What are Supply Chain Attacks?

A supply chain attack is a cyberattack strategy that targets trusted third-party vendors or suppliers within an organization's supply chain network, exploiting vulnerabilities in their systems or software to gain unauthorized access to the target organization's network or data. These attacks compromise the integrity of the entire supply chain, allowing attackers to propagate malicious code or malware to unsuspecting downstream users.

Supply Chain Attacks Explained

A supply chain attack is a sophisticated cyberattack strategy that strategically targets trusted third-party vendors or suppliers within an organization's intricate supply chain network. These malicious attacks take advantage of the established trust between organizations and their suppliers, exploiting vulnerabilities within the supplier's systems or software to gain illicit access to the target organization's valuable network or sensitive data. This insidious tactic allows cybercriminals to infiltrate the organization's defenses and wreak havoc on their digital infrastructure without detection until it's too late.


How Supply Chain Attacks Work

Supply chain attacks unfold through several interconnected steps, each designed to exploit vulnerabilities within the supply chain ecosystem:

  • Initial Compromise: Attackers identify and exploit vulnerabilities within the systems or software of a trusted supplier, gaining unauthorized access to their infrastructure.

  • Malicious Payload Injection: Once access is gained, attackers inject malicious code or malware into legitimate software updates or applications provided by the compromised supplier.

  • Distribution of Compromised Software: The compromised software updates, now containing malicious payloads, are distributed to unsuspecting downstream users or organizations through legitimate channels.

  • Propagation and Activation: Upon installation or execution of the compromised software updates, the malicious payloads are activated, granting attackers unauthorized access to the target organization's network or sensitive data.

  • Persistence and Concealment: Attackers establish persistence within the target organization's network, concealing their presence and maintaining access for future exploitation or data exfiltration.


Examples of Supply Chain Attacks

Supply chain attacks pose a major cyber threat by exploiting trusted suppliers' vulnerabilities to breach networks and compromise data. See the real-world examples below:

  • SolarWinds Attack: Attackers compromised the software build process of SolarWinds, injecting malicious code into legitimate software updates distributed to thousands of organizations, including government agencies and major corporations.

  • ASUS Live Utility Attack: Malicious actors compromised the update mechanism of ASUS Live Utility, distributing malware to users through pre-installed software updates on ASUS systems.

  • Open Source JavaScript Tool Attack: Attackers targeted the Browserify tool, injecting malicious code into open-source JavaScript libraries used by developers, aiming to compromise Linux and macOS operating systems.


What Role Does Email Play in Supply Chain Attacks?

Email serves as a primary vector for initiating supply chain attacks. Attackers commonly utilize phishing emails to target employees within an organization, posing as trusted suppliers or vendors to deceive recipients into opening malicious attachments or clicking on malicious links. By compromising email accounts or impersonating legitimate suppliers, attackers can initiate the chain of events leading to a successful supply chain attack.


How to Identify and Protect Against Supply Chain Attacks

Identifying and protecting against supply chain attacks requires a multi-faceted approach:

  • Advanced Security Controls: Implement robust cybersecurity measures, including email security solutions, endpoint protection, and network monitoring tools.
  • Risk Assessment: Conduct thorough vendor risk assessments and due diligence to evaluate the security posture of third-party suppliers.
  • Monitoring: Monitor for suspicious activity within the supply chain, such as unauthorized access attempts or unusual network traffic patterns.
  • Awareness Training: Educate employees about the risks of supply chain attacks and provide training on recognizing phishing attempts and other social engineering tactics.
  • Threat Intelligence: Stay informed about emerging threats and vulnerabilities within the supply chain landscape through threat intelligence feeds and cybersecurity resources.
