This threat involves a phishing campaign identified through Open Source Intelligence (OSINT) methods, consisting of 97 distinct phishing domains distributed across 10 different IP addresses. Phishing is a social engineering attack technique where attackers create fraudulent websites or domains that mimic legitimate services to deceive users into divulging sensitive information such as login credentials, financial data, or personal details. The distribution of these domains over multiple IP addresses suggests an attempt to evade detection and takedown efforts by spreading the infrastructure. The source of this intelligence is CIRCL, a reputable Computer Incident Response Center, indicating credible observation of this phishing infrastructure. The campaign's low severity rating and the absence of known exploits in the wild suggest that while the phishing infrastructure is active, it may not be currently widespread or highly effective. The threat level of 3 (on an unspecified scale) and an analysis score of 1 imply limited immediate impact or sophistication. The adversary infrastructure is marked as compromised, which could mean that the IPs or domains used are hijacked or abused resources rather than attacker-owned assets. No specific affected products or software versions are identified, as this is a phishing infrastructure rather than a software vulnerability. The lack of CVEs or CWEs further supports this. The campaign's TLP (Traffic Light Protocol) is white, indicating the information is publicly shareable without restriction.

For European organizations, the primary risk from this phishing campaign is the potential compromise of user credentials or sensitive information through deception. Phishing attacks can lead to unauthorized access to corporate networks, data breaches, financial fraud, and subsequent reputational damage. Given the distributed nature of the phishing domains, organizations may find it challenging to block all malicious URLs promptly. The low severity rating suggests limited current impact, but phishing remains a common vector for initial compromise in targeted attacks. European entities with large user bases, especially those in finance, government, and critical infrastructure sectors, are at risk if users are not adequately trained or if email filtering and web security controls are insufficient. The compromised infrastructure indicates attackers may be leveraging hijacked resources, which can complicate attribution and takedown efforts, potentially prolonging exposure.

To mitigate this threat, European organizations should implement advanced email filtering solutions that incorporate real-time URL analysis and reputation scoring to detect and block phishing emails containing these domains. Deploying web proxy or DNS filtering to block access to known malicious domains and IP addresses is critical. Regularly updating threat intelligence feeds with OSINT data from trusted sources like CIRCL can enhance detection capabilities. User awareness training focused on recognizing phishing attempts and reporting suspicious emails is essential to reduce successful compromises. Multi-factor authentication (MFA) should be enforced to limit the impact of credential theft. Incident response teams should monitor for any signs of compromise linked to these domains and coordinate with hosting providers and law enforcement to facilitate takedown of malicious infrastructure. Additionally, organizations should conduct periodic phishing simulations to assess and improve user resilience against such campaigns.
