Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the Xerox breach identified under incident ID XERTEX1781864792.
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 567 and after the incident was 396 with a difference of -171 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.
NHS Scotland recently reported "INC Ransomware Emerges as a Dominant Threat, Targeting 800+ Victims Since 2023", a noteworthy cybersecurity incident.
INC ransomware has rapidly evolved into one of the most active ransomware families of 2026, compromising over 800 organizations since 2023.
The disruption is felt across the environment, affecting Windows and Linux/ESXi, and exposing Yes.
Formal response steps have not been shared publicly yet.
The case underscores how teams are taking away lessons such as The evolution of INC ransomware underscores the adaptability of threat actors, combining technical refinement with aggressive extortion tactics to maximize impact. Organizations must prioritize patch management, credential security, and monitoring of RMM tools to mitigate such threats, and recommending next steps like Implement patch management for public-facing vulnerabilities (e.g., Citrix, Fortinet, SimpleHelp RMM), Enhance monitoring and segmentation of virtualized environments (ESXi/Linux) and Restrict use of native tools like RDP and PsExec for lateral movement.
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 Phishing: Spearphishing Attachment (T1566.001) with high confidence (90%), supported by evidence indicating initial access vectors include spear-phishing, Valid Accounts (T1078) with high confidence (90%), supported by evidence indicating purchased credentials used for initial access, and Exploit Public-Facing Application (T1190) with high confidence (90%), supported by evidence indicating exploitation of public-facing vulnerabilities (e.g., Citrix, Fortinet CVEs). Under the Execution tactic, the analysis identified Command and Scripting Interpreter: PowerShell (T1059.001) with moderate to high confidence (80%), supported by evidence indicating modified Veeam-Get-Creds.ps1 script used for credential dumping and User Execution: Malicious File (T1204.002) with moderate to high confidence (70%), supported by evidence indicating operator-driven execution with command-line arguments for ransomware. Under the Persistence tactic, the analysis identified Valid Accounts (T1078) with moderate to high confidence (80%), supported by evidence indicating purchased credentials used for persistence. Under the Privilege Escalation tactic, the analysis identified Valid Accounts (T1078) with moderate to high confidence (80%), supported by evidence indicating purchased credentials used for privilege escalation and OS Credential Dumping (T1003) with high confidence (90%), supported by evidence indicating credential dumping from Veeam backups using modified Veeam-Get-Creds.ps1. Under the Defense Evasion tactic, the analysis identified Obfuscated Files or Information (T1027) with high confidence (90%), supported by evidence indicating ransomware rewritten in Rust for cross-platform efficiency and obfuscation and Indicator Removal: File Deletion (T1070.004) with moderate to high confidence (70%), supported by evidence indicating hybrid cryptography with distinct footer signature appended to files. Under the Credential Access tactic, the analysis identified OS Credential Dumping (T1003) with high confidence (90%), supported by evidence indicating credential dumping from Veeam backups targeting salted DPAPI encryption and Credentials from Password Stores (T1555) with moderate to high confidence (80%), supported by evidence indicating modified Veeam-Get-Creds.ps1 script used to dump credentials. Under the Discovery tactic, the analysis identified Account Discovery (T1087) with moderate to high confidence (70%), supported by evidence indicating lateral movement relies on Angry IP Scanner and Network Service Discovery (T1046) with moderate to high confidence (70%), supported by evidence indicating angry IP Scanner used for network discovery. Under the Lateral Movement tactic, the analysis identified Remote Services: Remote Desktop Protocol (T1021.001) with high confidence (90%), supported by evidence indicating lateral movement relies on native tools (RDP), Remote Services: SMB/Windows Admin Shares (T1021.002) with moderate to high confidence (80%), supported by evidence indicating lateral movement via PsExec, and Account Discovery: Domain Account (T1087.002) with moderate to high confidence (70%), supported by evidence indicating angry IP Scanner used for account discovery. Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (90%), supported by evidence indicating data exfiltration via 7-Zip and rclone before encryption. 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 dual-site infrastructure such as private negotiation portal and public leak site. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with high confidence (90%), supported by evidence indicating data exfiltration via 7-Zip and rclone and Exfiltration Over Web Service: Exfiltration to Cloud Storage (T1567.002) with moderate to high confidence (70%), supported by evidence indicating rclone used for data exfiltration. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with high confidence (100%), supported by evidence indicating hybrid cryptography using Curve25519-derived keys and AES/Salsa20 for file encryption, Inhibit System Recovery (T1490) with high confidence (90%), supported by evidence indicating credential dumping from Veeam backups to disable recovery options, Service Stop (T1489) with moderate to high confidence (80%), supported by evidence indicating linux/ESXi-specific routines shut down VMs via vim-cmd, and Defacement: Internal Defacement (T1491.001) with moderate to high confidence (80%), supported by evidence indicating automated network printing of ransom notes. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
