We present a brand new edition of our magazine, containing the best tutorials we gathered in the last few years. This issue will be divided into two parts, each with certain topics covered. We decided to do this for your convenience. Everyone gets to browse through each part and choose which topics interest them the most, and those who are not our subscribers will enjoy lower prices for buying separate e-books - everyone wins!
Still, each part contains close to 400 pages of content and a few dozen of articles and step by step tutorials, guides and how-to’s. We believe you will find those issues very useful to have in your storage of choice, without the need to search through all our issues in search for that one perfect article which solves your problems.
Part 2 - this one - has all kinds of guides on mobile forensics, delves deep into network forensic analysis and complements the set with tutorials on SQL server. The topics may not be as diverse as in Part 1, but still you have plenty to read and learn from this one.
Enjoy your reading!

PACKET ANALYSIS WITH WIRESHARK AND PCAP ANALYSIS TOOLS
by Eric A. Vanderburg
Almost every computer today is connected. Their communication with others takes the form of packets which can be analyzed to determine the facts of a case. Packet sniffers are also called as network analyzers as it helps in monitoring every activity that is performed over the Internet. The information from packet sniffing can be used to analyze the data packets that uncover the source of problems in the network. The important feature of packet sniffing is that it captures data that travels through the network, irrespective of the destination. A log file will be generated at the end of every operation performed by the packet sniffer and the log file will contain the information related to the packets.
USING WIRESHARK TO ANALYZE SSL CONFIGURATIONS AND CERTIFICATES
by Larry Greenblatt
With all the talk these days of internet spying and theft, people are becoming increasingly concerned with protecting their information. As Laura Chappell, the founder of Wireshark University, might say, you can have opinions from people on security, but packets don’t lie. In this article I will show you how to use some simple Wireshark display filters and settings to view SSL/TLS capabilities in browsers, the negotiated cipher suite (the asymmetric, symmetric and hashing algorithms in use for the current session) and the information stored in the certificate.

NETWORK BASED FILE CARVING
by Gavin Stroy
File carving is the name of the technique of pulling files out of a stream of bytes without the use of a particular file system; much like finding a word in a word search puzzle. Network based file carving is used to extract files from saved network traffic data that has been collected from tools such as Wireshark or TCPdump. This is useful for extracting viruses to be analyzed, identifying exfiltration, and forensic investigations.
NETWORK FORENSIC WITH WIRESHARK DISCOVERING AND ISOLATING DOS/DDOS ATTACKS
by Yoram Orzach
Denial-of-Service (DoS) or Distributed Denial-of-Service (DDoS) attacks are attempts to make a computing or network resource unavailable to its users. There are various types of DoS/DDoS attacks, some load the network to the point it is blocked for applications traffic, some load servers to that point, and some are more sophisticated and try to “confuse” the application servers with bad data. Although there are various tools for detection and prevention of these types of attacks, good old Wireshark can also be used for this purpose. In this article we will see some important features of Wireshark, were to place it for capturing data, and how to use it to identify attack patterns.
INTRODUCTION TO MOBILE FORENSICS
by Fabio Masa
The production process of the forensic evidence is divided in five main phase: the seizure, the identification, the acquisition and the examination or analysis. Once the data is extracted from a device, different methods of analysis are used based on the underlying case. As each investigation is distinct, it is not possible to have a single definitive procedures for all cases.
ANDROID FORENSICS AND SECURITY LESSON 1: ANDROID APPLICATION STRUCTURE

HACKING INGRESS – ANDROID APPLICATION REVERSE ENGINEERING
by Eran Goldstein
Today we are going to demonstrate a quick reverse engineering and analysis process of an android mobile application called Ingress. Ingress is a near-real time augmented reality massively multiplayer online video game. It was created by Niantic Labs, a startup within Google, for the Android based devices market. The game has a complex science fiction back story which Niantic is revealing in segments. The gameplay consists of establishing “portals” at places of public art, etc., and linking them to create virtual triangular fields over geographic areas. The progress in the game is measured by the number of Mind Units, i.e. people, nominally controlled by each faction (as illustrated on the Intel Map). The necessary links between portals may range from meters to kilometers, or to hundreds of kilometers in operations of considerable logistical complexity. International links and fields are not uncommon, as Ingress has attracted an enthusiastic following in cities worldwide amongst both young and old, to the extent that the gameplay is itself a lifestyle for some, including tattoos.

HOW TO PERFORM SEARCHES, SEIZURES AND INCIDENT RESPONSES ON IPHONES
by Deivison Pinheiro Franco and Nágila Magalhães Cardoso
iPhones collect and store a tremendous amount of evidence about a user’s activities. In many cases one could argue more evidence is collected than the user may want. Locations, messages, contacts, web surfing habits, notes, pictures and more are available on iPhones storage media, many with time stamped data. With this forensic evidence available, and more business being conducted on iPhones, forensic examiners need to be able to successfully and accurately acquire this evidence when requested by authorized authority. By utilizing proven, existing forensic techniques along with specialty tools mentioned in this paper, examiners can collect and present evidence from an iPhone. This evidence can then produce a clear report of the activities performed on the device.

WINDOWS PHONE 7/8 (WP7) DIGITAL FORENSIC INVESTIGATION PROCEDURE AND EVIDENCE RECOVERY TECHNIQUES
by Dr. Roffeh Ehud, International Law Expert in Electronic Evidence
One of the central problems involving technology and legal proceedings is the reliability of evidence presented to the court. This question is made more relevant due to the fact that rapid technological changes make previous legal precedents irrelevant. In other words, the same technology is no longer used to reinforce evidence as this is not the equivalent forensic tool used to extract digital evidence from the new device. Furthermore, the same forensic tool that was evaluated in the past and was found to be reliable with regard to the digital evidence it presents, must now undergo far reaching change in order that it be capable of copping with new technologies. This leads us to the issue as to whether the evidence presented to the court represents the actual events and/or if is it possible to rely absolutely on the evidence.
SIM CARD FORENSICS
by Apurva Rustagi
This article introduces the file-system implemented in Subscriber Identity Module (SIM) cards and the collection of data contents that might be helpful in a forensic investigation. The author, also, provides programming code that is designed to extract some of the important data such as Short Message Service (SMS) traffic and contact information from the SIM Card. A data extraction application would be written in ANSI C.
UNDERSTANDING SIM CARD FORENSICS
by Rohit Shaw
The SIM (subscriber identity module) is a fundamental component of cellular phones. It’s also known as an integrated circuit card (ICC), which is a microcontroller-based access module. It is a physical entity and can be either a subscriber identity module (SIM) or a universal integrated circuit card (UICC). A SIM can be removed from a cellular handset and inserted into another; it allows users to port identity, personal information, and service between devices. All cell phones are expected to incorporate some type of identity module eventually, in part because of this useful property.
