Manual Extraction of Evidence from Thunderbird MBOX Files
Thunderbird data files are stored locally in the user machine with .mbox extension. These MBOX files have crucial importance to extract the evidential information regarding the conducted offense. The Thunderbird stores its email data in the MBOXRD file, a kind of MBOX file. The emails in an MBOXRD format file are stored in a simple MIME format. In Thunderbird, for each default mail folder, a corresponding MBOXRD file is created locally with the same file name as of the default mail folders.
For instance, the Inbox folder of Thunderbird creates with MBOXRD file format, named INBOX. It is to be noted that MBOXRD files do not possess any extension.
If we analyze more deeply, some user defined email folders like Sent Mail folder can be found under the .sbd folder.
Thunderbird IMAP mail data and profile can also be found in the folder named ImapMail.
On the other hand, the POP mail profile folder and local folders are stored in the Mail folder.
