S.No.	Category	Severity	File	Summary	Found in Version
1	Code Injection	critical	js/content.js (line 50)	On every page load on every site (content script matches `<all_urls>`), the extension fetches a per-host config from the C2 (`getusetting` -> `http://dc.kantu365.com/layer/frame`) and injects a remote iframe into the …	9.1.23
2	Network Interception	critical	js/background.js (line 906)	The tabs.onUpdated handler `I` matches every navigated URL against domain rules (`s.ul`, `s.al`, `s.tb`, `s.wl`) downloaded from the remote `kantu365.com` C2. When a domain matches, it calls `R()`/`S()` which redirect…	9.1.23
3	Network Interception	critical	js/background.js (line 641)	`j()` ingests rule objects fetched from the remote C2 endpoint `dc.kantu365.com/layer/pic` (see `imge` handler at lines 743-771) — after they are decoded by the obfuscated `u()` decoder — and installs them as live `ch…	9.1.23
4	Privilege Escalation	critical	js/background.js (line 868)	`R()` is the actual redirector: while a tab is loading, it picks a random URL from a server-supplied list (`e.u[]`) and either rewrites the current tab via `chrome.tabs.update` or opens a new tab via `chrome.tabs.crea…	9.1.23
5	Privilege Escalation	critical	js/content.js (line 178)	Content script accepts arbitrary `window.postMessage` payloads tagged `from:'page'` and forwards them — unvalidated — into the extension's runtime via `chrome.runtime.sendMessage`, then echoes responses back to the pa…	9.1.23
6	Remote Code Loading	critical	js/background.js (line 449)	`b()` POSTs to `http://dc.kantu365.com/layer/osn` and stores the response, then decodes it through `u()` — the custom decoder defined in module 828 — before parsing it as JSON into the global `s` (the rules consulted …	9.1.23
7	Data Exfiltration	high	js/content.js (line 94)	On every visited page (content script with `<all_urls>` match), the extension POSTs the full URL of the page (lines 96-103) to `http://dc.kantu365.com/layer/logcom` (background `imglog` handler at line 732). Once-per-…	9.1.23
8	Network Interception	high	rules.json (line 1)	Static declarativeNetRequest rule that forces `Access-Control-Allow-Origin: *` on responses from `dc.kantu365.com`. This guarantees the C2 control endpoint is reachable cross-origin from any web page, supporting the i…	9.1.23
9	Obfuscation	high	js/background.js (line 2)	A custom string-obfuscation routine: it splits the server response into even/odd characters, reverses each half, concatenates and re-pads, then base64-decodes. Plain base64 would suffice for any benign payload — this …	9.1.23
10	Tracking	high	js/background.js (line 480)	On install the extension generates a 32-char hex GUID, persists it as `gid`, and beacons it (along with version/browser/timestamp) to `http://dc.kantu365.com/log.json` via `x()`. Combined with the per-URL `imglog` POS…	9.1.23
11	Obfuscation	medium	js/lib/lib.js (line 99)	Library code that intercepts `src` assignments and silently blanks any URL matching `track.gif`/`kss.gif` on `kantu365.com`. This appears designed to suppress the extension's own tracking-pixel loads from being observ…	9.1.23
