Malware

XLoader for iOS

XLoader for iOS is an iOS malware family associated with mobile device profiling and data theft. Documented behavior includes collecting device-identifying information such as UDID, version and product information, and subscriber or hardware identifiers including IMEM, ICCID, and MEID. The malware has also been observed exfiltrating stolen data over HTTP, indicating use of standard application-layer network traffic for outbound theft and likely command-and-control blending. The available reporting supports XLoader for iOS as a mobile surveillance or information-stealing threat focused on harvesting host metadata from compromised iOS devices. High-confidence public details in the available material are limited, and no specific initial infection vector, industry targeting, or threat-actor attribution is established here.
