eSurv is mobile surveillance malware documented with both Android and iOS functionality. It is associated with data theft from compromised devices, including exfiltration of contact lists and device pictures, and its iOS variant is capable of collecting device information for host profiling. Reported exfiltration activity uses standard application-layer network traffic, specifically HTTP PUT requests, which can help the malware blend with normal mobile communications. The observed behavior is consistent with spyware or surveillance-oriented malware focused on harvesting user data from mobile devices rather than destructive effects.
