• File name: /private/var/mobile/home/.tmp
  Description: This is the file where /private/var/mobile/home/syslog stores received raw data from its command and control (C&C) server
• File name: /private/var/mobile/home/sshd
  Description: Trend Micro detects this malicious executable as IOS_IKEE.A. It scans for IP addresses into which it will propagate to. It propagates by logging into the target iPhone via SSH using the default password, "alpine". It creates the folder, /private/var/mobile/home/, where it copies the malware package, CYDIA.TGZ. It then executes /private/var/mobile/home/inst to install the malware package.
• File name: /private/var/mobile/home/duh
  Description: This is the malicious binary file used by this malware to issue HTTP GET commands. This is executed by /private/var/mobile/home/syslog to receive data from its C&C server.
• File name: /private/var/mobile/home/inst
  Description: Trend Micro detects this malicious script as IOS_IKEE.A. It generates an ID for the infected iPhone which can be used as an identifier when this script connects to its C&C server. The generated ID is saved in /etc/rel. It then copies com.apple.ksyslog.plist to /System/Library/LaunchDaemons/com.apple.ksyslog.plist so that this script executes every time the infected device is turned on. In addition, it installs legitimate Debian packages necessary for its routines. It also changes the default SSH password, alpine that is saved in /etc/master.passwd to ohshit. This file is responsible for gathering all SMS messages and information about the infected device. SMS messages are saved in /private/var/mobile/home/{ID}/sms.txt while phone information are saved into /private/var/mobile/home/{ID}/info. It then archives the folder, /private/var/mobile/home/{ID}, and connects to its C&C server, {BLOCKED}.{BLOCKED}.38.16/xml/a.php?name={ID} to send the .TGZ file in base64 format.
• File name: /private/var/mobile/home/heh
  Description: This file is where /private/var/mobile/home/syslog saves shell scripts to be executed.
• File name: /private/var/mobile/home/syslog
  Description: Trend Micro detects this malicious script as IOS_IKEE.A. This file runs /private/var/mobile/home/duh and saves the C&C server replies to /private/var/mobile/home/.tmp. It parses the .TMP file for scripts then saves the result in /private/var/mobile/home/heh and executes this file as a shell script.
