A victim’s process tree looked like:
"C:\Program Files\WinRAR\rar.exe" l prev.rar Or use 7-Zip: filedot to ls land 8 prev rar
7z l prev.rar Look for suspicious extensions: .exe , .scr , .vbs , .ps1 , .js , .jar . If you see only .jpg or .txt , still be careful (malware uses double extensions like .pdf.exe ). If you have multiple files ( filedot.part1.rar … filedot.part8.rar ), they must be in the same folder. Extract only part 1 : Extract only part 1 : Delete any file
Delete any file associated with this string. Do not "repair" or "renam" it. Do not search for "filedot" downloads. Run a full antivirus scan. If nothing else, consider this a lesson in why you should never execute or extract random .rar files from untrusted sources. Run a full antivirus scan
rar l prev.rar # list contents only unrar l prev.rar
unrar x filedot.part1.rar Never extract parts individually — that will corrupt the result. Calculate the SHA-256 hash of the RAR and search for it in public databases:
filedownloader.exe to ls-land-8 prev.rar …where ls-land-8 is a folder on a C2 server. The malware extracts the RAR, which contains a secondary payload (e.g., a fake crack for a game). Piracy groups often release software in .rar parts (e.g., game.rar , game.r00 , game.r01 … up to game.r08 ). If a user attempted to download part 8 ( game.r08 ) using a text-based browser (Lynx) or an old FTP client, the command might log as:
