'afick' is a multi-platform file integrity checker. It works by first creating a database that represents a snapshot of the essential parts of your computer system. You then run the script to discover all modifications made since the snapshot was taken (i.e. files added, changed, or removed). It shows new, deleted and changed files (rights, owner, size, content).
'AntiExploit' scans for well known exploit files. It currently recognizes over 1700 suspicious files, and the database is updated weekly. It is not meant to be a IDS or high-profile security-application, but rather an extension to other security checks. 'aexpl' was developed for a freeshell-server to track script-kiddies.
BleachBit deletes unnecessary files to free valuable disk space, maintain privacy, and remove junk. It removes cache, Internet history, temporary files, cookies, and broken shortcuts. Some common uses include:
  • Free disk space
  • Reduce the size of backups and the time to create them by removing unnecessary files
  • Maintain privacy
  • Improve system performance (by vacuuming your browser's database, for example)
  • Prepare whole disk images for compression (common for "ghost" backups and virtual machines) by wiping free disk space
Add security to your desktop by automatically locking and unlocking the screen when you and your phone leave/enter the desk. Think of a proximity detector for your mobile phone or other device via bluetooth.
Bunny the Fuzzer
* " IMPORTANT: This project (Bunny the Fuzzer) is superseded by American Fuzzy Lop " A closed loop, high-performance, general purpose protocol-blind fuzzer for C programs. Uses compiler-level integration to seamlessly inject precise and reliable instrumentation hooks into the traced program. These hooks enable the fuzzer to receive real-time feedback on changes to the function call path, call parameters, and return values in response to variations in input data. This architecture makes it possible to significantly improve the coverage of the testing process without a noticeable performance impact usually associated with other attempts to peek into run-time internals. Bunny is currently known to support GNU/Linux, FreeBSD, OpenBSD, and Cygwin on IA32 and IA64 systems.
cage is a replacement for the chroot(8) utility. Like chroot, cage changes its root directory to the one specified and then executes your application. Before execing, however, cage drops all privileges that would let the program escape its jail.
'changedfiles' is a framework for filesystem replication, security monitoring, and/or automatic file transformations--anything where you'd poll files or directories and then do something to them or send them somewhere else (or both). The difference is, the kernel tells you when they change, instead of you having to poll. It is also an easy real time FTP push mirror to one or multiple sites. 'changedfiles' has a kernel module (works with Linux kernel version 2.4) which reports to a device whenever a file on the filesystem changes, and a daemon which runs in user space and can be configured to do almost anything when a change to a file matching one of the patterns it looks for is reported.
chkrootkit is a tool to locally check for signs of a rootkit. It contains programs to check for modified system binaries, signs of LKM trojans and more. It currently detects 60 rootkits, worms and LKMs.
Chroot safe
'chroot_safe' is a alternative method for chrooting dynamically linked applications. It delays the chrooting until after dynamic linking has completed, so you don't need to have a copy of the binary or libraries within the chroot. This simplifies the process of chrooting an application, as you often do not need any files besides the data files within the chroot. In addition to chrooting the application, 'chroot_safe' also drops root privileges before letting the application start.
