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.

NGate Android malware uses HandyPay NFC app to steal card data

A new variant of the NGate malware targets Android users by disguising itself within a trojanized version of the HandyPay app, which is a legitimate mobile payment processing application. This malware, documented since mid-2024, siphons payment card information through the mobile device's near-field communication (NFC) chip and sends the stolen data directly to attackers, who create virtual cards for unauthorized purchases or cash withdrawals from NFC-enabled ATMs. The new variant has been injected with malicious code into the HandyPay app, which has been available on Google Play since 2021. The code includes emojis, indicating the possible use of a generative AI tool in its development. The shift from previous iterations, which used an open-source tool named NFCGate, to HandyPay is likely motivated by financial considerations and the need for evasion, as HandyPay is more affordable and requires fewer permissions. This NGate variant has been active since November 2025, primarily targeting Android devices in Brazil. It employs two main distribution methods: a counterfeit app named “Proteção Cartão” hosted on a fraudulent Google Play page and a fake lottery website that redirects users to WhatsApp to download the malicious APK. Upon installation, the app prompts users to set it as their default NFC payment application, requests their card PIN, and instructs them to tap their card on the phone for reading, transmitting all collected information to an attacker's email address. To protect against such threats, Android users are advised to avoid downloading APKs from outside Google Play, disable NFC when not in use, and use Play Protect to scan for threats.

NGate NFC malware targets Android users through trojanized payment app

NFC-based payment fraud targeting Android users in Brazil has been linked to a campaign using a trojanized version of the HandyPay app, part of the NGate malware family, since November 2025. The malware is distributed through a counterfeit website mimicking a lottery and a fraudulent Google Play page. The operators chose HandyPay for its low cost and minimal permissions required. The malware requests users to set it as the default NFC payment app, allowing it to capture payment card PINs and relay NFC card data to attackers. ESET Research identified this campaign and discovered logs from compromised devices containing sensitive information. The trojanized app has never been on the official Google Play store, and ESET has notified Google and the HandyPay developer about the issue.

New NGate Android malware variant uses NFC app to steal card data

A new variant of the NGate Android malware exploits a legitimate NFC payment app, HandyPay, to steal users' card information and PINs, enabling unauthorized contactless transactions. This malicious version of HandyPay, which has been available since 2021, was identified by ESET researchers and is distributed through a fraudulent lottery website and a fake Google Play page. The malware captures sensitive information by prompting users to enter their payment card PIN and tap their card against the device, sending the data to an attacker-controlled phone and exfiltrating the PIN to a command-and-control server. The campaign employs social engineering tactics and requires minimal permissions, relying on users to enable app installations from unknown sources. The attackers use a centralized infrastructure for malware distribution and PIN collection, with evidence of compromised devices in Brazil. The shift to modifying a legitimate application is motivated by financial incentives, as it offers similar functionality at a lower cost compared to underground tools. Users are advised to avoid installing apps from unofficial sources and to ensure the legitimacy of applications before entering sensitive information.

New RecruitRat, SaferRat, Astrinox, Massiv Android Malware Found Targeting 800 Apps

Cybersecurity researchers from Zimperium zLabs have identified four families of Android malware—RecruitRat, SaferRat, Astrinox, and Massiv—targeting banking and cryptocurrency applications. These malware families can extract sensitive information from over 800 applications. They primarily use phishing and smishing to lure users into downloading malicious software. Phishing involves creating fake websites resembling legitimate login pages, while smishing uses urgent text messages with links to download harmful payloads. RecruitRat targets job seekers with fake employment websites, and SaferRat promises free access to premium video services. Astrinox mimics a business tool and has been linked to a fraudulent Apple App Store page, while Massiv's distribution methods remain unclear. Once installed, these malware applications initiate Overlay attacks, displaying counterfeit screens to capture user credentials. They also use a "blindfold" technique to obscure their activities by overlaying static images on the user's screen. The malware can intercept security codes, capture one-time passwords, and employ keylogging techniques. RecruitRat has a library of over 700 counterfeit login pages that activate with targeted apps. Researchers recommend avoiding links in urgent messages and downloading apps only from official sources.

Fake Proton VPN sites are pushing NWHStealer malware to Windows users

A malware campaign is utilizing counterfeit Proton VPN websites and other deceptive tactics to distribute a Windows infostealer known as NWHStealer. This malware extracts sensitive information, including browser credentials and cryptocurrency wallet details, and operates stealthily by injecting itself into legitimate processes. Two primary infection vectors have been identified: malicious ZIP archives on a free web hosting platform and trojanized installers from fake Proton VPN sites. The malware employs DLL hijacking and can exfiltrate data to a command-and-control server while ensuring persistence through scheduled tasks and disguising payloads as legitimate system processes. It also exploits the Windows cmstp.exe utility to bypass User Account Control. Users are advised to avoid downloading software from unofficial sources and to verify file signatures and publisher information.

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.

Fake Claude site installs malware that gives attackers access to your computer

Claude, an AI tool developed by Anthropic, receives nearly 290 million web visits monthly and has become a target for cybercriminals. A fake website has been found that impersonates Claude, distributing a trojanized installer named Claude-Pro-windows-x64.zip. This installer, while appearing legitimate, deploys PlugX malware, granting attackers remote access to users' systems. The fraudulent site mimics the official download page and uses passive DNS records linked to commercial bulk-email platforms, indicating active maintenance by the operators. The ZIP file contains an MSI installer that incorrectly spells "Claude" as "Cluade" and creates a desktop shortcut that launches a VBScript dropper. This script runs the legitimate claude.exe while executing malicious activities in the background, including copying files to the Windows Startup folder to ensure persistence after reboot. The attack utilizes a DLL sideloading technique recognized by MITRE as T1574.002, where a legitimate G DATA antivirus updater is exploited with a malicious DLL. Within 22 seconds of execution, the malware establishes a connection to an IP address associated with Alibaba Cloud, indicating control over the compromised system. The dropper script also employs anti-forensic measures to delete itself and the VBScript after deployment. Indicators of compromise include the filenames Claude-Pro-windows-x64.zip, NOVUpdate.exe, avk.dll, and NOVUpdate.exe.dat, along with the network indicator 8.217.190.58:443 (TCP) as the command and control destination. Users are advised to download Claude only from the official site and to remain vigilant against potential compromises.
