Supply chain attacks are a serious cybersecurity threat. They use trusted third-party vendors to attack systems. By exploiting software flaws in the supply chain, these attacks cause big breaches. In 2013, a breach through an HVAC contractor hit Target’s systems hard. The 2024 CrowdStrike Global Threat Report shows these attacks are increasing. It points out the risks from third parties and the change in how hackers attack.
A lot of security experts, 74% to be exact, have seen more of these threats recently. But 59% of companies don’t have a plan to deal with them. This makes it easier for attackers to succeed. We must know the risks of supply chain attacks. Then we can defend against them better.
Understanding Supply Chain Attacks
Supply chain attacks are a growing worry in the world of cybersecurity. They happen when attackers target the connections between companies and their suppliers or partners. These attacks don’t just hurt the main target but can also affect everyone linked to it.
Definition and Overview
To really understand supply chain attacks, you need to know what a cyberattack means. It’s when hackers find a way into a company’s system through the people and businesses it works with. This is often done through weak spots in third-party APIs, as companies use more external software now.
Historical Context and Evolution
Looking at past cyberattacks shows how supply chain threats have changed. At first, attacks targeted physical products. Now, they mostly go after software because of how much we depend on digital tools. For example, in 2013, Target was hit hard when hackers got in using credentials from an HVAC vendor, exposing 40 million card numbers.
The attacks have gotten smarter and wider-reaching. Take the 2020 SolarWinds attack as an example. It showed that malicious code could get into lots of systems, hitting 18,000 organizations, including parts of the U.S. government. This was a big alert about the dangers of trusting outside software and partners too much.
Examples of Major Supply Chain Attacks
Here are some major attacks that show how serious this issue is:
- SolarWinds Attack: This one hit around 18,000 customers, including important U.S. government networks.
- Target Breach: A major event in 2013, this attack got millions of payment card details through an HVAC vendor’s weak security.
- NotPetya Malware: Starting in Ukraine in 2017, this malware spread worldwide, affecting systems everywhere.
- ASUS Attack: Malware was put on devices right in the factory, hitting about 500,000 systems.
- Dependency Confusion: In 2021, hackers put bad code into popular software packages, exploiting open-source vulnerabilities.
- Mimecast Attack: This one targeted the company’s software tools, using stolen certificates to bring in malware.
Understanding these major incidents shows the different ways hackers attack through third-parties and weaknesses in systems. By knowing about past threats and how they’ve evolved, companies can get better at protecting themselves.
What Is a Supply Chain Attack
Supply chain attacks target systems via weak spots in third-party parts. They’re hard to spot and can cause big harm.
Types of Supply Chain Attacks
Knowing the different supply chain attacks can help lessen their threat. Be aware of attacks such as:
- Upstream server attacks: These go after the servers above, like the SolarWinds hack. Here, attackers hit the software before it gets to users.
- Midstream attacks: These focus on the middle data path. They aim to hit CI/CD setups or dev tools, inserting bad code in the software creation stage.
- Stolen SSL certificate: With a stolen SSL or code-signing cert, as seen in Stuxnet, attackers make harmful software seem safe.
- Dependency confusion attacks: This tricks with open-source software by putting bad code in cloned or alike-named packages on places like GitHub.
Common Attack Vectors
There are common points attackers hit within supply chains to spread malware or breach systems. These include:
- Exploiting Software Dependencies: Attackers slip in vulnerabilities by adding malicious code to dependencies devs use. It’s key to check all third-party software carefully.
- Cloning GitHub Repositories: This method makes a fake repository with malware. It’s to fool devs into using bad code in their work.
Knowing how upstream server attacks, midstream attacks, and others like stolen SSL certificate or dependency confusion attacks work is vital. Being proactive and aware helps fight these hidden dangers and protect your systems.
The Rising Threat and Statistics
The cybersecurity world is always changing. Now, supply chain attacks are happening more often, showing a big change in global threats. We are seeing more attacks and they are getting harder to fight.
Increasing Frequency of Attacks
Supply chain attacks are now a big worry in cybersecurity. For example, in 2021, the attacks grew three times compared to the year before. The Codecov incident went unnoticed for months, showing how sneaky these threats can be. The CCleaner attack affected millions of computers, proving the serious harm they can do. Hackers often use fake software updates to break into secure software.
Notable Statistics
Here are some important stats about supply chain attacks:
- In the Codecov breach, the attack went unnoticed from January 31 until April 1, 2021.
- The Biden Administration highlighted the criticality of addressing software supply chain attacks in May 2021
- 90% of companies and 97% of commercial codebases leverage open source components, expanding the potential attack surface.
- The average increase in software supply chain security attacks is a staggering 742% yearly.
- Python, as a rapidly growing language, with frameworks like Django and libraries such as PyTorch, exemplifies the immense dependencies susceptible to threats.
- Containers based on pure Debian exhibit widely known vulnerabilities that require constant vigilance and threat intelligence to manage.
These stats show how much we need better cybersecurity. Keeping an eye on our systems, using zero-trust models, protecting our devices, and making sure our code is safe are key. We must work together to fight the rise in attacks and smarter malware.
Why Supply Chain Attacks Are So Dangerous
Supply chain attacks are a big risk because they exploit trust and use complex networks. Organizations and their suppliers are closely linked. This lets cybercriminals sneak into these trusted relationships and manipulate them.
Exploiting Trust
Cybersecurity trusts in supplier networks make these attacks very alarming. The SolarWinds Orion attack is a prime example. Hackers tricked people with fake software updates to spread harmful code, causing a lot of damage. This breach could cost cyber insurance companies up to $90 million, showing its serious financial impact. Trust exploitation leads to breaches that affect many groups across different sectors.
Challenges in Detection and Prevention
Detecting and stopping supply chain attacks is hard due to their complex nature and how networks are connected. These networks depend on technology and partnerships, which might have weak spots. A report by Argon stated a 300% rise in software supply chain attacks in 2021. This highlights the growing danger.
Sonatype’s report from 2020 found that 90% of all applications use open-source code. And 11% of that has known vulnerabilities, making detection harder. To prevent attacks, we need broad strategies. These should find and fix vulnerabilities swiftly.
The use of shared software components also makes it tricky to spot and stop threats. A single hacked software can affect many companies, making the attack’s impact much greater. This shows why it’s crucial for businesses to keep strengthening their defenses and stay alert to new threats.
