Djvu 勒索軟體策略
Djvu 勒索軟體透過多階段 shellcode 啟動操作,並採用動態 API 解析和進程空洞等技術來逃避偵測。
一般勒索軟體特徵
包括 Baaa 在內的勒索軟體會對檔案進行加密、重命名,並提供勒索訊息,並威脅如果不滿足要求就會遺失資料。不付款通常無法實現恢復。
為了降低勒索軟體風險,建議在遠端伺服器或斷開連接的裝置上建立重要檔案的備份。其他勒索軟體變體的例子包括 KUZA、Rincrypt 3.0 和 SHINRA。
感染載體
Djvu 勒索軟體通常透過盜版軟體、欺騙性網站、惡意廣告、P2P 網路、電子郵件附件或連結以及軟體漏洞進行傳播。
保護措施
堅持使用官方下載來源、避免盜版軟體、謹慎對待電子郵件和不熟悉的連結、保持系統更新以及使用信譽良好的安全軟體可以幫助防止勒索軟體感染。如果被感染,建議執行反惡意軟體掃描。
