Ohrwurm Tool | IEMLabs

 ohrwurm is a small and simple RTP fuzzer that has been successfully tested on a small number of SIP phones. Features:

  • reads SIP messages to get information of the RTP port numbers
  • reading SIP can be omitted by providing the RTP port numbers, so that any RTP traffic can be fuzzed
  • RTCP traffic can be suppressed to avoid that codecs
  • learn about the “noisy line”
  • special care is taken to break RTP handling itself
  • the RTP payload is fuzzed with a constant BER
  • the BER is configurable
  • requires arpspoof from dsniff to do the MITM attack
  • requires both phones to be in a switched LAN (GW operation only works partially)
