slide2

As we knew, WikiLeaksdumped nearly 250,000 documents covering private United States diplomatic communications on 11/28

  • 之前報告過,WikiLeaks移動到BahnhofAB
  • Now, there have a new terrible.
slide3

Bank of America says it will no longer process transactions for the website WikiLeaks.

  • It joins financial institutions including MasterCard and PayPal that have stopped handling payments for the site.
  • 因此支持WikiLeaks的組織Anonymous近來不斷招兵買馬以執行報復行動
    • keep the Internet free and open for everyone
    • The Internet has gone to war.
slide4

雙方互相DoS:

    • 反對WikiLeaks → 對WikiLeaks網站發起DDoS
    • 支持WikiLeaks→ 對反對WikiLeaks的網站發起DDoS
  • Anonymous has targeted mainly companies which have decided for whatever reason not to deal with WikiLeaks.
  • Some of the main targets involve Amazon, MasterCard, Visa and PayPal.
  • Anonymous要求那些自願參與DoS的使用者下載合法的LOIC開放源碼工具
slide5

LOIC(Low Orbit Ion Cannon),

    • 主要功能進行網路應用程式的強度測試,以讓開發人員檢視程式的負載能力
    • 同時也能被用來進行惡意的DoS。
  • 使用者透過LOIC可連結發號施令的IRC伺服器,並由該伺服器決定共同「測試」(或攻擊)的目標
slide7

The group used Twitter and IRC to seek supporters, referring them to its website, where they could download the software that turns a Windows or Mac PC into a weapon against the MasterCard site.

  • Twitter 不斷地對於釋放訊息的帳號作停權處分
slide8

雙方有成功嗎?

    • 流量太小(未達10Gbps)
    • 未採用精細的應用程式層級攻擊
  • 前兩級的ISP業者或大型的內容/代管供應商都能夠從容應付
  • For Anonymous
    • 鎖定網頁,非重要後端架構
    • Amazon的失敗,使自願者逐漸放棄
slide11
OLIC下載分析

2.5G/day

攻擊Amazon

失敗,因為資源太少

slide12

Finish?

    • Not,yet
  • 7成是來自於LOIC程式及網路版的JS-LOIC,每個志願者每秒會傳送數十個要求到指定的攻擊網站上,其中,網路版大概只有100行的Javascript程式,功能極少,桌面版複雜一些,能夠受IRC指令控制或隨機轉換攻擊網站。
  • Anonymous支持者近來有釋出另外兩項更複雜的流量癱瘓工具─HOIC及GOIC
