Kaspersky experts have uncovered new versions of the advanced malicious surveillance tool FinSpy. The new implants work on both iOS and Android devices, can monitor activity on almost all popular messaging services, including encrypted ones, and hide their traces better than before. The tools allow attackers to spy on all device activities and exfiltrate sensitive data such as GPS location, messages, pictures, calls and more.
FinSpy is an extremely effective software tool for targeted surveillance that has been observed stealing information from international NGOs, governments and law enforcement organizations all over the world. Its operators can tailor the behaviour of each malicious FinSpy implant to a specific target or group of targets.
The basic functionality of the malware includes almost unlimited monitoring of the device’s activities: such as geolocation, all incoming and outgoing messages, contacts, media stored on the device, and data from popular messaging services like WhatsApp, Facebook Messenger or Viber. All the exfiltrated data is transferred to the attacker via SMS messages or the HTTP protocol.
The latest known versions of the malware extend the surveillance functionality to additional messaging services, including those considered ‘secure’, such as Telegram, Signal or Threema. They are also more adept at covering their tracks. For instance, the iOS malware, targeting iOS 11 and older versions can now hide signs of jailbreak, while the new version for Android contains an exploit capable of gaining root privileges – almost unlimited, complete access to all files and commands - on an unrooted device.
Based on the information available to Kaspersky, in order to successfully infect both Android and iOS-based devices, attackers need either physical access to the phone or an already jail broken/rooted device. For jail broken/rooted phones there are at least three possible infection vectors: SMS message, email, or push notifications.
According to Kaspersky telemetry, several dozen mobile devices have been infected over the past year. To avoid falling victim to FinSpy, Kaspersky researchers advice users to not leave your smartphone or tablet unlocked and always make sure nobody is able to see your pin-code when you enter it, not to jailbreak or root your device since it will make an attacker’s job easier, only install mobile applications from official app stores, such as Google Play, do not follow suspicious links sent to you from unknown numbers, and also in your device settings block the installation of programs from unknown sources and avoid disclosing the password or passcode to your mobile device, even with someone you trust. Never store unfamiliar files or applications on your device, as they could harm your privacy and download a proven security solution for mobile devices, such as Kaspersky Internet Security for Android....
