MOVEit Transfer Attack

MOVEit Transfer Attack TTP for Malware Analyst

Overview

MOVEit Transfer is a secure file transfer solution organizations use to exchange sensitive data. While the product is designed to be secure, attackers may still target the users, infrastructure, or underlying systems to compromise the transferred data. The TTP (Tactics, Techniques, and Procedures) for a MOVEit Transfer attack would outline how an attacker might exploit various aspects of the system to deploy malware or exfiltrate sensitive data.

Tactics

  1. Initial Access: The attacker gains access to the target system, either through phishing emails, exploiting vulnerabilities in the underlying infrastructure, or compromising user credentials.
  2. Execution: The attacker executes malicious code on the target system or within the MOVEit Transfer environment, potentially using compromised credentials or exploiting vulnerabilities.
  3. Persistence: The attacker establishes persistence on the target system, ensuring their malware remains active even after a reboot or system update.
  4. Privilege Escalation: The attacker exploits vulnerabilities or misconfigurations to elevate their privileges within the MOVEit Transfer environment or the underlying system.
  5. Defense Evasion: The attacker employs techniques to avoid detection by the security software, such as obfuscating their code, turning off security features, or blending in with legitimate traffic.
  6. Credential Access: The attacker steals user credentials, either through social engineering, keylogging, or by exploiting vulnerabilities in the MOVEit Transfer environment or underlying systems.
  7. Lateral Movement: The attacker uses the compromised credentials to move laterally within the target network, potentially infecting additional systems or accessing more sensitive data.
  8. Collection: The attacker collects sensitive data from the target system, such as intellectual property, financial data, or personally identifiable information (PII).
  9. Exfiltration: To avoid detection, the attacker exfiltrates the collected data, potentially using the MOVEit Transfer system or other encrypted channels.
  10. Command and Control (C2): The attacker establishes a communication channel with the compromised system, allowing them to control the malware and issue commands remotely.

Techniques

  • Spear Phishing: The attacker sends a targeted phishing email to the victim, containing a malicious attachment or link that exploits vulnerabilities in the underlying infrastructure or tricks the user into revealing their MOVEit Transfer credentials.
  • Watering Hole Attack: The attacker compromises a website frequently visited by the target organization’s employees and uses it to deliver malware or steal credentials.
  • Exploiting Vulnerabilities: The attacker identifies and exploits vulnerabilities in the underlying infrastructure (e.g., web server, operating system) or the MOVEit Transfer application itself.
  • Social Engineering: The attacker uses social engineering techniques to obtain user credentials, such as posing as a legitimate support representative or a fellow employee.
  • Man-in-the-Middle (MITM) Attack: The attacker intercepts and manipulates network traffic between the user and the MOVEit Transfer system, potentially stealing credentials or injecting malicious code.
  • Fileless Malware: The attacker leverages fileless malware that resides in memory, making it more difficult for security software to detect and remove the infection.

Procedures

  1. Identify the target organization and its MOVEit Transfer environment, including any known vulnerabilities or potential attack vectors.
  2. Develop or obtain the necessary exploits, payloads, or malware to compromise the target system or MOVEit Transfer environment.
  3. Choose an appropriate delivery method (e.g., phishing email, watering hole attack) to gain initial access to the target system or environment.
  4. Execute the exploit and deploy the malware, taking advantage of vulnerabilities, misconfigurations, or compromised credentials.
  5. Establish persistence, escalate privileges, and evade detection using the abovementioned techniques.
  6. Steal credentials, move laterally within the network, and collect sensitive data.
  7. Exfiltrate the collected data using the MOVEit Transfer system or other encrypted channels, and establish a C2 channel for ongoing control and communication.

As a malware analyst, understanding the TTPs associated with MOVEit Transfer attacks is crucial for defending against such attacks and developing effective countermeasures to protect sensitive data.
