Using and Extending Kojoney SSH Honeypot
Kojoney (http://kojoney.sourceforge.net/)
is a wonderful low interaction SSH honeypot written in Python.
Honeypots are systems that are set up in a deliberately vulnerable state
in order to capture and observe intruder behaviour. For more
information about honeypots see the excellent HoneyNet Project (http://www.honeynet.org/).
There are many reasons to run a honeypot, but for the purposes of this
discussion we will assume that you want to run a honeypot to observe
post compromise behavior in order to fingerprint patterns. This is
useful because you can use fingerprints to set up alerting or protective
mechanisms that can detect compromise quickly and aid in response. For
instance, running a honeypot you might discover that most attackers,
after compromising an apache web server, attempt to write a file into
the /tmp directory. You can use this information to set up monitoring
of the /tmp directory, and alert administrators whenever apache writes
new files into /tmp. This can tip off systems administrators to a
possible compromise, by alerting them that there is behavior occurring
on their system that typically corresponds to post compromise attacker
behavior.

Supersonic Query Engine
Introduction
Supersonic is an ultra-fast, column oriented query engine library written in C++. It provides a set of data transformation primitives which make heavy use of cache-aware algorithms, SIMD instructions and vectorised execution, allowing it to exploit the capabilities and resources of modern, hyper pipelined CPUs. It is designed to work in a single process.Supersonic is intended to be used as a back-end for various data warehousing projects. The functionalities it provides are:
- speed
- cache consciousness
- instruction pipelining
- SIMD use
- efficient memory allocation
- custom data structures
- reliability
- failure handling
- high test coverage (under development)
- robustness
- support for standard columnar database operations
- a wide range of specialised expressions (including many math, string and date manipulation functionalities)
Scripted : Javascript Editor from vmware
What is Scripted?
Scripted is a fast and lightweight code editor with an initial focus on JavaScript editing. Scripted is a browser based editor and the editor itself is served from a locally running Node.js server instance.What are the key features?
- Fast startup, lightweight.
- Syntax highlighting for JavaScript, HTML and CSS.
- Errors and warnings:
- JSLint is integrated to provide error/warning markers on JavaScript code.
- AMD and CommonJS module resolution: there is basic resolution where unresolved references will be marked as errors.
- Content assist:
- Basic content assist for HTML, CSS
- For JavaScript, content assist is driven by a type inferencing engine which is aware of AMD/CommonJS module dependencies and also uses JSDoc comments to help it understand the code.
- Hovers: hovering over a JavaScript identifier will bring up the inferred type signature.
- Navigation:
- press F8 on an identifier (that the inferencer has recognized) and the editor will navigate to the declaration.
- this also works on module identifiers (e.g. in
define()
clauses)
- Formatting: JSbeautify is integrated
- Sidepanel: alongside the main editor a sidepanel can be opened - currently this can be used to host a second editor.
- Key binding to external command: Key bindings in the editor can invoke external commands (less, mvn, etc)
Many of these are covered in this introductory screencast:
