If you follow this blog, you know that I did an article on the first stable release of Namp http://www.pccybertek.com/2010/01/nmap-5-20-released yesterday. Now that it has been out for a week, Fydor has already released another update, Namp 5.21 which is also a stable
release and not a beta. It’s mainly just a bug fix release. So I have updated the download section here with a link to the 5.21 release, which is on the right column about 3/4 of the way down the page. My download link is directly to the file on the insecure.org website or you can go to the Nmap download page yourself.

But I don’t want to just tell you about the update, I’d like to offer you some more since you took the time to stop by here. So here is a link to Iron Geek’s Baisc Nmap Tutorial video. And if already know the basics and would like to move on to some more advanced lesson, here is Iron Geek’s Nmap Video Tutorial 2: Port Scan Boogaloo Happy port knocking.

Some how this one slipped by me because it was published by Adobe on the 19th.

Critical vulnerabilities have been identified in Adobe Shockwave Player 11.5.2.602 and earlier versions, on the Windows and Macintosh operating systems. The vulnerabilities could allow an attacker, who successfully exploits the vulnerabilities, to run malicious code on the affected system. Adobe has provided a solution for the reported vulnerabilities. It is recommended that users update their installations to the latest version using the instructions provided above.

This update resolves a buffer overflow vulnerability that could potentially lead to code execution (CVE-2009-4002).

This update resolves multiple integer overflow vulnerabilities that could potentially lead to code execution (CVE-2009-4003).

Fydor has released Nmap 5.20. This is the first stable release, or non beta release, of Nmap since July 2009. And like usual, it has a lot of nice improvements and upgrades. If I could only have one security tool, Nmap would be it. It’s the first, and sometimes the only, program I run when I want to do any kind of security audit or if I want an inventory of  the LAN and which services are running .

t’s been about a year since one of the best pen testing tools has seen an upgrade to the framework. Metasploit Framework 3.3 is now available. Not only does it support Linux, Windows, OS X, and many versions of BSD, but now it also supports Windows 7. And according to the website this release has 446 exploits, 216 auxiliary modules, and hundreds of payloads, including an in-memory VNC service and the Meterpreter. However one of the new features that I’m pleased about is you can now run a full console version in Windows using Cygwin which is how I like to run nmap when I’m on my Windows computers, and RXVT. To be honest, I haven’t fired up any of my Linux machines in a while. I just boot from a Linux Live CD most the time but I digress.
The Windows installer works on all versions of Windows from 2000 to Windows 7 and the Linux installer works on most versions of Linux released in the last five years.
I’d like to point out, this is not a toy. This is the bad boy of penetration testing tools. I love using this because I know that if I can’t get into the system I’m testing with it, I can feel pretty confident that system is pretty secure. I wouldn’t go so far as to say that I’m 100% secure because I’ve been doing this long enough to know there is no such thing. But if you can’t successfully attack one of your computers with this, then chances are neither can the script kiddies.

Unable to attend DefCon this year, I’ve been following it on twitter. There was a talk about how insecure Firefox extensions are.

@ramereth word to the wise: DO NOT trust any firefox extension. assume they can grab and do anything including executing other code #defcon

Just one of many tweets talking about how scary the talk was. So until I can get more information on this, I’m disabling most of my Firefox extensions. Could this be Firefox’s vulnerability equivalent to Internet Explorer’s active-x? Ironically, I’ve been using Google’s Chrome browser lately. I’m liking it more and more. I was just switching back to Firefox because it has a couple extensions I use a lot. But now that they might not be safe, it looks like Chrome is going to be set as my default browser. At least until I find out more about these Firefox extension exploits.

Seeing how this talk was given today, I suspect there will soon be a rash of these exploits and figured I should pass on the info I have even though it’ sketchy at best at this point. To disable your extensions in Firefox, just go to Tools, then addons, then extensions, and uninstall or disable them.

Yes, that’s right. The essential network scanner, nmap, has made it to version 5. If you are unfamiliar with nmap, it’s a must have tool for anyone who does anything with networks. It’s the greatest port scanner around. And you can get it for just about any OS. But nmap is much more than just a port scanner. It can be used for more than just seeing what ports are open. You can also use it for its OS detection, among other things, and you can even use it to find the conficker virus on remote computers. It’s available as a command line tool and for those who prefer a gui, it also comes with zenmap which is a graphical front end for it.

