Chrome does not expose the same publisher verification data as IDE stores, so this score is deliberately conservative.

AI Security Review
Evidence context: threat category none; evidence quality moderate.
The extension 'Fortnite Breakpoint Live Wallpaper' (developer: [email protected]) returned no findings in the security scan across all categories. The developer's use of an email address instead of a recognized company name is a red flag, as legitimate extensions typically attribute to an organization. However, no malicious code patterns, IoCs, or obfuscation were identified in the scanned files. The extension's name references Fortnite, a popular game, but there is no evidence of impersonating an official extension, as no typosquatting indicators (e.g., Cyrillic characters, similar icons) were present. The low user count (68) and absence of findings suggest minimal risk. The strongest counterargument is that the anonymous developer could indicate malicious intent; however, without any code or network findings, there is no evidence of harm. This aligns with known false-positive patterns where red flags exist but lack supporting evidence. The analysis did not detect custom search engines, credential access, or proxyware functionality. The lack of findings in code-smell, IoC, and obfuscation categories indicates the extension does not exhibit typical malicious behaviors. The extension's description mentions a live wallpaper feature, which is benign functionality. No suspicious domains or network requests were identified in the IoC extraction. The absence of malware signatures and obfuscation further supports a benign classification. According to the decision framework, confirmed_malicious requires strong evidence of intentional harm, which is absent here. The extension does not meet criteria for confirmed_risk, as there are no significant risk indicators. The verdict is likely_false_positive, as the red flags are insufficient without corroborating evidence. The recommended action is no_action, as there is no evidence of malicious behavior. The false_positive_drivers include the absence of malicious findings despite red flags and no code or network indicators of harm. The evidence_quality is moderate due to the lack of findings but the presence of red flags. The confidence is 0.7 because while there are no malicious findings, the developer's anonymity introduces some uncertainty. However, without any supporting evidence, the verdict remains likely_false_positive.
Key Reasons
- No code-smell, IoC, or obfuscation findings detected
- Developer uses anonymous email address
- Extension name references popular game without official affiliation
False Positive Considerations
- Absence of malicious findings despite red flags
- No code or network indicators of harm
Reviewed 2026-04-26; recommended action: no action; model confidence 70%.
