Supply chain attacks are becoming increasingly common due to the complexity of modern software and its numerous dependencies, making it easier for attackers to inject malicious code into applications. These attacks often exploit vulnerabilities in third-party hardware, software, and services, and can be particularly difficult to foresee because vendors may not even know their own software has been compromised. Recent high-profile attacks on companies such as Solarwinds, Malwarebytes, and Mimecast demonstrate the widespread nature of this threat. The industry is responding with new regulations and best practices, including the implementation of Single Sign-On (SSO) solutions to provide additional layers of authentication and mitigate risks. Open-source software is also vulnerable to supply chain attacks, and companies must evaluate their trust in vendors and take steps such as requesting Software Bills of Materials and practicing dependency vendoring to reduce the risk. Ultimately, a collaborative and transparent approach is needed to address this growing threat, with companies trusting the community, sharing information about known or suspected attacks and vulnerabilities, and staying up-to-date with patches and security alerts.
