Supply Chain attacks in Cyber Security: The types of Supply Chain Attacks hit quickly and violently. As an example, the CISO of a company recently experienced a $4.2 million ransomware event caused by a single vendor software update.
Due to this incident, all factories have been shut down globally and the Board is demanding answers immediately about how the attack happened. An incorrect update can result in total financial ruin for a company. Read more about how Spot Attacks can save your company millions of dollars and lead to a CISO Promotion.
Supply chain attacks are capable of infecting all of your suppliers/vendors. Companies install, and trust, updates for their software on a daily basis, frequently failing to verify the legitimacy (or lack thereof) of the update itself.
Use the information contained in this guide to identify every type of Supply Chain Attack, learn from real-life incidents, recognize shocking statistics, and identify ways to protect your organization. Learn these skills before the next Board meeting!

What is a software supply chain attack
The CISO’s dashboard displayed several red warning lights due to an update caused by a trusted vendor. A report by the team indicated that the latest patch contained a hidden backdoor that would allow access to the company’s entire network.
The primary target for malware that hides in vendor updates is elsewhere outside of the vendor’s site. Once an update is identified, other customers receive the same update automatically with no known detection methods.
The Software Supply Chain is poisoned through vendor updates containing hidden malware. All current vendor tools allow authentication using Digital Signatures, so updates pass security without alerts and activate remotely with no log indications.
The initial point of compromise is inside build pipelines where attackers access CI/CD servers to distribute code. When compiled, malware passes all standard checks but communicates back to the attacker.
Thousands of endpoints receive enterprise software updates where one infected library compromises the complete Corporate Directory. Recovery takes a minimum of 9 months and costs a considerable amount.
Types of supply chain attack in cyber security
Imagine a hacker at a security conference swapping demo USB drives. Your team grabs the infected one and compromises the entire network overnight.
Poisoning Software Updates:
Attackers steal vendor digital signing certificates to push fake updates. Customers auto-install trusting valid signatures. SolarWinds showed perfect software update poisoning execution.
Hardware Implants:
Factory insiders insert rogue chips during manufacturing. Devices work normally but leak data constantly to hackers. Only X-ray scans detect these hidden implants.
Third-party Library Injection:
Developers pull npm/PyPI libraries daily risking malicious injections. One bad library spreads to millions of applications silently. Code scanning tools catch most compromises.
Supply chain attack example
CISO receives emergency call at 2 AM. “All production servers have been encrypted.” Vendor patch triggered ransomware and it affected five countries at the same time.
- Attackers exploiting SolarWinds Orion had over 18,000 victims.
- Attackers who exploited Kaseya VSA demanded a ransom of $70 million.
- A bash script used by Codecov was compromised by attackers.
- An attempted backdoor was discovered in XZ Utils.
- Attackers spread malware via the 3CX Desktop App.
Attackers who exploited SolarWinds infiltrated the build server for many months before injecting a backdoor into one percent of all updates for the SolarWinds Orion product. The US Government and numerous Fortune 500 companies were infected. Attackers were able to extract terabytes of data from SolarWinds without detection.
Attackers who exploited Kaseya spread ransomware to their Managed Services Providers (MSPs). One vendor compromise impacted 1,500 customers or more. Attackers were able to demand $70 million in ransom from Kaseya, demonstrating the power of supply chain amplification. MSPs had total faith in Kaseya.
Attackers compromised the Codecov Bash uploader functionality that was part of the Continuous Integration/Continuous Deployment process by adding three lines of code that stole AWS keys from three million CI/CD pipelines. This simple edit to the existing script led to the largest credential theft in history.
Recent supply chain attacks
There will be a board meeting tomorrow, but we’ll be discussing a vendor security alert that just came in today. These are the most recent attacks that have occurred in the last twelve months, please check with your vendors immediately.
