Spyware-Laden Modified iOS Apps Distributed via Russian Telegram Channel, Kaspersky Discovers

Kaspersky researchers have identified modified versions of popular iOS applications that are being distributed through a Russian-language Telegram channel and contain a malicious spying module. The infected apps include a marketplace platform for selling goods, a photo editor, and a video viewing service, all offered as ad-free versions with extra free features. Attackers embed the spyware directly into legitimate IPA files, while some clean apps simply promote the same channel to funnel users toward the malicious downloads. Installation requires users to obtain a developer certificate and sign the app using tools such as eSign or Scarlet, or to sideload via a computer or jailbroken device, completely bypassing the App Store. Once launched, the malware collects device name, battery level, regional settings, memory information, jailbreak status, geolocation, carrier code, and screenshots before sending the data to the attackers, although it stops when the app is closed. Kaspersky advises users to obtain applications only from official stores or verified developer websites rather than random Telegram sources.

Kaspersky researchers have uncovered a scheme distributing modified iOS applications containing spyware through a Russian-language Telegram channel.

The collection includes altered versions of an online marketplace for selling goods, a photo editor, and a video viewing service. These apps are presented as ad-free and feature-rich, making them attractive to users seeking free enhancements.

Attackers insert a malicious module into otherwise legitimate applications. Some unmodified apps in the channel simply advertise the same Telegram source, directing users toward the infected files.

Installation requires sideloading: users must download an IPA file, purchase a developer certificate, and sign the application using tools such as eSign or Scarlet. The process can also be performed from a computer or on a jailbroken device, avoiding the App Store entirely.

While the app remains open, the spyware gathers the device name, battery level, regional settings, memory details, and jailbreak status. It can also obtain geolocation data, the mobile operator code, and capture screenshots before transmitting everything to the attackers.

The malware does not function in the background, so surveillance stops when the application is closed. Nevertheless, a single captured screenshot can still provide significant value to the operators.

Kaspersky recommends installing applications exclusively from trusted sources such as the official App Store or verified developer websites to avoid such risks.
