Permanent link Tool: KopiLuwak

NamesKopiLuwak
CategoryMalware
TypeReconnaissance, Backdoor
Description(Kaspersky) The KopiLuwak script is decoded by macro code very similar to that previously seen with IcedCoffee, but the resulting script is not the final step. This script is executed with a parameter used as a key to RC4 decrypt an additional layer of javascript that contains the system information collection and command and control beaconing functionality. KopiLuwak performs a more comprehensive system and network reconnaissance collection, and like IcedCoffee leaves very little on disk for investigators to discover other than the base script.
