Overview
This Bundle features Amazon Linux 2 along with the well-known John the Ripper jumbo password cracker pre-built and pre-configured with multi-GPU (via OpenCL) and multi-CPU support (with AVX-512, AVX2, and AVX acceleration, and transparent fallback when run on older CPUs lacking the latest AVX extensions). The build is supported and has been tested on AWS GPU (NVIDIA only) and CPU instances (Intel and AMD).
John the Ripper jumbo supports recovering or auditing security of passwords to hundreds of different hash and cipher types, including all sorts of Unix flavors' (Linux, *BSD, Solaris, AIX, QNX, etc.), macOS, Windows, "web apps", and groupware (e.g., Notes/Domino) user password hashes, various SQL and LDAP server password hashes, as well as many "non-hashes" such as SSH private keys, Kerberos TGTs, network traffic captures (Windows network authentication, WiFi WPA-PSK, etc.), encrypted filesystems such as macOS .dmg files and "sparse bundles" and Microsoft Bitlocker, encrypted archives such as ZIP (classic PKZIP and WinZip/AES), RAR, and 7z, encrypted document files such as PDF and Microsoft Office's. These are just some of the examples - there are many more. To load the "non-hashes", a corresponding *2john conversion program should be used first - these are also part of this Bundle.
Also included are wordlists (20+ languages) from the Openwall wordlists collection, sample Unix and Windows password hashes, and sample encrypted files for testing and learning how to use the software.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.

Additional details
Usage instructions
SSH in as "ec2-user". There's prebuilt and preconfigured John the Ripper in the home directory. To run it, simply type "john". You can similarly invoke the helper programs such as "zip2john". All of these reside in "john/run". Documentation is under "john/doc".
This build of John the Ripper includes both GPU and CPU support. To use GPUs, use the "-opencl" formats. To use multiple GPUs, use the "--fork" option (e.g. "--fork=2" to use 2 of them).
You may also concurrently use CPUs (formats without "-opencl" in their names) by specifying a different "--session" name and a non-overlapping attack.
When you don't request a particular attack, the default wordlist (1.8 million common passwords) with default optimized mangling rules (3000+ of them) will be used, followed by an effectively never-ending "incremental mode" attack that starts with more probable candidate passwords (per trigram frequencies seen in a training set) and slowly proceeds towards less probable ones.
Upon reboot (such as if a persistent spot instance is stopped and restarted), "screen -d -m john --restore" is run via cron, which resumes the default session. To attach to the session, use "screen -r". This is meant to be helpful, but in case it is undesired remove the cron job or specify a session name via the "--session" option.
To list the NVIDIA GPUs and see their current utilization, run "nvidia-smi".
