A security professional deals with so many things to safeguard their company or firm from different kinds of attacks. Memory Forensics is also one of them that helps information security professionals to find malicious elements or better known as volatile data in a computer’s memory dump. Now, before jumping to Memory Forensics tools, let’s try to understand what volatile data mean and what remains in the memory dump of a computer.
What is Volatile Data?
When the computer is in the running state, all the clipboard content, browsing data, chat messages, etc remain stored in its temporary memory. These data are called volatile data, which is immediately lost when the computer shuts down. Suppose, you are working on a Powerpoint presentation and forget to save it on your hard drive or any non-volatile storage. Then, you would lose all the work if your computer lost power before saving the document.
What Remains in the Memory Dump?
Memory Dump contains memory data snapshots captured by your computer at a specific instance of time. It’s also known as Core Dump or System Dump. It also contains useful forensics data such as the system’s state before a system crash or security compromise incident. Memory dumps contain various RAM data that can clarify the cause and other key details about such incidents.
Best Memory Forensics Tools For Data Analysis
Memory Forensics provides complete details of executed commands or processes, insights into runtime system activity, information about open network connections, and lots more. Let’s have a look at some best Memory Forensics tools available out there.
BlackLight is one of the best and smart Memory Forensics tools out there. It makes analyzing computer volumes and mobile devices super easy. Apart from that, BlackLight also provides details of user actions and reports of memory image analysis.
It efficiently organizes different memory locations to find traces of potentially important user activities. Blacklight analyzes several types of memory files including hibernation files, and pagefile.sys, raw dumps, and crash dumps. It can also perform bulk extraction content searches for various items such as phone numbers, addresses, URLs, etc.
Blacklight comes with a powerful file filter view and it’s way faster than other open-source forensics tools. You can use this tool to analyze data from all four major platforms i.e Android, Windows, iOS, and MacOS X.
