IBM Breach Incident Score: Analysis & Impact (IBM3762037111125)

In this Rankiteo incident briefing, we review the IBM breach identified under incident ID IBM3762037111125.

The analysis begins with a detailed overview of IBM's information like the linkedin page: https://www.linkedin.com/company/ibm, the number of followers: 18639680, the industry type: IT Services and IT Consulting and the number of employees: 332876 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 792 and after the incident was 762 with a difference of -30 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 IBM and their customers.

IBM recently reported "an incident", a noteworthy cybersecurity incident.

A 403 Forbidden error was encountered when attempting to access an IBM page.

The disruption is felt across the environment, affecting IBM webpage (unspecified).

In response, and began remediation that includes verify URL correctness, check access permissions and review WAF/ACL rules, while recovery efforts such as restore access via IT support and update security policies if misconfigured continue.

The case underscores how unconfirmed (could be a false positive or legitimate access restriction), and recommending next steps like Implement proper error handling for 403 pages to avoid confusion with security incidents, Review access control lists (ACLs) and web application firewall (WAF) rules to prevent false positives and Ensure clear communication channels for users encountering access issues.

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 Reconnaissance tactic, the analysis identified Active Scanning: Vulnerability Scanning (T1595.001) with moderate to high confidence (70%), with evidence including 403 Forbidden error ... could allow attackers to probe deeper into IBM’s infrastructure, and potential access control vulnerability or unintended exposure of internal systems and Gather Victim Host Information (T1592) with moderate confidence (60%), supported by evidence indicating probing deeper into IBM’s infrastructure via misconfigured access controls. Under the Initial Access tactic, the analysis identified Exploit Public-Facing Application (T1190) with moderate to high confidence (80%), with evidence including access control vulnerability or unintended exposure of internal systems, and misconfigured security restriction leading to 403 errors and Valid Accounts (T1078) with moderate confidence (50%), supported by evidence indicating authentication failure as a possible cause of 403 errors. Under the Defense Evasion tactic, the analysis identified Data from Local System (T1005) with moderate confidence (50%), supported by evidence indicating review WAF/ACL rules suggests attackers might bypass security controls. Under the Credential Access tactic, the analysis identified Brute Force (T1110) with lower confidence (40%), supported by evidence indicating could escalate into ... credential stuffing if access flaws are exploited. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
