The document discusses anti-forensic rootkits and techniques that can manipulate digital evidence collected through live forensic imaging. It presents DDefy, a proof-of-concept anti-forensic rootkit that intercepts disk read requests and modifies the data returned to hide sensitive information from live forensic tools. DDefy demonstrates that current live imaging methods are insufficient to guarantee collection of untainted evidence, as they rely on the compromised system to provide the data. Better techniques are needed to directly acquire disk data and confirm it matches the kernel and userland views.

Applying Memory Forensics to Rootkit DetectionIgor Korkin
Volatile memory dump and its analysis is an essential part of digital forensics. Among a number of various software and hardware approaches for memory dumping there are authors who point out that some of these approaches are not resilient to various anti-forensic techniques, and others that require a reboot or are highly platform dependent. New resilient tools have certain disadvantages such as low speed or vulnerability to rootkits which directly manipulate kernel structures e.g. page tables. A new memory forensic system – Malware Analysis System for Hidden Knotty Anomalies (MASHKA) is described in this paper. It is resilient to popular anti-forensic techniques. The system can be used for doing a wide range of memory forensics tasks. This paper describes how to apply the system for research and detection of kernel mode rootkits and also presents analysis of the most popular anti-rootkit tools.

[Defcon] Hardware backdooring is practicalMoabi.com
This presentation will demonstrate that permanent backdooring of hardware is practical. We have built a generic proof of concept malware for the intel architecture, Rakshasa, capable of infecting more than a hundred of different motherboards. The first net effect of Rakshasa is to disable NX permanently and remove SMM related fixes from the BIOS, resulting in permanent lowering of the security of the backdoored computer, even after complete earasing of hard disks and reinstallation of a new operating system. We shall also demonstrate that preexisting work on MBR subvertions such as bootkiting and preboot authentication software bruteforce can be embedded in Rakshasa with little effort. More over, Rakshasa is built on top of free software, including the Coreboot project, meaning that most of its source code is already public. This presentation will take a deep dive into Coreboot and hardware components such as the BIOS, CMOS and PIC embedded on the motherboard, before detailing the inner workings of Rakshasa and demo its capabilities. It is hoped to raise awareness of the security community regarding the dangers associated with non open source firmwares shipped with any computer and question their integrity. This shall also result in upgrading the best practices for forensics and post intrusion analysis by including the afore mentioned firmwares as part of their scope of work.
The presentation is all about computer forensics. the process , the tools and its features and some example scenarios.. It will give you a great insight into the computer forensics
Chapter 8 Common Forensic ToolsOverviewIn this chapter, youl.docxchristinemaritza
Chapter 8: Common Forensic Tools
Overview
In this chapter, you'll learn more about:
· Explore disk imaging tools, forensic software tool sets, and miscellaneous software tools
· Understand computer forensic hardware
· Assemble your forensic tool kit
The first steps in any investigation nearly always involve old-fashioned detective work. As a forensic investigator, you need to observe and record your observations first. Once you start examining media contents, you'll need some tools to help you find and make sense of stored data.
Forensic investigators and computer examiners need several different types of tools to identify and acquire computer evidence. Some evidence is hidden from the casual observer and requires specialized tools to find and access. In this chapter, we'll examine a sampling of some common and popular tools available to carry out computer forensic tasks.
Disk Imaging and Validation Tools
After identifying the physical media that they suspect contains evidence, forensic investigators must make sure media is preserved before any further steps are taken. Preserving the media is necessary to provide assurance the evidence acquired is valid.
Chapter 3, "Computer Evidence," and Chapter 4, "Common Tasks," both emphasize the importance of copying all media first and then analyzing the copy. It's usually best to create an exact image of the media and verify that it matches the original before continuing the investigation. It's rare to examine the original evidence for any investigation that might end up in court. For other types of investigations, however, forensic investigators might perform a targeted examination on the original evidence. For example, assume the job is to examine a user's home folder on a server for suspected inappropriate material. It might be impossible or extremely difficult to create a mirror image of the disk drive, but the disk can be scanned for existing or deleted files while it is in use. Although examining media while in use might not always be the best practice, informal investigations use this technique frequently.
To Copy or Not to Copy?
Whenever possible, create a duplicate of the original evidence, verify the copy, and then examine the copy. Always invest the time and effort to copy original media for any investigation that might end up in a court of law. If you are sure your investigation will not end up in court, you might decide to analyze the original evidence directly. This is possible and desirable in cases where copying media would cause service interruptions.
Your choice of tools to use depends on several factors, including:
· Operating system(s) supported
Operating system(s) in which the tool runs
File systems the tool supports
· Price
· Functionality
· Personal preference
The following sections list some tools used to create and verify media copies. Some products appear in two places in the chapter. That's because several products play multiple roles. This section lists several products ...

