SafePay 勒索軟體：一種劫持檔案的數位勒索手段

SafePay 勒索軟體的機制

SafePay 勒索軟體是一種數位勒索工具，旨在加密受害者的文件，使其在支付贖金之前無法存取。與其他勒索軟體威脅一樣，它以企業和個人為目標，鎖定關鍵數據並要求付款以恢復。這種特殊的病毒會在被感染的文件名稱後面附加“.safepay”，從而在文件上留下明顯的標記。例如，原來名為“document.pdf”的文件將被重新命名為“document.pdf.safepay”，以表示該文件已被加密。

除了加密檔案之外，SafePay 還會產生一份名為「readme_safepay.txt」的勒索信，向受害者提供如何與攻擊者溝通的說明。報告指出，此次攻擊是由於受害者網路的「安全配置錯誤」而發生的。網路犯罪分子聲稱竊取了敏感資料並威脅說，如果他們得不到滿足他們的要求，他們就會洩露這些資料。

贖金通知的內容如下：

Greetings! Your corporate network was attacked by SafePay team.

Your IT specialists made a number of mistakes in setting up the security of your corporate network, so we were able to spend quite a long period of time in it and compromise you.

It was the misconfiguration of your network that allowed our experts to attack you, so treat this situation as simply as a paid training session for your system administrators.

We’ve spent the time analyzing your data, including all the sensitive and confidential information. As a result, all files of importance have been encrypted and the ones of most interest to us have been stolen and are now stored on a secure server for further exploitation and publication on the Web with an open access.

Now we are in possession of your files such as: financial statements, intellectual property, accounting records, lawsuits and complaints, personnel and customer files, as well as files containing information on bank details, transactions and other internal documentation.

Furthermore we successfully blocked most of the servers that are of vital importance to you, however upon reaching an agreement, we will unlock them as soon as possible and your employees will be able to resume their daily duties.

We are suggesting a mutually beneficial solution to that issue. You submit a payment to us and we keep the fact that your network has been compromised a secret, delete all your data and provide you with the key to decrypt all your data.

In the event of an agreement, our reputation is a guarantee that all conditions will be fulfilled. No one will ever negotiate with us later on if we don't fulfill our part and we recognise that clearly! We are not a politically motivated group and want nothing more than money. Provided you pay, we will honour all the terms we agreed to during the negotiation process.

In order to contact us, please use chat below, you have 14 days to contact us, after this time a blog post will be made with a timer for 3 days before the data is published and you will no longer be able to contact us.

To contact us follow the instructions:

1) Install and run “Tor Browser” from hxxps://www.torproject.org/download/

贖金要求和勒索手段

與某些僅關注文件加密的勒索軟體威脅不同，SafePay 採取了更積極的方法，將資料外洩納入其攻擊策略。攻擊者聲稱他們已經竊取了財務記錄、智慧財產權、人員和客戶資訊、銀行詳細資訊以及法律文件。他們利用這些被盜資料作為籌碼，警告受害者不遵守規定將導致其機密文件被公開。

受害者必須等待嚴格的期限——14 天才能透過 Tor 網路發起聯繫。如果在此期間沒有進行任何溝通，攻擊者就會發布部落格文章宣布資料洩露，從而加大壓力。該貼文包含被盜文件發布前的三天倒數計時，進一步強迫受害者支付贖金。

支付贖金的風險

雖然支付贖金似乎是重新獲得加密文件存取權的最快方法，但它也伴隨著巨大的風險。網路犯罪分子沒有義務履行他們的承諾，也不能保證他們在收到付款後會提供可用的解密工具。此外，為勒索軟體業者提供資金會鼓勵他們繼續發動攻擊，導致更多受害者成為類似計畫的受害者。

支付贖金的最佳替代方案是維護重要文件的安全、最新備份。然而，即使有備份，從受影響的系統中刪除勒索軟體也是至關重要的。如果不這樣做，可能會導致新檔案或復原的檔案繼續加密，從而導致備份過程無效。

勒索軟體威脅如何傳播

與許多其他威脅（例如Cloak Ransomware或CmbLabs Ransomware ）一樣，SafePay Ransomware 依靠多種分發策略來滲透系統。網路犯罪分子經常使用偽裝成合法通訊的欺騙性電子郵件來誘騙收件者開啟惡意附件或點擊危險連結。這些網路釣魚電子郵件可能偽裝成發票、出貨確認書或需要立即關注的緊急訊息。

另一種常見的感染方法涉及軟體漏洞。過時的作業系統或應用程式為攻擊者提供了部署勒索軟體的切入點，無需用戶互動。此外，SafePay 和類似的威脅可能嵌入盜版軟體、金鑰產生器和破解程式中，一旦執行就會感染系統。

防範勒索軟體的措施

要防範勒索軟體，需要採取主動的網路安全方法。用戶在與來自未知寄件者的電子郵件互動時應小心謹慎，避免未經請求的附件和連結。僅從官方來源下載軟體並保持所有應用程式為最新版本有助於最大限度地降低基於漏洞的攻擊風險。

此外，養成安全的瀏覽習慣（例如避免可疑廣告、彈出視窗和欺騙性網站）可以減少成為網路詐騙受害者的機會。定期將重要文件備份到安全的離線存儲，可確保即使發生攻擊，也可以恢復數據，而無需滿足贖金要求。

最後的想法

SafePay 勒索軟體是網路勒索日益增長的趨勢的一個例子，攻擊者將檔案加密與資料竊取結合起來，迫使受害者支付巨額贖金。雖然贖金要求可能令人生畏，但遵守規定是有風險的，並不能保證資料恢復。相反，採取預防措施（例如維護備份、應用安全更新和線上謹慎）仍然是抵禦勒索軟體威脅的最佳防禦措施。
