uphldd[.]zapier[.]app

This domain, uphldd.zapier.app, is identified as a high-risk credential phishing endpoint targeting users through deceptive login portals. Analysis indicates no direct association with known brand impersonation or drainer kits, though the infrastructure aligns with generic phishing campaigns designed to harvest authentication credentials. The domain operates under a subdomain of a legitimate automation platform, a tactic frequently exploited to evade initial suspicion and bypass basic security filters. Infrastructure analysis reveals the following technical indicators: the domain resolves to IP address 64.239.109.1, hosted on AS16509 (Amazon.com, Inc.) in the United States. It is flagged by 12 out of 95 security vendors on VirusTotal, with two independent blocklists listing it as malicious. The SSL certificate is issued by Let's Encrypt (serial YR1), a common choice for both legitimate and malicious sites. No registrar or creation date metadata is publicly available due to the subdomain structure, though the parent domain (zapier.app) is registered through MarkMonitor. Google Safe Browsing (GSB) currently lists the domain as unsafe, reinforcing its classification as an active threat. As of the latest assessment, uphldd.zapier.app remains active and unresolved, with no evidence of takedown or mitigation. Response actions include immediate blocking at the DNS and proxy levels, alongside endpoint detection rules to prevent user interaction. The remaining risk is elevated due to the domain's persistence, low detection saturation (12.6% on VirusTotal), and use of a reputable hosting provider, which may delay automated remediation. Organizations are advised to enforce strict access controls, monitor for credential reuse, and update security policies to flag subdomains of automation platforms as potential phishing vectors.
