🐽 🈴 🚙 Goでのフラッシュゲームのリバースエンジニアリングとボットの作成 😓 🆚 🏣

この記事では、フラッシュアプリケーションを逆コンパイルし、リクエスト署名アルゴリズムをゲームサーバーに抽出する方法を説明します。そして、この情報に基づいて、 Goでゲームボットを作成する方法を説明します。

それはすべて、Androidスマートフォンで遊ぶための戦略を探していたという事実から始まりました。「玉座ラッシュ」と呼ばれる良いゲームを見つけました。その後、ブラウザクライアントもあることが判明しました。これにより、いくつかのアクションがより便利になります。それでも、ゲームプレイには明らかに自動化が必要でした。後で説明する優れたツールJPEXS Free Flash Decompilerを使用しました。

githubのプロジェクトのソースコード。

そのため、タスクはネイティブクライアントの作業をエミュレートすることです。

Firebug'om監視通信フラッシュアプリケーション

これはX-Auth-Signatureの問題です。どこで入手できるかわかりませんでした。明らかに、これは何らかのハッシュです。しかし、何と何が不明です。「FFDec」はこれを助けてくれました。 Javaで作成されたオープンソースプログラムはLinuxで実行されます。この仕事に最適です。

htmlコードは、どのファイルがロードされているかを示しています。

 <object id="flash-app" width="100%" height="100%" data="https://epicwar-a.akamaihd.net/facebook/static/assets/Start.swf?v=13" type="application/x-shockwave-flash">

しかし、実際には、これは必要なものではありません。 flashvarsを探します。そこで「preloader = https％3A％2F％2Fepicwar-a.akamaihd.net％2Ffacebook％2Fv042％2FFbLoader.swf％3Fv％3D2」。しかし、これはそうではありません。そして、必要なコードは、私がそれをどのように理解したかを正確に覚えていません。実際、 https：//epicwar-a.akamaihd.net/facebook/v042/EpicWar.swfです。

逆コンパイル中です。

プログラムウィンドウ

実際、エクスポートがあります。

これが逆コンパイルされたコードです

 protected function createHeaders(param1:RpcEntryBase) : Object { var _loc5_:String = null; var _loc2_:String = SocialAdapter.instance.flashVars["session_key"]; var _loc3_:Object = { "Content-Type":"application/json; charset=UTF-8", "X-Request-Id":++this.unionRequestID, "X-Auth-Network-Ident":Env.NETWORK, "X-Auth-Application-Id":SocialAdapter.instance.app_id, "X-Auth-User-Id":SocialAdapter.instance.getPlayer().id, "X-Auth-Session-Id":Env.sessionKey }; if(_loc2_ != null) { _loc3_["X-Auth-Session-Key"] = _loc2_; } var _loc4_:Object = param1.headers; if(_loc4_ != null) { for(_loc5_ in _loc4_) { _loc3_[_loc5_] = _loc4_[_loc5_]; } } return _loc3_; } protected function createAuthSignature(param1:Object, param2:RpcEntryBase) : ByteArray { var _loc5_:ByteArray = null; var _loc3_:Object = param2.request.getFormattedData(); var _loc4_:ByteArray = new ByteArray(); _loc4_.writeUTFBytes(param1["X-Request-Id"]); _loc4_.writeUTFBytes(":"); _loc4_.writeUTFBytes(SocialAdapter.instance.authentication_key); _loc4_.writeUTFBytes(":"); _loc4_.writeUTFBytes(param1["X-Auth-Session-Id"]); _loc4_.writeUTFBytes(":"); if(_loc3_ is ByteArray) { _loc5_ = _loc3_ as ByteArray; _loc5_.position = 0; _loc4_.writeBytes(_loc5_,0,_loc5_.length); } else if(_loc3_ is String) { _loc4_.writeUTFBytes(_loc3_ as String); } _loc4_.writeUTFBytes(":"); _loc4_.writeUTFBytes(this.createFingerprint(param1)); return _loc4_; } private function createFingerprint(param1:Object) : String { var _loc4_:String = null; var _loc5_:* = 0; var _loc6_:* = 0; var _loc7_:String = null; var _loc2_:Array = []; var _loc3_:* = ""; for(_loc4_ in param1) { if(_loc4_.indexOf("X-Env") != -1) { _loc7_ = _loc4_.substr(6); _loc2_.push( { "key":_loc7_.toUpperCase(), "value":param1[_loc4_] }); } } _loc2_.sortOn("key"); _loc5_ = _loc2_.length; _loc6_ = 0; while(_loc6_ < _loc5_) { _loc3_ = _loc3_ + (_loc2_[_loc6_].key + "=" + _loc2_[_loc6_].value); _loc6_++; } return _loc3_; } protected function addHeaders(param1:URLRequest, param2:RpcEntryBase) : void { var _loc4_:String = null; var _loc3_:Object = this.createHeaders(param2); var _loc5_:ByteArray = this.createAuthSignature(_loc3_,param2); _loc3_["X-Auth-Signature"] = MD5.hashBytes(_loc5_); for(_loc4_ in _loc3_) { param1.requestHeaders.push(new URLRequestHeader(_loc4_,_loc3_[_loc4_].toString())); } }

