The Incident Response edition of Second Look®: Linux Memory Forensics is designed for use by investigators who need quick, easy, and effective Linux memory acquisition and analysis capabilities.
Second Look® preserves the volatile system state, capturing evidence and information that does not exist on disk and may otherwise be lost as an investigation proceeds. A command-line script allows for acquisition of memory from running systems without introducing any additional software. A memory access driver is provided for use on systems without a native interface to physical memory.
Second Look® interprets live system memory or captured memory images, detecting and reverse engineering malware, including stealthy kernel rootkits and backdoors. A kernel integrity verification approach is utilized to compare the Linux kernel in memory with a reference kernel. Pikewerks provides thousands of reference kernels derived from original distribution kernel packages, and a script for creating reference kernels for other systems, such as those running custom kernels.
Second Look® also applies an integrity verification approach for the analysis of each process in memory. This enables it to detect unauthorized applications as well as stealthy user-level malware.
Second Look® is regularly updated to support analysis of the latest kernels and the most commonly used Linux distributions. The following are its capabilities as of April 2012:
- Supported target kernels: 2.6.x, 3.x up to 3.2
- Supported target architectures: x86 32- and 64-bit
- Supported target distributions: Debian 4-6, RHEL/CentOS 4-6, Ubuntu 4.10-12.04, and more!
