Atlassian Breach Incident Score: Analysis & Impact (CANADYATLHUBEPIMODGAMZOOWEWHALBETSONTEL1769527593)

In this Rankiteo incident briefing, we review the Atlassian breach identified under incident ID CANADYATLHUBEPIMODGAMZOOWEWHALBETSONTEL1769527593.

The analysis begins with a detailed overview of Atlassian's information like the linkedin page: https://www.linkedin.com/company/atlassian, the number of followers: 2347080, the industry type: Software Development and the number of employees: 21511 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 754 and after the incident was 731 with a difference of -23 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 Atlassian and their customers.

Atlassian recently reported "ShinyHunters-Linked Cybercrime Campaign Targets Over 100 Major Organizations", a noteworthy cybersecurity incident.

A recent cybercrime campaign attributed to the ShinyHunters group has targeted at least 100 organizations across multiple sectors, including software, finance, healthcare, and energy.

The disruption is felt across the environment, affecting SSO accounts (Okta and other identity platforms), and exposing Millions of records allegedly stolen, with nearly Millions (alleged) records at risk.

Formal response steps have not been shared publicly yet.

The case underscores how Ongoing (infrastructure identified, breach success unclear).

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.

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: Vishing (T1566.004) with high confidence (95%), with evidence including attackers employed voice phishing (vishing) tactics, and using specialized phishing kits and Acquire Infrastructure: Domains (T1583.001) with high confidence (90%), supported by evidence indicating threat actors registered fake domains impersonating high-profile companies. Under the Credential Access tactic, the analysis identified Brute Force: Password Guessing (T1110.001) with moderate to high confidence (70%), supported by evidence indicating intercepted credentials and manipulated victims into bypassing MFA, Modify Authentication Process: Multi-Factor Authentication (T1556.006) with high confidence (90%), supported by evidence indicating manipulated victims into bypassing multi-factor authentication (MFA) by convincing them to approve push notifications or submit OTPs, and Valid Accounts: Cloud Accounts (T1078.004) with high confidence (95%), supported by evidence indicating compromise single sign-on (SSO) accounts, particularly those using Okta. Under the Defense Evasion tactic, the analysis identified Use Alternate Authentication Material: Web Session Cookie (T1550.004) with moderate to high confidence (80%), supported by evidence indicating real-time session orchestration, where threat actors guided victims through the authentication process and Multi-Factor Authentication Request Generation (T1621) with high confidence (90%), supported by evidence indicating manipulated victims into bypassing MFA by convincing them to approve push notifications. Under the Collection tactic, the analysis identified Data from Information Repositories: Code Repositories (T1213.003) with moderate to high confidence (70%), supported by evidence indicating allegedly stole millions of records from companies like Betterment, Crunchbase, and SoundCloud and Data from Local System (T1005) with moderate to high confidence (80%), supported by evidence indicating personally Identifiable Information (PII), Credentials, Business Data compromised. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with moderate to high confidence (85%), with evidence including data sold on dark web, and millions of records allegedly stolen. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
