Supply Chain is a very crucial aspect for most businesses out there. An effective and secure supply chain is essential for making money for any company. This also makes it a primary target for hackers.
With supply chain attacks surging in numbers, we need to understand what they are. These sophisticated cyberattacks exploit vulnerabilities within the supply chain, targeting third-party vendors and service providers to compromise the security of their clients.
Understanding the mechanics of supply chain attacks, their potential impact, and strategies for prevention can help protect your organization’s infrastructure. In this blog, we will explore what supply chain attacks are, how they work, and the measures you can take to protect your business from these increasingly prevalent threats. Let’s get started.
What Is a Supply Chain Attack?
A supply chain attack is a sophisticated type of cyberattack that targets the weaker links in an organization’s supply chain, exploiting trusted third-party vendors who provide essential services or software. This form of attack uses the dependencies and interconnected nature of modern business operations to infiltrate a target’s system or network indirectly.
Supply chain attack statistics
Supply chain attacks have become increasingly relevant and concerning, particularly as they can affect any industry reliant on third-party vendors, such as finance, government, and e-commerce. The interconnected nature of modern supply chains means that a single compromised link can have widespread repercussions, making these attacks particularly dangerous.
To give you one shocking statistic, supply chain cyber attacks in the United States affected 2,769 entities in 2023. This marked the highest reported number since 2017, representing a year-over-year increase of approximately 58 percent, the largest surge recorded in recent years.
The Impact of Supply Chain Attacks
The impact of a supply chain attack can devastate corporate revenue and sever vendor relationships. More specifically, they could result in:
1. Data Breaches and Disclosure
Malicious code can eavesdrop on data and send it to an attacker-controlled server. Attackers can breach data passing through an infected system, including high-privileged account credentials for future compromises.
2. Malware Installation
Malicious code running within an application could download malware and install it on the corporate network. This could include ransomware, rootkits, keyloggers, viruses, and other malware types.
3. Monetary loss
Targeted organizations could lose millions if an employee is tricked into sending money to a fraudulent bank account or paying fake invoices.
4. Operational disruptions
Successfully executed supply chain attacks can severely disrupt an organization’s operations, leading to costly downtime, delays, and crippled productivity.
5. Reputational damage
When supply chain attacks affect the quality and reliability of an organization’s products or services, the outcome can severely damage its reputation, resulting in lost customer or vendor trust and loyalty.
How does a Supply Chain Attack Work?
Supply chain attacks work through a two-step process involving both “upstream” and “downstream” attacks. Initially, attackers gain access to a third-party system, application, or tool they plan to exploit. This upstream attack can be achieved in various ways, such as using stolen credentials, targeting vendors with temporary access to an organization’s system, or exploiting an unknown software vulnerability.
Once access to this third-party dependency is secured, the downstream attack — which targets the ultimate victims, often via their browsers or devices — can be carried out. For instance, an upstream attack might involve adding malicious code to a cybersecurity vendor’s software. The downstream attack then occurs when this malware is executed on end-user devices during a routine software update.
Most Common Types of Supply Chain Attack
1. Software Supply Chain Attacks
These involve injecting malicious code into a trusted application. When users download or update the compromised application, they inadvertently install malware, giving attackers access to their systems. The infamous SolarWinds attack in 2020 exemplifies this method, where malicious code was inserted into a software update, affecting thousands of customers.
2. Hardware Supply Chain Attacks
These compromise physical components within the supply chain. By tampering with hardware before it reaches its final destination, attackers can create vulnerabilities that allow for future exploits once the hardware is in use.
Example of Supply Chain Attack
Historically, supply chain attacks have exploited trusted relationships within a supply network. Here are a few examples
- A notable example is the 2013 attack on Target, where attackers gained access through an HVAC contractor, ultimately infiltrating Target’s systems. This highlights the strategy of attacking a smaller, less secure supplier to breach a larger, more secure target.
- The SolarWinds attack, a notorious supply chain breach, infiltrated the software’s build cycle, infecting approximately 18,000 downstream customers, including major corporations and government agencies. Despite strong cybersecurity measures, these entities fell victim to the injected malicious code, highlighting the vulnerability of even the most secure systems.
- In a similar sophisticated attack, the ASUS Live Utility, a pre-installed software on ASUS systems, was compromised, impacting over 57,000 users who unwittingly downloaded the compromised utility. This targeted attack, focused on users with specific MAC addresses, underscores the pervasive threat posed by supply chain vulnerabilities.
How do you Prevent and Detect a Supply Chain Attack?
Preventing and detecting supply chain attacks requires a multi-faceted approach, incorporating both proactive measures and reactive strategies. Here are some recommendations on how organizations can enhance their supply chain security:
1. Employ Behavioral-Based Attack Detection
Organizations should utilize solutions that incorporate behavioral-based analysis, such as indicators of attack (IOAs) and machine learning (ML). These technologies can detect patterns indicative of malicious activity, even in the absence of known signatures or patterns.
2. Use Threat Intelligence
Stay ahead of emerging threats by using threat intelligence services. These services provide insights into new supply chain attack techniques and help organizations understand the evolving threat landscape. Automated threat analysis tools, like the ones provided by CloudDefense.AI, can deliver contextual information to enable predictive security measures.
3. Enhance Readiness with Proactive Services
Engage in proactive services, such as supply chain analysis and tabletop exercises, to assess current exposure and readiness for supply chain attacks. These exercises simulate attack scenarios and provide organizations with actionable insights to enhance their protection and response capabilities.
4. Implement Systematic Verification Processes
Establish systematic verification processes to assess all potential pathways into the system. Conduct comprehensive inventories of assets and data pathways within the supply chain to identify security gaps and vulnerabilities.
5. Develop Threat Models
Create threat models specific to the organization’s environment, assigning assets to adversary categories and assessing their risk levels. Continuously update threat scores and prioritize assets based on their susceptibility to attacks.
6. Test New Updates
Thoroughly test all software updates to detect potential supply chain attacks. Automated tools should be employed to identify malware file activity, registry keys, and other indicators of compromise.
7. Evaluate Third-Party Risks
Assess the security posture of third-party vendors through self-assessments and due diligence processes. Limit the number of individuals authorized to install third-party software to reduce the attack surface.
8. Implement Access Controls
Review and limit access to sensitive data, granting permissions only to individuals who require it for their roles. Terminate access to organizational data promptly after ending contracts with vendors.
9. Invest in Cybersecurity Tools
Invest in tools provided by cybersecurity firms to enhance threat forensics and malware protection against advanced cyber threats. These tools can bolster the organization’s defense mechanisms and aid in threat detection and mitigation.
10. Use Government Initiatives and Frameworks
Utilize resources provided by government initiatives, such as the Comprehensive National Cybersecurity Initiative and the Mitre ATT&CK framework, to strengthen supply chain risk management practices and cybersecurity strategies.
