KnowEm Username Search: Social Media, Domains and Trademarks Wireshark: Determining a SMB and NTLM version in a Windows environment « Knowledge for all (and free) ! The last few days I am playing around with wireshark and I must say I enjoy working with this program. It has saved the day for me a couple of times by giving me information that is only retrieved by looking at packet level. In this article I was looking at SMB and NTLM traffic in a windows environment. I noticed that our XP based network was running NTLMv1 that is considered unsecure. Intro NTLM over a Server Message Block (SMB) transport is one of the most common uses of NTLM authentication and encryption. The NT LAN Manager (NTLM) Authentication Protocol is used in Microsoft Windows Networks for authentication between clients and servers. Step 1 and 2 – The SMB protocol negotiates protocol-specific options using the SMB_COM_NEGOTIATE request and response messages. Step 3 – The client sends an SMB_COM_SESSION_SETUP_ANDX request message. Step 4 – The server responds with an SMB_COM_SESSION_SETUP_ANDX response message within which an NTLM CHALLENGE_MESSAGE is embedded. Wiresharking
Yacy - The Peer To Peer Search Engine Defence in Depth: Attacking LM/NTLMv1 Challenge/Response Authentication In Part 1 of the “LM/NTLMv1 Challenge/Response Authentication” series I discussed how both the LANMAN/NTLMv1 protocols operate and the weaknesses that plague these protocols. In this post I will demonstrate how attackers leverage these weaknesses to exploit the LANMAN/NTLMv1 protocols in order to compromise user credentials. For the remainder of this article I will be focusing on attacking the SMB protocol (Windows file sharing) as this is where LANMAN/NTLMv1 is most commonly used. Capturing the Response In order to capture a client’s LANMAN/NTLMv1 response, attackers will often utilise one of two methods: Force the client host to connect to them Conduct a man-in-the-middle (MITM) attack and “sniff” the client’s response To demonstrate these methods, I will be using the Metasploit Framework or Cain and Abel respectively. Metasploit In order for a client host to connect to us, we first need to create a listening SMB service that will accept incoming connections. 1. 2. 3. 4. msf > run 1. 2. 3.
Global - Find search engines from across the world with Search Engine Colossus John The Ripper Hash Formats John the Ripper is a favourite password cracking tool of many pentesters. There is plenty of documentation about its command line options. I’ve encountered the following problems using John the Ripper. These are not problems with the tool itself, but inherent problems with pentesting and password cracking in general. Sometimes I stumble across hashes on a pentest, but don’t recognise the format, don’t know if it’s supported by john, or whether there are multiple “–format” options I should try.The hashes you collect on a pentest sometimes need munging into a different format… but what’s the format john is expecting? These problems can all be sorted with a bit of googling or grepping through the john source code. In the first release of this page I’ve: I haven’t yet done the following: Added reminders on how hashes can be collected.Added information on how to munge the hashes into a format supported by john.

15 Top Search Engines For Research After hours spent scrolling through Google and pulling up endless clickbait results, you’re frustrated with the internet. You have a paper to write, homework to do and things to learn. You know you won’t get away with citing Wikipedia or Buzzfeed in your research paper. With so many resources online, it’s hard to narrow it down and find ones that are not only reliable and useful, but also free for students. 15 scholarly search engines every student should bookmark 1. Google Scholar was created as a tool to congregate scholarly literature on the web. 2. Google Books allows web users to browse an index of thousands of books, from popular titles to old, to find pages that include your search terms. 3. Operated by the company that brings you Word, PowerPoint and Excel, Microsoft Academic is a reliable, comprehensive research tool. 4. 5. Science.gov is operated and maintained by the Office of Science and Technical Information, the same department that collaborates on WorldWideScience.org.
Hacking Embedded Devices: UART Consoles - MWR Labs The ‘Hardware Hacking’ scene has exploded recently, thanks largely to the widespread adoption of devices such as the Arduino and Raspberry PI by the hacking community. Applying hardware hacking techniques during product assessments can often give unrivaled levels of access to hidden or undocumented functionality particularly when reviewing embedded devices such as routers, switches and access points. Prior to his employment with MWR, Hacker Fantastic, a Senior Security Consultant with MWR, reviewed the “SAGEM F@ST2504 Sky Broadband router”, at the time a popular consumer broadband device, and documented his findings in a blog post and presentation titled Hacking Embedded Devices: For Fun and Profit. Matthew has since followed up on his prior work by reviewing the “Virgin Media SuperHub” a Cable Modem/Router used by Virgin Media Cable in the UK and re-visited his assessment of the “SAGEM F@ST2504 Sky Broadband router”.
