Timemachine is a tool that constructs a Docker image of a Debian base system at any date in the past. For example, if you want to study the glibc bug (CVE-2015-7547), you can't simulate the attack by pulling a Docker image and run the exploit because most distros have been patched by now. Using timemachine, you can roll back to any date in the past, where the glibc library has not been patched and run a corresponding Docker image for experiments. Timemachine uses Debian snapshot repository to make sure you can install a specific package version and its corresponding dependencies. Timemachine is a part of a security testbed that we are developing. We have created container images of recent attacks in our repo, e.g., https://github.com/CSLDepend/itestbed/tree/master/repo/mitm/CVE-2015-7547 https://github.com/CSLDepend/itestbed/tree/master/repo/mitm/... If anyone is interested in developing such testbed for reproducible security experiments, let me know @pmcao
