Supply Chain Attack in Short

  • A supply chain attack is a type of cyber attack that targets the weak points in an organization’s supply chain to gain access to sensitive information or disrupt operations.
  • This attack can be carried out at various supply chain stages, from the initial product development and design phase to the manufacturing and distribution phase, to the final installation and maintenance phase.
  • Supply chain attacks often involve the insertion of malicious code or hardware into legitimate products or services, which are then delivered to the target organization through the supply chain.
  • Common types of supply chain attacks include malware injection, counterfeiting, and tampering with software updates.
  • Supply chain attacks can have serious consequences for organizations, including the loss of sensitive data, financial losses, and damage to reputation.
  • To protect against supply chain attacks, organizations should implement robust cybersecurity measures throughout their supply chain, including conducting regular risk assessments, implementing secure coding practices, and verifying the integrity of all software and hardware components.

A Brief explanation of what a supply chain attack is

A cyber supply chain attack is a type of cyber attack in which the attacker targets a vulnerability in a company’s supply chain to gain access to the company’s systems or networks. This attack is often used to gain access to sensitive data or disrupt the company’s operations. It can be carried out by targeting a specific company or a company that is part of the supply chain of a larger organization.

The increasing prevalence of supply chain attacks in the digital age is due to several factors. First, the growth of global supply chains has made it easier for attackers to target multiple companies in a single attack. Second, using third-party vendors and contractors in the supply chain has created more potential points of entry for attackers. Finally, the increasing reliance on technology and the interconnectedness of systems has made it easier for attackers to spread malware and gain access to sensitive data.

Supply chain attacks are becoming increasingly common in the modern digital landscape. As companies rely more heavily on global supply chains and third-party vendors, the number of potential points of entry for attackers has increased. Additionally, the increasing use of technology and the interconnectedness of systems has made it easier for attackers to spread malware and gain access to sensitive data. As a result, supply chain attacks are a growing concern for many companies and organizations.

How a supply chain attack works

A supply chain attack typically targets a vulnerability in a company’s supply chain to gain access to the company’s systems or networks. This can be done in many ways, including:

  1. Malware injection: The attacker injects malware into a company’s systems through a supply chain partner, such as a third-party vendor or contractor. The malware can then be used to gain access to sensitive data or disrupt the company’s operations.
  2. Phishing: The attacker uses phishing techniques to trick employees at a supply chain partner into giving them access to the company’s systems or networks. This can be done through email, social media, or other means.
  3. Fake updates: The attacker creates fake software updates distributed through the supply chain. These updates give the attacker access to the company’s systems or networks when installed.

Once the attacker has gained access to the company’s systems or networks, they can steal sensitive data, disrupt operations, or carry out other malicious activities. The specific goals of the attack will depend on the attacker’s motivations and objectives.

What are the five biggest supply chain issues?

There are many potential supply chain issues that companies may face. Here are five of the biggest supply chain issues:

  1. Visibility and transparency: Many companies lack visibility into their supply chains, making it difficult to identify potential risks and manage the flow of goods and services.
  2. Globalization: The growth of global supply chains has introduced several challenges, including increased complexity, longer lead times, and greater risk exposure.
  3. Sustainability: As consumers and regulators become more focused on sustainability, companies face increasing pressure to reduce their environmental impacts and ensure that their supply chains are sustainable.
  4. Security: Supply chain security is a growing concern as attackers increasingly target supply chains to gain access to sensitive data or disrupt operations.
  5. Resilience: Supply chains are often vulnerable to disruptions, whether from natural disasters, political instability, or other events. Ensuring the resilience of supply chains is critical to maintaining the flow of goods and services.

