Newly registered Tempe network draws cybersecurity attention
Original: ASN: 398101 Location: Tempe, US Added: 2026-09-29T14:15 # shodansafari # infosec
Security researchers are flagging a newly registered network, autonomous system number 398101, based in Tempe, Arizona, as of late September. The entry, surfaced through network-scanning tools used in the infosec community, is being shared among researchers who track new infrastructure for potential malicious hosting, botnet activity or other suspicious behavior. No confirmed threat has been linked to the network so far.
Why now: Infosec researchers routinely monitor newly registered autonomous systems for signs of malicious infrastructure, so a fresh Tempe-based ASN is being circulated for scrutiny.
