Mozilla Thunderbird is a desktop-based email client which was released in the year 2004 and it has experienced vast growth in its user count. With such a rapid increment in the consumers, the number of illicit activities initiated by Thunderbird users has also increased. Therefore, to find suspects and prove them guilty in the court of law, the forensic analysis of Thunderbird emails came into force. Digital forensics examiners need to execute an in-depth analysis of the Thunderbird emails with the assistance of a proficient tool like Thunderbird email viewer.
MailXaminer is one of the efficient Thunderbird email examination software which is used to fetch out the evidence from Thunderbird emails. The Email Examiner Software primarily analyzes the data stored in the MBOX file of Thunderbird, which locally stores the Thunderbird emails. The robust and powerful mechanism of MailXaminer makes it possible to extract evidence from the corrupted or deliberately damaged MBOX file. It gives a detailed preview of the email data stored in the MBOX file. It facilitates the forensic investigators in carrying out a deep analysis of the source of the emails via email header analysis, attachments, and email body analysis.
Some of the exemplary features of Thunderbird email viewer software are as follows:
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.
Other important data files that store the information regarding Thunderbird emails include global-messages-sqlite.db file. This can be found at the location as shown in the screenshot. Thunderbird uses this file for indexing and to search for emails.
For each MBOXRD file, there exist some corresponding .msf files which are used for storing the indexed folders of Thunderbird in Mork format. This Mork format is used by Thunderbird for storing the data like an address book.
Manually extracting evidence from Thunderbird emails is a time consuming and a complete in-efficient task. Manual procedures do not guarantee complete recovery of artifacts and have a risk of missing crucial evidential information. Therefore, Thunderbird Email Viewer like MailXaminer is the first choice of forensic experts to yield maximum output in the investigation.
