5	Network Interception	critical	js/background.js (line 667)	Rewrites outgoing request headers on every HTTP(S) request: removes a server-configured custom header, copies its value into `Accept`, and for background (tabId<0) requests forges the `Referer` header using rules from…	2.3.1
6	Remote Code Loading	critical	js/background.js (line 398)	The extension beacons a persistent per-user UID, extension ID and version to an attacker-controlled C2 (eqmix.net) and pulls down remote JSON config that drives runtime behavior (header filtering rules, redirect chain…	2.3.1
