calio[.]cc

On 8 February 2026 the domain calio.cc was registered through NICENIC INTERNATIONAL GROUP CO., LIMITED and delegated to the Cloudflare name servers arch.ns.cloudflare.com and lola.ns.cloudflare.com. The domain currently resolves to the IP address 104.21.32.19, which is associated with Cloudflare's content‑delivery network. Multiple threat‑intel sources have categorized the site as a generic phishing operation and assigned it a high risk rating. PhishDestroy has already added the domain to its blocklist, and a separate security blocklist also contains the entry, giving a total of one external blocklist listing.

VirusTotal scans show that 3 of 91 antivirus and URL‑reputation engines flagged the domain as malicious, indicating partial detection across the ecosystem. The domain remains active as of the report date, 30 July 2026, and no public takedown has been recorded. Publicly available details such as the page title, SSL certificate information, or Safe Browsing classification are not currently disclosed, leaving the exact content and delivery mechanisms uncertain. The lack of additional context means that defenders cannot rely on content‑specific signatures and must instead apply network‑level controls.

Organizations should add calio.cc and its resolved IP 104.21.32.19 to outbound and inbound filtering rules, monitor DNS queries for the domain, and enforce web‑gateway policies that block known phishing URLs. Continuous re‑inspection of VirusTotal and other multi‑engine scanners is recommended to capture any new detections. Immediate remediation includes isolating any compromised credentials and educating users about unsolicited login prompts that may originate from this domain.
