Accessing a locked system is always a challenge. Encrypted disks and encrypted virtual machines, encrypted files and passwords are just a few things to mention. In this article we are proposing a straightforward workflow for investigating computers in the field.

Criminals are among the most advanced users of modern technology. They learned how to hide information in their smartphones and how to encrypt their laptops. They communicate via secure channels. Their passwords never leak, and they do their best to leave no traces. Forensic investigators encounter new challenges every other day. In this article, we will discuss yet another tool used by the criminals to cover their traces: the encrypted virtual machine.

Making tools for breaking passwords, I am frequently asked whether it’s legal, or how it works, or what one can do to protect their password from being cracked. There are people who have “nothing to hide”. There are those wearing tin foil hats, but there are a lot more people who can make a reasonable effort to secure their lives without going overboard. This article is for them.

Everyone’s iPhones contain overwhelming amounts of highly sensitive personal information. Even if some of that data is not stored on the device, the iPhone itself or the data inside can work as a key to other many things from bank accounts to private family life. While there are many possible vectors of attack, the attacker will always try exploiting the weakest link. Learn to think like one, find the weakest link and eliminate the potential vulnerabilities before they are exploited. This guide comes from the forensic guys making tools for the law enforcement, helping the good guys break into the bad guys’ iPhones.

Breaking LUKS Encryption

August 18th, 2020 by Oleg Afonin

LUKS encryption is widely used in various Linux distributions to protect disks and create encrypted containers. Being a platform-independent, open-source specification, LUKS can be viewed as an exemplary implementation of disk encryption. Offering the choice of multiple encryption algorithms, several modes of encryption and several hash functions to choose from, LUKS is one of the tougher disk encryption systems to break. Learn how to deal with LUKS encryption in Windows and how to break in with distributed password attacks.

The wide spread of full-disk encryption makes live system analysis during incident response a challenge, but also an opportunity. A timely detection of full-disk encryption or a mounted crypto container allows experts take extra steps to secure access to encrypted evidence before pulling the plug. What steps are required and how to tell if the system is using full-disk encryption? “We have a tool for that”.

Breaking passwords becomes more difficult with every other update of popular software. Microsoft routinely bumps the number of hash iterations to make Office document protection coherent with current hardware. Apple uses excessive protection of iTunes backups since iOS 10.1, making brute force attacks a thing of the past. VeraCrypt and BitLocker were secure from the get go. However, everything is not lost if you consider human nature.

There is a bit of confusion about our software designed to allow breaking into password-protected systems, files, documents, and encrypted containers. We have as many as three products (and five different tools) dealing with the matter: Elcomsoft Forensic Disk Decryptor (with an unnamed memory dumping tool), Elcomsoft System Recovery and Elcomsoft Distributed Password Recovery, which also includes Elcomsoft Hash Extractor as part of the package. Let’s briefly go through all of them. Hopefully it will help you select the right product for your needs and save time in your investigation.

VeraCrypt is a de-facto successor to TrueCrypt, one of the most popular cryptographic tools for full-disk encryption of internal and external storage devices. Compared to TrueCrypt, which it effectively replaced, VeraCrypt employs a newer and more secure format for encrypted containers, and significantly expands the number of supported encryption algorithms and hash functions. Learn how to break VeraCrypt containers with distributed password attacks.

Just days ago, we have reviewed the data stored in iCloud, and studied its encryption mechanisms. We also discussed the discrepancies between the data that is stored in the cloud and the data that’s provided to the law enforcement. In case you missed it, make sure to check out Apple vs. Law Enforcement: Cloud Forensics. Today, the differences are great; Apple is using point-to-point encryption to protect certain types of data. However, it has not always been that way. Apple security model changed year after year. This article reviews the timeline of Apple security changes over time.
