147.124.221.76 has a threat confidence score of 75%. This IP address from United States (AS396073, Majestic Hosting Solutions, LLC) has been observed in 8 honeypot sessions targeting SIP protocols. First observed on April 18, 2026, most recently active April 18, 2026.
Represents an unsolicited SIP INVITE request targeting a long numeric destination, with the request accepted for processing by the SIP server (100 Trying). While the Call-ID format appears consistent with legitimate SIP implementations, the absence of prior registration and the use of a PSTN-style numeric target indicate probing of call routing or gateway behavior rather than normal call setup. This behavior is commonly observed during early-stage toll-fraud reconnaissance or PBX routing validation.
