Quick Review of Attack Tactics Covered in the Mobile Matrix

The MITRE ATT&CK Mobile Matrix encompasses a comprehensive range of tactics that adversaries employ to compromise mobile devices.

These tactics, which align with various stages of an attack lifecycle, provide a clear framework for understanding and mitigating potential threats.

• Initial Access: This tactic involves the ways adversaries gain a foothold on mobile devices. Common techniques include exploiting public-facing applications, spear-phishing, and the use of malicious apps or rogue profiles.

• Execution: This pertains to the methods used by attackers to execute malicious code on a mobile device. Techniques can involve exploiting vulnerabilities in trusted applications or the operating system.

• Persistence: Attackers use various techniques to maintain their foothold on a compromised device. These include manipulating account or device settings, exploiting mobile device management tools, or using stealthy malware that evades detection.

• Privilege Escalation: This tactic involves gaining higher-level permissions on the device, often by exploiting vulnerabilities or system misconfigurations, allowing deeper access and control.

• Defense Evasion: Adversaries use techniques to avoid detection, such as obfuscating malicious code, disabling security features, or mimicking legitimate applications.

• Credential Access: Techniques under this category focus on stealing user credentials, such as passwords, tokens, or keys, often through phishing, keylogging, or exploiting software vulnerabilities.

• Discovery: Here, attackers gather information about the device, network, and installed applications, which can be used to further the attack or prepare for subsequent stages.

• Lateral Movement: This involves moving across a network to reach more targets or gain access to more valuable data, often leveraging stolen credentials or exploiting vulnerabilities in network protocols.

• Collection: Attackers collect data of interest from the mobile device, which may include personal information, corporate data, or sensitive communications.

• Exfiltration: This tactic focuses on methods used to steal data from the compromised device, often through encrypted channels to avoid detection.

• Command and Control: In this final stage, attackers establish a method to control the compromised device remotely, often using custom protocols or hijacking legitimate services for ongoing command and control communication.

Best Practices for Using the MITRE ATT&CK Mobile Matrix 

Let’s look at some useful steps for applying the Mobile Matrix to your security strategy.

Identify Tactics and Techniques Applicable to Your Mobile Environment

Each mobile environment is unique in its characteristics and vulnerabilities. Thus, you must assess your environment from various perspectives including the type of devices used, the operating systems they run, the apps installed, and the nature of the data they handle.

To start, familiarize yourself with the matrix’s structure. It’s organized into eleven tactic categories, each containing a list of associated techniques.

For each tactic there are several techniques, which are methods used to achieve these objectives. For example, under the “Initial Access” tactic, you might find techniques like “Drive-by Compromise” or “Phishing.”

Next, evaluate your mobile environment. What are its most significant vulnerabilities? What types of threats have you experienced or do you anticipate?

As you answer these questions, you’ll start to identify tactics and techniques that are most likely to be used against you.

For instance, if your organization heavily uses mobile email, you might be particularly vulnerable to phishing attacks.

For Each Technique, Develop Specific Countermeasures

Once you’ve identified the tactics and techniques most applicable to your mobile environment, the next step is to develop specific countermeasures or security controls for each.

The MITRE ATT&CK Mobile Matrix not only provides information about potential threats, but also suggestions for mitigation and detection. These provide an excellent starting point for developing your defense strategies.

For example, if you’ve identified “Phishing” as a relevant technique, one mitigation strategy could be to implement a robust email security system that includes spam filters and phishing detection.

You could also provide training to your employees about how to recognize and report phishing attempts.

Continuously Monitor for Indicators of Compromise (IoC)

Continuous monitoring for threat indicators is crucial because cyber threats are continually evolving, and what works today may not work tomorrow.

Regular monitoring allows you to identify new threats quickly and adjust your defense strategies accordingly.

There are various tools and services available to assist with continuous monitoring. These include intrusion detection systems (IDS), security information and event management (SIEM) solutions, and endpoint detection and response (EDR) tools.

Such systems can provide real-time alerts, detailed reports, and insights into potential threats.

Conduct Simulation Exercises Based on Scenarios from the Matrix

Simulations can help your security team become familiar with the tactics and techniques of potential adversaries, and allow them to practice responding to such threats in a controlled environment.

Start by creating realistic scenarios based on the tactics and techniques you’ve identified as relevant.

For instance, if you’ve identified phishing as a significant threat, you could simulate a phishing attack on your organization. You could then assess your team’s response, identifying strengths and areas for improvement.

Make these exercises as realistic as possible. Use the same tools and techniques that an actual adversary would use.

This will give your team valuable experience and help them develop the skills they need to respond effectively to real-world threats.
