Blast From the Past: D-Link Probes in the HITME

We got a few scans for an old D-Link router vulnerability that dates back to 2009. It’s interesting to me how long scanning signatures live in online malware and scanning tools. This has lived for quite a while. 

Here are the catches from a HoneyPoint Personal Edition I have deployed at home and exposed to the Internet. Mostly, this is just to give folks looking at the scans in their logs an idea of what is going on. (xxx) replaces the IP address… 

2013-10-02 02:46:13 – HoneyPoint received a probe from 71.103.222.99 on port 80 Input: GET /HNAP1/ HTTP/1.1 Host: xxxx User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Win32) WebWasher 3.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-US,en;q=0.5 Accept-Encoding: gzip, deflate Referer: http://xxxx/ Authorization: Basic YWRtaW46dWA+NXhZQlU1d2VR Connection: keep-alive

2013-10-02 03:22:13 – HoneyPoint received a probe from 71.224.194.47 on port 80 Input: GET /HNAP1/ HTTP/1.1 Host: xxxx User-Agent: Opera/6.x (Linux 2.4.8-26mdk i686; U) [en] Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-US,en;q=0.5 Accept-Encoding: gzip, deflate Referer: http://xxxx/ Authorization: Basic YWRtaW46InkwYi4qMF5wL05G Connection: keep-alive

This probe is often associated with vulnerable D-Link routers, usually older ones, those made between 2006 and mid-2010. The original release and proof of concept exploit tool is here. The scan has also been embedded into several scanning tools and a couple of pieces of malware, so it continues to thrive.

Obviously, if you are using these older D-Link routers at home or in a business, make sure they are updated to the latest firmware, and they may still be vulnerable, depending on their age. You should replace older routers with this vulnerability if they can not be upgraded. 

The proof of concept exploit also contains an excellent doc that explains the HNAP protocol in detail. Give it a read. It’s dated, but remains very interesting.

PS – As an aside, I also ran the exploit through VirusTotal to see what kind of detection rate it gets. 0% was the answer, at least for that basic exploit PoC. 

Review of Puppy Linux 5.0

Lucid Puppy Linux 5.0 was released back in May of 2010, but as one of my favorite distros, I have been playing with it heavily since then. I have been so impressed with the new version that I wanted to take a moment and write a quick review of this release.

You can find the official release page here, along with download information.

First, let me say that I have really come to love Puppy Linux over the last several years. I use it as a LiveCD/USB platform for secure on the go browsing, a Linux OS for old hardware that I donate to a variety of folks and causes, and as a platform for using HoneyPoint as a scattersensor. I like the ease of use, wide range of hardware support, and small footprint. All of these make this a very workable Linux distro.

This version especially seems to be stable, fast, and capable. I have taken to running it from a bootable USB drive and the performance has been very nice. Being able to drop these onto untrusted systems and use them as a browser, VPN client, and productivity tool has been handy. Using HoneyPoint Personal Edition, the nmap plugins and some other Puppy installs of security tools gives me a great platform for working incidents, gaining visibility and catching rogue scans, probes and malware that are in circulation when I pull in to help a client. Over and over again, the distro has proven itself to be a very powerful tool for me.

I suggest you take a look at the distro, LiveCD or USB and see how it can help you. I think you’ll find it fun, easy to use, and quite addicting. The pictures of the puppies don’t hurt either. 🙂
