🧂 前言
今天想要介紹 psxview 這個plugin,有時候惡意程式不會出現在pslist或者pstree上,因此會需要使用psxview 幫我們進行比對,找出可疑進程
🍘 仙貝工具
Volatility
下載連結:
Volatility 2 : https://github.com/volatilityfoundation/volatility
Volatility 3 : https://github.com/volatilityfoundation/volatility3
經典的記憶體分析工具,利用指令可以分析 memory dump 中的關鍵訊息,像是進程、網路連線、檔案……等等。
基本的操作這邊推薦可以直接上網查有人整理好的指令doc
而Volatility分為2與3版,差別就是一個是要使用 python2 執行,另一個是用 python3 執行,並且現在Volatility 2 已經沒有在維護了,但是一些 Plugin 的完整度在目前為止還是比 Volatility 3 還要高並且豐富,所以有些人還是會比較會偏向使用 Volatility 2
什麼是pslist/pstree
對沒錯,講了六天的記憶體鑑識,現在才要談什麼是pslist/pstree
pslist/pstree 可以幫助我們去查看這台電腦跑了什麼process,他們分析的方式是會根據Symbol Table 找到Windows Kernel的 PsActiveProcessHead 的位址,然後從那個鏈表開始沿 ActiveProcessLinks 指標逐一讀出 EPROCESS 結構並解析必要欄位,如:ImageFileName、UniqueProcessId、CreateTime、ExitTime 等

另外的pstree 以 pslist 的結果為基礎,轉成父子樹狀。
那如果參考 https://ithelp.ithome.com.tw/m/articles/10321120 或者 https://ithelp.ithome.com.tw/articles/10335699 的其中一個方式, 可以發現其實惡意程式是可以去將process 隱藏起來的,並且讓pslist 與 pstree 無法偵測,因此我們可以使用 psscan 嘗試去偵測
什麼是psscan?
首先要說明,Windows kernel 在為許多核心物件(例如 EPROCESS、ETHREAD、FILE_OBJECT)分配記憶體時,會在 _POOL_HEADER 中放置一個 4-byte 的 pool tag,用來標示該分配的用途或來源。
psscan是一個使用 pool-tag scanning 的掃描器:它會在 memory dump 中搜尋_POOL_HEADER 與 pool tag,並且對找到的候選區塊做結構一致性檢查(例如欄位範圍、指標是否指向可讀記憶體、ProcessName 是否可讀等),來判定該區塊是否為一個有效的 EPROCESS/ETHREAD。因此,即使該程序物件已被從 kernel 的 active list unlink(例如被某些 rootkit 隱藏),只要其 pool 分配尚存在記憶體且尚未被覆寫,psscan 通常可以把它找到。

那我們知道psscan之後我們如果要比對跟pslist 的結果太麻煩了,因此有一個plugin 可以幫助我們進行比對,這個 plugin就是我們今天的主題 psxview
什麼是psxview ?
這個plugin 會將我們剛剛提到的pslist/pstree與psscan以及其他thrdscan、csrss作比較,如果沒有出現在相對應的掃描上就會出現 False, 否則就會出現 true,因此如果有一個process 他在pslist 出現False 但在psscan出現True 那就可以嘗試去分析看看是不是rootkit

結論:
在記憶體鑑識時,有些惡意程式會隱藏自己讓pslist與pstree找不到,因此可以用PsXView 這個Plugin幫助我們去比對是否有可疑的程式。
