Transferring Shares to a new Server

August 8, 2007

I just came across a great way to transfer the shares from an old server to the new one.  It handles printers as well as folder shares.  NOTE: You may have to go through the shares and update the paths as the drive letters may be different on the new server.  Even with having to do that it will save tons of time which would have been spent creating the shares by hand.

Here is a link to the MS KB:

How to create a self install of the Cisco VPN Client

July 25, 2007

Thought I’d share this with everyone. Keep in mind this is using the OLD version of the Winzip Self Extractor utility… but it still applies.

This is a way to configure a self-installing Cisco VPN client for your end users. It’s very easy to do and very helpful. The normal install of a Cisco VPN client is quite tedious for some end-users to endure. This process makes a single .exe file and allows you to customize install messages, etc.

Use WinZip Self-Extractor tool

Choose Software Installation Option

Provide ZIP file of VPN Client (Run Winzip ahead to create single archive)

Provide user information (That is only what user will see)

Provide silent install keys.

Provide support information

(I’m not including this image because it contained some work-related info and I didn’t feel like editing it). This is self explanatory.

Be sure to check Unzip automatically

Review final information and accept it.

Final install was created, test it now or skip to the end.

That was easy, wasn’t it?

Another Default Password site

July 8, 2007

A few posts back I mentioned a cool site that provided default passwords for thousands of devices and applications.

www.defaultpassword.com

Here’s another, not-so-pretty list. It may include the same entries as the site mentioned earlier, but a quick Find procedure might yield quicker results. It’s ugly, but it’s definitely cool.

Hacking 101: Cain & Abel

June 20, 2007

I came across this awesome utility at work today. Someone needed to desperately crack a Word document for a customer. So he sent out an email to all of the engineers asking if we had any tools (preferably free) to help him crack this document.

A few ideas came up – but by far, this has been the best idea. It may have not helped him out in his case, and that I’m not sure of. But I became curious and checked this tool out myself.

Cain & Abel is a free password recovery tool for Microsoft OS’s.

From their website:

Cain & Abel is a password recovery tool for Microsoft Operating Systems. It allows easy recovery of various kind of passwords by sniffing the network, cracking encrypted passwords using Dictionary, Brute-Force and Cryptanalysis attacks, recording VoIP conversations, decoding scrambled passwords, recovering wireless network keys, revealing password boxes, uncovering cached passwords and analyzing routing protocols. The program does not exploit any software vulnerabilities or bugs that could not be fixed with little effort. It covers some security aspects/weakness present in protocol’s standards, authentication methods and caching mechanisms; its main purpose is the simplified recovery of passwords and credentials from various sources, however it also ships some “non standard” utilities for Microsoft Windows users.

Cain & Abel has been developed in the hope that it will be useful for network administrators, teachers, security consultants/professionals, forensic staff, security software vendors, professional penetration tester and everyone else that plans to use it for ethical reasons. The author will not help or support any illegal activity done with this program. Be warned that there is the possibility that you will cause damages and/or loss of data using this software and that in no events shall the author be liable for such damages or loss of data. Please carefully read the License Agreement included in the program before using it.

The latest version is faster and contains a lot of new features like APR (Arp Poison Routing) which enables sniffing on switched LANs and Man-in-the-Middle attacks. The sniffer in this version can also analyze encrypted protocols such as SSH-1 and HTTPS, and contains filters to capture credentials from a wide range of authentication mechanisms. The new version also ships routing protocols authentication monitors and routes extractors, dictionary and brute-force crackers for all common hashing algorithms and for several specific authentications, password/hash calculators, cryptanalysis attacks, password decoders and  some not so common utilities related to network and system security.

Some of the new features of this release are:

– Automatic Certificate Collector for FTPS (implicit), IMAPS and POP3S protocols.
– FTPS Man-in-the-Middle Sniffer and password collector.
– POP3S Man-in-the-Middle Sniffer and password collector.
– IMAPS Man-in-the-Middle Sniffer and password collector.
– Added Windows Mail (Vista) Password Decoder for POP3, IMAP, NNTP, SMTP and LDAP accounts.
– Added PTW WEP cracking attack.
– Added Windows Vista support in Wireless Password Decoder.
– Wireless Password Decoder now uses DLL injection under XP.

Download Cain & Abel v 4.9.4 today (works on NT, 2000, and XP). Not sure if Vista is supported, according to the website, it’s not listed so I’m not sure.

Looks like ISA 2004 Service Pack 3 is available on the download site. Personally, I’m going to wait and see what happens from the early adopters before I even consider it.

ISA Server 2004 Service Pack 3 provides increased security, new troubleshooting options and tools available directly from the ISA Server Management console, new diagnostic logging functionality, and enhanced log viewer and log filtering options for ISA Server 2004 Standard Edition and Enterprise Edition. In addition, this service pack adds support for publishing Microsoft Exchange Server 2007 with ISA Server 2004

How to make a CAT5 cable in a pinch

April 11, 2007

At my old job in Buffalo NY I would make CAT 5 cables all the time. I could practically do it in my sleep. But just the other day I had to make (3) 50 foot cables and I seriously was lost. I couldn’t remember exactly how to do it.

So I dug through my trunk of my car and found my cable snips and crimper and went at it. I had to research online quickly how to make a Class-A CAT5 cable. There are two standards, A and B. To tell you the truth, I don’t know why, but there is. I was always told A was the way to go. And I have never failed making a cable. Ok… once.

Anyway, I found this excellent technote and followed it. About 30 minutes later I had 3 working cables.

SO, if you ever need a super long cable (or a super short one), or just don’t feel like spending lots of money on a simple CAT 5 Ethernet cable, get a spool of cable, some connectors, a crimping tool and you can do it all yourself!

Windows XP Wireless Fix

April 8, 2007

Thanks to our buddy Steve over at Freesource Technology for this one. I didn’t know this was available.

Install this update to enhance the Windows XP support for Wi-Fi Protected Access 2 (WPA2) options in Wireless Group Policy (WGP), and to help prevent the Windows wireless client from advertising the wireless networks in its preferred networks list.
