This threat involves a targeted phishing campaign against Ukrainian users, specifically impersonating the National Police of Ukraine to increase credibility and lure victims into opening malicious attachments. The attackers use fileless techniques by embedding malicious code within Scalable Vector Graphics (SVG) files, which are often overlooked by traditional antivirus solutions. Upon execution, these SVG files deploy two types of malware: Amatera Stealer, which is designed to exfiltrate sensitive information such as credentials and system data, and PureMiner, a cryptocurrency mining malware that exploits system resources for illicit mining activities. The use of fileless methods complicates detection and remediation, as no traditional executable files are dropped on disk. The campaign is geographically focused on Kyiv but could potentially spread or inspire similar attacks elsewhere. The attackers exploit social engineering by leveraging the trust associated with the National Police, increasing the likelihood of victim interaction. Although no known exploits in the wild have been reported beyond this campaign, the dual impact on confidentiality (via credential theft) and availability (via resource exhaustion from mining) presents a significant risk. The absence of affected software versions or patches indicates this is primarily a social engineering and malware delivery threat rather than a software vulnerability. The medium severity rating reflects the balance between the attack's sophistication and its limited scope.

For European organizations, especially those with business or operational ties to Ukraine, this threat poses risks of credential compromise and resource depletion. Credential theft can lead to unauthorized access to sensitive systems, data breaches, and lateral movement within networks. The presence of PureMiner can degrade system performance, increase energy costs, and potentially cause hardware damage due to prolonged high resource usage. Organizations involved in law enforcement, government, or sectors interacting with Ukrainian entities may be targeted or indirectly affected. The fileless nature of the attack complicates detection, increasing the risk of prolonged undetected compromise. Additionally, the use of trusted institutional impersonation may lower user suspicion, increasing the likelihood of successful phishing. European organizations with remote workers or partners in Ukraine should be particularly cautious. The campaign also highlights the evolving sophistication of phishing attacks, emphasizing the need for advanced detection and response capabilities.

1. Implement advanced email filtering solutions capable of detecting and blocking malicious SVG files and other fileless attack vectors. 2. Conduct targeted user awareness training focusing on phishing threats that impersonate trusted institutions, emphasizing verification of unexpected communications from law enforcement or government entities. 3. Deploy endpoint detection and response (EDR) tools that monitor for anomalous behaviors associated with fileless malware, such as unusual script execution or network connections. 4. Restrict or monitor the use of SVG files in email attachments and web content, applying strict content inspection policies. 5. Enforce multi-factor authentication (MFA) across all critical systems to reduce the impact of credential theft. 6. Maintain up-to-date threat intelligence feeds to identify emerging phishing campaigns and indicators of compromise. 7. Establish incident response procedures specifically for fileless malware infections, including memory analysis and network traffic inspection. 8. Collaborate with Ukrainian and European law enforcement agencies to share information and receive alerts about ongoing campaigns. 9. Regularly audit and review user privileges to limit the potential damage from compromised accounts.
