Check Point 2月份網絡威脅指數及Microsoft Exchange Server漏洞

 

全球領先網絡安全解決方案供應商 Check Point® 軟件技術有限公司(納斯達克股票代碼:CHKP)的威脅情報部門 Check Point Research 發布了 2021 年 2 月最新版《全球威脅指數》報告。研究人員報告稱,Trickbot 木馬從 1 月份指數排行榜的第三位首次升上至榜首。

加上,Check Point Research發現有數百次針對​​全球組織所利用漏洞的嘗試與影響 Microsoft Exchange Server 的四個零日漏洞有關。 僅在過去的 72 小時內,CPR 觀察到利用漏洞而進行嘗試的次數便增加了 5 倍以上。

香港2月份主要惡意軟件

以下是香港2月份首10個惡意軟件。至於全球的排名列表,你可於瀏覽。

  1. Emotet 是本月份最活躍的惡意軟件,影響了全球3%的組織,緊隨其後的是 XMRig  Qbot,它們亦影響了全球3%的組織。
  2. Web Server Exposed Git 儲存庫訊息洩露」是本月份最常被利用的漏洞,影響全球 48% 的組織,其次是HTTP 標頭遠程代碼執行 (CVE-2020-13756),影響全球 46% 的組織。MVPower DVR遠端代碼執行」在最常被利用的漏洞排行榜中位列第三,全球影響了45%。
  3. Hiddad 在本月的最普遍流動惡意軟件中位第一,緊隨其後的是 xHelper  FurBall

Check Point 產品威脅情報與研究總監 Maya Horowitz 表示:「犯罪分子將繼續使用現有的威脅手段和工具,Trickbot 是因它的多功能性及以往的攻擊戰果而變得流行。正如我們估計,即便有一個重大的威脅被消除,亦會有很多其他威脅繼續對全球網絡構成高風險,因此組織必須確保採用強大的安全系統來防止其網絡遭到入侵,並將風險降至最低。對所有員工進行全面培訓是非常重要,這樣他們才能夠掌握所需技能,從而準確識別傳播Trickbot 及其他惡意軟件的惡意電子郵件類型。」

繼披露了目前影響 Microsoft Exchange Server 的四個零日漏洞後,Check Point Research (CPR) 公佈了對這些利用漏洞而進行嘗試的最新全球觀察結果。

  • CPR發現有數百次針對全球組織所利用漏洞的嘗試。 僅在過去的 72 小時內,CPR 觀察到利用漏洞而進行嘗試的次數便增加了 5 倍以上。

Trickbot sends information about the infected system and can also download and execute arbitrary modules from a large array of available modules: from a VNC module for remote control, to an SMB module for spreading within a compromised network. Once a machine is infected, the Trickbot gang, the threat actors behind this malware, utilize this wide array of modules not only to steal banking credentials from the target PC, but also for lateral movement and reconnaissance on the targeted organization itself, prior to delivering a company-wide targeted ransomware attack. 3.17% 7.65%
