KeyRaider Malware Has Stolen Over 225,000 Apple Accounts From Jailbroken iOS Devices

Posted August 31, 2015 at 10:03pm by iClarified
Palo Alto Networks has identified a new iOS malware family dubbed 'KeyRaider' which has stolen over 225,000 valid Apple accounts with passwords from jailbroken devices. With help from WeipTech, the company found 92 samples of malware responsible for may be the largest theft of Apple accounts caused by malware.

KeyRaider is distributed through third-party Cydia repositories, primarily in China. It hooks system processes through MobileSubstrate and steals Apple account usernames, passwords and device GUIDs by intercepting iTunes traffic. It also steals Apple push notification service certificates and private keys, steals and shares App Store purchasing information, and disables local and remote unlocking functionalities on iPhones and iPads.

The stolen data is uploaded to a command and control server and used by two jailbreak tweaks (iappstore and iappinbuy) to facilitate free App Store purchases.

These two tweaks will hijack app purchase requests, download stolen accounts or purchase receipts from the C2 server, then emulate the iTunes protocol to log in to Apple’s server and purchase apps or other items requested by users. The tweaks have been downloaded over 20,000 times, which suggests around 20,000 users are abusing the 225,000 stolen credentials.

Due to a vulnerability in the command and control server, researchers were able to download about half the accounts before their presence was detected and blocked. To check if your account is on the partial list of compromised accounts, click here.

A better method to check if your device is compromised involves searching for strings on your device:

1. Install openssh server through Cydia
2. Connect to the device through SSH
3. Go to /Library/MobileSubstrate/DynamicLibraries/, and grep for these strings to all files under this directory:
● wushidou
● gotoip4
● bamu
● getHanzi

If any dylib file contains any one of these strings, Palo Alto Networks urges users to delete it and delete the plist file with the same filename, then reboot the device. It's also recommended that all affected users change their Apple account password after removing the malware, and enable two-factor verifications for their Apple IDs.

To make matters worse, KeyRaider has the ability to hold your device and account at ransom.

Some previous iPhone ransomware attacks are based on remotely controlling the iOS device through the iCloud service. Some of these attacks can be avoided by resetting the account password to regain control of iCloud. KeyRaider is different. It can locally disable any kind of unlocking operations, whether the correct passcode or password has been entered. Also, it can send a notification message demanding a ransom directly using the stolen certificate and private key, without going through Apple’s push server. Because of this functionality, some of previously used “rescue” methods are no longer effective.

More details on how the malware works can be found at the link below. As usual we recommend you only install tweaks from trusted sources or default repositories.

@Alpina dont you get that this shiit steals your info so far you are jailbroken? !!!!!
stevenlacross - September 2, 2015 at 3:02pm
Actually your wrong. It only steals your info if you installed those two tweaks after you jailbroke your phone. Those two tweaks are for getting apps for free. so those of us who aren't trying to steal apps, haven't gotten our Apple ID stolen, LEARN how to read before you post a stupid comment.

never says the malware comes from those two tweaks. only that the two tweaks are using the stolen info. it doesn't seem like they're figured out yet exactly which tweaks are loading the malware into the phone

Im Jailbroken. But not effected. I allways get my Apps from App Store.

No bashing hiding behind a computer, just stick to the issue at hand. Both Android and IOS has security flaws. You can jailbreak or root because of security flaws. No software is secure so you have to live with it. Please be civilized and only say what you will say in front of a crowd of people, not hiding behind a computer.

Those who say that people who jailbreak do it to steal apps, clearly missed the mark. While it is possible to do, the vast majority of the jailbreak community do it make their iPhone experience better. Tweak lockscreen, add functionality, and overall make their phone more personal. Yes it sucks that because jailbroken phones have the ssh ability they are vulnerable, but you can tweak your phone to only allow ssh when you want to use it. So those of you saying all jailbreakers are pirates and getting what they deserve need to research what jail breaking is before you hate it. You sound ignorant.

This is simply not true. Saurik and Musclenerd have both acknowledged that traffic data from jailbroken phones tells us that the VAST MAJORITY of jailbreakers do it to pirate apps.

HAHA I have been saying this for years you really do not know what lurking or who's looking into your jailbroken iDevices...

Good! y'all jailbroken dudes are giving Apple a bad name.

Yo Ho Ho! Pirates never learn.

My device is jailbroken and i do pay for all my apps.

@iClarified team: for the second method recommended in the post, it would be useful, I think to add step-by-step instructions how to grep for those strings, for the average users who might know about openssh and use of the terminal but might master the use of terminal commands like grep...

I feel sorry for those who have had their accounts hacked, but you got them hacked by trying to get shit for free, so you kinda deserve it.
