app-rabby[.]net

The domain app-rabby.net is currently offline but exhibits multiple indicators of a high‑risk brand‑impersonation campaign targeting the Arbitrum ecosystem. Infrastructure analysis shows the domain resolves to IP address 188.114.96.3, which is owned by Cloudflare, Inc. (AS13335) and geolocated to the United States. The domain was registered on September 09, 2025 through Web Commerce Communications Limited and is served by the Cloudflare nameservers javon.ns.cloudflare.com and miki.ns.cloudflare.com. No SSL/TLS certificate is present, meaning any HTTP connections would be unencrypted.

Reputation services rate the site poorly: Scamadviser assigns a trust score of 16 out of 100, and the domain appears on a single security blocklist. Google Safe Browsing flags the site for social engineering, and VirusTotal records 15 of 95 scanned security vendors marking the domain as malicious. The site is also listed by PhishDestroy, confirming its classification as a wallet/seed phishing operation. The page title returned from earlier crawls is "Rabby Wallet," and the campaign explicitly impersonates the Arbitrum brand.

Uncertainty remains around the current content of the site because it is taken offline, and no HTTP response headers or body content are available for deeper analysis. Defenders should immediately block traffic to app-rabby.net at the network perimeter, add the domain and its resolving IP to threat‑intelligence feeds, and monitor for newly registered domains that share similar naming patterns or use the same registrar. Continuous observation of Cloudflare‑hosted domains targeting crypto wallets is advised, and security rules should be updated to flag any attempts to deliver wallet or seed‑phrase requests originating from domains lacking TLS certificates and exhibiting low trust scores.
