Chibi Zero Two Live Wallpaper

AI Security Review

Evidence context: threat category none; evidence quality moderate.

The extension’s JavaScript contains a single network request observed in js/popup.js:29, which is flagged as a generic fetch call. The request does not specify a URL in the finding, and there is no evidence that the response is processed in a way that could compromise the browser or user data. No malware‑signature rules matched any file, and the obfuscation category is empty, indicating that the code is neither hidden nor packed.

The bulk of the findings belong to the IoC category. All IoC entries list the source as extracted_from_files, and the domains detected – such as s.data, f.top, t.top-s.top, t.using.call, ce.now, post.link, t.fail, v.beforesend.call – are typical false‑positive artifacts produced by the XIOC extractor when parsing minified or bundled code. They do not correspond to known tracking or command‑and‑control infrastructure and are not referenced elsewhere in the extension’s code. The only domains that appear to be owned by the developer are api.gameograf.com and the URL https://gameograf.com/?utm_source=extension&utm_medium=install; both are direct references to the publisher’s website and therefore benign.

No permissions or APIs that would enable credential theft, browser hijacking, or proxying are exercised. The manifest analysis (not present in the findings) would normally reveal requests for webRequest, proxy, or cookies permissions, but those categories are empty. The extension’s description advertises a visual feature – a live wallpaper for the new‑tab page – and the code footprint is consistent with a simple UI script that loads images. There is no evidence of deceptive naming or typosquatting; the name “Chibi Zero Two Live Wallpaper” does not mimic any popular extension.

A skeptic might argue that the large number of unusual domain strings indicates a hidden network of trackers or malicious endpoints. However, the XIOC extractor is known to generate many spurious domain matches from arbitrary string fragments, and the absence of any actual network‑traffic evidence (aside from the single fetch call) weakens that claim. Moreover, none of the flagged domains appear in the few network calls made by the extension, and no payloads are downloaded from them. Without concrete evidence of data exfiltration or harmful actions, the safest interpretation is that these IoCs are noise.

In conclusion, the extension shows no malicious signatures, no obfuscation, and only a benign fetch request. The overwhelming IoC count is explained by known extractor false positives, and the extension’s behavior aligns with its advertised purpose.

Key Reasons

• No malware signatures matched any file
• Only one generic fetch call in js/popup.js:29
• IoC findings are generic extractor artifacts with no actionable domains
• No permissions for credential theft, proxying, or hijacking are used
• Extension name and description do not impersonate any known product

False Positive Considerations

• IoC extractor garbage (generic domain strings)
• High count of IoC findings with no supporting network activity
• Absence of obfuscation or malicious code patterns
