解決方法
密碼太簡單, 千萬不要把密碼改成12345678, 把admin賬戶停用, 購買biticon, 電郵給駭客 及 過數給客戶 交交贖款, 最後等駭客給解決方便;
奇怪所有檔案不是被加碼 及 在file station內所有檔案不見了,過去synology 或 qnap中了Ransomware, 所有檔案被加碼, 但今次NAS 中的 Ransomware, file station內所有資料夾不見了及所有檔案都不見了, 很明顯今次是保案漏洞
什麼叫即ransomware:
勒索軟體(ransomware)是一種流行的木馬,通過騷擾、恐嚇甚至採用綁架用戶檔等方式,使用戶數據資產或計算資源無法正常使用,並以此為條件向用戶勒索錢財。這類用戶數據資產包括文檔、郵件、資料庫、源代碼、圖片、壓縮檔等多種檔。贖金形式包括真實貨幣、比特幣或其他虛擬貨幣。
一般來說,勒索軟體作者還會設定一個支付時限,有時贖金數目也會隨著時間的推移而上漲。有時,即使用戶支付了贖金,最終也還是無法正常使用系統,無法還原被加密的檔。
為什麼NAS 會中 Ransomware 病毒?
勒索病毒主要通過三種途徑傳播:漏洞、郵件和廣告推廣
1:網站木馬
用戶流覽有安全威脅的網站,系統被植入木馬感染ceber勒索病毒。
2:郵件傳播
這種傳播方式也是病毒界老套路的傳播方式。病毒執行體附著於郵件附件的docx、XLS、TXT等檔中,攻擊者以廣撒網的方式大量傳播垃圾郵件、釣魚郵件,一旦收件人打開郵件附件或者點擊郵件中的鏈接地址,勒索軟體會以用戶看不見的形式在後臺靜默安裝,實施勒索。
3:漏洞傳播
這種傳播方式是這幾年非常流行的病毒傳播方式。通過網路、系統、應用程式的漏洞攻擊用戶。例如今年在國內氾濫的WannaCry就是這樣的典型:利用微軟445端口協議漏洞,感染傳播網內電腦。
防止感染該類病毒 ,一般預防為主;
1、 不要打開陌生人或來歷不明的郵件,防止通過郵件附件的攻擊;
2、 不要點擊office宏運行提示,避免來自office組件的病毒感染;
3、 軟體從正規途徑下載,不要雙擊打開.js、.vbs等尾碼名檔;
4、 升級到最新的防病毒等安全特徵庫;
5、 升級防病毒軟體到最新的防病毒庫;
6、 定期異地備份電腦中重要的數據和文件;
