In August 2026, a Casbaneiro campaign targeted Latin American users through phishing emails and PDFs themed as fake invoices and legal notices. The multi-stage infection chain includes HTA downloaders and AutoIt loaders, employing geofencing to filter victims by IP address location. The malware exhibits sophisticated evasion techniques, including distributed data-receiving servers, deliberate HTTP 403 responses, and activation only when victims access targeted banking websites. Casbaneiro steals email data, performs clipboard injection, and creates fake windows for fraudulent activities. The campaign specifically targets Argentina, Peru, Colombia, and Mexico while avoiding German, French, and English language systems. The malware splits stolen data across multiple servers and uses malformed HTTP packets to complicate detection and analysis efforts.

ThreatFabric researchers discovered StreamRat, a sophisticated Android banking trojan distributed through Meta and TikTok advertisements disguised as a free TV-streaming service targeting Spanish-speaking users. The campaign reached approximately 570,000 potential victims, primarily in Spain. StreamRat employs a two-stage installation process, utilizing a dropper that implements internet-blocking mechanisms via non-functional VPN connections. Once installed, the trojan abuses Accessibility Services and MediaProjection API to provide operators with near-complete device control, featuring VNC and hidden-screen control, UI-tree collection, keylogging, credential-stealing overlays, and screen-blocking capabilities. The malware appears designed as a Malware-as-a-Service offering, with a sophisticated control panel supporting multiple user roles and WebSocket-based C2 communications.

A newly identified Android malware family named Manic combines banking malware and mobile spyware capabilities, targeting Ukrainian banks, government services, messaging applications, Russian and European financial institutions, and global fintech and cryptocurrency services. Active since February 2026, Manic enables extensive Device Takeover operations through sophisticated surveillance and remote-control features. It employs advanced PIN stealing techniques without requiring traditional overlay attacks, utilizing Accessibility services as a UI keylogger to capture lock-screen inputs, recovery phrases, and authentication codes. A distinctive feature is its Wi-Fi mesh egress technique, allowing compromised devices to relay stolen data through other infected phones via Wi-Fi Direct, Bluetooth, or BLE when direct C2 access is unavailable. The malware monitors 169 applications including banks, cryptocurrency wallets, government eID services, and military-focused messengers across multiple countries.

Grandoreiro, a notorious banking trojan active since 2016 across Latin America, continues operations despite major law enforcement disruption in 2024. Recent campaigns leverage DLL sideloading techniques, abusing the legitimate Duplicate Files Finder application to execute malicious code. The loader incorporates extensive anti-analysis mechanisms including sandbox detection, virtual machine artifact checks, process blacklisting, and environment profiling to evade automated analysis systems. These defensive checks occur before C2 contact, indicating high priority on avoiding detection. Telemetry from June 2026 shows activity concentrated in Latin America, primarily Mexico, with limited presence in Europe and North America. The malware uses custom string obfuscation combining proprietary decryption with Base64 encoding, and communicates with C2 infrastructure over TCP port 6432 using encrypted requests containing host-specific information.

In June 2026, a previously undocumented Android fraud bot called Octagon was identified, sold as malware-as-a-service by Russian-speaking actor AndroidKitKat for $1,400 monthly. The malware employs accessibility overlays, hidden VNC, SMS interception, unlock-pattern capture, and balance reading capabilities to target cryptocurrency wallets, exchanges, and banking applications. Distributed through sideloaded APKs with Restricted Settings bypass, Octagon connects infected devices to a Windows command-and-control panel where operators monitor applications, read screens, and control devices remotely. The malware maintains persistence through multiple mechanisms while appearing benign to security scans. Three APK samples were recovered, including deployments using Lifted Dreams game and Bahrain government lures. The malware captures credentials through HTML WebView overlays targeting Trust Wallet, Binance, MEXC, MetaMask, and messaging apps like Telegram and WhatsApp, enabling cryptocurrency theft and account t...

An active Lampion malware campaign has been identified targeting Portuguese users through phishing emails that impersonate financial and administrative communications. Lampion, a Brazilian banking malware derived from the ChePro lineage, delivers initial payloads via ZIP archives containing heavily obfuscated HTML files designed to evade detection. The HTML stage retrieves additional scripts from attacker-controlled infrastructure, initiating a multistage VBS infection chain. Each stage employs extensive obfuscation techniques including junk code, encrypted strings, and dynamically generated scripts that inflate file sizes while concealing core functionality. The infection chain is deliberately fragmented across multiple independent execution stages, complicating behavioral analysis. Telemetry shows 94.6% of detections concentrated in Portugal, confirming this is a highly targeted threat focused on Portuguese-speaking victims.

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.

In May 2026, an attack campaign targeting banking users in Spain and Portugal was identified involving the Ousaban banking Trojan. The malware, previously active in Brazil, spreads through phishing PDFs that redirect victims to malicious webpages performing environment checks to ensure targets are located in Spain or Portugal. The attack chain involves VBS scripts downloading steganographic images containing the payload, which is then dropped and executed on victims' systems. Ousaban establishes persistence, monitors banking activity across multiple financial institutions, and uses daily-changing DDNS domains to resolve C2 server addresses. The malware employs screenshot capture, keylogging, clipboard injection, and remote control capabilities to steal banking credentials. It utilizes custom encryption algorithms and geofencing techniques to evade detection and limit exposure to intended targets.
