MOVEit is a widely adopted managed file transfer (MFT) solution developed by Progress Software. It enables organizations to securely transfer sensitive data between internal systems, business partners, and external vendors. MOVEit’s robust encryption, automation, and compliance features have made it a cornerstone in the digital supply chains of enterprises across finance, healthcare, government, and other sectors.

Given its central role in facilitating data exchange, MOVEit is deeply integrated into many organizations’ operational workflows. This integration, while beneficial for efficiency, also introduces supply chain vulnerabilities—a single compromise can cascade across multiple entities, amplifying the impact of a breach. For more on the risks associated with third-party software, see CISA’s Supply Chain Risk Management resources. Understanding how credential stuffing and other indirect attacks can exploit such vulnerabilities is also crucial for organizations managing digital supply chains.

The MOVEit supply-chain breach 2024 was first detected in late March, when anomalous activity was observed on several customer instances. Security teams noticed unauthorized data exfiltration attempts, prompting immediate investigation. Early indicators suggested exploitation of a previously unknown vulnerability within the MOVEit Transfer application.

By early April, Progress Software and several cybersecurity firms, including CrowdStrike and Mandiant, publicly disclosed the breach. Advisories were issued to all MOVEit customers, urging them to apply emergency patches and review system logs for signs of compromise. The Cybersecurity and Infrastructure Security Agency (CISA) also released an alert, emphasizing the widespread nature of the attack.

As the scope of the breach became clear, incident response teams identified that the attackers had leveraged the vulnerability to access sensitive files across hundreds of organizations. The attack escalated rapidly, with threat actors deploying additional malware and establishing persistence mechanisms. Over the following weeks, affected organizations coordinated with law enforcement and cybersecurity experts to contain the breach and assess the full extent of the damage.

The primary attack vector in the MOVEit supply-chain breach 2024 was a zero-day vulnerability in the MOVEit Transfer software. The flaw allowed remote attackers to execute arbitrary code and bypass authentication controls, granting them unauthorized access to sensitive data repositories. According to Rapid7 analysis, the exploit chain involved:

• Injection of malicious SQL queries to escalate privileges
• Deployment of web shells for persistent access
• Exfiltration of encrypted data archives

The attackers demonstrated a high level of sophistication, employing evasion techniques to bypass endpoint detection and response (EDR) systems and leveraging encrypted communication channels to avoid network monitoring tools.

While the breach was primarily technical, there were also elements of social engineering. Attackers sent phishing emails to IT administrators, masquerading as legitimate MOVEit support notifications. These emails contained malicious links designed to harvest credentials or deploy secondary payloads. The use of social engineering increased the attack’s success rate and enabled lateral movement within targeted organizations. For more on social engineering tactics, refer to SANS Institute’s Social Engineering Whitepaper.

The breach exploited inherent weaknesses in the software supply chain. Many organizations relied on default configurations and delayed patching, leaving them exposed. Additionally, the interconnected nature of supply chains meant that a compromise in one entity could be leveraged to access partners and downstream customers. This “island hopping” technique has been observed in other high-profile incidents, such as the SolarWinds breach (CISA Advisory on SolarWinds). Exploring the evolving landscape of supply chain attacks can provide additional context on these risks.

The MOVEit supply-chain breach 2024 affected a broad spectrum of organizations, including:

• Financial institutions
• Healthcare providers
• Government agencies
• Retailers and logistics companies

According to BleepingComputer, over 1,200 organizations worldwide reported incidents related to the MOVEit breach, with the majority based in North America and Europe.

The data compromised in the breach included:

• Personally identifiable information (PII) such as names, addresses, and Social Security numbers
• Financial records and payment information
• Confidential business documents
• Healthcare records

Estimates from Unit 42 suggest that over 25 million individual records were exposed, making this one of the largest data breaches of 2024.

Beyond data loss, the breach caused significant operational disruption. Organizations were forced to suspend file transfers, initiate emergency incident response protocols, and notify affected customers and regulators. The financial impact included costs related to forensic investigations, legal fees, regulatory fines, and reputational damage. For a detailed breakdown of breach costs, see IBM’s Cost of a Data Breach Report.

