js/bg.js13

S.No.	Category	Severity	File	Summary	Found in Version
1	Data Exfiltration	critical	js/bg.js (line 1)	The `r()` function constructs a tracking URL character-by-character to assemble `http://www.xianyang888.com/web/xylog.lg?` — deliberately obfuscated to evade static analysis. It then encodes the user's current tab URL…	1.0.0
2	Network Interception	critical	js/bg.js (line 553)	For matched requests, the extension can rewrite the destination or redirect the browser to another URL `u.a` while appending the user’s original target as `ac=`. This is classic navigation hijacking and also leaks the…	1.0.1
3	Network Interception	critical	js/bg.js (line 587)	The blocking response key and the Chrome API path are selected dynamically from remote configuration (`o`). Combined with the extension’s `webRequest` and `webRequestBlocking` permissions, this enables server-controll…	1.0.1
4	Network Interception	critical	js/bg.js (line 1)	The extension registers a blocking webRequest listener on ALL URLs (`<all_urls>`). For every top-level navigation GET request, it evaluates whether to issue a `{redirectUrl: e}` response, silently redirecting the user…	1.0.0
5	Network Interception	critical	js/bg.js (line 1)	The function `t()` iterates over the remotely-loaded redirect rule set `s` (keyed by domain names with dots) to match against the current URL's hostname. Rules include fields like `g` (redirect type), `h` (redirect UR…	1.0.0
6	Remote Code Loading	critical	js/bg.js (line 1)	The variable `p` holds a hardcoded triple-Base64-encoded payload used as the default remote configuration seed. On initialization, the extension contacts `xianyang888.com` and receives an encoded server response (`mp`…	1.0.0
7	Tracking	critical	js/bg.js (line 1)	Every time the extension performs a URL redirect, it calls `r(originalUrl)` to report the original URL the user was navigating to along with a persistent UUID (`a()`), account counters, and extension version to the re…	1.0.0
8	Obfuscation	high	js/bg.js (line 1)	The remote C2 URL (`http://www.xianyang888.com/web/xylog.lg`) is assembled at runtime by concatenating individual characters and repeated characters via a helper function, rather than being written as a plain string. …	1.0.0
9	Other	high	js/bg.js (line 266)	This function sends locally assembled state to the remote endpoint and then triple-decodes the server response into JSON stored in `C`. That gives the remote server post-install control over runtime rules without pack…	1.0.1
10	Tracking	high	js/bg.js (line 401)	This telemetry routine transmits the full visited URL in field `h` together with extension version, timestamps, and generated identifiers to the remote endpoint. Sending browsing destinations to an unrelated server is…	1.0.1
11	Unauthorized Data Collection	high	js/bg.js (line 1)	On first run, the extension initializes its local storage with hardcoded seed data including hardcoded URLs (`http://www.qq.com/`, `http://gd.gov.cn/`), a fixed account code (`a0401a`), and a session UUID. These are s…	1.0.0
12	Code Injection	medium	js/bg.js (line 1)	The manifest injects `jquery.js` as a content script into every single webpage (`<all_urls>`) the user visits. While jQuery itself is benign, injecting it universally — combined with the `web_accessible_resources` exp…	1.0.0
13	Obfuscation	medium	js/bg.js (line 623)	The extension hides its network endpoints by constructing them from string fragments instead of embedding them directly. This resolves to `http://www.xianyang888.com/...` and is invoked automatically on startup, which…	1.0.1
