begin-coinbse-extnsion-io[.]created[.]app

This domain has been assessed as high risk due to its specific threat type: brand impersonation targeting Coinbase. The site masquerades as a legitimate Coinbase extension, aiming to deceive users into revealing sensitive crypto portfolio information. Given its offline status, immediate action has been taken, but the domain serves as a reminder of persistent phishing tactics in the cryptocurrency space.

Investigation reveals that begin-coinbse-extnsion-io.created.app was created on July 12, 2023, and resolves to IP address 216.150.16.193. It was registered through Tucows Domains Inc. and uses a Let's Encrypt SSL certificate (R13). VirusTotal data shows 13 out of 95 security vendors flagging this domain as malicious, and it appears on one security blocklist. Google Safe Browsing specifically flags it for phishing, and the page title read "Coinbase Extension – Manage Your Crypto Portfolio Directly in Browser." These indicators collectively confirm the domain's fraudulent nature.

To protect against such brand impersonation threats, users should always verify the URL before entering credentials or installing browser extensions. Only download extensions from official app stores or the brand's verified website. Enable two-factor authentication on crypto accounts and monitor for unauthorized transactions. Organizations should implement email and web filtering to block similar domains and educate users about phishing red flags like misspelled domain names and unsolicited prompts.
