Incident Score: Analysis & Impact (CONDAVORASANASA1770645741)

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%), supported by evidence indicating oracle zero-day vulnerability exploited in Clop attack on University of Phoenix, External Remote Services (T1133) with moderate to high confidence (70%), supported by evidence indicating manufacturing sector surge suggests exploitation of remote access services, and Phishing: Spearphishing Attachment (T1566.001) with moderate confidence (60%), supported by evidence indicating ransomware groups like Qilin and Akira commonly use phishing for initial access. Under the Execution tactic, the analysis identified User Execution: Malicious File (T1204.002) with moderate to high confidence (80%), supported by evidence indicating ransomware strains (Qilin, Akira) typically require user execution of malicious payloads and Command and Scripting Interpreter: PowerShell (T1059.001) with moderate to high confidence (70%), supported by evidence indicating common ransomware tactic for post-exploitation execution. Under the Persistence tactic, the analysis identified Valid Accounts (T1078) with moderate to high confidence (80%), supported by evidence indicating ransomware groups maintain persistence via compromised credentials and Create or Modify System Process: Windows Service (T1543.003) with moderate confidence (60%), supported by evidence indicating ransomware often installs services for persistence. Under the Privilege Escalation tactic, the analysis identified Exploitation for Privilege Escalation (T1068) with moderate to high confidence (70%), supported by evidence indicating zero-day exploits (Oracle) suggest privilege escalation attempts and Valid Accounts (T1078) with moderate to high confidence (80%), supported by evidence indicating compromised accounts used for lateral movement and privilege escalation. Under the Defense Evasion tactic, the analysis identified Obfuscated Files or Information (T1027) with moderate to high confidence (80%), supported by evidence indicating ransomware payloads are typically obfuscated to evade detection and Impair Defenses: Disable or Modify Tools (T1562.001) with moderate to high confidence (70%), supported by evidence indicating ransomware often disables security tools to evade detection. Under the Credential Access tactic, the analysis identified OS Credential Dumping (T1003) with moderate to high confidence (80%), supported by evidence indicating ransomware groups dump credentials for lateral movement and privilege escalation and Credentials from Password Stores (T1555) with moderate to high confidence (70%), supported by evidence indicating common tactic in ransomware attacks to access stored credentials. Under the Discovery tactic, the analysis identified Account Discovery (T1087) with moderate to high confidence (70%), supported by evidence indicating ransomware groups enumerate accounts for lateral movement and File and Directory Discovery (T1083) with moderate to high confidence (80%), supported by evidence indicating ransomware scans for high-value data prior to exfiltration. Under the Lateral Movement tactic, the analysis identified Remote Services: Remote Desktop Protocol (T1021.001) with moderate to high confidence (80%), supported by evidence indicating ransomware groups use RDP for lateral movement and Valid Accounts (T1078) with high confidence (90%), supported by evidence indicating compromised credentials used for lateral movement across networks. Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (90%), supported by evidence indicating 59.2M records compromised, 31.2 petabytes exfiltrated by Qilin and Data from Network Shared Drive (T1039) with moderate to high confidence (80%), supported by evidence indicating ransomware groups target shared drives for data collection. Under the Command and Control tactic, the analysis identified Application Layer Protocol: Web Protocols (T1071.001) with moderate to high confidence (80%), supported by evidence indicating ransomware groups use HTTP/HTTPS for C2 communications and Ingress Tool Transfer (T1105) with moderate to high confidence (70%), supported by evidence indicating ransomware payloads and tools downloaded via C2 channels. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with high confidence (90%), supported by evidence indicating 31.2 petabytes exfiltrated by Qilin, 8.5TB by SafePay (Conduent) and Exfiltration Over Web Service: Exfiltration to Cloud Storage (T1567.002) with moderate confidence (60%), supported by evidence indicating ransomware groups may use cloud storage for data exfiltration. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with high confidence (90%), supported by evidence indicating ransomware attacks encrypt data for financial gain, Data Destruction (T1485) with moderate confidence (50%), supported by evidence indicating potential data destruction if ransom demands are not met, and Inhibit System Recovery (T1490) with moderate to high confidence (70%), supported by evidence indicating ransomware often deletes backups to prevent recovery. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
