AS4134

Cybersecurity observers are tracking activity on AS4134, a network registered in Shenzhen, China, which was added to monitoring lists on 6 October 2026. The autonomous system is one of the largest Chinese network operators, and its appearance in threat-tracking discussions has drawn attention from information security researchers following exposed internet-facing devices.

AS4134, the China Telecom autonomous system serving Jiaxing, Zhejiang, is being noted in cybersecurity discussions after a network registration entry dated October 2026 circulated among infosec observers. Practitioners track autonomous system numbers like this one to map internet infrastructure, spot newly registered ranges, and monitor hosting patterns commonly associated with scanning and reconnaissance activity.

A cybersecurity feed entry lists AS4134, the autonomous system number operated by Chinanet, with a location in Nanjing, China, timestamped 30 September 2026. The entry carries no further detail on why the network was added or what activity was observed on it. AS4134 is one of China's largest backbone networks, so listing it as a location marker rather than a threat indicator is unusual.
