WireLurker is a sophisticated family of malware that targets both macOS and iOS systems. Initially discovered by Palo Alto Networks, this malware is notable for its ability to infect iOS devices through a USB connection to an infected macOS computer. It represents a significant evolution in malware due to its cross-platform capabilities and its ability to affect both jailbroken and non-jailbroken devices.
Designed primarily to target users in China, WireLurker was distributed through the Maiyadi App Store, where it trojanized hundreds of OS X applications. This malware family is particularly concerning because it automates the generation of malicious iOS applications and employs advanced techniques like file hiding, code obfuscation, and encryption to evade detection. WireLurker's discovery marked a new era in the landscape of Apple device security threats.
How does WireLurker Work?
WireLurker operates by monitoring any iOS device connected via USB to an infected macOS computer. Once a connection is detected, it installs malicious applications onto the iOS device. These applications can be either downloaded third-party apps or automatically generated by WireLurker. The malware is capable of infecting both jailbroken and non-jailbroken devices, making it particularly versatile.
To avoid detection, WireLurker employs several advanced techniques. It uses file hiding, code obfuscation, and customized encryption to mask its presence and activities. Additionally, the malware regularly communicates with command and control servers to receive updates, ensuring it remains effective and up-to-date. This combination of stealth and adaptability makes WireLurker a formidable threat in the cybersecurity landscape.
What are Examples of WireLurker Attacks?
One notable example of WireLurker attacks involved the trojanization of 467 OS X applications on the Maiyadi App Store, a third-party Mac application store in China. These infected applications were downloaded over 356,104 times, potentially impacting hundreds of thousands of users. The malware was designed to monitor iOS devices connected via USB to an infected macOS computer, allowing it to install malicious applications on both jailbroken and non-jailbroken devices.
Another significant instance was the discovery of a Windows variant of WireLurker. This variant was distributed by a different Chinese source, hosting 180 Windows executables and 67 Mac OS X applications, each containing a version of the WireLurker Trojan. These samples were uploaded to Baidu YunPan and downloaded 65,213 times. The malware attempted to infect jailbroken iOS devices with a malicious iOS binary file that stole user contacts and other private data, which was then sent to a command and control server.
What are the Potential Risks of WireLurker?
Data Theft: WireLurker can steal sensitive information from infected devices, including contacts and other private data, which can be exploited for malicious purposes.
Unauthorized Access: The malware installs malicious applications without user consent, leading to unauthorized access to personal and potentially sensitive information.
Device Compromise: WireLurker's ability to infect both jailbroken and non-jailbroken devices can compromise the normal functionality of the device, making it unreliable and unsafe to use.
Privacy Invasion: By stealing contacts and other private data, WireLurker invades user privacy and can lead to further exploitation of personal information.
Business Disruption: The widespread infection of devices can disrupt business operations, leading to data breaches, operational downtime, and the diversion of resources to address the threat.
How can you Protect Against WireLurker?
Install Software from Trusted Sources: Only download applications from the Mac App Store or identified developers to minimize the risk of malware.
Keep Your Software Updated: Regularly update both your macOS and iOS software to ensure you have the latest security patches.
Use Security Software: Employ antivirus or security protection for macOS and keep the antivirus signatures up-to-date.
Avoid Untrusted Connections: Do not connect your iOS device to unknown computers or use untrusted chargers and accessories.
Set Security Preferences: Configure your Mac's System Preferences to allow apps downloaded only from the Mac App Store and identified developers.
Rapidly implement a modern Zero Trust network that is more secure and maintainable than VPNs.
