General Abnormal Patterns of Structure and Behavior (Part 0)

Tuesday, January 29th, 2013

Memory Analysis Patterns (MAPs) including memory dump, malware, software trace (TAPs), and other patterns and pattern catalogs from Software Diagnostics Institute form the very rich semantic network. Now it is possible (by using a metaphorical bijection) to create a catalog of General Patterns of Abnormal Structure and Behaviour including software, hardware, biological behavior including animal (ethology) and human behavior, sociological and historical behavior including economics, business and finance, ethics and law, and even behavior of chemical and physical systems. Such “GAPs of Structure and Behavior” may include wait chains, spikes, deadlocks, etc. We provide more specific examples in the forthcoming parts. So we are a few steps closer to realization of my old dangerous idea of a parameterized science of universal memory dumps by the so called science files or might event a general diagnostics discipline.

On Matter and Substances

Wednesday, January 23rd, 2013

What is a role of perceived memory deficient matter in Memorianity where Memory consists of memories (Memorianic Prophecy 0m3)? Matter are boundaries of memories as illustrated on this schematic diagram:

We can also reverse monistic aspect pluralism of Memoidealism and consider substances as boundaries of memories too.

DD That (Debugging Slang, Part 37)

Tuesday, January 22nd, 2013

I don’t know how I missed it. It was the first real life slang I heard almost 10 years ago during hot political and critical crash dump analysis session.

DD That - Analyze that simply.

Although more correctly would be to say DP That at that time when I heard it 64-bit computing wasn’t a mainstream yet. Based on dd WinDbg command to dump raw binary data starting from a given 32-bit memory address.

Examples: I dd-ed that and found an ASCII.

STATUS (Debugging Slang, Part 36)

Tuesday, January 22nd, 2013

STATUS - Something important to check for just now.

Examples: If only programmers checked statuses of their functions more often than statuses on Facebook…

Malware Analysis Patterns (Part 11)

Sunday, January 20th, 2013

Injected code address may not be in the address ranges of loaded modules. In such cases, in the execution call history we would see plain EIP and RIP return addresses on stack traces. We call this pattern RIP Stack Trace partly because we have seen these addresses after something had gone wrong and a process crashed:

Malware Analysis Patterns (Part 10)

Sunday, January 20th, 2013

We skip parts 5 (Module Collection), 6 (No Component Symbols, for looking at import tables), 7 (Stack Trace Collection, for listing active processes, threads and their stack traces), 8 (Hidden Module), and 9 (Hidden Process). The new pattern here is called Driver Device Collection and can be used to compare the current list of device and driver objects with some saved reference list to find out any changes. This listing can be done by using !object command:

0: kd> !object \Driver
[...]

0: kd> !object \FileSystem
[...]

0: kd> !object \Device
[...]

Note that the collection is called Driver Device and not Device Driver.

The next pattern is closely linked to packed and/or obfuscated code. We call it Pre-Obfuscation Residue. Depending on a level of obfuscation and/or packing some initial code and data structures and patterns including fragments of strings may leak in post-obfuscation data giving a clue to intended software behavior:

Crash Dump Analysis Patterns (Part 194)

Friday, January 18th, 2013

Whereas some false positives can be considered soft debugger bugs false negatives can have more severe impact on software behavior analysis especially in malware analysis. We name this pattern Debugger Omission. Typical example here is current .imgscan command which according to documentation should by default scan virtual process space for MZ/PE signatures. Unfortunately it doesn’t detect such signatures in resource pages (we haven’t checked stack regions yet):

Holes of Infinity

Tuesday, January 15th, 2013

The new SF novella to be published this year: Holes of Infinity (ISBN 978-1-908043436). Book description:

The year 1000001. Intergalactic flight is in deep past. Humans switch between holes on manifold computers to navigate through parallel universes. Some universes are fine-tuned for usage as a library storage and others as universal computers. A researcher finds an ancient desktop machine description in one of the universal libraries and builds a working copy.  Fascinated by the ability of ancients to switch between windows to navigate through different views of the same data the researcher discovers a long sought fine-tuning constant that will transform one of universes into a world suitable for colonization. A new era begins…

Software Disruption Patterns (Part 1)

Saturday, January 12th, 2013

These are not really testing patterns but patterns of a user or program behaviour resulting in abnormalities such as colored screens (blue and grey), crash dumps and other support artefacts including performance alerts and UI problem patterns. The first such pattern is called Space Precondition. It is often a case that a process checks for free disk space before proceeding, for example, with updates. This precondition may be violated by a user filling disk after the check but before or during installation. Such was the case with our recent Mac OS X update where we did some copying in the background while the update was downloaded that resulted in insufficient space after reboot, then a grey screen after that and subsequent disk corruption and finally reinstalling OS and loss of several hours better spent with other pattern categories.

