Epilog customers: a software tease

Here at CCL-Forensics, we like to tease our software customers from time to time with the promise of future goodies.

The R&D team has been beavering away on a number of projects recently, including making improvements and adjustments to our existing software.

Our epilog users will doubtless be excited to learn that version 1.1 is nearly ready for release. It’s being beta-tested as you read this, so it should soon be winging its way to existing users as a free upgrade, and will be available for new users to purchase.

So what’s new?

Well, first off: epilog 1.1 includes a database rebuilder. For analysts with tools and scripts designed only to operate on live data, this will be a sanity saver. It’s an integrated solution for rebuilding recovered records into a copy of the live database, enabling deleted data to be parsed or processed.

It also allows the user to choose whether to include the current live records, options to disable triggers and remove constraints from the database schema to tailor the rebuilding.

We’ve been keeping up with new developments in the world of SQLite. Version 3.7 of the SQLite library introduced a new journal format called “Write Ahead Log” or WAL. The new version of epilog will permit WAL file parsing. It differs from the traditional journal mechanism in that it writes new data into a separate file when specifically asked to by the database engine, rather than backing up data to a rollback journal.

In epilog 1.1 the requirement for an “associated database” when conducting a raw data or disk image search has been removed, and instead the user can provide the database page seize and text encoding manually (the option to use an associated database is still available for when it’s more convenient). There are also extra options for improving results when reading from raw dumps from flash chips.

Epilog 1.1 will now mark in grey records that have been recovered but which are truncated; this allows the user to make more informed decisions about the data. We’ve also improved the signature search algorithm to remove the need for “in the case of multiple concurrent deletion” signatures.

New export modes have been added, allowing users to output to a flat tab separated values (tsv) file. The “INSERT export” has been overhauled to make it more convenient to use.

And finally, what was formerly the “Table Analysis” feature has been upgraded to “Database and Table Details” and now reports further information regarding the database structure and parameters.

So, we’ve been pretty busy working on epilog and have taken on board the feedback we’ve received. We’re always happy to receive comments and suggestions, so please feel free to get in touch either by leaving a comment below, or emailing epilog@ccl-forensics.com.

Forensic software tools – get ‘em while they’re hot, they’re lovely!

The R&D team at CCL-Forensics are a busy bunch. Over the past couple of years, they’ve developed a number of forensic software tools to examine the evidence that standard tools can’t reach.

Here’s a quick overview of what’s on offer. Follow the links to find out more, or give us a shout by phone (01789 261200) or email (info@ccl-forensics.com) – we’re always happy to talk geek with like-minded practitioners.

epilog allows investigators to recover deleted data from SQLite databases, a widely-used format in many devices including mobile phones, computers and SatNavs). Many off-the-shelf tools will only allow you to view live records.

PIP is our XML and plist parsing tool. It allows investigators to present often-complex data from XML files quickly, efficiently, and in a user-friendly format. Apple’s property list files – both XML and binary formats – present no obstacle to PIP at all.

dunk! is a splendidly-named tool for digging around in cookies. Unlike standard tools, it analyses known cookie types to uncover potential new evidence and help give context to other browser artefacts. This includes showing the path the user took to arrive at a particular webpage by parsing Google Analytics cookies, revealing a wealth of information previously unavailable to practitioners.

rubus  is FREE! We like to give a little love back to the community, so with this in mind, we made our BlackBerry backup deconstruction tool available. Not having found a tool that would do the job, we made our own – enabling analysts to reverse engineer BlackBerry backup data stored in .ipd files.

The tools all went through beta-testing first, and were pronounced ready to unleash upon the world. Since then, they’ve been subject to an introductory pricing period, and have been bought and used successfully around the world.

Now that we’re confident in the tools we’ve developed, we’re also confident in their value to our customers. So with that in mind, if you haven’t bought the tools already, you may want to think about doing so! The introductory pricing period finishes at the end of March – and although they’ll still be extremely good value for money, they will be a little more expensive.

We’ve had useful feedback from our customers in the past, which has helped us to further develop our tools, and we always welcome comments and suggestions on our software. Feel free to comment below, or get in touch with us in more traditional ways!
