Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the NATO breach identified under incident ID NAT1773851315.
The analysis begins with a detailed overview of NATO's information like the linkedin page: https://www.linkedin.com/company/nato, the number of followers: 0, the industry type: International Affairs and the number of employees: 9204 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 834 and after the incident was 826 with a difference of -8 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 NATO and their customers.
On 13 January 2026, Ukraine’s regional prosecutors disclosed Cyberespionage issues under the banner "FancyBear’s Major OpSec Blunder Exposes Espionage Campaign Targeting European Governments and NATO".
In a rare operational security failure, Russian state-linked hacking group FancyBear (APT28/Forest Blizzard/GRU Unit 26165) inadvertently exposed a long-running cyberespionage campaign after leaving a server unsecured for over 500 days.
The disruption is felt across the environment, affecting Government and military email systems (Roundcube webmail), NATO infrastructure, and exposing 2,800 exfiltrated government and military emails, 240 stolen credentials (including passwords and TOTP 2FA secrets), 140 silent email-forwarding rules, 11,500 harvested contact addresses, with nearly 2,800 emails, 240 credentials, 11,500 contact addresses records at risk.
Formal response steps have not been shared publicly yet.
The case underscores how Ongoing (exposed data analyzed by researchers), teams are taking away lessons such as FancyBear’s persistent reliance on known infrastructure despite prior attribution; sophistication of 2FA bypass techniques; risks of unsecured servers in state-sponsored campaigns, and recommending next steps like Immediate revocation of compromised credentials and TOTP secrets; patching Roundcube XSS vulnerabilities; enhanced monitoring of email systems; network segmentation for sensitive government/military infrastructure; regular audits of third-party VPS security.
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 Exploit Public-Facing Application (T1190) with high confidence (90%), with evidence including roundcube webmail XSS vulnerability, and exploitation of Roundcube webmail XSS vulnerability and External Remote Services (T1133) with moderate to high confidence (80%), supported by evidence indicating exposed server (unsecured VPS) hosted at IP 203.161.50.145. Under the Execution tactic, the analysis identified Exploitation for Client Execution (T1203) with high confidence (90%), supported by evidence indicating javaScript module (keyTwoAuth.js) exploited Roundcube XSS vulnerability and JavaScript (T1059.007) with high confidence (90%), supported by evidence indicating javaScript payloads (XSS vulnerability in Roundcube webmail). Under the Credential Access tactic, the analysis identified Credentials from Web Browsers (T1555.003) with high confidence (90%), supported by evidence indicating 240 stolen credentials (including passwords and TOTP 2FA secrets), Credentials In Files (T1552.005) with moderate to high confidence (80%), supported by evidence indicating exfiltrated emails and credentials stored on exposed server, and Multi-Factor Authentication Interception (T1556.003) with high confidence (95%), supported by evidence indicating javaScript module parsed twofactorgauthenticator plugin settings to steal TOTP secrets. Under the Collection tactic, the analysis identified Email Collection: Remote Email Collection (T1114.002) with high confidence (90%), supported by evidence indicating 2,800 exfiltrated government and military emails, Data from Local System (T1005) with moderate to high confidence (80%), supported by evidence indicating 11,500 harvested contact addresses from victims, and Email Collection: Email Forwarding Rule (T1114.003) with high confidence (90%), supported by evidence indicating 140 silent email-forwarding rules discovered. Under the Command and Control tactic, the analysis identified Application Layer Protocol: Web Protocols (T1071.001) with high confidence (90%), supported by evidence indicating exfiltrated data sent to C2 server (zhblz.com) under log prefix ktfu and Proxy: External Proxy (T1090.002) with moderate to high confidence (70%), supported by evidence indicating nameCheap VPS used as C2 infrastructure. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with high confidence (95%), supported by evidence indicating 2,800 emails, 240 credentials, 11,500 contacts exfiltrated to zhblz.com and Exfiltration Over Web Service: Exfiltration to Cloud Storage (T1567.002) with moderate to high confidence (70%), supported by evidence indicating data stored on exposed NameCheap VPS (203.161.50.145). Under the Defense Evasion tactic, the analysis identified Hide Artifacts: Hidden Window (T1564.003) with moderate to high confidence (80%), supported by evidence indicating silent email-forwarding rules (140 discovered), Valid Accounts: Cloud Accounts (T1078.004) with high confidence (90%), supported by evidence indicating stolen credentials (240) including TOTP secrets for authenticated sessions, and Ingress Tool Transfer (T1105) with moderate to high confidence (70%), supported by evidence indicating javaScript payloads delivered via XSS vulnerability. Under the Persistence tactic, the analysis identified Office Application Startup: Office Test (T1137.002) with moderate to high confidence (70%), supported by evidence indicating 140 silent email-forwarding rules for persistent access and Account Manipulation: Additional Cloud Credentials (T1098.001) with moderate to high confidence (80%), supported by evidence indicating tOTP secrets and recovery codes compromised for 256 accounts. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
