Exif Smuggling: PoC for Hiding Malicious Prompts in Image EXIF Metadata
Original: Exif Smuggling
A proof-of-concept tool demonstrating how malicious instructions can be smuggled into image EXIF metadata to attack multimodal AI systems via prompt injection.
Exif Smuggling is a security PoC showing how attackers can embed hidden instructions in image EXIF metadata fields to perform indirect prompt injection against vision-capable AI models. When AI systems parse images alongside their metadata, embedded malicious text may be processed as legitimate instructions, bypassing standard input filters. Developers building AI apps with image upload features should strip or sanitize EXIF data before passing content to language models.
「Exif Smuggling」是由安全研究者 signalblur 在 GitHub 發布的概念驗證(Proof of Concept)專案,核心議題是利用圖片檔案的 EXIF 元資料作為載體,對多模態 AI 系統執行提示注入(Prompt Injection)攻擊。
