Update, 17 August 2018.

Although this project is technically dead, in light of certain events, I have patched and returned InflatableDonkey to a functional state.

Please don't take this an indication that this project is being resurrected, it is not. I apologise for this.

Once again, I would like to clarify that InflatableDonkey is only to be used to access backups that you own.

What is it?

Java proof of concept iOS9+ iCloud backup retrieval tool. Educational/ personal backup usage only.


Requires Java 8 JRE/ JDK and Maven.

Download, extract and navigate to the InflatableDonkey-master folder:

~/InflatableDonkey-master $ mvn package

The executable Jar is located at /target/InflatableDonkey.jar


~/InflatableDonkey-master/target $ java -jar InflatableDonkey.jar --help

Dates are ISO format e.g. 2000-12-31. Filters are case insensitive.
Pass multiple argument values separated by spaces e.g. --extension png jpg

AppleId/ password.

~/InflatableDonkey-master/target $ java -jar InflatableDonkey.jar uhhurhur

DsPrsID/mmeAuthToken. Preferable for consecutive runs as repeated appleId/ password authentication over short periods may trip anti-flooding/ security controls.

~/InflatableDonkey-master/target $ java -jar InflatableDonkey.jar 1234567890:AQAAAABWJVgBHQvCSr4qPXsjQN9M9dQw9K7w/sB=

Print DsPrsID/mmeAuthToken and exit.

~/InflatableDonkey-master/target $ java -jar InflatableDonkey.jar uhhurhur --token

With HTTPS proxy.

~/InflatableDonkey-master/target $ java -Dhttps.proxyHost=HOST -Dhttps.proxyPort=PORT -jar InflatableDonkey.jar uhhurhur --token

List devices/ snapshots.

~/InflatableDonkey-master/target $ java -jar InflatableDonkey.jar uhhurhur --snapshots

By default the user is presented with a device/ snapshot selection screen. You can also pass in device/ snapshot details manually. Devices are referenced by their UUIDs or part of, snapshots by their indices.

~/InflatableDonkey-master/target $ java -jar InflatableDonkey.jar uhhurhur --device B648BD20296F0C6D20DFB2F0A52C8314AF5FCEC7 --snapshot 0

There are a number of filters available. To download thumbs from WhatsApp:

~/InflatableDonkey-master/target $ java -jar InflatableDonkey.jar uhhurhur --domain whatsapp --extension thumb

Download a selection of photos (those ending in 0.jpg and 5.jpg) from the CameraRollDomain

~/InflatableDonkey-master/target $ java -jar InflatableDonkey.jar uhhurhur --domain camera --extension 0.jpg 5.jpg

List domains and the file count for each domain, then exit.

~/InflatableDonkey-master/target $ java -jar InflatableDonkey.jar uhhurhur --domains

Download all files from the HomeDomain.

~/InflatableDonkey-master/target $ java -jar InflatableDonkey.jar uhhurhur --domain homedomain

The are two data protection decryption modes but the detection algorithm is only about 90% accurate. If you experience file corruption please try setting the mode manually with either --mode CBC or --mode XTS.

For example CBC mode.

~/InflatableDonkey-master/target $ java -jar InflatableDonkey.jar uhhurhur --mode CBC

For further information please refer to the comments/ code in Main. Running the tool will detail the client/ server responses for each step, including headers/ protobufs. You can play with logback.xml and adjust the Apache HttpClient header/ wire logging levels.

There have been some contributors who, rather like vampires, prefer the cover of darkness. You know who you are and thank you!

I've also probably forgotten others. If so I'm sorry and thank you too!

You can’t perform that action at this time.
