Autopsy® is a digital forensics platform and graphical interface to The Sleuth Kit® and other digital forensics tools. It can be used by law enforcement, military, and corporate examiners to investigate what happened on a computer. You can even use it to recover photos from your camera's memory card.
Analysis Features
Below is the list of Autopsy features.
- Timeline Analysis: Displays system events in a graphical interface to help identify activity.
- Keyword Search: Text extraction and index searched modules enable you to find files that mention specific terms and find regular expression patterns.
- Web Artifacts: Extracts web activity from common browsers to help identify user activity.
- Registry Analysis: Uses RegRipper to identify recently accessed documents and USB devices.
- LNK File Analysis: Identifies short cuts and accessed documents
- Email Analysis: Parses MBOX format messages, such as Thunderbird.
- EXIF: Extracts geo location and camera information from JPEG files.
- File Type Sorting: Group files by their type to find all images or documents.
- Media Playback: View videos and images in the application and not require an external viewer.
- Thumbnail viewer: Displays thumbnail of images to help quick view pictures.
- Robust File System Analysis: Support for common file systems, including NTFS, FAT12, FAT16, FAT32, HFS+, ISO9660 (CD-ROM), Ext2, Ext3, and UFS from The Sleuth Kit.
- Hash Set Filtering: Filter out known good files using NSRL and flag known bad files using custom hashsets in HashKeeper, md5sum, and EnCase formats.
- Tags: Tag files with arbitrary tag names, such as 'bookmark' or 'suspicious', and add comments.
- Unicode Strings Extraction: Extracts strings from unallocated space and unknown file types in many languages (Arabic, Chinese, Japanese, etc.).
Input Formats
Autopsy analyzes disk images, local drives, or a folder of local files. Disk images can be in either raw/dd or E01 format. E01 support is provided by libewf.
Reporting
Autopsy has an extensible reporting infrastructure that allows additional types of reports for investigations to be created. By default, an HTML, XLS, and Body file report are available. Each are configurable depending on what information an investigator would like included in their report:
- HTML and Excel: The HTML and Excel reports are intended to be fully packaged and shareable reports. They can include references to tagged files along with comments and notes inserted by the investigator as well as other automated searches that Autopsy performs during ingest. These include bookmarks, web history, recent documents, keyword hits, hashset hits, installed programs, devices attached, cookies, downloads, and search queries.
- Body File: Primarily for use in timeline analysis, this file will include MAC times for every file in an XML format for import by external tools, such as mactime in The Sleuth Kit.
An investigator can generate more than one report at a time and either edit one of the existing or create a new reporting module to customize the behavior for their specific needs.
