rabby-web[.]at

This domain, rabby-web.at, poses a direct threat as a brand impersonation site targeting Rabby, a cryptocurrency wallet service. Analysis indicates the domain was designed to mimic the official Rabby platform, presenting itself as a legitimate extension download and login portal. Such impersonation is commonly used to distribute malicious browser extensions or harvest user credentials, potentially leading to unauthorized access to crypto wallets and financial theft. The page title, 'Rabby Wallet | Extension Download | Login,' reinforces the deception by closely resembling authentic Rabby branding, increasing the likelihood of user engagement under false pretenses.

Technical evidence confirms the domain's malicious nature. VirusTotal reports 20 out of 95 security vendors flagging rabby-web.at as malicious, while it appears on one security blocklist. The domain was registered on March 28, 2026, through Timeweb.ru, a registrar frequently associated with suspicious domains. Infrastructure analysis reveals the domain resolved to the IP address 213.226.125.138, hosted by TimeWeb Ltd in Russia. The SSL certificate, issued by Let's Encrypt (R12), does not mitigate the risk, as threat actors commonly use valid certificates to lend false legitimacy to malicious sites. The domain's current offline status suggests takedown efforts, but its prior activity remains a concern for users who may have interacted with it.

Users who visited rabby-web.at or downloaded content from it should take immediate action. Disconnect any devices used to access the site from networks and perform a full antivirus scan to detect potential malware. If credentials were entered, reset passwords for Rabby and any other accounts using the same credentials, and enable multi-factor authentication where available. Monitor crypto wallet transactions for unauthorized activity and consider revoking access to any suspicious browser extensions. Given the domain's association with brand impersonation, users should verify the authenticity of any Rabby-related communications or downloads by cross-referencing with the official Rabby website or support channels.
