News for version 0.9.4

The new version is out with the following news:

added RTF support including OLE extraction and raw text preview
– added file times support and extraction in Zip archives
added disasm options to several engines
added support for Android Binary XML format
exposed several disasm engines as filters
– introduced metadata strings to SDK
– exposed Zip format class to Python
– fixed module initialization problem in the SDK

Some features planned for this release were postponed for the next version (or perhaps even the version after that), because too many unplanned new features have been introduced in 0.9.4. Some of the news above need further explanations and examples, but I’m afraid posts about them will have to wait. It would be nice to show some of these new features in conjunction with other features which are planned for the near future.

In the meantime we hope you enjoy the release!

News for version 0.9.3

The new version is out with the following news:

– subdivided the Python SDK into modules
exposed many core and file format classes to Python (part 2)
exposed filters to Python
introduced Python hooks
introduced Python key providers
– improved SDK documentation
added extensions view
added file formats scan option
added decryption keys view
– fixed occasional concurrency issue with large files
– fixed embedded files manual addition issue (affected versions: >= 0.9.1)

Most of the items in the list have been demonstrated in previous posts. The only addition left to discuss is the key dialog. When a file is encrypted and gets decrypted with a key either provided by the user or by a script, then this key ends up in a special list of matched keys. This list can now be inspected by the user.

If some files have been decrypted an additional “Decryption keys” button will be shown. Just click on it and you’ll get the list of matched keys.

That’s all. Enjoy!

News for version 0.9.2

The new version of the Profiler is out with the following news:

removed virtual memory constraint: large files are now supported
added decompression bomb detection
added media preview for image files
added preview for several PE resources
added text preview for Office Word Documents
added format selection to open file dialog
display format choose dialog when more than one format has been detected
added XFA interactive forms detection inside PDFs
added from/to hex and base64 filters
automatically detect files in Zip archives missing a Central Directory
increased PySide integration
– fixed Office VBA extraction bug
– fixed bug in PDF V4 and V5 Revision encryption

Format detection & selection

To better help with the identification of files which can be interpreted as different formats, the individual file dialog features now some additions.

As you can see the identified formats for the currently selected file are listed (it’s a simple GIF file with a PDF appended at the end). The dialog gives the user also the ability to manually choose the format to use for loading the file. While all this could be achieved even before, it wasn’t as handy as it is now.

However, it wouldn’t make sense to display the file selection dialog when the user uses the shell integration or drops a file to open it. So, instead the Profiler displays a choice dialog for the format in case multiple formats are detected.

Conversion filters

Some new filters are available: from/to hex/base64.

While the actions in the Profiler already feautured a mechanism to do these conversions, having them as filters is extremely useful, because it allows to use them to load embedded files or to convert large portions of data.

Damaged Zip archives

While it has always been possible to manually extract through filters data or partial data from damaged Zip files (e.g. those missing a Central Directory), now the embedded data is automatically analyzed and ready for inspection. This means that even when a Zip archive is truncated and some compressed files are truncated as well, they will nonetheless be automatically detected and be available for inspection by the user.

As you can see many improvements have been introduced. The most important of them is of course the removal of the virtual memory constraints as it represents an important step in the roadmap of the Profiler. Stay tuned as the next version will be important as well!

News for version 0.9.1

The new version of the Profiler is out with the following news:

added capability of opening multiple analysis views
added capability of switching root object in the workspace
added navigation in analysis views
added bookmarks
added PySide integration
– added user application data folder support
– added history for the Python command line and script dialog
– added save option to the keys input dialog
– improved notes: the toolbar now signals their presence
– updated Qt to 4.8.4

Also a new Demo version has been released, which as usual can be found on the product page.

News for version 0.9.0

We’d like to wish everybody merry Christmas and a happy new year!

We’re just in time to place under the Christmas tree a new version of the Profiler with the following news:

added Java Class support including byte code disassembler and layout ranges
added .NET support including byte code disassembler and layout ranges
added DEX support including byte code disassembler and layout ranges
added dedicated view to display data like raw PDF objects
added PE MUI resources validation
– added Adler32 to filters
– updated jsbeautifier
separated malicious threats from intrinsic ones in the report view
– fixed update with unprivileged user account on Windows
– fixed several bugs

The main addition in this new release as seen previously is the managed trio Java, DEX and .NET.

