You Can't Reverse Engineer Your Way Out of the AI Supply Chain Problem
Blog post from Semgrep
Modern AI models, including open-source and proprietary frontier models, present significant challenges in terms of transparency and trust, as their inner workings remain largely inscrutable compared to traditional software. This lack of mechanistic interpretability makes it difficult to predict model behavior or detect potential backdoors—malicious manipulations that can subtly influence outputs—introduced during training or fine-tuning. While no public evidence currently suggests widespread deliberate poisoning of open-source models, the risk of such compromises remains a concern, as they can lead to biased recommendations or insecure outputs that are hard to trace back to the model itself. The industry's reliance on benchmarks and marketing claims for assessing model reliability is insufficient; instead, a robust ecosystem involving trusted third parties for independent evaluation, provenance tracking, and transparency at every development stage is necessary to build trust in AI technologies. This situation mirrors Ken Thompson's insights on the importance of understanding the full lineage and development process of systems to ensure their security and reliability.
