Query: Get a Model! Model Hijacking Attack Against Machine Learning Models   Machine learning (ML) has established itself as a cornerstone for various
critical applications ranging from autonomous driving to authentication
systems. However, with this increasing adoption rate of machine learning
models, multiple attacks have emerged. One class of such attacks is training
time attack, whereby an adversary executes their attack before or during the
machine learning model training. In this work, we propose a new training time
attack against computer vision based machine learning models, namely model
hijacking attack. The adversary aims to hijack a target model to execute a
different task than its original one without the model owner noticing. Model
hijacking can cause accountability and security risks since a hijacked model
owner can be framed for having their model offering illegal or unethical
services. Model hijacking attacks are launched in the same way as existing data
poisoning attacks. However, one requirement of the model hijacking attack is to
be stealthy, i.e., the data samples used to hijack the target model should look
similar to the model's original training dataset. To this end, we propose two
different model hijacking attacks, namely Chameleon and Adverse Chameleon,
based on a novel encoder-decoder style ML model, namely the Camouflager. Our
evaluation shows that both of our model hijacking attacks achieve a high attack
success rate, with a negligible drop in model utility.
