In this example, everything prior to the executable file header is not part of the file itself, and hence unnecessary. If that is the case, you can trim the off the data that is not part of the file that you are trying to extract using a hex editor. As shown in the previous screenshot, there is data between the end of the TCP header and the beginning of the executable in the Data section of the frame. You will then have the opportunity to save these bytes as a single file.
To extract a file contained within a single packet, first select the Data portion of the packet (which can be seen in the previous screen shot), then choose Export and Selected Packet Bytes from the File menu. On examining the captured network data, it appeared to be encrypted, with no readable text observed after a Dropbox user account logged in. There was no evidence of the filenames for the Enron or Dropbox sample files, nor any Dropbox user credentials seen in the network traffic. However, no Enron sample data files or the Dropbox sample files were seen in the network traffic.

When the client software was used, the URL name seen in the network capture commenced with “v-client” or “client.” When a browser was used, the URL commenced with “v-Network Miner was used to rebuild files from the captured packets, and Dropbox webpage icon files, such as “landingboxbig.png,” were observed. Viewing the network data, it appeared there were different URL names when using Dropbox client software in comparison with using a web browser, even if the same IP number was used. OCSP is the Online Certificate Status Protocol, used by VeriSign/Thawte. and according to the URL name were related to and ocsp.digicert. Amazon Web Services EC2 was also listed for many URLs, with additional information referencing Dropbox, such as “photos1.dropbox,” “photos2.dropbox,” and “photos3.dropbox.” IP numbers also observed in the packet captures are registered to SoftLayer Technologies and WestHost Inc.

When the Dropbox Windows client software was downloaded, the URL name made reference to Amazon Cloudfront. See Table 4.3 for a list of IP number ranges and the registered owner for the range. IP numbers allocated to AmazonAWS, the Amazon Web Services (EC2) service, were then observed. The next IPs accessed were in the range of 74.125.0.0–74.125.255.255 (which are registered to Google) and indicate Google Analytics services. Certificates were observed from VeriSign/Thawte services. When accessing Dropbox accounts using the client software or a web browser, a session with an IP in the range 199.47.216.0–199.47.219.255 (registered to Dropbox), was first established on Port 80, and then a session with an IP in the range 199.7.48.0–199.7.63.255 or 199.16.80.0–199.16.95.255 on Port 80 then Port 443, which is registered to VeriSign/Thawte.
Network traffic was seen on TCP Port 80 (HTTP) and 443 (HTTPS) only.

Analysis of the network traffic capture files was undertaken using Network Miner v1.0 and Wireshark Portable 1.6.5 to determine what data remnants were available when Dropbox is used in the circumstances of the research. Network traffic capture is a potential source of relevant information and is a process available to a range of government agencies which have the legal authority to undertake this type of monitoring and interception of data ( Kisswani, 2010).
