Tool: KopiLuwak| Names | KopiLuwak | |
| Category | Malware | |
| Type | Reconnaissance, 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. | |
