Every JS file in the extension is a trivial favicon-replacement script: each one waits for DOMContentLoaded, selects the page's favicon link element, and sets its href to an inline data-URI encoding of the old Roblox logo (a small ICO or large ICO image). All CSS files inject inline SVG data-URIs via CSS background-image to replace Roblox's wordmark logo on their respective subdomains. There is no network request, no eval, no dynamic code loading, no data exfiltration, and no obfuscation beyond what is inherent to base64-encoding image data. The ML score of 0.40 was almost certainly driven by the large base64 blobs in JS files (inflating js_appendchild, total_js_size_bytes) which are logo image data, not malicious payloads. The publisher reputation flag ( malicious leave-one-out) is the only residual concern, but the code is fully auditable and entirely benign.
