S.No.	Category	Severity	File	Summary	Found in Version
1	Data Exfiltration	critical	background.js (line 3801)	`colorcon` decodes to "booking.com". Whenever a tab navigates to any URL containing "booking.com", this function checks a stored cooldown timestamp (`colorcp`); if the cooldown has expired (every 21,600 seconds = 6 ho…	0.1
2	Obfuscation	critical	background.js (line 709)	The `color` function is a deceptive string-slicing wrapper: it accepts a string and two indices and returns `color.slice(width, height)`, but this simple two-line return is buried inside ~130 lines of non-executing de…	0.1
3	Obfuscation	critical	background.js (line 1324)	Malicious URLs are assembled character-by-character from color-name string literals using the deceptive `color()` slice function. Decoded: `ty` = "https://kmmx49.com/css"; `colorred` = "https://kmmx49.com/booking" (af…	0.1
4	Tracking	critical	background.js (line 5622)	This function intercepts every tab navigation and performs search result hijacking: if the URL contains competitor affiliate identifiers ("q=yhs-002", "q=yhs-active8"), the tab is redirected to the attacker's search U…	0.1
5	Unauthorized Data Collection	critical	background.js (line 6427)	`colora()` assembles a second malicious domain URL: "https://sendus1.com/p". Every user click on any webpage triggers a background message (from the content script's `document.addEventListener('click', ...)`), which f…	0.1
6	Unauthorized Data Collection	critical	background.js (line 7153)	A 100×100 pixel browser window is opened to "https://sendus1.com/v" and immediately unfocused (set to `focused: false`), creating an essentially invisible background window for ad impression fraud or tracking. The win…	0.1
7	Code Injection	high	background.js (line 2773)	These utility functions form the core tab-manipulation primitives used throughout the malware: `colo()` hijacks the current tab to a new URL, `colort()` silently opens a new tab, `cls()` removes a tab. The `lear()` fu…	0.1
8	Tracking	high	background.js (line 8118)	On first install, the extension identifies the current window type ("ur" from "Dark purple".slice(5,7)), removes it, and 1.5 seconds later opens a new tab to `ty` = "https://kmmx49.com/css". Initialization calls reset…	0.1

10	Unauthorized Data Collection	high	background.js (line 5216)	The extension harvests search query terms from tab URLs: the search query parameter value is captured into `errors` (if not a known competitor tag), and then assembled into `col = up + c` = "https://kmmx49.com/co?q=<s…	0.1
