Full Incident Analysis Transcript

In this Rankiteo incident briefing, we review the Threema breach identified under incident ID THRNIN1786904641.

The analysis begins with a detailed overview of Threema's information like the linkedin page: https://www.linkedin.com/company/threema, the number of followers: 14942, the industry type: Software Development and the number of employees: 55 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 751 and after the incident was 733 with a difference of -18 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 Threema and their customers.

On 14 November 2023, Threema disclosed DDoS issues under the banner "Threema Hit by Persistent DDoS Attacks, Causing Widespread Service Disruptions".

Threema, the Swiss-based end-to-end encrypted messaging service, suffered a series of large-scale distributed denial-of-service (DDoS) attacks that disrupted user communications.

The disruption is felt across the environment, affecting Messaging service infrastructure.

In response, moved swiftly to contain the threat with measures like Additional DDoS protection measures to filter malicious traffic upstream, and began remediation that includes Reducing strain on infrastructure, and stakeholders are being briefed through Status page updates and email notifications to business users.

The case underscores how Ongoing, teams are taking away lessons such as DDoS attacks can be unusually persistent and adaptive, requiring dynamic mitigation strategies, and recommending next steps like Implement robust DDoS protection measures and upstream traffic filtering to mitigate future attacks, with advisories going out to stakeholders covering Business users of Threema Work were notified via email about unstable conditions.

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 Impact tactic, the analysis identified Network Denial of Service (T1498) with high confidence (95%), with evidence including large-scale distributed denial-of-service (DDoS) attacks, and intermittent outages across multiple regions and Direct Network Flood (T1498.001) with high confidence (90%), with evidence including dDoS attacks...disrupted user communications, and constantly shifting tactics to bypass mitigation efforts. Under the Defense Evasion tactic, the analysis identified Valid Accounts (T1078) with moderate confidence (50%), supported by evidence indicating threat actors constantly shifting tactics to bypass mitigation efforts and Protocol Tunneling (T1572) with lower confidence (40%), supported by evidence indicating adaptive strategies...to bypass mitigation efforts. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