- MOVEit Transfer Zero-Day (2023)
- Ivanti VPN Backdoor (2024)
- Polyfill.io Crypto-Miner Injection
- Laravel Ignition Exploit
- Progress Software Data Breach
MOVEit File Transfer was compromised by Clop Ransomware. More than 2,000 companies lost their customers’ data as a result of using Trusted File Sharing. This is a perfect example of how a single vulnerability can be amplified across the globe by Supply Chain attacks.
The Ivanti VPN update included Chinese Backdoors and Enterprise customers that had their devices automatically updated without checking to confirm the validity of the vendor’s signature are vulnerable because all authentication of updates can be easily bypassed through update verification failure.
Bad actors acquired Polyfill.io and infected their JavaScript CDN with miners that were then injected into 130,000 different sites. The developers of these sites did not check the content of the CDN prior to deploying it into production.
Supply chain cyber attacks statistics
SIEM alerts spike 300% from vendor IP ranges overnight. These numbers prove attacks exploding – update board briefing immediately.
- 60% enterprises hit in 2024
- Average cost $12.5M per incident
- 45% involve third-party vendors
- 78% open source vulnerable
- 84 days average detection time
2024 surveys show 60% enterprises faced supply chain compromise. $12.5M average cost includes downtime, fines, and remediation. Vendor involvement in 45% cases proves trust betrayal scale.
Open source dominates risk landscape. npm registry hosts 2M+ packages with minimal review. Single compromised package infects thousands of downstream applications instantly.
Ransomware via supply chain doubled since 2022. Attackers target vendors serving multiple customers for maximum payout. MSPs amplify damage reaching thousands through single breach.
Supply chain cyber attack approaches
CISO presentation: “Through a CRM vendor’s online store” these are the specific methods by which these criminal organisations compromise systems each day.
- Compromised updates
- Stolen signing credentials
- Internal access from vendors.
- Dependency confusion attacks.
- Typosquatting attack packages.
Compromised update servers are the most straightforward way in for attackers. The attackers gain administrator access and distribute malicious updates directly to the companies’ customers. All security tools see the digital signatures as still being valid.
Stolen certificates completely eliminate the need for any type of verification. Attackers usually steal private keys from GitHub repos and/or the developer’s laptop, and then are able to sign their own malware (which appears legit) with those certificates.
Dependency confusion attacks are based upon deceiving build automation systems. Attackers create public packages using the same names as internal libraries, thus, when a build is done, the pip/nmp package installer will install the public version created by the attacker.
Supply chain attack prevention
Vendor calls urgently: “We have resolved the problem.” Do not trust them yet. You must independently verify that they are in compliance with the following five procedures.
- Verify all code signature locations.
- Implement the Software Bill of Materials.
- Perform a vendor security audit.
- Enable Runtime Integrity Monitoring.
- Automated scanning for Dependencies.
90% of all attacks can be prevented if you verify the Code Signing. Unsigned binaries should be rejected automatically at the network edge. Vendors should have rotating certificates on a quarterly basis, and CRLs should be monitored continuously.
The Software Bill of Materials lists each and every component in your system. You can generate Software Bills of Materials from your container images using Syft or Trivy and should scan daily against Vulnerability Databases to block High-Risk versions.
You should conduct vendor audits at least annually. Require vendors to provide either a SOC2 Type II Report and/or an Independent Penetration Testing report. Contract language should require that vendors notify you within 24 hours of a data breach and provide proof that they have fully remediated the issue.
Hardware vs software supply chain attacks
A shipment containing new server pallets arrived in a warehouse, but upon inspecting it via X-ray scanner it was discovered that the potential presence of unauthorized chips (in the form of fingernail-size boxes filled with various types of chips) could create an opportunity for attacks that could not be detected by any type of software-based protective measures.
- Hardware-based attacks often incorporate the use of physical implants (the unauthorized chips) as the attack vector, while software-based attacks use injected and/or trojanized (malicious) code as the attack vector.
- Hardware attacks take place during the manufacture of devices, while software attacks target the process of building devices.
