Now, there are 4 files I can find through the HTTP filter: 1. A docx file 2. A pdf file 3. A txt file 4. PNG file. I extracted the PNG image file by the following: Right click on the packet - follow - Using TCP - Converted the file from ASCII to raw - Searched for 'FFD8' and 'FFD9 and copy pasted the raw network text to HxD Hex editor and Reviews: 3. · file [filename] shasum -a [filename] The file command returns the type of file. The shasum command will return the file hash, in this case the SHA file hash. Figure 5 shows using these commands in a CLI on a Debian-based Linux host. Figure 5. Determining the file type and hash of our two objects exported from the bltadwin.ru: Brad Duncan. Wireshark provides a variety of options for exporting packet data. This section describes general ways to export data from the main Wireshark application.

You can find the folder where files have been recovered by right-clicking on a file and selecting "Open Folder". In the Picture below you can see this folder. If we get the SHA checksum of the PE files, we can see that the results are exactly the same than using Wireshark. We have got the sames files. Wireshark examines a file's contents to determine its type. Some other protocol analyzers only look at a filename extensions. For example, you might need to use bltadwin.ru extension in order to open a file using the Windows version of Sniffer.
