Incident Score: Analysis & Impact (IVASONCIS1776702475)

Rankiteo's analysis has identified several MITRE ATT&CK tactics and techniques associated with this incident, each with varying levels of confidence based on available evidence. Under the Reconnaissance tactic, the analysis identified Active Scanning (T1595) with high confidence (90%), with evidence including scanning activity was widely dispersed, and broad reconnaissance targeting specific products and Active Scanning: Vulnerability Scanning (T1595.002) with moderate to high confidence (80%), supported by evidence indicating nearly half of all scanning and exploitation surges targeting specific products. Under the Initial Access tactic, the analysis identified Exploit Public-Facing Application (T1190) with high confidence (90%), with evidence including exploiting software vulnerabilities before vendors publicly disclose them, and high-severity flaws generated the most probing activity and External Remote Services (T1133) with moderate to high confidence (70%), with evidence including remote Code Execution (RCE) probes detected, and targeted exploitation of Cisco, Juniper, SonicWall, Ivanti. Under the Execution tactic, the analysis identified Exploitation for Client Execution (T1203) with moderate to high confidence (80%), with evidence including remote Code Execution (RCE) probes, and exploitation detected up to 39 days before disclosure. Under the Credential Access tactic, the analysis identified Brute Force (T1110) with moderate to high confidence (80%), with evidence including 56% of brute-force attempts preceded public CVEs, and brute-force and RCE probes were more concentrated. Under the Discovery tactic, the analysis identified Network Service Discovery (T1046) with moderate to high confidence (70%), supported by evidence indicating scanning activity was widely dispersed with many IP addresses conducting sessions. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with moderate confidence (60%), with evidence including motivation includes data exfiltration, and targeted attacks on critical infrastructure vendors. Under the Impact tactic, the analysis identified Endpoint Denial of Service (T1499) with moderate confidence (50%), with evidence including exploitation of high-severity flaws, and attack with significant impact with customers data leaks. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
