Menace actors linked to Chinese language internet hosting infrastructure have established a large community of over 18,000 lively command-and-control servers throughout 48 completely different internet hosting suppliers in current months.
This widespread abuse highlights a critical challenge in how malicious infrastructure can conceal inside trusted networks and cloud providers.
Conventional risk looking strategies that concentrate on particular person IP addresses or domains typically miss the larger image as a result of attackers always change these indicators to keep away from detection.
The analysis reveals that these C2 servers make up about 84 p.c of all malicious exercise noticed inside Chinese language internet hosting environments through the three-month evaluation interval.

Phishing infrastructure accounts for round 13 p.c, whereas malicious open directories and public indicators of compromise collectively symbolize lower than 4 p.c of detected threats.
This reveals that command-and-control operations dominate the risk panorama, with attackers preferring steady infrastructure that may coordinate ongoing campaigns throughout a number of targets.
Hunt.io analysts recognized this in depth infrastructure community utilizing their Host Radar platform, which mixes C2 detection, phishing identification, open listing scanning, and indicator extraction right into a single intelligence system.
Fairly than treating every malicious artifact as remoted, the platform maps these threats again to the internet hosting suppliers and community operators the place they exist. This strategy reveals long-running abuse patterns even when particular person IP addresses change often.
China Unicom emerged as the biggest host of malicious infrastructure, accounting for practically half of all noticed C2 servers with roughly 9,000 detections.
Alibaba Cloud and Tencent every hosted round 3,300 C2 servers, exhibiting that main cloud platforms are closely focused by risk actors who worth their speedy provisioning and excessive availability.
These three suppliers alone symbolize nearly all of detected malicious command-and-control infrastructure inside China.
Infrastructure Focus and Malware Distribution
The malware households working by way of this infrastructure present clear patterns of repeated framework abuse. Mozi botnet dominates with 9,427 distinctive C2 IP addresses, representing greater than half of all noticed command-and-control exercise.
The ARL framework follows with 2,878 C2 endpoints, suggesting in depth misuse of post-exploitation and red-team tooling for malicious functions.

Cobalt Strike seems with 1,204 detections, whereas Vshell and Mirai spherical out the highest 5 with 830 and 703 C2 servers respectively.
This focus means defenders can focus monitoring efforts on shared infrastructure patterns fairly than chasing particular person malware variants that always evolve.
The information reveals that cybercrime operations, botnet infrastructure, and state-linked espionage instruments coexist throughout the identical internet hosting environments.
Campaigns starting from commodity distant entry trojans to stylish APT operations leverage these suppliers, creating a posh risk ecosystem the place conventional indicator-based defenses wrestle to keep up effectiveness.
