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 Initial Access tactic, the analysis identified Exploit Public-Facing Application (T1190) with high confidence (90%), with evidence including high-severity flaws generated the most probing activity, and rCE probes targeting undisclosed vulnerabilities and External Remote Services (T1133) with moderate to high confidence (80%), with evidence including exploitation of Cisco, Juniper, SonicWall, and Ivanti flaws, and brute-force attempts preceding disclosures. Under the Reconnaissance tactic, the analysis identified Active Scanning (T1595) with high confidence (95%), with evidence including scanning activity widely dispersed with many IPs conducting sessions, and nearly half of scanning surges led to vulnerability disclosures and Active Scanning: Vulnerability Scanning (T1595.002) with high confidence (90%), with evidence including 57% of scanning events led to disclosures, 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 (85%), with evidence including 56% of brute-force attempts preceded public CVEs, and later-stage attacks concentrated with high session volumes. 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 targeting undisclosed flaws, and shift from reconnaissance to focused attacks. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with moderate to high confidence (70%), with evidence including motivation includes data exfiltration, and targeted attacks on critical infrastructure vendors. Under the Defense Evasion tactic, the analysis identified Exploitation for Defense Evasion (T1211) with moderate to high confidence (75%), with evidence including exploitation of undisclosed vulnerabilities before patches available, and attackers shift behavior as vulnerabilities near disclosure. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