Examples of recent supply chain attacks

There have been many examples of recent supply chain attacks. Here are a few examples:

  1. In 2017, the “Petya” ransomware attack targeted a Ukrainian accounting software company, which was then used to attack companies in the supply chain of a major multinational corporation.
  2. In 2018, the “Meltdown” and “Spectre” vulnerabilities were discovered in computer processors, which attackers could exploit to gain access to sensitive data. These vulnerabilities were present in many devices and systems, including those used by companies in their supply chains.
  3. In 2019, the “Kaspersky Supply Chain Attack” targeted the supply chain of the Russian cybersecurity firm Kaspersky Lab. The attackers used a fake software update to access the company’s systems and steal sensitive data.
  4. In 2020, the “SolarWinds” supply chain attack targeted the software supply chain of a major American technology company. The attackers used a fake software update to access the company’s systems and steal sensitive data.
  5. In 2022, SentinelLabs has discovered a new phishing campaign targeting users of the Python Package Index (PyPI), a popular repository for open-source Python libraries. The attackers, believed to be the same group behind the “JuiceLeder” malware, are using fake PyPI packages to distribute malware. The malware, called “PyPI Malicious Package,” establishes a hidden connection with the attacker’s command and control server, allowing the attacker to access the user’s device. This attack is notable because it represents a shift in tactics for the “JuiceLeder” group, who previously targeted users through fake app downloads. The use of supply chain attacks to distribute malware is a growing concern, highlighting the need for effective endpoint protection to defend against these threats.

Are there any examples of supply chain attacks on macOS devices?

Some would still claim that macOS is more secure than Windows, while our experience is that attackers are targeting Apple operating system more than ever before. However, no operating system is completely secure, and both macOS and Windows require regular updates and security patches to stay protected. There have been several examples of supply chain attacks targeting macOS devices. Here are a few examples:

  1. In 2018, the “MacDownloader” malware was discovered in the supply chain of an app developer. The malware was distributed through a fake update to the app, which gave the attackers access to the user’s macOS device.
  2. In 2019, the “Shlayer” malware was discovered in the supply chain of a software company. The malware was distributed through a fake update to the software, which gave the attackers access to the user’s macOS device.
  3. In 2020, the “XCSSET” malware was discovered in the supply chain of a popular Chinese app store. The malware was distributed through a number of apps on the app store, which gave the attackers access to the user’s macOS device.
  4. In 2022, SentinelLabs has discovered a new supply chain attack targeting macOS devices. The attack, which uses malware called “Pymafka,” is distributed through a fake update to a popular open-source Python library. Once installed, the malware establishes a hidden connection with the attacker’s command and control server, allowing the attacker to gain access to the user’s device. This attack is notable because it uses an obfuscated beacon to establish the hidden connection, which makes it difficult to detect. The use of obfuscated beacons in this type of attack signals a new trend in macOS attacks, and highlights the need for effective endpoint protection to defend against these threats.

These are just a few examples of supply chain attacks targeting macOS devices. As the use of macOS devices continues to grow, we will likely see more of these types of attacks in the future.

Are there any examples of supply chain attacks targeting Linux devices?

Yes, there have been several examples of supply chain attacks targeting Linux devices. Here are a few examples:

  1. In 2019, the “Drupalgeddon2” vulnerability was discovered in the Drupal content management system. The vulnerability was exploited in a supply chain attack, allowing attackers to access the user’s Linux device through a vulnerable website.
  2. In 2020, the “Zerologon” vulnerability was discovered in the Windows Server operating system. The vulnerability was exploited in a supply chain attack, allowing attackers to access the user’s Linux device through a vulnerable network.
  3. In 2021, the “Bashware” malware was discovered in the supply chain of a Linux distribution. The malware was distributed through a fake update to the distribution, which gave the attackers access to the user’s Linux device.

These are just a few examples of supply chain attacks targeting Linux devices. As the use of Linux continues to grow, we will likely see more of these types of attacks in the future.

