captcha--krab3--at[.]ru

The domain captcha--krab3--at.ru was registered on February 21, 2026. Since its appearance, it has been linked to generic phishing campaigns. AlienVault OTX has indexed the domain in a single threat‑intel pulse, indicating that at least one researcher has observed malicious activity associated with it. The domain is currently listed as offline, and PhishDestroy has taken it down, confirming that the infrastructure is no longer reachable. VirusTotal analysis shows that 16 of 93 scanning engines flagged the domain as malicious, suggesting a moderate detection confidence across multiple vendors.

The domain also appears on one public blocklist, which further corroborates its reputation as a threat vector. No additional public data such as hosting IP, ASN, SSL certificate details, or page title have been disclosed in the available intelligence. Consequently, the precise hosting location, certificate status, and content served by the site remain unknown. Defenders should continue to block any outbound connections to captcha--krab3--at.ru, ensure that internal DNS resolvers return NXDOMAIN or a sinkhole response, and monitor for any residual traffic that may target the domain’s former IP addresses.

Adding the domain to local blocklists and configuring web filters to deny requests to the .ru TLD can reduce exposure. Organizations should also review OTX pulse details for any IoCs such as URLs, file hashes, or email subjects that may be related to this campaign. Because the site is offline, immediate risk is low, but the detection history indicates that threat actors have used this domain to host phishing content, and similar patterns may reappear under new domains. Ongoing vigilance and rapid sharing of any new indicators with community platforms are advised.
