1	Code Injection	high	js/layer.js (line 1)	A full-viewport opaque overlay (z-index: 9999999, 100% width/height, position: fixed) is injected into the DOM of every page visited via insertAdjacentHTML. The overlay is toggled on/off via obfuscated command message…	1.0
2	Obfuscation	high	js/back_main.js (line 3)	Every function, variable, and internal message key is deliberately obfuscated with nonsensical names (thelmA, chrYsophyll, wirem_aking, efflu_ve, subglobOid, abduc_es). This is not accidental — legitimate site-blocker…	1.0
3	Obfuscation	high	js/back_listener.js (line 1)	All parameter names are heavily obfuscated (i_ntermediates, oleag_inousness, cry_ptococci, inexplicitly). The background script monitors popup open/close lifecycle (onConnect/onDisconnect) and dispatches obfuscated co…	1.0

8	Privilege Escalation	medium	manifest.json (line 19)	The extension requests global host access plus `webRequest`/`webRequestBlocking`, then injects a content script into every page. That combination gives it the ability to inspect or alter browsing across all sites and …	1.1
