HoneyPoint Used to Confirm Skype URL Indexing

Last week, several sources were talking about the indexing of URLs that happen inside supposedly secure and private Skype sessions. There was a bit of press about it and we thought it would be fun to test it out and easy to do with HoneyPoint Personal Edition. Here’s how we did it:

  • First, we stood up a HoneyPoint Personal Edition and dilated port 80 with a web listener. We configured it to look like a default under construction page on an IIS box. We then exposed it to the Internet.
  • In order to cut down on noise from scanning while we were testing, we decided we would use a target page in our test URL of vixennixie.htm, since scanners aren’t generally looking for that page, if we get scanned while we are testing, it won’t interfere with our data gathering and analysis.
  • Next, we created a Skype chat between to members of the team and made sure each of us was configured for full security.
  • Once this was confirmed, we passed the URL: http://target_ip/vixennixe.htm between us. The time was 1:13pm Eastern.
  • Then, we waited.
  • Lo and behold, we got this nearly 12 hours later:

                     2013-05-22 01:09:45 – HoneyPoint received a probe from 65.52.100.214 on port 80 Input: HEAD /vixennixie.htm HTTP/1.1 Host: target_ip Connection: Keep-Alive

I’ll leave it to the reader to decide what they think about the data. You can draw your own conclusions. We just appreciated yet another use for HoneyPoint and a quick and dirty project to play with. Thanks for reading!

Buffer Overflow Ouchies for Skype and HP OpenView

Two traditional buffer overflow vulnerabilities have emerged today. The first is in the Skype product. It suffers from a heap overflow in the skype4com module. Attackers can exploit this by getting users to visit a malicious page, triggering the overflow. Obviously, Skype users should beware of any links, files or other items sent to them through the Skype network. User awareness of issues with trusting Skype content is the best solution, if your organization allows Skype at all.

Skype users should ensure that they are running the most current version, which is protected from this attack.

The second buffer overflow, this one in HP OpenView’s Network Node Manager, only impacts the following versions:

HP OpenView Network Node Manager (OV NNM) 6.41, 7.01, 7.51 running on HP-UX B.11.00, B.11.11, and B.11.23, Solaris, Windows NT, Windows 2000, Windows XP, and Linux

Attackers can leverage this issue to execute arbitrary code on the vulnerable system. Patches are available through the OpenView support site. Patches should be applied as soon as possible!
