vendor does not recommend hash tables for more than 2. Rainbow. Crack only works with pre computer hash tables. These tables are stored on large hard drives and can take up TBs of space. The tables are the actual hash of every combination of the character set for any given length password. Since the hash is already known, the tool only needs to do a comparison of the hash table to the password hash from the operating system.
