FLORAHOX Activity is conducted using a hybrid operational relay box (ORB) network, which combines two types of infrastructure: compromised devices and leased Virtual Private Servers (VPS). The compromised devices include end-of-life routers and IoT devices, while VPS space is commercially leased and managed by ORB network administrators. This hybrid ORB network allows adversaries to proxy and obscure malicious traffic, making the source of the traffic more difficult to trace.
The FLORAHOX ORB network has been leveraged by multiple cyber threat actors, including China-nexus actors like ZIRCONIUM. These adversaries conduct espionage campaigns through FLORAHOX Activity, relying on the ORB network's ability to funnel traffic through Tor nodes, provisioned VPS servers, and compromised routers to obfuscate malicious traffic.[1]

Standing C0053
Reach is how much of ATT&CK this campaign touches. Coverage is how well defended each thing it does is, as a median per technique rather than a total — a total would just restate the reach. Each figure is ranked against all 56 ATT&CK campaigns only where that population actually spreads. Where most of the population shares one value, a percentile would rank the tie instead of the entity, so the raw value is shown and no rank is claimed.
