Malware Shellfolder And Lotuslite Chains
This rule detects files associated with two distinct malware chains, ShellFolder and LOTUSLITE, which have been observed in campaigns leveraging Middle East conflict themes as bait. The ShellFolder chain detection focuses on specific file names like 'ShellFolder.exe', 'ShellFolderDepend.dll', and 'BaiNetdisk', along with a unique decryption key '20260301@@@'. The LOTUSLITE downloader chain detection identifies specific DLLs ('libmemobook.dll', 'kugou.dll'), folder paths ('C:\ProgramData\CClipboardCm\', 'C:\ProgramData\WebFeatures\'), executable names ('WebFeatures.exe'), and hardcoded URLs/IP addresses ('www.e-kflower.com', '172.81.60.97') used for persistence and downloading next-stage malware. The rule aims to identify concrete indicators of compromise rather than broad patterns, focusing on the specific artifacts reported in related threat intelligence.
