☎️ A live phone call. A remote access trojan. An NFC relay malware.

Group-IB researchers uncovered WindRelay, a previously unseen Android NFC relay malware deployed alongside SpyNote RAT in a live-call fraud scheme.

The investigation reveals how threat actors are combining:
🔹 Social engineering calls with personalized RAT delivery
🔹 Remote sideloading of NFC relay malware
🔹 Real-time interception and relay of EMV card transactions
🔹 23 related samples and four C2 IPs linked to WindRelay activity

The findings also highlight why defenders should look beyond screen-sharing detection and monitor Accessibility Service abuse, sideloaded apps, suspicious permissions, and NFC activity.

🚨 Group-IB uncovers Vwork, a weaponized fork of the open-source Android app cloner Shelter, used alongside the Gigabud banking trojan.

Vwork abuses Android Work Profiles to clone banking apps into an isolated environment, helping attackers evade detection and bypass fraud controls.

Vwork-compatible Gigabud samples were identified across LATAM, MENA, and APAC, targeting Brazil, Colombia, Egypt, Indonesia, Laos, Mexico, Morocco, the Philippines, Thailand, Türkiye, and a GCC member state.

In Indonesia, Group-IB observed 1,469 compromised devices and 1,281 potentially compromised logins between February and July 2026, with estimated losses of $960,939.

🚨Group-IB researchers have uncovered RemControl, a previously undocumented Android banking trojan operating as Malware-as-a-Service (MaaS). First observed in July 2026, RemControl abuses Android’s Accessibility Service to inject phishing overlays over legitimate banking applications, capture sensitive credentials, stream the victim’s screen, log interactions, and remotely control the device.

The threat goes beyond credential theft. Its infrastructure includes an exposed operator panel for managing bots, overlay templates, stolen credentials, remote sessions, and affiliate-specific APK builds. The malware also uses a local VPN to interfere with Google Play Protect during installation and retrieves its command-and-control address through an encrypted Telegram dead-drop mechanism.

Researchers also identified evidence of AI-assisted development, including an AI-generated response accidentally left inside a live phishing page.
