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

Attackers Abuse Legitimate Microsoft Defender Exclusions to Conceal Malware
Huntress researchers have detailed an evasion technique in which threat actors avoid disabling Microsoft Defender entirely. Instead, they create targeted exclusions for specific folders or file extensions, allowing malware to operate undetected while the protection status remains apparently active. These exclusions are configured through PowerShell commands, Windows Management Instrumentation, Group Policy, or direct registry modifications, all requiring administrator privileges after initial compromise. A registry key named HideExclusionsFromLocalAdmins can further conceal the list of exclusions from local administrators viewing the interface. The approach has been linked to campaigns involving GootKit in 2019, WhisperGate in 2022 that excluded the entire C: drive, and Muddled Libra in 2024. Defenders are advised to monitor registry changes directly, as this bypasses interface hiding, and to flag exclusions of entire drives or common directories such as temporary and downloads folders.
SC Malware on WordPress Restores Deleted Backdoors in Seconds via Eight Persistence Points
Researchers at Sucuri have analyzed the SC malware targeting WordPress sites, which rapidly restores any removed backdoor components through a minimum of eight interconnected persistence mechanisms. The infection hides across PHP configuration settings, hidden loaders, theme files, and plugins, with some elements executing before standard WordPress plugins load. Copies of the malicious code are also stored in the database and System V shared memory on supported servers, allowing full reinfection from surviving sources after file cleanup. The backdoor evades plugin listings, gathers site and administrator session data, deploys additional PHP code, and disables security plugins while injecting JavaScript for payment data theft in online stores. Command-and-control occurs through public Ethereum RPC gateways and smart contracts with multiple fallback channels. Sucuri warns that PHP caching of the loader directive can crash request handling if the referenced file is deleted without prior preparation, and recommends a sequenced cleanup process.
RATHat Trojan Leverages Google Gemini to Infect and Control Android Devices
The banking trojan RATHat has begun using Google Gemini as an assistant to infect Android smartphones and maintain persistence. Researchers at Cleafy report that the malware first disguises itself as a legitimate application and tricks users into granting Accessibility permissions. Once inside, RATHat activates wireless debugging, connects via ADB, and deploys a separate Go-based service running with system-level privileges. Gemini helps the trojan interpret unfamiliar Android interfaces across different versions, languages, and manufacturer skins by analyzing UI structures and suggesting the correct taps. On the attacker side, the same model processes intercepted SMS messages, evaluates bank balances, and ranks compromised devices by financial value. Since April, Cleafy has observed nearly 100 deployments of the command-and-control infrastructure, pointing to a possible malware-as-a-service model. Removing the original APK is insufficient because the Go service survives independently until reboot and can reinstall the dropped payload.
Mimbrob Malware Uses Fake Dronner App to Target Russian Military and Industrial Firms
Researchers at F6 have identified a new malware campaign dubbed Mimbrob that leverages a fake drone-tracking application called Dronner. The lure promises data on heavy Baba Yaga drones and remote mining locations but instead deploys malicious payloads aimed primarily at Russian military personnel near the front line. The malware checks system language, keyboard layouts, and interface preferences, remaining dormant or terminating if Russian or certain CIS and Romanian languages are absent. Since April 2026 the same operators have conducted phishing campaigns against Russian industrial and IT companies using FBULoader disguised as a Yandex Browser update and the RAT-Go remote access trojan. The attackers register lookalike domains of legitimate Russian enterprises to deliver fake metrology notices and court documents. While espionage appears the most probable objective, researchers have not yet obtained the final payload and therefore refrain from definitive attribution.
