Threats Tagged 'sms interception'

A malicious campaign was detected impersonating an Italian banking brand through a fraudulent domain offering fake financial rewards for installing a mobile application. Users are redirected to a Telegram bot that distributes a malicious Android APK outside official app stores. The APK functions as a dropper containing an embedded second-stage payload identified as Albiriox, an Android banking Remote Access Trojan. This payload exploits Accessibility services, implements overlay attacks, intercepts SMS messages, captures credentials, and enables remote device control through a custom TCP-based command-and-control protocol. The infrastructure uses domain impersonation and social engineering with financial incentives to distribute the malware. Communication occurs via raw TCP sockets to endpoints on ports 5555 and 5552, with JSON messages framed using big-endian length prefixes. Attribution to Albiriox is supported by protocol similarities, behavioral patterns, and comparison with known Albiriox samples.

An Android malware campaign masquerading as a bank KYC verification application targets users in India through WhatsApp distribution. The threat operates as a multi-stage dropper installing secondary payloads while establishing persistent command-and-control communication. It combines native code obfuscation, Firebase-based remote execution, VPN-based traffic manipulation, and WebView-based phishing to systematically harvest sensitive user data. The infection chain progresses through deceptive update screens, VPN activation, silent APK installation, and extensive permission abuse. The deployed payload enables SMS interception, call control, USSD execution, and structured credential theft through staged phishing interfaces mimicking legitimate banking workflows. Exfiltrated data is encrypted locally and transmitted to jsonapi.biz, while critical configuration values are hidden inside native libraries to hinder detection.

GhostGrab is a sophisticated Android malware that combines cryptocurrency mining with extensive data theft, targeting sensitive financial information such as banking credentials, debit card details, and OTPs. It exploits device resources for mining while maintaining persistence through advanced hiding techniques and resisting removal. The malware abuses permissions to access SMS, calls, and storage, enabling comprehensive data exfiltration. It uses Firebase for command-and-control and data exfiltration, masking malicious activity within legitimate cloud traffic. Its modular design includes WebView-based phishing pages aimed at financial fraud and identity theft. The malware infrastructure involves recently registered domains and obfuscation services, indicating a professional operation. GhostGrab exemplifies the convergence of financial cybercrime and resource exploitation in mobile malware, posing a significant threat to Android users. European organizations with mobile banking users are at risk, especially where Android market share is high. Mitigation requires enhanced mobile security controls, user awareness, and network monitoring for suspicious Firebase traffic.

Kaspersky researchers have discovered a new version of the Triada Trojan being distributed through infected Android device firmware. The malware is embedded into system files before devices are sold, making it nearly impossible to remove. It infects the Zygote process to compromise all apps on the device. The Trojan's modular architecture allows attackers to deliver targeted payloads for stealing cryptocurrency, credentials, and other sensitive data from popular apps like WhatsApp, Facebook, and banking apps. It can also intercept SMS messages, make calls, and act as a reverse proxy. Over 4,500 infected devices have been detected worldwide, with the highest numbers in Russia, UK, Netherlands, Germany and Brazil. The attackers have stolen over $264,000 in cryptocurrency so far.
