If malware has taken root on a system, you need a way to safeguard the evidence. Guymager helps you create verified disk images.
Forensic data backup tools are used in situations in which analysis of the original medium is not advisable because it could cause structural changes. The best way to study a storage medium for evidence of malware or intrusion activity is to make an accurate copy and perform your analysis on the copy. However, you need a way to verify that the duplicate is an accurate copy of the original.
Conventional disk image copy tools usually are not suitable for this type of undertaking because they lack an option for validating the image. On the other end, a high-end, professional forensics distro is sometimes more than you need. In these cases, Guymager [1] disk image tool is an interesting option. Guymager quickly creates images and, at the same time, provides evidence of identical data structures.
Getting Guymager
Guymager is available from the repositories on Debian and Ubuntu and their derivatives. For openSUSE [2] and Fedora [3], you can pick up the packages online. Additionally, a few Live distros like Deft or Kali Linux also contain the tool. For all other systems, your only option is to build from the source code, which you will find on the project web page along with detailed instructions.