The consequences of a supply chain attack

The consequences of a supply chain attack can be significant, both for the targeted company and any company in its supply chain. Some possible consequences of a supply chain attack include:

  1. Loss of sensitive data: A supply chain attack can result in the theft of sensitive data, such as customer information, financial data, or intellectual property. This can damage the company’s reputation and lead to financial losses.
  2. Disruption of operations: A supply chain attack can disrupt a company’s operations, leading to lost productivity and revenue. This can ripple effect throughout the supply chain, affecting other companies.
  3. Damage to reputation: A supply chain attack can damage a company’s reputation, making it difficult to attract customers and partners. This can have long-term consequences for the company’s business.
  4. Legal and regulatory consequences: A supply chain attack can also result in legal and regulatory consequences, such as fines or penalties for failing to protect sensitive data. This can further damage the company’s reputation and financial health.

Supply Chain Attack FAQs

A supply chain attack targets trusted third-party components—like software libraries, build tools, or service providers—to breach a final customer. Instead of attacking an organization directly, attackers insert malicious code or backdoors into vendor products or updates. When the victim installs or runs those compromised assets, the hidden malware executes, giving attackers access under the guise of legitimate software.

In 2020, the SolarWinds Orion platform updates were trojanized, impacting over 18,000 customers and U.S. agencies. In 2017, NotPetya spread via a malicious update to Ukrainian MeDoc software, crippling global networks.

Target’s 2013 breach began with stolen HVAC vendor credentials, allowing malware in its point-of-sale systems and exposing 40 million cards. Stuxnet was delivered via infected industrial controllers to subvert Iran’s uranium-enrichment centrifuges.

They exploit trusted relationships and widely distributed software, giving attackers a “one-to-many” path to high-value targets. Since compromised updates come from legitimate vendors, they bypass typical defenses and can remain undetected for months.

The ripple effect means a single breach can cascade through entire industries or critical infrastructure, amplifying impact far beyond a direct attack on one organization.

Attackers can strike during development (inserting backdoors into source code or compilers), in build and CI/CD pipelines (compromising build servers or signing keys), in distribution (tampering with installation packages or update servers), and even post-deployment (infecting patch processes or third-party integrations). Any stage where code or components move between parties is vulnerable.

They gain initial access to a vendor’s environment—often via stolen credentials or unpatched vulnerabilities—then implant malicious code into software components or update channels. When the vendor publishes an update, the altered package carries the payload to all downstream customers.

Attackers may also compromise development tools like compilers to stealthily infect every build.

Here are some common methods used in supply chain attacks:

  • Trojanized updates: injecting malware into software patches or installers.
  • Compiler attacks: corrupting build tools so all compiled binaries include hidden payloads.
  • Third-party library tampering: inserting malicious functions into open-source dependencies.
  • Credential theft: hijacking vendor admin or code-signing keys to authorize malicious releases.

Maintain an up-to-date Software Bill of Materials (SBOM) for every application. Enforce strict vendor security assessments and require code-signing with hardware-backed keys. Run automated checks on build artifacts, scan dependencies for known vulnerabilities, and isolate build infrastructure from general networks. Implement runtime monitoring to catch anomalous behavior even if malware slips through.

NIST SP 800-161 provides guidance on supplier security risk management. The Software Supply Chain Assurance (SCCA) framework and SLSA (Supply-chain Levels for Software Artifacts) set benchmarks for build integrity. Tools like SPDX for SBOM generation, in-toto for end-to-end build verification, and OWASP Dependency-Check automate detection of risky dependencies.

Supply chains weave together vendors, integrators, and customers. Sharing indicators of compromise, SBOM data, and threat intelligence helps all parties spot anomalies faster. Coordinated vulnerability disclosures and joint incident response reduce dwell time.

Without collaboration, gaps emerge when each organization assumes another will catch threats, leaving weak links wide open.

SentinelOne doesn’t directly state that it can prevent supply chain attacks. But its autonomous cybersecurity offers can detect malicious behaviors with AI and identify compromised endpoints. You can locate malicious files and processes, spot abnormal activity outside business hours, and limit the scope of damage by preventing infections across supply chains.

Overall, SentinelOne can help prevent supply chain attacks by providing continuous threat monitoring, advanced threat detection, and endpoint protection.