- Each type of attack is detected using a different method (e.g., hardware requires physical inspection and use of X-ray equipment, while software requires use of behavioral-based analytics and constant memory forensics).
Vendor risk management strategies
Before signing these vendor agreements, you need to ensure that you have received this “checklist” to establish the vendor’s risk to your business, in order to avoid compromising your company completely.
- Third-Party Risk Scoring System: Give vendors a Security Rating (score) from 1-10 based on the Risk Assessment (Audit) and Breach History at Day 1.Any vendor with a Security Rating (score) below 7 should be eliminated due to cost savings.
- Contract Clauses Establish Minimum Security Requirements: Vendors should provide timelines for Vulnerability Disclosure, as well as the Right to Audit:Vendors must also notify you of any breaches within 24 hours and provide full details of the incident.
- Continuous Monitoring for Vendor Health: A vendor should send out automated alerts if it appears in breach databases; Dark Web Monitoring should also assist in capturing compromised vendor credentials.
Open source supply chain security
Every 5 minutes, the DevOps pipeline pulls from the npm package repository. A single malicious dependency could cripple production in 50 different countries instantaneously.
- Automated dependency scanning, verification of lockfile hashes, a check of build provenance, verifying reproducibility of builds, and using trusted mirrors for packages is an approach to mitigating risk in a developer’s workflow when depending on third-party packages.
Dependency scanners, such as Snyk, automatically block high-risk packages, and all changes should be reviewed weekly to reject unapproved updates. Maintain an allowlist of only verified safe packages.
Prevent floating requirements by always locking every package version with a lockfile. Always verify that the SHA256 hash matches the expected value before installation is complete.
Follow the SLSA framework to produce evidence of build integrity. Use immutable cryptographic provenance to track everything from source to binary and confirm the matched state of both.
Attack detection frameworks
The legitimate IP addresses of vendors send alerts through SIEM Consoles for these frameworks informing the dwell phase of supply chain attacks.
- Behavioral Analytics Platforms
- Monitoring File Changed
- Threat Hunting – Proactive
- Endpoint Detection Integrated
- Anomalies Processed With Rules
Behavioral Analytics Identify Children Processes Not Associated With Legitimate Software Alerts Of Unusual Behavior. If A Legitimate Application Creates A PowerShell Or CMD.EXE Process, This Initiates An Immediate Investigation. The Machine Learning Models Establish Baselines Of Normalized Activity And Block Outlier Activity Automatically.
Monitoring File Changes Enforces Integrity Of Critical System Files. If An Unexpected Change Occurs To A Legitimate Binary, It Is Contained. Verifying File Change Against Vendor Hashes Before Allowing The File To Execute.
Endpoint Detection Response Hunts For Persistence Mechanisms, Such As Scheduled Tasks, Registry Run Keys And WMI Subscriptions Associated With Supply Chain Implants. Automated Playbooks Are Created For Immediate Response To Thwart Confirmed Threats.
Future attack predictions
As the 2026 CISO report comes out, there is a major shift in how we look at security because of Artificial Intelligence.
- AI has the capability to create malware that is completely undetectable.
- No longer can an organization rely solely on traditional methods to identify malware since every new attack will become increasingly automated by Machine Learning creating “perfect” matches for malware deployed to the target binary files.
- Attacks are evolving at a significant pace as attackers deploy AI models that continuously learn how to evade detection.
- Quantum Computing will be able to break the RSA/ECDSA signatures by 2030, so organizations need to immediately begin transitioning to Post-Quantum Cryptography.
- Securely storing signing keys with Hardware Security Modules will prevent them from being harvested now to be decrypted later with Quantum Computers.
- The number of IoT devices in existence is projected to exceed 75 billion by 2026, and every one of these devices will have backdoors built into them.
- Cheap firmware from China is the dominate manufacturer.
- As a measure of good security, every IoT deployment will need to have a physical verification performed no matter how much it costs.
