NetworkMiner 2.2 is faster, better and stronger than ever before! The PCAP parsing speed has more than doubled and even more details are now extracted from analyzed packet capture files.
The improved parsing speed of NetworkMiner 2.2 can be enjoyed regardless if NetworkMiner is run in Windows or Linux, additionally the user interface is more responsive and flickers way less when capture files are being loaded.
User Interface Improvements
The keyword filter available in the Files, Messages, Sessions, DNS and Parameters tabs has been improved so that the rows now can be filtered on a single column of choice by selecting the desired column in a drop-down list. There is also an “Any column” option, which can be used to search for the keyword in all columns.
The Messages tab has also received an additional feature, which allows the filter keyword to be matched against the text in the message body as well as email headers when the “Any column” option is selected. This allows for an efficient analysis of messages (such as emails sent/received through SMTP, POP3 and IMAP as well as IRC messages and some HTTP based messaging platforms), since the messages can be filtered just like in a normal e-mail client.
We have also given up on using local timestamp formats; timestamps are now instead shown using the
NetworkMiner 2.2 comes with a parser for the Remote Desktop Protocol (RDP), which rides on top of COTP and TPKT. The RDP parser is primarily used in order to extract usernames from RDP cookies and show them on the Credentials tab. This new version also comes with better extraction of SMB1 and SMB2 details, such as NTLM SSP usernames.
One big change that has been made behind the scenes of NetworkMiner is the move from .NET Framework 2.0 to version 4.0. This move doesn’t require any special measures to be taken for most Microsoft Windows users since the 4.0 Framework is typically already installed on these machines. If you’re running NetworkMiner in Linux, however, you might wanna check out our updated blog post on how to install NetworkMiner in Linux.
We have also added an automatic check for new versions of NetworkMiner, which runs every time the tool is started.
This update check can be disabled by adding a
NetworkMiner.exe --noupdatecheck capturefile.pcap
Even though NetworkMiner 2.2 now uses ISO-like time representations NetworkMiner still has to decide which time zone to use
for the timestamps. The default decision has always been to
use the same time zone as the local machine, but
NetworkMiner Professional now additionally comes with an option that allows the user to select whether to use UTC
(as nature intended),
the local time zone or some other custom time zone for displaying timestamps. The time zone setting can be found in the
UPDATE: With the release of NetworkMiner 2.3 the default time zone is now UTC unless the user has specifically selected a different time zone.
The Port-Independent-Protocol-Detection (PIPI) feature in NetworkMiner Pro has been improved for more reliable identification of HTTP, SSH, SOCKS, FTP and SSL sessions running on non-standard port numbers.
CASE / JSON-LD Export
We are happy to announce that the professional edition of NetworkMiner 2.2 now has support for exporting extracted details using the Cyber-investigation Analysis Standard Expression (CASE) format, which is a JSON-LD format for digital forensics data. The CASE export is also available in the command line tool NetworkMinerCLI.
We would like to thank Europol for recommending us to implement the CASE export format in their effort to adopt CASE as a standard digital forensic format. Several other companies in the digital forensics field are currently looking into implementing CASE in their tools, including AccessData, Cellebrite, Guidance, Volatility and XRY. We believe the CASE format will become a popular format for exchanging digital forensic data between tools for digital forensics, log correlation and SIEM solutions.
We will, however, still continue supporting and maintaining the CSV and XML export formats in NetworkMiner Professional and NetworkMinerCLI alongside the new CASE format.
I would like to thank Sebastian Gebhard and Clinton Page for reporting bugs in the Credentials tab and TFTP parsing code that now have been fixed. I would also like to thank Jeff Carrell for providing a capture file that has been used to debug an issue in NetworkMiner’s OpenFlow parser. There are also a couple of users who have suggested new features that have made it into this release of NetworkMiner. Marc Lindike suggested the powerful deep search of extracted messages and Niclas Hirschfeld proposed a new option in the PCAP-over-IP functionality that allows NetworkMiner to receive PCAP data via a remote netcat listener.
Upgrading to Version 2.2
Users who have purchased a license for NetworkMiner Professional 2.x can download a free update to version 2.2 from our customer portal.
Those who instead prefer to use the free and open source version can grab the latest version of NetworkMiner from the official NetworkMiner page.
