Damn Vulnerable GraphQL Application is an intentionally vulnerable implementation of Facebook's GraphQL technology, to learn and practice GraphQL Security. DVGA has numerous flaws, such as Injections, Code Executions, Bypasses, Denial of Service, and more. See the full list under the Scenarios section. A public Postman collection is also available to replay solutions to the challenges. DVGA supports Beginner and Expert level game modes, which will change the exploitation difficulty.

...The module exposes directives for enabling audit logging, anomaly scoring, request body buffering limits, and performance tuning to fit high-traffic deployments. Because it’s a native NGINX module, it benefits from NGINX’s event-driven architecture and can be compiled as a dynamic module for flexible packaging. In practice, it provides a portable, policy-driven security layer at the edge without modifying application code.

This is a commandline utility that converts a WAV sound file containing morse code to English text. Pre-built binaries run on OSX, MsWindows, & GNU/linux. It is written in Ada, so can be rebuilt on any platform with an Ada compiler. The input wav file must be monaural, with a 16-bit signed integer encoding, and a sample rate of 8000 Hz. Either sox or audacity can easily transform to this format. The wav file is expected to be international morse code, preferrably clean and properly spaced. ...

GOAD (Gather Open Attack Data) is a security reconnaissance framework for collecting, enriching, and visualizing open-source intelligence (OSINT) around hosts, domains, and certificates. It automates queries to certificate transparency logs, passive DNS, subdomain enumeration, web endpoints, and other public threat feeds. The tool aggregates results into structured formats and can produce interactive graphs to highlight relationships between entities (e.g. domain → IP → cert → ASN). Analysts...

...It includes exercises that explain how malware-like behaviors can be recognized and studied in a controlled lab context. The project also demonstrates how analysis tools can be used to inspect binaries, understand execution behavior, and reason about malicious code. Its main value is giving learners structured practice with real malware-analysis concepts while keeping the content oriented toward research and defense.

...The software generates sufficiently random passwords to allow the same plaintext password to be used multiple times without generating the same output. There's probably no real reason to be developing this, but I wanted to use the NERD code in a new way and practice my C++ skills at the same time.

For over 30 years, password requirements and feedback have largely remained a product of LUDS: counts of lower- and uppercase letters, digits and symbols. LUDS remains ubiquitous despite being a conclusively burdensome and ineffective security practice. zxcvbn is an alternative password strength estimator that is small, fast, and crucially no harder than LUDS to adopt. Using leaked passwords, we compare its estimations to the best of four modern guessing attacks and show it to be accurate and conservative at low magnitudes, suitable for mitigating online attacks. We find 1.5 MB of compressed storage is sufficient to accurately estimate the best-known guessing attacks up to 105 guesses, or 104 and 103 guesses, respectively, given 245 kB and 29 kB. zxcvbn can be adopted with 4 lines of code and downloaded in seconds. ...

Codegroup is a Java application that will allow one to convert binary (or text) computer files in to 5 letter codegroups for transmission over email, landline telephones, radioteletype or Morse Code.
