New STX RAT Uses Hidden Remote Desktop and Infostealer Features to Evade Detection

A newly identified remote access trojan, STX RAT, emerged in 2026, integrating hidden remote desktop access with credential theft features. The name "STX" comes from the Start of Text magic byte x02, which it appends to communications with its command-and-control (C2) server. Initial sightings were reported in late February 2026, when it was delivered via a browser-downloaded VBScript file to a financial organization. By early March, Malwarebytes noted a campaign distributing STX RAT through compromised FileZilla installers. Researchers from eSentire’s Threat Response Unit analyzed the malware, which includes extensive anti-analysis measures and employs techniques like AMSI-ghosting. Once operational, STX RAT connects to a C2 server at 95.216.51.236, transmitting system information securely. It targets saved credentials from applications like FileZilla and includes a Hidden Virtual Network Computing (HVNC) module, allowing attackers to control a victim's machine without detection. Security teams are advised to block the C2 IP and implement detection rules to mitigate the threat.

Trojanized Android App Fuels New Wave of NFC Fraud

A new variant of the NGate malware family has emerged, using a trojanized Android application to capture payment card data and personal identification numbers (PINs). This modified version of HandyPay, a legitimate NFC relay app, has been distributed since November 2025, primarily targeting users in Brazil. The malware intercepts NFC payment card data and allows fraudulent transactions. Two distinct malware samples have been observed, delivered through phishing infrastructure that impersonates a Brazilian lottery site and a Google Play listing for a card protection tool. The trojanized app captures NFC data, requests the victim's card PIN, and transmits this information to attacker-controlled infrastructure. It requires minimal permissions, leveraging its role as the default payment application to evade detection. Evidence suggests that generative AI tools may have been used in its development, indicated by emoji markers in debug logs. ESET has reported its findings to Google, and Google Play Protect can detect known versions of the malware. The developer of HandyPay is investigating the misuse of its application.

MiningDropper Android Malware Exploits Lumolight App

Researchers at Cyble Research and Intelligence Labs (CRIL) have discovered an Android malware framework called MiningDropper, which is being used in various campaigns to distribute malicious payloads such as cryptocurrency miners, infostealers, Remote Access Trojans (RATs), and banking malware. Over 1,500 MiningDropper samples were detected in one month, with many showing minimal antivirus detection. MiningDropper operates as a multi-stage delivery framework that employs techniques like XOR-based obfuscation and AES encryption to evade detection. A recent variant uses a trojanized version of the Lumolight application as the initial infection vector, often spread through phishing links and fraudulent websites. The malware executes a series of stages, starting with decrypting an embedded asset and loading additional payloads, including a counterfeit Google Play update interface to deceive users. Two main campaign clusters have been identified: an infostealer campaign targeting Indian users by impersonating trusted entities, and a global campaign distributing the BTMOB RAT, which enables credential theft and device takeover. The final payload capabilities include extracting sensitive data, enabling full device compromise, facilitating financial fraud, and unauthorized cryptocurrency mining. MiningDropper's modularity allows it to adapt and scale across various campaigns while maintaining low detection rates.

Mirax RAT Targets Android Devices Through Meta Apps

Mirax is a remote access Trojan (RAT) targeting Android devices in Spanish-speaking countries, identified by Outpost24's KrakenLabs in early March. It propagates fraudulent advertisements on Meta-owned applications, allowing cybercriminals to gain initial access. Mirax can interact with compromised devices in real time, converting them into residential proxy nodes through ads on platforms like Facebook and Instagram. It uses SOCKS5 protocol and Yamux multiplexing to establish proxy channels and uncover victims' IP addresses. The malware captures keystrokes, steals sensitive data, executes commands, and monitors user activity. It employs overlay pages to steal credentials and orchestrates distribution through Meta ads and GitHub for malicious APK files. Users are tricked into enabling installations from "unknown sources," and the malware disguises itself behind video playback features. Additionally, a threat actor has been offering Mirax as a malware-as-a-service (MaaS) on illicit forums, with subscription prices starting at ,500 for three months. This service is described as highly controlled and exclusive, primarily targeting Russian-speaking actors in underground communities.

“This was not opportunistic. It was precision.” — How North Korean hackers used Microsoft Teams and Slack to compromise Windows PCs with an elaborate ploy

On March 30, 2026, axios, a JavaScript HTTP client library, was temporarily compromised by suspected North Korean hackers who hijacked maintainer Jason Saayman's account. This allowed them to publish two malicious versions of axios on npm. The malicious versions were identified and removed within three hours by StepSecurity. A post-mortem blog on GitHub provided security measures for users of Windows, macOS, and Linux, highlighting risks from a Remote Access Trojan (RAT) introduced during the breach. The attack was attributed to a group known as UNC1069, which has been active since at least 2018. Two weeks prior to the breach, Saayman was targeted in a social engineering campaign where attackers posed as a legitimate company founder, leading him to install the RAT via a fake update during a Microsoft Teams meeting. Microsoft Teams was not compromised; it was used as a delivery method for the Trojan. Saayman noted the operation's sophistication.

‘NoVoice’ Android malware on Google Play infected 2.3 million devices

A new Android malware called NoVoice has been found in over 50 applications on Google Play, with more than 2.3 million downloads. The malware targets older Android versions, specifically those patched between 2016 and 2021, and attempts to gain root access by exploiting vulnerabilities. It conceals malicious components within the com.facebook.utils package and uses steganography to hide an encrypted payload within a PNG image file. NoVoice avoids infecting devices in certain regions and has checks to detect emulators and VPNs. Once activated, the malware contacts its command-and-control server to gather device information and polls it every 60 seconds for tailored exploits aimed at rooting the device. It can exploit 22 vulnerabilities, including kernel bugs, and establishes persistence by replacing key system libraries and installing recovery scripts. The malware injects code into applications, particularly targeting WhatsApp to extract sensitive data for session replication, which is then exfiltrated to the C2 server. The malicious apps containing NoVoice have been removed from Google Play, but users who installed them should consider their devices compromised. Upgrading to devices with later security patches is recommended to mitigate the threat.

RUSSIA Mammut virus hits Russia’s patriotic messaging app

A virus known as Mamont is targeting users of the messaging platform Max, which has 100 million registered profiles. Mamont infiltrates online banking applications and spreads primarily through family and parental chat groups, allowing cybercriminals to steal payment information. The virus often begins with a deceptive message prompting users to click, leading to the silent download of a Trojan that siphons off data. Despite claims from the Max press service that the virus's spread is exaggerated, concerns remain about the security of user data, particularly given that all communications on Max are monitored by the state. Many users resort to using a second device, referred to as Maxofon, to comply with the platform's requirements while keeping their primary device for other applications.
