# PeddleCheap
Pcaps for PeddleCheap and implant communication + script for interpreting pcaps.Decryptor script:
dp_decrypt.py: script to decrypt (and verbosely explain) the traffic when HTTP Proxy is usedPcap files:
forward_level3_tcp_port_1163.pcap: level3 standard tcp implant with PeddleCheap doing a forward connection to implant
forward_level4_tcp_port_1167.pcap: level4 standard tcp implant with PeddleCheap doing a forward connection to implant
reverse_level3_http_port_80.pcap: level3 http proxy implant with implant doing reverse connection to PeddleCheap
reverse_level3_http_port_443.pcap: level3 http proxy implant with implant doing reverse connection to PeddleCheap
reverse_level3_tcp_port_53.pcap: level3 standard tcp implant with implant doing reverse connection to PeddleCheapSupporting files:
00041-pc_listen_2017_10_16_09h37m12s.966.xml: DanderSpritz log file (corresponds to reverse_level3_http_port_80.pcap)
successful_reverse_connection_port80.txt: another DanderSpritz log file (corresponds to reverse_level3_http_port_80.pcap)
Dsz_Implant_Pc.dll: PeddleCheap uploads this file to have it executed by the implant
DszLpCore.exe: executable that listens to open ports on the DanderSpritz host
PeddleCheap_Lp.dll: imported by DszLpCore.exe, communicates with the implant
PeddleCheap_2017_10_16_09h32m09s.409: directory containing implant (for reverse_level3_http_port_80.pcap) as well as the default public/private keysSample output when ran against reverse_level3_http_port_80.pcap:
