secur-rabby-learn[.]teachable[.]com

Analysis of the domain secur-rabby-learn.teachable.com indicates it was actively impersonating Rabby, a crypto wallet service, as of its operational period. The domain was registered on February 21, 2026, through Amazon Registrar, Inc., and resolved to the IP address 34.54.192.65, hosted under AS396982 (Google LLC) in the United States. Infrastructure analysis reveals the use of Cloudflare nameservers (ian.ns.cloudflare.com, nina.ns.cloudflare.com), alongside technologies including Amazon ELB, Google Cloud, Amazon Web Services, Mailgun, Google Cloud CDN, and HTTP/3. The SSL certificate was issued by Google Trust Services (WR3), a common provider for both legitimate and malicious domains. The page title, 'Rabby Wallet | Secure and User-Friendly Crypto Management,' directly mirrors the branding of the legitimate Rabby wallet, confirming the intent to deceive users.

The domain was flagged by at least one security blocklist (PhishDestroy) and classified as a crypto scam. As of the latest assessment on July 25, 2026, the domain returns an HTTP 404 status, indicating it is offline. No active detections were recorded by the 93 vendors that scanned the domain on VirusTotal, though this absence does not confirm safety. The domain's hosting and infrastructure choices align with patterns observed in phishing campaigns targeting cryptocurrency users, leveraging trusted cloud providers to evade initial scrutiny. Defenders should treat this domain as confirmed malicious infrastructure for brand impersonation.

While currently offline, the domain may resurface or be repurposed. Monitoring for re-activation, DNS changes, or SSL certificate updates is recommended. Organizations should update blocklists to include this domain and its resolved IP, particularly in environments where Rabby or similar crypto services are used. The use of Teachable's subdomain platform suggests an attempt to exploit perceived legitimacy, a tactic observed in other phishing campaigns.
