Elcomsoft Phone Password Breaker Enhances iCloud Forensics and Speeds Up Investigations

Thursday, August 22nd, 2013

It’s been a while since we updated Elcomsoft Phone Password Breaker, dedicating our efforts to physical acquisition of iOS devices instead. Well, now when the new iOS Forensic Toolkit is out, it is time to update our classic phone recovery tool.

The new version of Elcomsoft Phone Password Breaker is released! While you can read an official press-release to get an idea of what’s new and updated, you may as well keep reading this blog post to learn not only what is updated, but also why we did it.

Dedicated to iCloud Forensics

This new release is more or less completely dedicated to enhancing support for remote recovery of iOS devices via iCloud. Why do it this way?

Because iCloud analysis remains one of the most convenient ways to acquire iOS devices. You can read more about iCloud analysis in a previous post here. Let’s see what else is available.

iCloud backups inside out

Monday, February 25th, 2013

It’s been a while since we released the new version of Elcomsoft Phone Password Breaker that allows downloading backups from iCloud (read the press release). Many customers all over the world are already using this new feature intensively, but we still get many questions about its benefits, examples of cases when it can be used and how to use it properly. We also noticed many ironic comments in different forums (mostly from users without any experience in using iOS devices and so have no idea what iCloud backups actually are, I guess), saying that there is nothing really new or interesting there, because anyone with Apple ID and password can access the data stored in iCloud backup anyway.

Well, it seems some further explanation is needed. If you are already using EPPB (and this feature in particular) you will find some useful tips for future interaction with iCloud, or even if you don’t have an iOS device (you loser! just kidding :) ) please go ahead and learn how iCloud can be helpful and dangerous at the same time.

Accelerating Password Recovery: the Addition of FPGA

Tuesday, July 17th, 2012

Back in 2008, ElcomSoft started using consumer-grade video cards to accelerate password recovery. The abilities of today’s GPU’s to perform massively parallel computations helped us greatly increase the speed of recovering passwords. Users of GPU-accelerated ElcomSoft password recovery tools were able to see the result 10 to 200 times (depending on system configuration) sooner than the users of competing, non-accelerated products.

Today, ElcomSoft introduced support for a new class of acceleration hardware: Field Programmable Gate Arrays (FPGAs) used by Pico Computing in its hardware acceleration modules. Two products have received the update: Elcomsoft Phone Password Breaker and Elcomsoft Wireless Security Auditor, enabling accelerated recovery of Wi-Fi WPA/WPA2 passwords as well as passwords protecting Apple and Blackberry offline backups. In near future, Pico FPGA support will be added to Elcomsoft Distributed Password Recovery.

With FPGA support, ElcomSoft products now support a wide range of hardware acceleration platforms including Pico FPGA’s, OpenCL compliant AMD video cards, Tableau TACC, and NVIDIA CUDA compatible hardware including conventional and enterprise-grade solutions such as Tesla and Fermi.

Hardware Acceleration of Password Recovery
Today, no serious forensic user will use a product relying solely on computer’s CPU. Clusters of GPU-accelerated workstations are employed to crack a wide range of passwords from those protecting office documents and databases to passwords protecting Wi-Fi communications as well as information stored in Apple and BlackBerry smartphones. But can consumer-grade video cards be called the definite ‘best’ solution?

GPU Acceleration: The Other Side of the Coin
Granted, high-end gaming video cards provide the best bang for the buck when it comes to buying teraflops. There’s simply no competition here. A cluster of 4 AMD or NVIDIA video cards installed in a single chassis can provide a computational equivalent of 500 or even 1000 dual-core CPU’s at a small fraction of the price, size and power consumption of similarly powerful workstation equipped only with CPU’s.

However, GPU’s used in video cards, including enterprise-grade solutions such as NVIDIA Tesla, are not optimized for the very specific purpose of recovering passwords. They still do orders of magnitude better than CPU’s, but if one’s looking for a solution that prioritizes absolute performance over price/performance, there are alternatives.

 How Would You Like Your Eggs?
A single top of the line video card such as AMD Radeon 7970 consumes about 300 W at top load. It generates so much heat you can literally fry an egg on it! A cluster of four gaming video cards installed into a single PC will suck power and generate so much heat that cooling becomes a serious issue.

Accelerating Password Recovery with FPGAs
High-performance password cracking can be achieved with other devices. Field Programmable Gate Arrays (FPGAs) will fit the bill just perfectly. A single 4U chassis with a cluster of FPGA’s installed can offer a computational equivalent of over 2,000 dual-core processors.