Holes Infinity (HI OS)

Saturday, January 12th, 2013

An operating system for inter-universe flight in year 1000001. Simple inter-galactic space flight was already achieved in deep past. Its operating system name was lost.

Disclaimer: Due to so distant future no connection with existing current operating systems is assumed.

Static Code Analysis Patterns (Part 1)

Friday, January 11th, 2013

Static program analysis is used to eliminate certain coding errors that may lead to abnormal software behaviour. So it is naturally a part of software diagnostics but at source code level. Our goal here is to identify certain patterns directly linkable to patterns we see in memory dumps and software logs and collect them into a catalog. One such pattern candidate is called Loop Construct. It covers conditional and unconditional loops, for example, in one of modern languages:

extern bool soonToBeTrue; 
int mediumValue = ...;
while (true)

{

  TRACE("Waiting");

  sleep(mediumValue);

  if (soonToBeTrue)

  {

    break;

  }

  doHeavyWork();

}
while (--pControl->aFewPasses)

{

  TRACE("Waiting");

  sleep(mediumValue);

  doHeavyWork();

}

Such loops may potentially lead to Spiking Thread memory dump analysis and High Message Current and Density trace analysis patterns. Of course, we shouldn’t suspect every loop but only some that have potential to be altered by Local Buffer Overflow (for mediumValue) or Shared Buffer Overwrite (for Control.aFewPasses) or by a race condition (soonToBeTrue).

We expect things to get more interesting when we start associating source code that uses certain API with patterns of abnormal behavior.

Process Monitor as Modeling Tool

Wednesday, January 9th, 2013

If you need to get various real life software traces with millions of lines from complex software environments to learn pattern-driven software log analysis you can us Process Monitor as a modeling tool. Here you can abstract from their “monitoring” and API interception context and consider trace messages as emitted from various processes and threads (like Citrix CDF traces). This approach was used in Accelerated Windows Software Trace Analysis training and Debugging TV Frames episode 0×19.

Crash Dump Analysis Patterns (Part 193)

Wednesday, January 9th, 2013

Sometimes we have a Broken Link for some reason, either from memory corruption, Lateral Damage or Truncated Dump. For example, an active process list enumeration stops after showing some processes (!for_each_thread and !vm also don’t work):

0: kd> !process 0 ff

[...]

TYPE mismatch for process object at fffffa80041da5c0

0: kd> !validatelist nt!PsActiveProcessHead
Blink at address fffffa80041da748 does not point back to previous at fffffa8005bc8cb8

Here we can either try to repair or navigate links manually or use other means such as dumping pool allocations for process structures with Proc pool tag:

0: kd> !poolfind Proc

Searching NonPaged pool (fffffa80032fc000 : ffffffe000000000) for Tag: Proc

A page to reference all different kinds of process related patterns is necessary, so I created this post:

I’ll update it as soon as I add more similar patterns.

Crash Dump Analysis Patterns (Part 13i)

Saturday, January 5th, 2013

Although we briefly mentioned session pool in Insufficient Memory (kernel pool) pattern we decided to factor it into a separate (sub)pattern and provide WinDbg commands to analyze possible leaks. The following output shows the sequence of commands that gives you an idea although the example itself was taken from a healthy dump so no red coloring (from my memory leaks in session pool happened mostly in 32-bit past):

1: kd> !vm 4

Terminal Server Memory Usage By Session:

Session ID 0 @ fffff8800324d000:
Paged Pool Usage:        4128K
Commit Usage:            7488K

Session ID 1 @ fffff88002f65000:
Paged Pool Usage:       32852K
Commit Usage:           36488K

1: kd> !session
Sessions on machine: 2
Valid Sessions: 0 1

2008-2012 in Retrospection

Friday, January 4th, 2013

Before deciding on whether to retrospect on 2012 we found that since March 14, 2008 this site has had more than 1 million visitors with more than 33% returning. So instead of just 2012 we decided to retrospect on that interval up to December 31, 2012. Google Analytics has improved since last January, 2012 and now made our task easier. So we start with the first one hundred sites referring to us:
