Chinese APT group Weaver Ant breached and maintained a foothold on a large Asian telco network for four years using compromised Zyxel CPE routers for cyber espionage.

Advisory warns that state-backed Chinese hackers have deep penetration into "major" US telcos, and are getting in by compromising an assortment of networking equipment and routers.
