Software supply chain attacks more than tripled in 2021

Aqua Security has released results from a study conducted by experts from recently acquired Argon Security, which found that software supply chain attacks grew by more than 300 percent in 2021 compared to 2020.

According to Argon’s 2021 Software Supply Chain Security Review, researchers discovered attackers focused most heavily on open source vulnerabilities and poisoning, code integrity issues, and exploiting the software supply chain process and supplier trust to distribute malware or backdoors. They found that the level of security across software development environments remains low, and significantly, every company evaluated had vulnerabilities and misconfigurations that can expose them to supply chain attacks.

Findings were based on a six-month analysis of customer security assessments conducted by Argon’s researchers to determine the state of enterprise security and readiness to defend against software supply chain attacks.

The Argon study identified three primary areas of risk that companies should understand and address to improve software supply chain security:

Vulnerable packages usage: open source code is part of almost all commercial software. Many of the open source packages in use have existing vulnerabilities, and the process of upgrading to a more secure version requires effort from development and DevOps teams. It is not surprising that this is one of the fastest-growing methods of carrying out supply chain attacks. There are two common attacks that leverage vulnerable packages:

Compromised pipeline tools: attackers can take advantage of privileged access, misconfigurations, and vulnerabilities in the CI/CD pipeline infrastructure (e.g., source code management system, build agent, package registries and service dependencies), which provide access to critical IT infrastructure, development processes, source code and applications. A compromised CI/CD pipeline can expose an application’s source code, which is the blueprint of the application, the development infrastructure and processes. It enables attackers to change code or inject malicious code during the build process and tamper with the application (e.g., SolarWinds). This type of breach is hard to identify and can cause a lot of damage before it is detected and resolved. Attackers also use compromised package registries to upload compromised artifacts instead of legitimate ones. In addition, there are dozens of external dependencies connected to the pipeline that can be used to access it and launch attacks (e.g., Codecov).

Code/artifact integrity: one of the main risk areas identified in Argon’s research is the upload of bad code to source code repositories, which directly impacts the artifact quality and security posture. Common issues that were found in most customer environments were sensitive data in code (secrets), code quality and security issues, infrastructure as code issues, container image vulnerabilities and misconfigurations. In many cases the number of issues discovered were overwhelming and required dedicated cleanup projects to reduce exposure, such as secret cleaning, standardizing container image and others.
