Understanding Prompt Injection: Risks, Methods, and Defense Measures
TL;DR Prompt injection, a security vulnerability in LLMs like ChatGPT, allows attackers to bypass ethical safeguards and generate harmful outputs. It can take forms like direct attacks (e.g., jailbreaks, adversarial suffixes) or indirect attacks (e.g., hidden prompts in external data). Defending against prompt injections involves prevention-based measures like paraphrasing, retokenization, delimiters, and instructional safeguards. However, detection-based strategies include perplexity checks, response analysis, and known answer validation. Some advanced tools also exist such as prompt hardening, regex filters, and […]
