Detecting Malicious Packages and How They Obfuscate Their Malicious Code
Blog post from JFrog
The final entry in the Malicious Packages blog series explores the intricacies of software supply chain attacks, focusing on the stealthy techniques attackers use to integrate and conceal malicious code within software packages. The series covers the role of such packages in attacks, the infection methods, and the execution of payloads to achieve attackers' goals, including employing obfuscation techniques like base64 encoding, control flow flattening, and the use of homoglyph and bidirectional control characters. It discusses the detection of both known and unknown malicious packages, emphasizing the limitations of relying solely on public repositories and the need for advanced heuristic scanning tools like JFrog Xray. The series concludes with best practices for secure development, advocating for the use of software composition analysis tools, defining DevSecOps policies, and employing open-source tools to mitigate threats.