The power consumption of FPGA-based units is dramatically less than that of consumer video cards. For example, units such as Pico E-101 draw measly 2.5 W. FPGA-based solutions don’t even approach the level of power consumption and heat generation of gaming video cards, running much cooler and comprising a much more stable system.

GPU vs. FPGA Acceleration: The Battle
Both GPU and FPGA acceleration approaches have their pros and contras. The GPU approach offers the best value, delivering optimal price/performance ratio to savvy consumers and occasional users. Heavy users will have to deal with increased power consumption and heat generation of GPU clusters.

FPGA’s definitely cost more per teraflop of performance. However, they are better optimized for applications such as password recovery (as opposed to 3D and video calculations), delivering significantly better performance – in absolute terms – compared to GPU-accelerated systems. FPGA-based systems generate much less heat than GPU clusters, and consume significantly less power. In addition, an FPGA-based system fits perfectly into a single 4U chassis, allowing forensic users building racks stuffed with FPGA-based systems. This is the very reason why many government, intelligence, military and law enforcement agencies are choosing FPGA-based systems.

Explaining that new iCloud feature

Tuesday, May 29th, 2012

It’s been almost two weeks since we have released updated version of Elcomsoft Phone Password Breaker that is capable of downloading backups from the iCloud and we have seen very diverse feedback ever since. Reading through some articles or forum threads it became quite evident that many just do not understand what we have actually done and what are the implications. So I am taking another try to clarify things.

Let’s play a game! Rules are simple – just try to catch as much apples as you can into your police cap. Good catchers will get 25% discount for the new version of Elcomsoft Phone Password Breaker. Your challenge is just 100 apples, so let’s play! :)

ElcomSoft Helps Investigate Crime Providing Yet Another Way to Break into iOS with iCloud Attack

Tuesday, May 15th, 2012

 

Elcomsoft Phone Password Breaker and Elcomsoft iOS Forensic Toolkit have been around for a while, acquiring user information from physical iPhone/iPad devices or recovering data from user-created offline backups. Both tools required the investigator to have access to the device itself, or at least accessing a PC with which the iOS device was synced at least once. This limited the tools’ applications to solving the already committed crime, but did little to prevent crime that’s just being planned.

The new addition to the family of iOS acquisition tools turns things upside down. Meet updated Elcomsoft Phone Password Breaker – a tool that can now retrieve information from suspects’ phones without them even noticing. The newly introduced attack does not need investigators to have access to the phone itself. It doesn’t even require access to offline backups produced by that phone. Instead, the new attack targets an online, remote storage provided by Apple. By attacking a remote storage, the updated tool makes it possible watching suspects’ iPhone activities with little delay and without alerting the suspects. In fact, the tool can retrieve information from the online storage without iPhone users even knowing, or having a chance to learn about the unusual activity on their account. (more…)

New Features in EPPB

Thursday, April 5th, 2012

When it comes to adding new features to our products we try to focus on our customers’ needs and it is my pleasure today to announce a preview (or beta) version of our Phone Password Breaker tool with new features requested (or inspired) by our valued customers users :)

Here’s the wrap-up of new features.

Mobile password keepers don’t keep the word

Friday, March 16th, 2012

We’ve analyzed 17 popular password management apps available for Apple iOS and BlackBerry platforms, including free and commercially available tools, and discovered that no single password keeper app provides a claimed level of protection. None of the password keepers except one are utilizing iOS or BlackBerry existing security model, relying on their own implementation of data encryption. ElcomSoft research shows that those implementations fail to provide an adequate level of protection, allowing an attacker to recover encrypted information in less than a day if user-selectable Master Password is 10 to 14 digits long.

The Research

Both platforms being analyzed, BlackBerry and Apple iOS, feature comprehensive data security mechanisms built-in. Exact level of security varies depending on which version of Apple iOS is used or how BlackBerry users treat memory card encryption. However, in general, the level of protection provided by each respective platform is adequate if users follow general precautions.

The same cannot be said about most password management apps ElcomSoft analyzed. Only one password management app for the iOS platform, DataVault Password Manager, stores passwords in secure iOS-encrypted keychain. This level of protection is good enough by itself; however, that app provides little extra protection above iOS default levels. Skipping the complex math (which is available in the original whitepaper), information stored in 10 out of 17 password keepers can be recovered in a day – guaranteed if user-selectable master password is 10 to 14 digits long, depending on application. What about the other seven keepers? Passwords stored in them can be recovered instantly because passwords are either stored unencrypted, are encrypted with a fixed password, or are simply misusing cryptography.

