ad-id-core-2d3s3jrjy-qianyu-data-systems[.]vercel[.]app

ad-id-core-2d3s3jrjy-qianyu-data-systems.vercel.app was observed in a recent security feed and is currently listed as an active generic phishing site under investigation. The domain is hosted on the Vercel platform, as indicated by the ".vercel.app" suffix, which is commonly used for temporary or development deployments. No public WHOIS data, IP address, ASN, or geographic location has been disclosed in the available intelligence. The only concrete indicator is that the domain has been blocked by the PhishDestroy filtering service and appears on a single external blocklist.

No additional analysis such as SSL certificate details, HTTP response codes, page title, Safe Browsing verdicts, or malware signatures is available, leaving the operational characteristics of the site undefined. It is therefore uncertain whether the site is actively serving credential‑harvesting pages, serving malicious payloads, or merely parked for future abuse. Defenders should proactively add the full hostname to deny lists, enforce URL filtering rules that block traffic to this domain, and monitor DNS queries for resolution attempts.

Email security gateways should flag or quarantine messages that contain links to this hostname, given its classification as a generic phishing resource. Continuous observation of threat‑intelligence feeds for new detections, changes in blocklist status, or the emergence of associated indicators of compromise is recommended. Until further forensic evidence becomes available, precautionary blocking and vigilant monitoring represent the most effective mitigation steps.
