The threat of cybercrime is becoming increasingly complex and diverse on putting citizen's data or money in danger. Cybercrime threats are often originating from trusted, malicious, or negligent insiders, who have excessive access privileges to sensitive data. The analysis of cybercrime insider investigation presents many opportunities for actionable intelligence on improving the quality and value of digital evidence. There are several advantages of applying Deep Packet Inspection (DPI) methods in cybercrime insider investigation. This paper introduces DPI method that can help investigators in developing new techniques and performing digital investigation process in forensically sound and timely fashion manner. This paper provides a survey of the packet inspection, which can be applied to cybercrime insider investigation.

As recently shown in 2013, Android-driven smartphones and tablet PCs are vulnerable to so-called cold boot attacks. With physical access to an Android device, forensic memory dumps can be acquired with tools like FROST that exploit the remanence effect of DRAM to read out what is left in memory after a short reboot. While FROST can in some configurations be deployed to break full disk encryption, encrypted user partitions are usually wiped during a cold boot attack, such that a post-mortem analysis of main memory remains the only source of digital evidence. Therefore, we provide an in-depth analysis of Android's memory structures for system and application level memory. To leverage FROST in the digital investigation process of Android cases, we provide open-source Volatility plugins to support an automated analysis and extraction of selected Dalvik VM memory structures.
