This domain, app-oai-whatshktw.com, is flagged as a brand impersonation phishing campaign targeting Google. The domain was created on October 08, 2025, and has since been taken offline. The page title, 'whatsapp手機網頁版| 如何設置提醒功能：不再錯過重要日程,' suggests that the site was designed to mimic a WhatsApp mobile web page, potentially to trick users into divulging sensitive information. The domain is registered through Dominet (HK) Limited, and the IP address 103.99.210.58 is located in South Korea, under the ASN AS205960 HDTIDC LIMITED.

Analysis indicates that the domain lacks an SSL certificate, which is a common indicator of a non-secure and potentially malicious site. The domain has been flagged by 15 of 95 security vendors, and it appears on one security blocklist, specifically PhishDestroy. The Scamadviser trust score for this domain is 1/100, and the Gridinsoft trust score is 0/100, both indicating a very high risk of fraud.

The domain has been referenced in 17 threat intelligence pulses on AlienVault OTX, further corroborating its involvement in malicious activities. Given the elevated risk level and the specific targeting of Google, network defenders and security teams should ensure that this domain is blocked and that users are warned against accessing any related content. The exact content and functionality of the site have not been fully analyzed, but the available evidence strongly suggests that it was used to carry out a brand impersonation scam.