RAM overview
Volatility overview
http://www.bsatroop780.org/skills/images/ComputerMemory.gif
Understanding RAM
• Two main types of RAM
– Static
• Not refreshed
• Is still volatile
– Dynamic
• Modern computers
• Made up of a collection of cells
• Each cell contains a transistor and a capacitor
• Capacitors charge and discharge (1 and zeros)
• Periodically refreshed
RAM logical organization
• Programs run on computers
• Programs are made up of processes
– Processes are a set of resources used when executing an
instance of a program
– Processes do not generally access the physical memory directly
– Each process has a �virtual memory space�
• Allows operating system to stay in control of allocating memory
– Virtual memory space is made up of
• Pages (default size 4K)
• References (used to map virtual address to physical address)
• May also have a reference to data on the disk (Page file) – used to
free up RAM memory
RAM logical organization
! Each process is represented by an EPROCESS Block:
Normal memory
• Each process is represented by an _EPROCESS block.
• Contained within each _EPROCESS block is both a pointer to the next process
(fLink – Forward Link) and a pointer to the previous process (bLink – Back Link).
• When OS is operating, the _EPROCESS blocks and their pointers come
together to resemble a chain, which is known as a doubly-linked list.
• Chain is stored in kernel memory and is updated every time a process is
launched or terminated.
• Windows API walks this list from head to tail when enumerating processes via
Task Manager, for example.
Not so normal
• Hides processes from windows API
• Known as Direct Kernel Object Manipulation (DKOM)
• Involves manipulating the list of _EPROCESS blocks to �unlink� a
given process from the list
• By changing the forward link of process 1 to point to the third process,
and changing the �bLink� of process 3 to point to process 1, the
attacker�s process is no longer part of the list of _EPROCESS blocks.
• Since the Windows API uses this list to enumerate processes, the
malicious process will be hidden from the user but still able to operate
normally.

Automated Live Forensics Analysis for Volatile Data AcquisitionIJERA Editor
The increase in sophisticated attack on computers needs the assistance of Live forensics to uncover the evidence
since traditional forensics methods doesn’t collect volatile data. The volatile data can ease the difficulty towards
investigation in fact it can provide investigator with rich information towards solving a case. Here we are trying
to eliminate the complexity involved in normal process by automating the process of acquisition and analyzing
at the same time providing integrity towards evidence data through python scripting.

iam giving you entire process of forensc duplication;the response.pdfmukhtaransarcloth
iam giving you entire process of forensc duplication;
the response strategy for forensc duplication is
Decision of when to perform a forensic duplication based is based, in part, on existing response
strategy for the instant situation
For example, many organizations have a policy of creating forensic HD duplicates of all PCs
used by executives that leave the organization.
Forensic Duplicates as Admissible Evidence;
Existing legal standards define minimum criteria for an item to be admitted into evidence
Collection process usually under scrutiny as well
Federal Rules of Evidence ;
Federal Rules of Evidence (FRE) 1002 state that the item or information presented in court must
be the original.
Exceptions: Definitions and Duplicates
If data are stored by computer or similar device, any printout or other output readable by sight,
shown to reflect the data accurately, is an original. Admissibility of Duplicates
A duplicate is admissible to the same extent as an original unless: • A genuine question is raised
as to the authenticity of the original, or • In the circumstances it would be unfair to admit the
duplicate in lieu of the original
first of all what is forensics duplication
A file that contains every bit of information from the source in a raw bitstream format.
Tools that create forensic duplicates:
1. dd
2. FTK Imager, Access Data
3. Dfcldd, US DOD Computer Forensics Lab version of the dd comand
Qualified Forensic Duplicate?
A file that contains every bit of information from the source, but may be stored in a altered form.
Tools that create qualified forensic duplicate output files:
1. SafeBack
2. EnCase
3. FTK Imager
Restored Image;
A restored image is what you get when you restore a forensic duplicate or a qualified forensic
duplicate to another storage medium.
Mismatched drive geometries can cause problems.
HD Development;
When hard drives grew beyond 512MB, the PC-BIOS needed to be updated (to recognize larger
drives). …software emulated a modern BIOS. Software pushed all of the real data on the drive
down one sector and stored its program and information in sector 2.
The real partition table would be at cylinder 0, head 0, sector2. Safeback, EnCase, FTK Imager,
and dd will create a restored image from the qualified forensic duplicate. EnCase and dd images
may not need to be restored. Treat images as virtual disks, eliminating the need for restoration.
Note, FTK Imager can create images in the EnCase Format
Mirror Image ;
Created from hardware that does at bit for bit copy from one hard drive to another.
Requires two identical hard drives
Doesn’t happen very often.
Tool Requirements: Forensic Duplication ;
Tool must: Create a forensic duplicate or mirror image of the original.
Handle read errors in a robust and graceful manner.
Not make any changes to source medium.
Capable of scientific and peer review.
Results must be third party repeatable and verifiable.
Legal Issues
Tools used for forensic duplication must pass the legal tests for r.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