Dedicated view to display raw data

Previously PDFs had 3 views to display objects: one for the dictionary, one for the decoded stream and one for the decoded stream shown as text. Now there’s also a ‘raw data’ view to show the object unmodified just as it is in the file.

Highlighted with different colors you can see the dictionary/value and the stream part. The same applies to child objects which are highlighted in the stream of their parent.

PE MUI resources validation

Following a short post about MUI resources, validation for them has been added. Also some bug fixes related to resource validation.

Separated malicious threats from intrinsic ones

In order to better separate intrinsic risk factors from malicious threats, they are now shown separately in the report view.

Have some nice holidays and stay tuned as we’ll try to add even more features the upcoming year.

News for version 0.8.9

The new version is out. 🙂 Here’s a recap of the latest improvements:

increased python integration and exposed more parts of the SDK
– added SDK documentation to the docs directory
– added Python command line
– added global and individual file notes
improved filters and added range parameters
– introduced fullscreen modality in workspace (F11)

This has been mostly a transition release and what took most of the time were structural changes in how the SDK is exposed to Python so that future releases will benefit from it. The main advantage for the user may be the addition of range parameters in the filters and the introduction of file notes, which is a small feature, but very useful in the context of analysis.

The next release will bring some new file formats and interesting improvements.

News for version 0.8.8

While we talked about some of the news of this version, there are some more which are worth mentioning.

introduced new multi-file report and project technology with compression and encryption
introduced new UI for workspace mode
added Windows Lnk support
– added file extensions scan option
– added directory scan to command line
added PNG CRC validation
added new filters: misc/replace and dev/array
– several UI improvements
– hex editor improvements
– increased memory limit

New workspace UI

The workspace features a new dock-based UI. It is easy to get used to the new UI as it is completely intuitive.

Workspace UI

Now our users can completely costumize their analysis workspace.

PNG CRC validation

This feature was requested by one of our customers and it can come handy during forensic analysis. The CRC of each PNG chunk is verified and those which don’t match are signaled in the format view (highlighted in red).

PNG CRC

New filters: misc/replace and dev/array

Two new filters have been added. misc/replace is self explanatory: it replaces bytes and strings. While dev/array is a small addition which can come handy all those times we need to copy some bytes to an array in a programming language. We can specify the language, the radix and the number of columns and we get something like:

We hope you enjoy this new version.

News for version 0.8.5

Since there are many improvements and additions, here’s a list with the most important ones:

– finished support for Portable Executable directories (.NET excluded): Delay Import, Bound Import, Exception (x64, IA64), Security
– improved detection of files in MSI archives
– replaced the native scan table with the custom table control: now it’s fast and efficient
– added threat highlighting and jump in scan table and hierarchy view
– increased the UI responsiveness during batch scans
– introduced option to disable intrinsic risk factors
– added search functionality to every control which lacked it
– added support for PNG and APNG files
– added support for GIF files
– improved PE Debug directory view
– added language switch in text view
– improved file format choose dialog
– improved initialization performance by delay-loading some modules
– updated OpenSSL

This version prepares the ground for the next .6 version, which as I expect will be very interesting. However, even in 0.8.5 there are many useful new things, so in this post I’ll just do a tour of those which might need an explanation.

Threat highlighting

This means that files with a risk factor > 0 are now highlighted with different gradients of orange (low risk) and red (high risk). This is true for the new file system scan results table, which by the way is now blazingly fast.

Scan threat highlighting

But also for the file hierarchy itself.

Hierarchy threat highlighting

It’s possible to jump to files with risk factor > _customizable_threshold_limit_ with F2 (next) and Shift+F2 (previous).

Disable intrinsic risk factors

It’s pretty clear that an executable can contain native code, right? It’s expected to, just as a font file is expected to contain its specific bytecode. These characteristics are intrinsic to these file formats and as users we might not desire to be alarmed by that.

Disable intrinsic risk

By enabling this new handy option, these factors will no longer contribute to calculate the risk of a file.

PE directories

Apart from .NET, all Portable Executable directories are now supported. Specifically, support for the following directories has been added: Delay Import, Bound Import, Exception (x64, IA64) and Security.

Security Directory

This month we will post about some new interesting features and the PE analysis series will be continued. 🙂
