app[.]merkl[.]us

Analysis of the domain app.merkl.us indicates it was actively flagged as phishing infrastructure prior to being taken offline on July 24, 2026. The domain, registered on February 27, 2026, through PDR Ltd. d/b/a PublicDomainRegistry.com, resolved to the IP address 104.21.24.73, hosted on Cloudflare's network (AS13335) in the United States. Nameservers audrey.ns.cloudflare.com and rohin.ns.cloudflare.com were in use, consistent with Cloudflare's DNS infrastructure. No SSL certificate was detected, increasing the likelihood of unencrypted credential harvesting or data interception.

The page title, 'Merkl | Opportunities,' suggests an attempt to mimic a legitimate platform, though the exact target or brand impersonation remains unconfirmed due to limited forensic data. One of 93 security vendors on VirusTotal flagged the domain as malicious, and it appeared on at least one security blocklist, corroborating its classification as phishing infrastructure. The domain was also blocked by PhishDestroy, a specialized anti-phishing service, further supporting its malicious designation. Infrastructure analysis reveals the use of Cloudflare, a common tactic among threat actors to obscure hosting origins and evade takedowns.

The domain's creation date, six months prior to its detection, aligns with typical phishing campaign timelines, where domains are registered in advance of deployment. Defenders should treat this domain as confirmed phishing infrastructure and monitor for related indicators, including associated IP addresses, nameservers, and registration patterns. Organizations using PhishDestroy or similar blocklists may have already mitigated exposure, but retrospective log analysis is recommended to identify any prior interactions with this domain.
