Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the RoundCube DOO breach identified under incident ID ROU1770638099.
The analysis begins with a detailed overview of RoundCube DOO's information like the linkedin page: https://www.linkedin.com/company/roundcubedoo, the number of followers: 163, the industry type: Software Development and the number of employees: 10 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 745 with a difference of -5 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 RoundCube DOO and their customers.
On 08 February 2026, Roundcube disclosed Privacy Bypass issues under the banner "Roundcube Patches Critical Privacy Bypass Vulnerability in Webmail Software".
Roundcube released urgent security updates to fix a privacy bypass flaw that allowed attackers to track email opens despite user settings blocking remote images.
The disruption is felt across the environment, affecting Roundcube webmail software (versions prior to 1.5.13 and 1.6.x before 1.6.13), and exposing Email open tracking, IP addresses, browser/device fingerprints.
In response, moved swiftly to contain the threat with measures like Security patch released (commit 26d7677), and began remediation that includes Upgrade to Roundcube 1.5.13 or 1.6.13, and stakeholders are being briefed through Public disclosure and advisory to administrators.
The case underscores how Resolved (Patch Released), teams are taking away lessons such as Need for stricter HTML sanitization in email clients, especially for SVG elements that can bypass image-blocking policies, and recommending next steps like Administrators should immediately upgrade to Roundcube 1.5.13 or 1.6.13. Users should avoid opening emails from untrusted sources until patched, with advisories going out to stakeholders covering Advisory to self-hosted Roundcube administrators to apply the patch.
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 moderate to high confidence (80%), supported by evidence indicating embed invisible 1x1 SVGs in emails, triggering automatic GET requests. Under the Reconnaissance tactic, the analysis identified Phishing for Information: Spearphishing Link (T1598.003) with high confidence (90%), supported by evidence indicating confirm active email addresses, log recipients’ IP addresses, fingerprint browsers. Under the Collection tactic, the analysis identified Automated Collection (T1119) with moderate to high confidence (80%), supported by evidence indicating triggering automatic GET requests to attacker-controlled servers when the email was rendered and Data Staged: Local Data Staging (T1074.001) with moderate to high confidence (70%), supported by evidence indicating email open tracking, IP addresses, browser/device fingerprints compromised. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with moderate to high confidence (80%), supported by evidence indicating gET requests to attacker-controlled servers. Under the Defense Evasion tactic, the analysis identified Obfuscated Files or Information: HTML Smuggling (T1027.006) with high confidence (90%), supported by evidence indicating flaw in HTML sanitizer...failed to recognize the SVG element <feImage> as an image container. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
