Abstract
Methods and systems for detecting new calls from an existing spam or robocaller and aggregating calls that originate from the same infrastructure using a telephony honeypot are disclosed. An example method may receive a telephone call to a telephony honeypot and store metadata and a call audio recording associated with the telephone call. A transcript may be created of the call audio recording. Audio features may be extracted from the call audio recording. The transcript may be compared to other previously-received transcripts in order to determine a similarity between the call and previously-received calls. Audio features and metadata may also be compared to determine whether the call is similar to other previously-received calls. If a call is similar, the call may be identified with the same spam campaign or robocaller as the similar, previously-received call.
