News for version 0.9.7

The new 0.9.7 version of the Profiler is out with the following news:

introduced C++ class/struct parsing with Clang
introduced headers, layouts and manual analysis in hex mode
exposed all the above to the Python SDK
added capability to turn into a portable application
– added SHA-3 hashes
– updated Qt to 4.8.5
– updated OpenSSL
– behavior change: displaying table flags now requires a double click

Enjoy!

News for version 0.9.6

The new 0.9.6 version of the Profiler is out. The main new feature is the support for Mach-O files. Since this feature stands on its own, it did make sense to postpone other features to the next version and in the meanwhile let our users benefit from this addition.

Here’s the changelist:

added support for Mach-O files
added support for fat/universal binaries
added support for Apple code signatures
– exposed DemangleSymbolName to Python

The DemangleSymbolName function demangles both VC++ and GCC symbols. Its use is straightforward:

News for version 0.9.5

We’re happy to present to you the new version of the Profiler with the following news:

introduced Lua filters: lua/custom and lua/loop
added optional condition to misc/basic
added JavaScript execute action
added JavaScript debugger
– simplified save report/project logic
– included actions among the extensions views
– improved detection of shellcodes
introduced max file size option for shellcode detection
improved OLE Streams parsing and extraction from RTFs
exposed getHash method in ScanProvider to Python
– added text replace functionality to text controls

While most of the items in the list have been discussed in previous posts, some of them need a brief introduction.

Max file size for shellcode detection

While shellcode detection applies by default to files of any size, you might want to specify a threshold.

Shellcodes scan options

This is useful if you want to speed up the analysis of large files. It might come handy in some cases.

The ‘getHash’ method

This method should be used by hooks to retrieve a hash for the currently scanned file. The syntax is very simple:

Of course one could use a filter to hash the file, but the advantage of this method is that once a particular hash type has been computed it won’t be computed again if requested by another hook.

Improved OLE Streams parsing and extraction from RTFs

In one of the previous use cases we’ve analyzed a huge set of malicious RTF documents. Some of them were not recognized correctly and some of them showed problems in the automatic extraction of OLE streams. This release fixes these issues.

RTF set

As you can see all RTFs are now correctly parsed and their OLE stream has been extracted. Some of the OLE objects though are not extracted correctly. After looking into it, it seems to be a problem with the malicious files themselves. OLE streams are encoded as hex strings into the RTF and in some of these files there’s an extra byte which invalidates the sequence.

That ‘A’ character between 00 and 4D makes the sequence to be 00 A4 D which is incorrect. Our guess is that the malware generator which produced these RTFs outputted some invalid ones by inserting an ‘A’ character instead of a 0x0A newline.

While RTF readers are not able to parse these objects either it’s still interesting for our analysis to be able to inspect them. So we just load the RTF files patching the ‘A’ character with a filter as in the screenshot below.

Fixing a broken OLE stream

That fixes it and we are now able to inspect the embedded OLE object and its threats. As you can see we get directly the shellcode disassembly from the automatic analysis.

Fixed OLE stream

Enjoy!

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.
