The detection rule identifies DNS queries directed toward the domain "ufile.io", which has been reported to be misused by various malware strains and threat actors for the purposes of exfiltrating data from compromised systems. By monitoring for DNS queries that contain this specific string, organizations can potentially flag suspicious activity related to data leakage or lateral movement involving this domain. The rule was created following incidents where ufile.io was linked to ransomware operations, notably in the case of Diavol ransomware, highlighting its relevance in contemporary cyber threat landscapes. While the rule is set to a 'low' alert level, it emphasizes the need for further investigation, as DNS queries for ufile.io are not inherently malicious and may arise from legitimate activities. Users are advised to review the context of these queries to ascertain appropriate measures before taking action against detected instances.
