描述

FOXBORO P0914XA

Stuxnet會根據(jù)目標系統(tǒng)的特點，使用不同的代碼來感染PLC。一個感染的序列包括了許多PLC模塊（代碼模塊和數(shù)據(jù)模塊），用以注入PLC來改變目標PLC的行為。這個威脅包括了三個感染序列。其中兩個非常相似，功能也相同，我們將其命名為序列A和B。第三個序列我們命名為序列C。Stuxnet通過驗證“指紋”來判斷系統(tǒng)是否為計劃攻擊的目標。它會檢查：PLC種類/家族：只有CPU6ES7-417和6ES7-315-2會被感染。系統(tǒng)數(shù)據(jù)模塊：SDB會被解析；根據(jù)他們包含的數(shù)據(jù)，感染進程會選擇A,B或其它感染方式開始行動。當解析SDB時，代碼會搜索這兩個值是否存在–7050hand9500h；然后根據(jù)這兩個數(shù)值的出現(xiàn)次數(shù)，選擇序列A或B中的一種來感染PLC。代碼還會在SDB模塊的50h子集中搜索字節(jié)序2CCB0001,這個字節(jié)序反映了通信處理器CP342-5(用作Profibus-DP)是否存在。而選擇序列C進行感染的條件則由其他因素構(gòu)成。為了不被PLC所檢測到，它至少需要應(yīng)付以下情況：對自己的惡意數(shù)據(jù)模塊的讀請求；對受感染模塊(OB1,OB35,DP_RECV)的讀請求；可能覆蓋Stuxnet自身代碼的寫請求。Stuxnet包含了監(jiān)測和攔截這些請求的代碼，它會修改這些請求以保證Stuxnet的PLC代碼不會被發(fā)現(xiàn)或被破壞。下面列出了幾個Stuxnet用被掛鉤的導(dǎo)出命令來應(yīng)付這些情況的例子：s7blk_read:監(jiān)測讀請求，而后Stuxnet會返回：真實請求的DP_RECV(保存為FV1869)；錯誤信息，如果讀請求會涉及到它的惡意模塊；OB1或OB35的干凈版本的拷貝s7blk_write:監(jiān)測關(guān)于OB1/OB35的寫請求，以保證他們的新版本也會被感染。s7blk_findfirst/s7blk_findnext:這些例程被用于枚舉PLC中的模塊。惡意模塊會被自動跳過。s7blk_delete:監(jiān)測對模塊的“刪除”操作。如上文所述，Stuxnet是一個非常復(fù)雜的威脅，而其中的PLC感染代碼令問題更加難以解決。
