ledger[.]userdiagnosis[.]com

This domain is flagged as an elevated-risk brand impersonation threat specifically targeting Ledger, a provider of cryptocurrency hardware wallets. The site mimics legitimate Ledger branding to deceive users into disclosing sensitive wallet credentials or installing malicious software designed to drain crypto assets. Analysis indicates a deliberate attempt to exploit trust in the Ledger brand, with infrastructure configured to evade initial detection while maximizing victim exposure. Infrastructure analysis reveals multiple high-confidence threat indicators. The domain ledger.userdiagnosis.com was registered on September 01, 2025, through Tucows Domains Inc., and resolves to the IP address 45.153.34.48, hosted on AS51396 (Pfcloud UG) in the Netherlands. The SSL certificate is issued via Plesk, a common hosting control panel, which may indicate automated or low-effort deployment. Security vendors on VirusTotal flagged the domain at a rate of 17/95, reflecting moderate consensus on its malicious nature. The domain appears on two security blocklists, PhishDestroy and PhishingDB, and was taken offline following detection, though its infrastructure remains a potential vector for future campaigns. Mitigation requires immediate action from both users and security teams. Users who accessed the domain should assume credential compromise and revoke any wallet permissions granted during interaction. They must verify wallet integrity offline, scan for unauthorized transactions, and rotate recovery phrases if exposure is suspected. Security teams should block the domain and IP at the network level, monitor for related subdomains or lookalike domains registered through the same registrar, and update detection rules to flag Plesk-signed certificates resolving to AS51396. Proactive monitoring of newly registered domains containing 'ledger' or similar branding is recommended to preempt future impersonation attempts.
