Dirty Frag
Universal Linux LPE
Dirty Frag is a low-level networking and packet manipulation project focused on fragmentation-based techniques for bypassing filters, firewalls, or DPI systems during network communication. The project explores how fragmented packets can be crafted and transmitted to alter how traffic is interpreted by inspection systems or network devices. It is primarily aimed at networking enthusiasts, security researchers, and developers experimenting with packet-level behavior and protocol edge cases. dirtyfrag emphasizes lightweight execution and direct control over fragmentation workflows rather than providing a full networking suite. ... -

Sandboxie
Sandboxie Plus & Classic
Sandboxie (and its enhanced fork Sandboxie Plus) is an open-source sandboxing tool for Windows NT-based systems. It creates isolated virtual environments in which applications can run safely without permanently modifying the system, ideal for testing untrusted software. Sandboxie Classic has the old no longer developed MFC-based UI, hence it lacks native interface support for Plus features. Although some of the missing features can be configured manually in the Sandboxie.ini configuration... -

LibNetBlock - A Network Blocking Library
A library for blocking access to network on-the-fly
LibNetBlock is a library that on-the-fly (by preloading) prevents a program under its control to use the network, to help to keep the user's privacy, prevent data leakage and virus spreading. You can think of LibNetBlock as a simple layer-7 (L7) firewall that simply blocks the network access for the program it controls. There is NO NEED to rebuild your software, because LibNetBlock is a pre-loadable library, meaning you just need to RUN the software with LibNetBlock loaded. LibNetBlock is... -

try
Inspect a command's effects before modifying your live system
...This makes it useful for experimenting with package installation, system changes, and other shell commands where users want a chance to review the outcome first. The project is careful not to position itself as a full security sandbox, since trusted commands can still make network calls and the tool is presented as a prototype rather than a complete isolation boundary. It supports multiple Linux distributions and can fall back to mergerfs or unionfs in environments where overlayfs on nested mounts does not work as expected. In practice, -

Honggfuzz
Security oriented software fuzzer
honggfuzz is a general-purpose, high-performance fuzzer that mixes coverage feedback with practical crash triage to uncover memory-safety and logic bugs. It supports multiple fuzzing modes—stdin, file, and networking—so targets can be exercised the same way they run in production. Instrumentation via compiler hooks or hardware/perf counters guides mutations toward previously unseen edges, while persistent mode keeps the target process alive to amortize startup costs. The tool integrates... -
