Full Incident Analysis Transcript

In this Rankiteo incident briefing, we review the Mastodon breach identified under incident ID JOIBLU1776719420.

The analysis begins with a detailed overview of Mastodon's information like the linkedin page: https://www.linkedin.com/company/joinmastodon, the number of followers: 10199, the industry type: Social Networking Platforms and the number of employees: 23 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 753 and after the incident was 733 with a difference of -20 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 Mastodon and their customers.

On 17 April 2023, Mastodon (mastodon.social) disclosed DDoS issues under the banner "Mastodon’s Flagship Server Hit by DDoS Attack, Causing Temporary Outages".

Mastodon’s primary server, *mastodon.social*, was targeted by a distributed denial-of-service (DDoS) attack on Monday, rendering the instance intermittently inaccessible.

The disruption is felt across the environment, affecting mastodon.social server.

In response, teams activated the incident response plan, moved swiftly to contain the threat with measures like Countermeasures implemented to mitigate the attack, while recovery efforts such as Access restored by 09:05 ET continue, and stakeholders are being briefed through Status update acknowledging the attack and progress.

The case underscores how Resolved, teams are taking away lessons such as Decentralized networks like Mastodon are resilient to DDoS attacks, as only specific instances are affected rather than the entire network, with advisories going out to stakeholders covering Users informed via status updates about the outage and resolution.

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 dDoS attack involving millions of malicious requests, and rendering the instance intermittently inaccessible and Direct Network Flood (T1498.001) with high confidence (90%), supported by evidence indicating millions of malicious requests, consistent with a DDoS pattern. Under the Initial Access tactic, the analysis identified Exploit Public-Facing Application (T1190) with moderate confidence (50%), supported by evidence indicating mastodon’s primary server, *mastodon.social*, was targeted. Under the Defense Evasion tactic, the analysis identified Network Denial of Service (T1498) with moderate to high confidence (70%), supported by evidence indicating attack overwhelmed servers with junk traffic, causing outages. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
