IBM Breach Incident Score: Analysis & Impact (IBM4803148111325)

In this Rankiteo incident briefing, we review the IBM breach identified under incident ID IBM4803148111325.

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 unspecified_IBM_web_page.

In response, and began remediation that includes verify URL correctness, check case sensitivity and review access permissions, while recovery efforts such as restore access via permission adjustments, update WAF rules if misconfigured and communicate resolution to affected users continue, and stakeholders are being briefed through suggested actions provided to end-users (e.g., verify URL, visit IBM homepage).

The case underscores how unconfirmed (could be benign access issue or security-related), and recommending next steps like Implement user-friendly error pages with clear guidance for 403/404 errors, Review WAF/access control rules to minimize false positives and Monitor for patterns of unauthorized access attempts, with advisories going out to stakeholders covering Users were advised to verify URL spelling, check case sensitivity, or visit the IBM homepage.

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 (T1595.002) with moderate to high confidence (70%), with evidence including probing attack by malicious actors in description, and incident Number (18.6e3f655f.1762993875.3f8d8f64) exposure aiding reconnaissance. Under the Initial Access tactic, the analysis identified Exploit Public-Facing Application (T1190) with moderate confidence (60%), with evidence including 403 Forbidden error on IBM web page suggests probing for misconfigurations, and wAF blocking, IP restriction, or authentication failure as potential triggers. Under the Defense Evasion tactic, the analysis identified Data from Local System (T1005) with moderate confidence (50%), supported by evidence indicating incident Number (18.6e3f655f.1762993875.3f8d8f64) exposed via error message. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
