In today’s digital age, the line between legitimate software and malicious tools has blurred, creating a complex landscape of cybersecurity threats. One particularly insidious example is FinSpy (also known as FinFisher), a sophisticated spyware developed and marketed by a reputable IT firm. Unlike traditional malware crafted by underground hackers, FinSpy poses a legitimate yet serious threat to privacy and security, and over the last year, traces of this software have been discovered on numerous mobile devices.
What FinSpy Gets Up To
Though it has versions for desktop operating systems like Windows, macOS, and Linux, the mobile variants of FinSpy are particularly alarming. This spyware can be deployed on both iOS and Android devices, offering an identical suite of functionalities regardless of the platform. Once installed, FinSpy grants the attacker nearly unfettered control over the infected device, allowing for extensive data collection.
FinSpy is versatile in its configuration. Attackers can tailor it uniquely for each victim, enabling them to gather detailed information about the user. This includes access to contacts, call history, real-time geolocation, texts, and calendar entries, among other private data.
Additionally, the spyware’s capabilities extend beyond mere data collection. FinSpy can record voice and VoIP calls, intercept instant messages across numerous communication services, such as WhatsApp, WeChat, Viber, Skype, Line, Telegram, and even more secure options like Signal and Threema. It extracts not only messages but also files exchanged through these platforms, along with information about group chats and contacts.

Who Should Beware of FinSpy
Infections from FinSpy typically spread through methods similar to those of other types of malware. Users often unknowingly click malicious links embedded in emails or text messages, which can lead to infection.
Android users are particularly vulnerable, especially if their devices are rooted, making it significantly easier for malware to operate. Even for unrooted devices, if a rooting app is present, FinSpy can exploit that to gain root access. Moreover, vulnerabilities like the DirtyCow exploit can be used to breach devices lacking root access altogether.
Apple users are somewhat insulated from this threat, thanks to the stricter security protocols inherent in iOS. However, if a device has been jailbroken, it can be infected in a manner similar to Android devices. For non-jailbroken devices, the attacker would need physical access to the phone to jailbreak it manually before deploying FinSpy.
How to Guard Against FinSpy
To protect yourself from falling victim to FinSpy and similar spyware, it’s crucial to follow established cybersecurity guidelines:
- Avoid clicking on suspicious links received through emails, instant messages, or texts.
- Refrain from attempting to root (for Android) or jailbreak (for iOS) devices that store sensitive information.
- Utilize a reputable security solution capable of detecting threats like FinSpy, keeping in mind that effective options for iOS are limited (here’s why).