Upon discovery, affected organizations and Progress Software took several immediate steps:

• Isolated compromised MOVEit servers from the network
• Applied emergency patches and hotfixes provided by the vendor
• Conducted forensic analysis to identify indicators of compromise (IOCs)
• Reset credentials and revoked potentially compromised access tokens

Guidance from FIRST (Forum of Incident Response and Security Teams) was instrumental in coordinating a rapid response across multiple sectors.

Long-term remediation efforts focused on:

• Comprehensive vulnerability assessments of all third-party software
• Implementation of enhanced monitoring and logging
• Review and tightening of access controls
• Engagement with external cybersecurity experts for ongoing risk assessments

Many organizations also accelerated their adoption of Zero Trust architectures to minimize the risk of lateral movement in future incidents. For more on Zero Trust, see NIST Special Publication 800-207.

Transparent and timely communication was critical. Organizations notified affected individuals, business partners, and regulators in accordance with data breach notification laws. Public relations teams worked to manage reputational impact, while legal teams ensured compliance with GDPR, HIPAA, and other relevant regulations. For best practices in breach notification, refer to ISO/IEC 27035-3:2018.

The MOVEit supply-chain breach 2024 reaffirmed the necessity of robust supply chain security. Organizations must recognize that their security posture is only as strong as their weakest link. Proactive risk management, continuous monitoring, and collaboration with vendors are essential to mitigate supply chain threats. For a comprehensive framework, see NIST’s Key Practices in Supply Chain Risk Management. Conducting professional password audits and regular testing can also strengthen organizational resilience against similar threats.

Effective vendor risk management involves:

• Conducting thorough due diligence before onboarding new vendors
• Regularly reviewing vendor security practices and certifications
• Establishing clear contractual obligations for incident reporting and remediation
• Maintaining an up-to-date inventory of all third-party software and services

For guidance, refer to ISACA’s Vendor Risk Management in the Supply Chain.

Timely patch management and responsible vulnerability disclosure are critical. The MOVEit breach highlighted how delays in applying patches can have catastrophic consequences. Organizations should:

• Implement automated patch management solutions
• Monitor for vendor advisories and threat intelligence feeds
• Participate in coordinated vulnerability disclosure programs

For more on vulnerability management, see OWASP Vulnerability Management Guide.

Human error remains a significant risk factor. Regular security awareness training can help employees recognize phishing attempts and social engineering tactics. Training should be tailored to different roles and include simulated exercises. For effective training strategies, consult CIS Security Awareness and Training Programs. Organizations may also benefit from reviewing current password cracking myths and facts to enhance employee understanding of real-world attack methods.

To prevent future supply chain breaches like the MOVEit incident, organizations should:

• Integrate third-party risk assessments into procurement and onboarding processes
• Leverage standardized assessment frameworks such as CIS Controls
• Require vendors to provide evidence of regular security testing and compliance
• Continuously monitor vendor performance and risk posture

For organizations looking to strengthen their defenses, reviewing best practices for third-party risk management is highly recommended.

Adopting a Zero Trust security model can significantly reduce the risk of supply chain attacks. Key principles include:

• Never trust, always verify—authenticate every user and device
• Enforce least privilege access controls
• Segment networks to limit lateral movement
• Continuously monitor and analyze user behavior

For implementation guidance, see CISA Zero Trust Maturity Model.

Routine security audits and penetration testing are essential for identifying and mitigating vulnerabilities before they can be exploited. Best practices include:

• Conducting annual or bi-annual penetration tests by certified professionals
• Performing regular internal and external vulnerability scans
• Reviewing audit logs for suspicious activity
• Remediating findings promptly and tracking progress

For more on penetration testing methodologies, refer to OffSec’s Metasploit Unleashed.

The MOVEit supply-chain breach 2024 serves as a stark reminder of the evolving threat landscape and the critical importance of supply chain security. By understanding the attack vectors, impact, and response strategies, organizations can better prepare for future incidents.
