    UACMe

    UACMe

    Defeating Windows user account control

    Run executable from command line, akagi32 [Key] [Param] or akagi64 [Key] [Param]. First parameter is a number of methods to use, second is an optional command (executable file name including full path) to run. The second parameter can be empty - in this case, the program will execute elevated cmd.exe from the system32 folder. Since 3.5.0 version all "fixed" methods are considered obsolete and removed altogether with all supporting code/units. If you still need them. This tool shows ONLY popular UAC bypass method used by malware, and re-implement some of them in a different way improving original concepts. There are different, not yet known to the general public, methods. This tool is not intended for AV tests and not tested to work in aggressive AV environment, if you still plan to use it with installed bloatware AV soft, use it at your own risk.

    xxHash

    xxHash

    Extremely fast non-cryptographic hash algorithm

    xxHash is an extremely fast non-cryptographic hash algorithm, working at RAM speed limit. It is proposed in four flavors (XXH32, XXH64, XXH3_64bits and XXH3_128bits). The latest variant, XXH3, offers improved performance across the board, especially on small data. It successfully completes the SMHasher test suite which evaluates collision, dispersion and randomness qualities of hash functions. Code is highly portable, and hashes are identical across all platforms (little / big endian). Performance on large data is only one part of the picture. Hashing is also very useful in constructions like hash tables and bloom filters. In these use cases, it's frequent to hash a lot of small data (starting at a few bytes). Algorithm's performance can be very different for such scenarios, since parts of the algorithm, such as initialization or finalization, become fixed cost. The impact of branch misprediction also becomes much more present.

    BerserkArch

    BerserkArch

    A bleeding-edge, security-centric Arch-based Linux distribution.

    BerserkArch is a security-focused, performance-tuned Linux operating system (OS) based on Arch Linux, designed for developers, hackers, and technical users. A bleeding-edge, security-centric Arch-based Linux distribution crafted for hackers, developers, and nerds alike. Following the Arch Linux philosophy, it is designed to be highly customizable, allowing users to build their environment with only the components they need, rather than having a lot of pre-installed software like some other security distributions (e.g., Kali Linux). As an Arch-based distribution, it benefits from the rolling release model, providing users with the latest software versions and kernel updates. BerserkArch is a dist "designed to make you powerful" for specific use cases like reverse-engineering binaries and automating exploits, rather than being an easy-to-use distribution for general beginners.

    denuvo

    DENUVO (VMProtect 2.6x) VM research tool

    This is part of the original source code of DENUVO_Profiler, written by 386 Team in 2014-2017 to investigate the first versions of DENUVO (eq VMProtect 2-3), when there were no lifters and other modern devirtualisation tools. DENUVO_Profiler is a subsequent development of the SecuROM_Profiler utility - the simplest tool for visualising the operation of a virtual machine and effectively controlling the data it uses in the byte-code tape (p-code). DENUVO_Profiler also hunts for Electronic Arts (Origin) licence containers on the current user's machine and can extract their contents, with including the GameToken. # See also: 80_PA SecuROM keygen

    American Fuzzy Lop

    American Fuzzy Lop

    American fuzzy lop - a security-oriented fuzzer

    AFL (American Fuzzy Lop) is a widely used graybox fuzzer that discovers bugs by mutating inputs and steering execution using lightweight instrumentation. Instead of random mutations alone, it uses coverage feedback to evolve input corpora, pushing programs into deeper and more interesting code paths. Its workflow emphasizes quick start: point it at a target binary with compile-time instrumentation (or use QEMU-based mode when recompilation isn’t possible), seed it with a small corpus, and let it iterate. AFL is known for finding serious security issues in complex software due to its corpus minimization, queue management, and deterministic mutation stages that balance breadth and depth. It provides crash triage helpers and test case minimization so developers can reproduce and fix issues quickly. The design deliberately optimizes for robustness and speed on commodity hardware, which helped it become a standard part of many security testing pipelines.

    OMEN

    OMEN

    OMEN: Ordered Markov ENumerator - Password Guesser

    OMEN is a Markov model-based password guesser written in C. It generates password candidates according to their occurrence probabilities, i.e., it outputs most likely passwords first. OMEN significantly improves guessing speed over existing proposals. If you are interested in the details on how OMEN improves on existing Markov model-based password guessing approaches, please refer to OMEN: Faster Password Guessing Using an Ordered Markov Enumerator. OMEN consists of two separate program modules: createNG and enumNG. createNG calculates n-gram probabilities based on a given list of passwords and stores them on the hard disk. Based on these probabilities enumNG enumerates new passwords in the correct order (descending). Before one can generate any passwords, the n-gram probabilities have to be estimated using createNG. To calculate the probabilities using the default settings, createNG must be called giving a path to a password list that should be trained.

    Tempesta FW

    Tempesta FW

    All-in-one solution for high performance web content delivery

    Tempesta FW is an all-in-one open-source solution for high performance web content delivery and advanced protection against DDoS and web attacks. This is a drop-in-replacement for the whole web server frontend infrastructure: an HTTPS load balancer, a web accelerator, a DDoS mitigation system, and a web application firewall (WAF). Tempesta FW is the first and only hybrid of a Web accelerator and a multi-layer firewall. This unique architecture provides seamless integration with the Linux iptables or nftables. Tempesta FW services up to 1.8M HTTP requests per second on the cheapest hardware, which is x3 faster than Nginx or HAProxy. Tempesta TLS is about 40-80% faster than Nginx/OpenSSL and provides up to x4 lower latency.
