解題步驟
- 看觸發資料包。
- 明顯
m
是經過特殊處理的,需要知道它的加密邏輯。看Initiator
模組的window.request
。
m
和t
的賦值就在上面,打斷點。先分析t
。
r.t = p_s = Date[e(496)](new Date)[e(517)]()
將其中跟e
相關的進行還原後,r.t = p_s = Date["parse"](new Date)["toString"]()
,就是一個簡單的獲取時間戳。- 分析
m
變數的生成。
r.m = n[e(528)](btoa, p_s)
,還原後為r.m = n["WcFTW"](btoa, p_s)
。
看下n["WcFTW"]
是什麼,就是把第二個引數叫給第一個引數執行。
簡化一下就是r.m = btoa(p_s)
,p_s
就是時間戳,關鍵就是btoa
函式,定位一下。
一長串,直接開始摳程式碼。
執行報錯,提示function btoa(e) { var t = u , r = {}; r.TGmSp = t(244) + "ARACTER_ERR", r[t(238)] = t(224) + t(250) + "/", r[t(205)] = "^([^ ]+( +" + t(230) + t(259), r.aYkvo = function (e) { return e() } , r[t(254)] = function (e, t) { return e % t } , r.evetF = function (e, t) { return e >> t } , r.GfTek = t(196), r[t(260)] = function (e, t) { return e << t } , r[t(229)] = function (e, t) { return e | t } , r[t(242)] = function (e, t) { return e << t } , r[t(228)] = function (e, t) { return e & t } , r[t(207)] = function (e, t) { return e << t } , r[t(202)] = function (e, t) { return e & t } , r.jdwcO = function (e, t) { return e === t } , r.kPdGe = t(231), r[t(195)] = t(213), r[t(201)] = function (e, t) { return e & t } , r[t(206)] = function (e, t) { return e == t } , r[t(219)] = function (e, t) { return e + t } , r[t(220)] = function (e, t) { return e(t) } ; var i = r; if (/([^\u0000-\u00ff])/.test(e)) throw new Error(i.TGmSp); for (var o, a, s, l = 0, c = []; l < e[t(261)];) { switch (a = e[t(237)](l), s = i.kukBH(l, 6)) { case 0: delete window, delete document, c[t(246)](f[t(245)](i[t(212)](a, 2))); break; case 1: try { "WhHMm" === i[t(198)] || n.g && c[t(246)](f[t(245)](i.pHtmC(2 & o, 3) | i.evetF(a, 4))) } catch (e) { c[t(246)](f[t(245)](i[t(229)](i.cVCcp(3 & o, 4), a >> 4))) } break; case 2: c[t(246)](f[t(245)](i[t(229)](i[t(242)](15 & o, 2), i.evetF(a, 6)))), c[t(246)](f[t(245)](i[t(228)](a, 63))); break; case 3: c[t(246)](f[t(245)](i[t(212)](a, 3))); break; case 4: c.push(f[t(245)](i[t(229)](i[t(207)](i.OWUOc(o, 4), 6), i[t(212)](a, 6)))); break; case 5: c[t(246)](f[t(245)](i[t(229)](i[t(207)](i[t(202)](o, 15), 4), a >> 8))), c.push(f.charAt(i[t(202)](a, 63))) } o = a, l++ } return 0 == s ? i[t(226)](i[t(241)], i[t(195)]) || (c[t(246)](f[t(245)](i[t(201)](o, 3) << 4)), c.push("FM")) : i.eMnqD(s, 1) && (c[t(246)](f[t(245)]((15 & o) << 2)), c[t(246)]("K")), i[t(219)](i.aQCDK(d(15), window.md5(c[t(234)](""))), i[t(220)](d, 10)) } let p_s = Date["parse"](new Date)["toString"](); console.log(btoa(p_s));
u
未定義。
找到u
的定位處,補上程式碼。
再次執行,提示_0x34e7
未定義。
再去找,補全程式碼。
再次執行,提示我們i.eMnqD
不是一個方法。
在頁面輸出一下,是一個判斷變數是否相等的函式。
在我們自己的程式碼裡輸出一下,發現i.eMnqD
未定義。
往上看到i
等於r
,看來是r
變數出了問題。
輸出一下r
。
發現頁面的r
和我們得到的r
的值不一樣,r
的賦值跟t
相關也就是u
函式相關。
隨便輸出一個t(244)
,我們自己得到的也跟頁面不一致。
看來是跟_0x34e7
有關係了,再輸出一下_0x34e7
。
發現順序完全不一致,看來根源就在_0x34e7
這裡,將其重新賦值為頁面輸出的值,再執行,提示f
未定義。
去找f
的定義,直接在程式碼中加上f
的值即可。
再執行,提示d
未定義。
再去找,直接新增上關於d
的程式碼。
再執行,提示window
未定義。
這個問題,直接關注window.md5(c[t(234)](""))
即可,儘量不要有window
。c[t(234)
的值為join
函式。
關注window.md5
的值,找其定義。
補全程式碼,再次執行,儘量將window.md5
換一個名字,我這裡換成了md5
。再執行,提示n
未定義。
找定義,補全。
再執行,提示_0x4c28
未定義。
直接在控制檯輸出,補全。
再次執行,終於得到結果了。
- 開始寫程式碼爬取頁面資料了。

- 嘗試了多次,發現還是報這個問題。經過多次debug,終於發現了問題。
頁面中的n.g
是有值的,不會進入catch
語句。
而程式碼中n.g
是未定義的,導致我們的程式碼會進入catch語句報錯
所以我們這裡直接將n.g
改為true即可,再次執行就可獲得頁面上的數字了。
- 編寫完整程式碼獲取所有頁面數字之和。
