D-Link Breach Incident Score: Analysis & Impact (DLI1767786327)

In this Rankiteo incident briefing, we review the D-Link breach identified under incident ID DLI1767786327.

The analysis begins with a detailed overview of D-Link's information like the linkedin page: https://www.linkedin.com/company/dlink-corp, the number of followers: 12466, the industry type: Information Technology & Services and the number of employees: 528 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 758 and after the incident was 753 with a difference of -5 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 D-Link and their customers.

On 01 December 2016, D-Link disclosed DNS Hijacking and Unauthenticated Command Injection issues under the banner "D-Link Router Unauthenticated Command Injection and DNS Hijacking Vulnerabilities".

D-Link has confirmed unauthenticated command injection vulnerabilities affecting multiple router models deployed internationally.

The disruption is felt across the environment, affecting Multiple D-Link router models.

In response, moved swiftly to contain the threat with measures like Factory resets, Unique administrative passwords and Manual DNS configuration using trusted providers, and began remediation that includes Official firmware patches from regional carriers and Manual DNS configuration, and stakeholders are being briefed through Public advisories via Google News, LinkedIn, and X.

The case underscores how Ongoing, teams are taking away lessons such as Importance of input validation in web interfaces and secure DNS configuration to prevent hijacking, and recommending next steps like Perform factory resets on affected routers, Establish unique administrative passwords and Manually configure DNS settings using trusted providers (e.g., Google DNS or Cloudflare DNS), with advisories going out to stakeholders covering Follow D-Link on Google News, LinkedIn, and X for updates.

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 Exploit Public-Facing Application (T1190) with high confidence (90%), supported by evidence indicating critical unauthenticated command injection vulnerabilities in multiple router models. Under the Execution tactic, the analysis identified Command and Scripting Interpreter (T1059) with high confidence (90%), supported by evidence indicating enabling attackers to remotely modify DNS settings without authentication. Under the Persistence tactic, the analysis identified Account Manipulation (T1098) with moderate to high confidence (70%), supported by evidence indicating permitting attackers to alter DNS configurations persistently. Under the Defense Evasion tactic, the analysis identified Impair Defenses: Disable or Modify Tools (T1562.001) with moderate to high confidence (80%), supported by evidence indicating improper input validation in the routers’ web interfaces. Under the Credential Access tactic, the analysis identified Brute Force: Password Guessing (T1110.001) with moderate confidence (60%), supported by evidence indicating unauthenticated access to critical network settings. Under the Collection tactic, the analysis identified Data from Information Repositories (T1213) with moderate to high confidence (70%), supported by evidence indicating traffic interception facilitating malware distribution, phishing. Under the Command and Control tactic, the analysis identified Application Layer Protocol: Web Protocols (T1071.001) with moderate to high confidence (80%), supported by evidence indicating attackers leveraged Google Cloud Platform to deploy the DNSChanger malware and Dynamic Resolution: Domain Generation Algorithms (T1568.002) with moderate to high confidence (70%), supported by evidence indicating redirect user traffic to malicious infrastructure. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with moderate to high confidence (80%), supported by evidence indicating traffic interception facilitating...phishing and traffic interception. Under the Impact tactic, the analysis identified Network Denial of Service (T1498) with moderate confidence (60%), supported by evidence indicating redirecting user traffic to malicious infrastructure and Data Manipulation: Transmitted Data Manipulation (T1565.002) with high confidence (90%), supported by evidence indicating remotely modify DNS settings...redirect user traffic to malicious infrastructure. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