Interestingly, BlackBerry Password Keeper and Wallet 1.0 and 1.2 offer very little protection on top of BlackBerry device password. Once the device password is known, master password(s) for Wallet and/or Password Keeper can be recovered with relative ease.

In the research we used both Elcomsoft Phone Password Breaker and Elcomsoft iOS Forensic Toolkit.

Recommendations

Many password management apps offered on the market do not provide adequate level of security. ElcomSoft strongly encourages users not to rely on their advertised security, but rather use iOS or BlackBerry built-in security features.

In order to keep their data safe, Apple users should set up a passcode and a really complex backup password. The unlocked device should not be plugged to non-trusted computers to prevent creation of pairing. Unencrypted backups should not be created.

BlackBerry users should set up a device password and make sure media card encryption is off or set to “Encrypt using Device Key” or “Encrypt using Device Key and Device Password” in order to prevent attackers from recovering device password based on what’s stored on the media card. Unencrypted device backups should not be created.

ElcomSoft Half-Switches to OpenCL

Thursday, March 8th, 2012

OpenCL_Artwork

ElcomSoft has recently announced the switch to OpenCL, an open cross-platform architecture offering universal, future-proof accessibility to a wide range of acceleration hardware. We’re actively using GPU acceleration for breaking passwords faster. No issues with NVIDIA hardware, but working with AMD devices has always been a trouble.

So we jumped in, embedding OpenCL support into Elcomsoft Phone Password Breaker and Wireless Security Auditor. As an immediate benefit, we were able to add long-awaited support for AMD’s latest generation of graphic accelerators, the AMD Radeon™ HD 7000 Series currently including AMD Radeon™ HD 7750, 7770, 7950, and 7970 models. Headache-free support for future generations of acceleration hardware is icing on the cake.

OpenCL_Benchmark

After switching to OpenCL, we further optimized acceleration code for AMD hardware, squeezing up to 50% more speed out of the same boards. This isn’t something to sniff at, as even a few per cents of performance can save hours when breaking long, complex passwords.

OpenCL vs. CUDA

AMD goes OpenCL. What about NVIDIA? Technically, we could have handled NVIDIA accelerators the same way, via OpenCL (it’s a cross-platform architecture, remember?) In that case, we would be getting a simpler, easier to maintain product line with a single acceleration technology to support.

However, we’re not making a full commitment just yet. While some of us love open-source, publicly maintained cross-platform solutions, these are not always the best thing to do in commercial apps. And for a moment here, we’re not talking about licensing issues. Instead, we’re talking sheer speed. While OpenCL is a great platform, offering future-proof, headache-free support of future acceleration hardware, it’s still an extra abstraction layer sitting between the hardware and our code. It’s great when we’re talking AMD, a company known for a rather inconsistent developer support for its latest hardware; there’s simply no alternative. If we wanted access to their latest state-of-the-art graphic accelerators such as AMD Radeon™ HD 7000 Series boards, it was OpenCL or nothing.

We didn’t have such issues with AMD’s main competitor, NVIDIA. NVIDIA was the first player on this arena, being the first to release graphical accelerators capable of fixed-point calculations. It was also the first to offer non-gaming developers access to sheer computational power of its GPU units by releasing CUDA, an application programming interface enabling developers use its hardware in non-graphical applications. From the very beginning and up to this day, CUDA maintains universal compatibility among the many generations of NVIDIA graphical accelerators. The same simply that can’t be said about AMD.

So is it the “if it ain’t broke, don’t fix it” approach? Partly, but that’s just one side of the coin. CUDA simply offers better performance than OpenCL. The speed benefit is slight, but it is there, and it’s significant enough to get noticed. We want to squeeze every last bit of performance out of our products and computers’ hardware, and that’s the real reason we’ll be staying with CUDA for as long as it’s supported – or until OpenCL offers performance that can match that of CUDA.

Did we make the switch half-heartedly? Nope. We’re enthusiastic about the future of OpenCL, looking forward to run our software on new acceleration platforms. But we don’t want to abandon our heritage code – especially if it performs better than its replacement!

EPPB: Now Recovering BlackBerry Device Passwords

Thursday, September 29th, 2011

Less than a month ago, we updated our Elcomsoft Phone Password Breaker tool with the ability to recover master passwords for BlackBerry Password Keeper and BlackBerry Wallet. I have blogged about that and promised the “next big thing” for BlackBerry forensics to be coming soon. The day arrived.
