PCAP:

FIRST DECISION POINT - YOU FINISH YOUR ANALYSIS BASED ONLY ON THE PCAP

Here's what you should've found when looking at the pcap:

 

Let's go through this, step-by-step.  First, load the pcap in wireshark.  Hopefully, you've set it up as I've described in my tutorial here.  You can find the host name and mac address for this IP address in the DHCP or NetBIOS name service (NBNS) traffic.  See the images below for details:

 

Use http.request for the filter and see the web browsing traffic.  At the botton, you'll find the last few HTTP GET requests for Nuclear EK.

 

The exploit kit should send files in the following sequence:

 

In most exploit kits, including Nuclear, these are all sent from same IP address and domain.  Here are highlights from the pcap, so you can see if the malware payload was delivered.

 

FIRST DECISION POINT - ALTERNATE CHOICE

You want to know what alerts triggered and include them in your report.  What exactly was that malware payload?  With a determined look on your face, you investigate further.  (Careful...  Your face might settle into that look permanently.)  The other analysts are still reviewing events, and someone will notify you if anything else unusual happens.