My thanks to Fydor and the nmap development team for constantly updating this awesome tool and never being satisfied with the status quo. Now let me quote insecure.org

July 16, 2009 — Insecure.Org is pleased to announce the immediate, free availability of the Nmap Security Scanner version 5.00 from http://nmap.org/. This is the first stable release since 4.76 (last September), and the first major release since the 4.50 release in 2007. Dozens of development releases led up to this.

Considering all the changes, we consider this the most important Nmap release since 1997, and we recommend that all current users upgrade.

You can find a list of the changes here and be sure to download it.

Looks like there is another ActiveX vulnerability. If you are unfamiliar with ActiveX, basically, a web page can do stuff like read and write files when you use Internet Explorer and allow ActiveX options. This nice for the Microsoft Update site to see which files it needs to update, but that’s about it in my opinion. Sure, there is a pop-up that asks you if you want to allow a website to use ActiveX but history shows that too many people allow ActiveX when the shouldn’t. There is an unbelievable amount of attacks that use ActiveX. That’s one of the main reasons I use Firefox instead of Internet Explorer, it doesn’t have ActiveX so you don’t have to worry. Google’s Chrome is another web browsers that doesn’t have ActiveX.

Our friends over at the Internet Storm Center are keeping an active eye on this new vulnerability. You can read all about it and follow their updates here. So do your Microsoft Updates, several just came out, and if you really want to be safe, stop using Internet Explorer or use it as little as possible and switch to Firefox, Chrome or even Opera. Stay Safe.

I’m sure you have all seen this before. Your surfing along, when all of a sudden, you get a pop-up that alerts you that your computer is infected! YIKES! What to do!??! Ah, you can just download a “free” program that will fix it for you. I’d hope you already know, this is a scam. It’s one of two things. You can either download a legit program that will scan your computer, tell you how badly infected it is and you can purchase a full version of the program to remove all your “infections.” Just in case your not really infected, these programs will increase your infection count by adding your cookies to the list. Pretty good way to jack up the numbers, but I wouldn’t call cookies an infection. And I sure don’t have to buy any program to remove them. The other thing that could happen, and probably will is, you will download a program that will then install it’s own addware. Turns out they have a name for this stuff now, and that name is Scareware.

Turns out many people are still falling for this scam. I had to clean my parents computer up, from one of these. Try doing it over VNC, and you may have your patience tested like I did. Anyways, the old folks aren’t the only ones falling for this, and now their is a new variation. Spware Protect 2009, is the new breed of scareware. Not only does it con you by getting you to install it, it actually does damage to get you to “purchase” it for $49.99 and install a trojan downloader. Meanwhile it increases the pop ups telling you how infected your computer is. So you order the program with your credit card and guess what, you just gave them your credit card number, no hacking needed. A local electronics store, with the initials RS, got hit by it and from what I could get out of them, sounds like the whole corp has been infected through their network.

Since I first found out about this last week, I’ve found out that it’s now also being installed by the conficker virus. At first I was thinking, wouldn’t people be suspicious if there was a new piece of software, on their computer? I sure as hell would. Then I started thinking about it, in a corporate situation. Some poor schmuck, in accounting or where ever, could think it was installed by their IT Dept. So the keylogger installed would run until the computer crashed. The one good thing is, the domain that was selling Spyware Protect 2009 is gone. Keep an eye out for variations with new names and the same or slightly modified interface.

With all the media hype about conficker, I thought you might like a good collection of trustworthy resources. Beware of websites that have recently registered as “conficker help.” In fact, just avoid them all together. There’s also reports of malicious software masquerading as detection and cleaning tools for Conficker-infected computers, as well as spam offering the same.

There’s no need to try and figure out what’s safe or real and what has more sinister plans in mind. The good folks at dshield.org have been keeping an updated list of third party information on conficker. Here you can find plenty of free conficker detection and removal tools, general information and the microsoft patch. That should help keep you updated, safe and informed.

I’ve also found out about one other real neat way of detecting it, but it’s for more advanced users, so I’m going to make a seperate post about it.
