Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the Xerox breach identified under incident ID YAMXER1769102615.
The analysis begins with a detailed overview of Xerox's information like the linkedin page: https://www.linkedin.com/company/xerox, the number of followers: 957005, the industry type: Business Consulting and Services and the number of employees: 54786 employees
After the initial compromise, the video explains how Rankiteo's incident engine converts technical details into a normalized incident score. The incident score before the incident was 750 and after the incident was 638 with a difference of -112 which is could be a good indicator of the severity and impact of the incident.
In the next step of the video, we will analyze in more details the incident and the impact it had on Xerox and their customers.
A newly reported cybersecurity incident, "INC Ransomware Gang’s Security Failure Exposes Stolen Data from 12 U.S. Organizations", has drawn attention.
Researchers at Cyber Centaurs uncovered data exfiltrated by the INC ransomware gang from 12 U.S.
The disruption is felt across the environment, and exposing Stolen data from 12 organizations.
Formal response steps have not been shared publicly yet.
The case underscores how Ongoing (coordination with law enforcement), teams are taking away lessons such as The incident highlights the risks of reused attacker infrastructure and the potential for recovering stolen data even after an attack concludes, and recommending next steps like Defenders should monitor for Restic or its renamed variants in suspicious locations using YARA and Sigma rules to detect early-stage ransomware activity.
Finally, we try to match the incident with the MITRE ATT&CK framework to see if there is any correlation between the incident and the MITRE ATT&CK framework.
The MITRE ATT&CK framework is a knowledge base of techniques and sub-techniques that are used to describe the tactics and procedures of cyber adversaries. It is a powerful tool for understanding the threat landscape and for developing effective defense strategies.
MITRE ATT&CK® Correlation Analysis
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 Valid Accounts (T1078) with moderate confidence (60%), supported by evidence indicating hardcoded credentials...revealed a pattern of long-term data retention and Phishing: Spearphishing Attachment (T1566.001) with lower confidence (40%), supported by evidence indicating base64-encoded ‘new.ps1’ file found in PowerShell scripts. Under the Execution tactic, the analysis identified Command and Scripting Interpreter: PowerShell (T1059.001) with high confidence (90%), supported by evidence indicating powerShell scripts (including a Base64-encoded ‘new.ps1’ file) and User Execution: Malicious File (T1204.002) with moderate to high confidence (70%), supported by evidence indicating rainINC variant was deployed via the PerfLogs directory. Under the Persistence tactic, the analysis identified Valid Accounts (T1078) with moderate to high confidence (70%), supported by evidence indicating hardcoded credentials...reused Restic-based storage repositories. Under the Privilege Escalation tactic, the analysis identified Valid Accounts (T1078) with moderate confidence (60%), supported by evidence indicating hardcoded credentials...revealed a pattern of long-term data retention. Under the Defense Evasion tactic, the analysis identified Masquerading: Match Legitimate Name or Location (T1036.005) with moderate to high confidence (80%), supported by evidence indicating legitimate backup tool Restic used by INC gang for data exfiltration, Indicator Removal: File Deletion (T1070.004) with moderate to high confidence (70%), supported by evidence indicating cleanup utilities...included in the gang’s broader toolkit, and Hide Artifacts: Hidden Files and Directories (T1564.001) with moderate to high confidence (80%), supported by evidence indicating rainINC variant deployed via the PerfLogs directory (abused for staging). Under the Credential Access tactic, the analysis identified OS Credential Dumping (T1003) with moderate confidence (50%), supported by evidence indicating hardcoded credentials...revealed during forensic analysis and Unsecured Credentials: Credentials In Files (T1552.001) with moderate to high confidence (80%), supported by evidence indicating hardcoded credentials found in backup commands and scripts. Under the Discovery tactic, the analysis identified Network Service Discovery (T1046) with moderate to high confidence (70%), supported by evidence indicating network scanners included in the gang’s broader toolkit.

Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (90%), supported by evidence indicating stolen data from 12 U.S. organizations across multiple sectors and Data from Cloud Storage (T1530) with moderate confidence (60%), supported by evidence indicating restic-based storage repositories reused across campaigns. Under the Command and Control tactic, the analysis identified Application Layer Protocol: Web Protocols (T1071.001) with moderate to high confidence (70%), supported by evidence indicating restic used for backup commands (implies C2 communication). Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with high confidence (90%), supported by evidence indicating data exfiltrated by the INC ransomware gang from 12 organizations and Exfiltration Over Web Service: Exfiltration to Cloud Storage (T1567.002) with moderate to high confidence (70%), supported by evidence indicating restic-based storage repositories reused for data retention. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with high confidence (90%), supported by evidence indicating rainINC variant deployed; data encryption confirmed and Inhibit System Recovery (T1490) with moderate confidence (60%), supported by evidence indicating ransomware-as-a-service (RaaS) operation targeting high-profile victims. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
