If the computer is normally running macOS or Linux, you may want to boot from a flash drive using Elcomsoft System Recovery. While FIleVault2 and LUKS-encrypted disks that are connected to a Windows computer are rarely encountered in the wild, we have them covered just for those rare cases when you might need them. The tool can detect TrueCrypt/VeraCrypt, BitLocker, PGP WDE, FileVault2, BestCrypt and LUKS. In order to detect the presence of full-disk encryption, we suggest using Elcomsoft Encrypted Disk Hunter.Įlcomsoft Encrypted Disk Hunter is a free portable command-line tool to help experts quickly discover the presence of encrypted volumes when performing live system analysis. If one or more encrypted volumes are detected, or if there a signs that full-disk encryption might have been used on the system, additional steps must be taken to further investigate the live system in order to secure and preserve evidence that could be lost if the computer was powered off. We are suggesting a way for securing access to evidence during incident response by analyzing the live system for signs of full-disk encryption. Not only does it lock experts out of evidence stored on encrypted volumes that have been mounted during the acquisition, but depending on the type of protector used to secure the volume the evidence may become completely inaccessible once the disk is removed from the original computer. The classic workflow had always involved pulling the plug, taking the disks out, write-blocked imaging and subsequent analysis of the image files. Accessing evidence stored on encrypted disk volumes may not be possible without breaking the encryption first. The Challengeįull-disk encryption is an ongoing challenge for forensic experts. In December 2021, we added BestCrypt Volume Encryption 4 и 5 to both Elcomsoft Encrypted Disk Hunter and Elcomsoft Distributed Password Recovery. What steps are required and how to tell if the system is using full-disk encryption? “We have a tool for that”. 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. The wide spread of full-disk encryption makes live system analysis during incident response a challenge, but also an opportunity.
