The value of open source is undeniable — 90% of all modern software development depends on it. According to Harvard Business School, in 2024 alone, more than 6 trillion open source software components were downloaded, representing almost $9 trillion in value to users.
As a result, the security of open source software is a growing concern across the industry, particularly for federal agencies. The sophistication and frequency of cyber threats targeting open source dependencies are increasing, with high-profile attacks like SolarWinds and Log4j, demonstrating the potential impact.
This is putting pressure on developers whose responsibility it is to serve the public trust. In this blog, we discuss why addressing the malware threat in your supply chain is critical, including the risks malware represents, detection and mitigation strategies, and regulatory requirements to boost our cybersecurity posture.
Malware vs. Vulnerabilities: Understanding the Difference
Malware is designed intentionally to do harm by gaining unauthorized access or otherwise compromising systems. It has been with us for years, spreading through email attachments, malicious websites, or compromised devices. But in conjunction with the rise in the use of OSS components, we’ve seen the rise of open source malware, which is malware disguised as legitimate components to infiltrate repositories.
In contrast, a vulnerability is a weakness that can be exploited to gain unauthorized access to a system, cause damage, or manipulate it in some way. Vulnerabilities are not intentional but can leave a system vulnerable to attack.
Attackers are evolving from exploiting vulnerabilities to injecting malware directly into open source projects. This represents a particularly dangerous threat because it makes it possible for hackers to compromise OSS repositories and amplify the damage that can be done.
