Abstract
One or more techniques and/or systems are provided for file acquisition for reputation evaluation. A reputation service may be configured to evaluate files and provide reputations of such files to clients (e.g., an indication as to whether a file is safe or malicious). If the reputation service receives a reputation request for a file that is unknown to the reputation service (e.g., a file not yet fully acquired by the reputation service), then the reputation service may identify a set of chunks into which the file can be partitioned. The reputation service may obtain chunks from various clients, such as a first chunk from a first client and a second chunk from a second client. Such chunks may be evaluated to assign a reputation to the file. In this way, the reputation service may retrieve portions of a file in a distributed manner for reputation evaluation.
