Chain of CustodyIn digital forensics, the chain of custody is a process that documents the handling and transfer of evidence from the moment it is collected until it is presented in court or stored securely. Maintaining a clear, documented chain of custody is crucial to preserving the integrity and admissibility of evidence, ensuring it has not been tampered with or altered.Chain of CustodyDefin..

Anti ForensicsIn anti-forensics, malware developers use various techniques to conceal malicious activities and make it harder for investigators to detect or analyze the malware. Two primary methods include hiding techniques and timestomping.1. How Malware Tries to HideMalware employs several methods to evade detection and avoid forensic scrutiny, making it harder for investigators to detect its ..

Mobile ForensicsMobile forensics focuses on retrieving and analyzing data from mobile devices like smartphones and tablets. Unique characteristics, such as operating systems and data storage methods, distinguish mobile forensics from traditional computer forensics. Here’s an overview of key concepts in mobile forensics, including jailbreaking, differences between mobile and computer forensics, a..

Memory ForensicsIn memory forensics, investigators analyze a computer’s volatile memory (RAM) to uncover running processes, active connections, malware, and other live activity that might be lost once the system is turned off. Here’s a look at key concepts in memory forensics, from acquisition techniques to tools.Memory AcquisitionPurpose: Acquiring memory (RAM) data involves creating a snapshot..

Disk ForensicsDisk ImagingDefinition: Disk imaging is the process of creating an exact, bit-by-bit copy of a storage device (like a hard drive or SSD) to capture all data, including hidden, deleted, and residual data in unallocated space.Importance: Imaging preserves the original evidence while enabling forensic analysis on the copy, maintaining the integrity of the original data.Best Practice: ..

Network ForensicsIn network forensics, understanding the data flow, connections, and interactions within a network is essential. Here’s an overview of important network forensics components like DNS logs, passive DNS, NetFlow, and sampling rate.DNS Logs / Passive DNSDNS LogsPurpose: DNS logs capture details about DNS queries and responses, helping trace domain name resolutions back to specific t..

Evidence Volatility (network vs memory vs disk)Evidence volatility in digital forensics refers to how quickly certain types of evidence can be lost or altered. Understanding evidence volatility is crucial because it helps prioritize what to capture first during an investigation. Here’s a breakdown of volatility in the context of network, memory, and disk evidence:Network EvidenceVolatility: High..
