krab-5cc-5[.]ru

Analysis of krab-5cc-5.ru shows a recently registered domain created on March 07, 2026 through the REGRU-RU registrar. The domain resolves to IP address 205.185.113.136, which is assigned to AS53667 FranTech Solutions in the United States. The hosting server runs Nginx and presents a Let's Encrypt TLS certificate, indicating standard HTTPS support. The page title returned by the web server is "Сеть обмена данными CC для распределённых вычислений krab5cc," which translates to a data exchange network for distributed computing, suggesting the site attempts to present itself as a legitimate data‑sharing service.

VirusTotal records indicate that 2 of 94 security vendors have flagged the domain, providing modest but notable detection. The domain has been added to a single security blocklist and is actively blocked by the PhishDestroy mitigation service. Current monitoring shows the site is taken offline, but the infrastructure—registrar, nameservers (ns1.reg.ru, ns2.reg.ru), hosting IP, and TLS certificate—remains observable. Defenders should continue to block the associated IP range, enforce DNS filtering for the domain, and monitor for any re‑activation or replication of the same hosting footprint.

Given the limited detection footprint, additional passive DNS and certificate transparency monitoring is recommended to capture potential redeployment of the infrastructure. The precise malicious payload or targeted brand has not been disclosed, so threat actors may be leveraging the site for generic credential harvesting or data‑exfiltration. Organizations should remain vigilant for communications referencing a "CC data exchange" service and apply standard phishing defenses, including user education, multi‑factor authentication, and email gateway filtering.
