Nmap Developers Release a Picture of the Web
iago-vL writes "The Nmap Project recently posted an awesome visualization of the top million site icons (favicons) on the Web, sized by relative popularity of sites. This project used the Nmap Scripting Engine, which is capable of performing discovery, vulnerability detection, and anything else you can imagine with lightning speed. We saw last month how an Nmap developer downloaded 170 million Facebook names, and this month it's a million favicons; I wonder what they'll do next?" -
Taking Apart the Energizer Trojan
iago-vL writes "Researchers at SkullSecurity have written a tutorial on how they reverse engineered the Energizer Trojan and generated an Nmap probe to remotely detect infections. The Energizer Trojan is a great educational tool because its inner workings are very simplistic, and it makes minimal efforts to hide itself or conceal its purpose; it even lists what appears to be the author's name — 'liuhong' — in the source! The article provides an introduction to malware analysis, from infecting a test machine to debugging and disassembling the Trojan to writing the actual probe." -

NetBIOS Design Allows Traffic Redirection
iago-vL writes "Security researchers at SkullSecurity have demonstrated how the NetBIOS protocol allows trivial hijacking due to its design, through the use of a tool called 'nbpoison' (in the package 'nbtool'). If a DNS lookup fails on Windows, the operating system will broadcast a NetBIOS lookup request that anybody can respond to. One vector of attack is against business workstations on an untrusted network, like a hotel; all DNS requests for internal resources can be redirected (Exchange, proxy, WPAD, etc). Other attack vectors are discussed in a related blog post. Although similar attacks exist against DHCP, ARP and many other LAN-based protocols, we all know that untrusted systems on a LAN means game over. NetBIOS poisoning is much quieter and less likely to break other things." -
Using Conficker's Tricks To Root Out Infections
iago-vL writes "Despite having their domain blacklisted by Conficker, the folks at Nmap have released version 4.85BETA8, which promises better detection of the Conficker worm. How? By talking to it on its own peer-to-peer network! By sending encrypted messages to a suspect host, the tools will get Conficker.C and higher to reveal itself. This curious case of using Conficker's own tricks to find it is similar to the last method that we discussed. More information from the author is available, as well as a download for the new release (or, if you're a Conficker refugee, try a mirror instead)." -
