2	Credential Theft	critical	content.js (line 731)	The content script extracts the current page's domain name, uses it to look up a query-parameter name from the decrypted targeting table `v` (e.g., `v['google'] = 'code'`), then reads that URL parameter's value from `…	1.2.5
3	Data Exfiltration	critical	content.js (line 1189)	The stolen URL parameter value `p` is exfiltrated to `https://amoffar.com` as a query parameter alongside the user's UUID (`o`) and the matched parameter name (`v[M]`), building a URL of the form `https://amoffar.com?…	1.2.5
4	Obfuscation	critical	content.js (line 154)	The content script XOR-decrypts the `keepalive` blob (fetched from amoffar.com and stored in local storage) using the `app_id` UUID as the repeating key, then JSON-parses the result into targeting rules `[v, O]`. This…	1.2.5

7	Tracking	high	background.js (line 71)	The extension registers a remote tracking URL at amoffar.com that fires on uninstall, transmitting the user's unique UUID app_id to a third-party server. This is unauthorized telemetry — the extension's stated purpose…	1.2.5

9	Unauthorized Data Collection	high	manifest.json (line 23)	The content script is injected into every HTTP and HTTPS page with `run_at: document_start`, meaning it executes before the page's own scripts and before the DOM is built. This maximises its access to page state and e…	1.2.5