すべてがシンプルです。通常のmd5。以下はGoのこのコードです。

ネットワーク

 package network import ( "net/http" "strings" "bytes" "crypto/md5" "io" "encoding/hex" "strconv" "io/ioutil" "log" ) const SERVER_URL = "https://epicwar-facebook.progrestar.net/rpc/" const APP_ID = "1424411677784893" const AUTH_KEY = "6514a97ae525f196b8060337380e0cbb" const NETWORK = "facebook" var _unionRequestID int var _uid string var _sid string func createFingerprint(headers map[string]string) string { var fingerprint bytes.Buffer preparedHeaders := []Pair{} for header, _ := range headers{ if(strings.Index(header, "X-Env") != -1){ preparedHeaders = append(preparedHeaders, Pair{ key : strings.ToUpper(header[6:len(header)]), value : headers[header]}) } } sortByKey(preparedHeaders) count := len(preparedHeaders); i := 0; for i < count { fingerprint.WriteString(preparedHeaders[i].key) fingerprint.WriteString("=") fingerprint.WriteString(preparedHeaders[i].value) i++; } res := fingerprint.String() return res } func createAuthSignature (headers map[string]string, postData string) string { h := md5.New() io.WriteString(h, headers["X-Request-Id"]) io.WriteString(h, ":") io.WriteString(h, AUTH_KEY); io.WriteString(h, ":"); io.WriteString(h, headers["X-Auth-Session-Id"]); io.WriteString(h, ":"); io.WriteString(h, postData); io.WriteString(h, ":"); io.WriteString(h, createFingerprint(headers)); return hex.EncodeToString(h.Sum(nil)) } func createHeaders() (map[string]string) { _unionRequestID = _unionRequestID + 1 headers := map[string]string{ "X-Request-Id":strconv.Itoa(_unionRequestID), "X-Auth-Network-Ident":NETWORK, "X-Auth-Application-Id":APP_ID, "X-Auth-User-Id":_uid, "X-Auth-Session-Id":_sid, "X-Env-Library-Version": "0"} return headers } func addHeaders(req *http.Request, postData string) { headers := createHeaders(); headers["X-Auth-Signature"] = createAuthSignature(headers, postData); for index, header := range headers { req.Header.Add(index, header) } } func Post(postData []byte) []byte { client := &http.Client{} req, err := http.NewRequest("POST", SERVER_URL, bytes.NewReader(postData)) addHeaders(req, string(postData)) resp, err := client.Do(req) defer resp.Body.Close() body, err := ioutil.ReadAll(resp.Body) if(err != nil){ log.Fatal(err) } return body } func Init(Uid string, Sid string) { _unionRequestID = 0 _uid = Uid _sid = Sid }

どうやら、私は余分な見出しを送信しません。アクションスクリプトコードでは、RpcClientBaseクラスはRpcClientクラスによって「com.progrestar.game.server.rpc」から継承され、さらにヘッダーが追加されます。たとえば、そこから取った「X-Env-Library-Version」。彼なしでは機能しません。

リバースエンジニアリングの一部は終了しました。ボットのロジックの一部になりました。ネイティブクライアントでプレイする機会を残しました。これを行うには、ブラウザーでhttp：// localhost：8080 / originalに移動します。

一部のフラッシュバーは必要ないと思いますが、すべてのフラッシュバーを残しました。

通信プロトコルは非常に簡単です。 POSTリクエストと1つのURLのみ。 Grepolisの場合のように、GET / POSTリクエストとパラメーターは豊富ではありません。

次に、ボットはゲームカードを個別に受け取り、 http：// localhost：8080 / botで表示できます。これは、美と等尺性のない単なる地図です。しかし、一方で、どのような建物がどこにあるかがはっきりと見えるため、敵が攻撃を仕掛けることができる都市の真ん中に空いている場所が出現する可能性が低くなります。私はこれをよく自分でやった。また、ネイティブクライアントでは、角度を変更できない不快な等角投影は必ずしも便利ではありません。

リソースを収集することから始めます。とても簡単です。可能な場合はリソースを収集し、スリープ状態になる別のゴルーチンが作成されます。答えは、建物とリソース、いわゆる状態にあります。

リソースコレクターのソースコードは次のとおりです。

 func processCollectRequest(player *Player, resp *Response){ for _, result := range resp.Results { if(result.Ident == "group_1_body"){ parseResources(player, result.Result["resource"].([]interface{})) parseBuildings(player, result.Result["building"].([]interface{})) } } } func collectFood(player *Player) *Response{ var resp *Response for _, building := range player.Buildings { if(building.TypeId == MILL_ID){ resp = decodeJson(network.Post(collectResource(building.Id))) } } return resp } func collectGold(player *Player) *Response{ var resp *Response for _, building := range player.Buildings { if(building.TypeId == MINE_ID){ resp = decodeJson(network.Post(collectResource(building.Id))) } } return resp } func resourcesCollector(playerChan chan Player) { var resp *Response var playerStruct Player var player *Player resp = nil playerStruct = <- playerChan player = &playerStruct if(player.FoodCapacity > player.Food){ log.Print("Collect Food") resp = collectFood(player) } if(player.GoldCapacity > player.Gold){ log.Print("Collect Gold") resp = collectGold(player) } if(resp != nil){ processCollectRequest(player, resp) resp = nil } playerChan <- playerStruct time.Sleep(time.Minute * 10) go resourcesCollector(playerChan) }

多くの建物があり、個々のブロックをクリックするのは非常に不便であるため、壁の建物のみを自動改善しました。それに応じて、同じ状態になります。

また、参照によって構造をゴルーチンに単純に転送することもできます。しかし、これを行うと、ガベージコレクターはしばらくしてメモリをクリアし、nullPointer例外をスローしました。したがって、チャネルを使用します。

ボットのクライアント部分も代表します。最も困難なことは、建物がない場所を最適に表示することでしたが、そこにも着陸を落とすことはできません。残りは非常に簡単です。
