Chapter 19 RECOVERING DIGITAL EVIDENCE from LINUX SYSTEMS
Chapter 19 RECOVERING DIGITAL EVIDENCE FROM LINUX SYSTEMS Philip Craiger Abstract As Linux-kernel-based operating systems proliferate there will be an in evitable increase in Linux systems that law enforcement agents must process in criminal investigations. The skills and expertise required to recover evidence from Microsoft-Windows-based systems do not neces sarily translate to Linux systems. This paper discusses digital forensic procedures for recovering evidence from Linux systems. In particular, it presents methods for identifying and recovering deleted files from disk and volatile memory, identifying notable and Trojan files, finding hidden files, and finding files with renamed extensions. All the procedures are accomplished using Linux command line utilities and require no special or commercial tools. Keywords: Digital evidence, Linux system forensics !• Introduction Linux systems will be increasingly encountered at crime scenes as Linux increases in popularity, particularly as the OS of choice for servers. The skills and expertise required to recover evidence from a Microsoft- Windows-based system, however, do not necessarily translate to the same tasks on a Linux system. For instance, the Microsoft NTFS, FAT, and Linux EXT2/3 file systems work differently enough that under standing one tells httle about how the other functions. In this paper we demonstrate digital forensics procedures for Linux systems using Linux command line utilities. The ability to gather evidence from a running system is particularly important as evidence in RAM may be lost if a forensics first responder does not prioritize the collection of live evidence. The forensic procedures discussed include methods for identifying and recovering deleted files from RAM and magnetic media, identifying no- 234 ADVANCES IN DIGITAL FORENSICS tables files and Trojans, and finding hidden files and renamed files (files with renamed extensions. -
