New variants of the NFCShare Android malware are disguised as fake updates for legitimate banking applications and are targeting customers of various banks in Europe through a phishing campaign to steal sensitive payment card data. The malware prompts victims to place their cards near the NFC chip of their mobile devices, using Android’s IsoDep interface to read card information, including card number, type, expiry date, and a 4-digit PIN. The stolen data is exfiltrated to the attacker’s command-and-control host via a WebSocket channel. Recent attacks began on May 14, with victims directed to a phishing site that impersonates a legitimate bank and then to a GitHub repository hosting a malicious APK file. The repository has hosted 56 unique APKs impersonating banking applications primarily from Italy and Spain. The malware has evolved from initially targeting Deutsche Bank in Germany to a broader range of banks. The latest version features malformed APK packaging to complicate automated analysis. Users are advised to download banking applications only from Google Play and to be cautious of verification requests that ask for NFC card scans.

OneLaunch is a software application that creates a personalized dock and desktop environment on Windows computers, often pre-installed or bundled with other software. It has received mixed reviews, with concerns about system slowdowns and its legitimacy. OneLaunch.exe is a background process supporting the OneLaunch application, which provides quick access to applications and updates but can consume system resources. The OneLaunch browser, installed alongside the main application, can alter browser settings and redirect searches, potentially leading to unwanted advertisements. While OneLaunch is not classified as traditional malware, it is often categorized as a Potentially Unwanted Program (PUP) due to its bundled installation and ability to modify system settings. It can monitor browsing habits and share data with third-party advertisers. Users report intrusive behavior, such as altering default browser settings, and it can negatively impact system performance. To remove OneLaunch, users should end the running process, uninstall the application, delete leftover folders, remove startup entries, and reset browser settings. OneLaunch may reappear due to accidental reinstallations, active browser extensions, lingering scheduled tasks, or hidden companion programs. Preventative measures include downloading from official sources, reading installation screens carefully, keeping systems updated, and performing regular system checks.

Researchers have identified a new malware called JS.MonoGlyphRAT, which disguises itself as business documents to infiltrate corporate networks. It is primarily spread through phishing emails targeting various sectors in the U.S. and has been reported in countries like Germany, Sweden, and Australia. The malware is classified as "Unknown malware" on threat intelligence platforms, making traditional antivirus solutions ineffective. It establishes a persistent presence in the network by executing a JavaScript file and communicating with command-and-control (C2) servers over HTTP. Key indicators of compromise include unusual HTTP traffic, registry changes, and the execution of specific JavaScript files. The malware can download additional payloads and execute commands without leaving traces on disk. Indicators of compromise include specific IP addresses, URLs, file hashes, and registry keys associated with the malware's operation.

In April 2026, a blog post from Microsoft's Windows Learning Center claimed that most Windows 11 users could rely solely on Windows Security (Defender) for antivirus protection, citing features like Microsoft Defender Antivirus, SmartScreen, and ransomware mitigation. The blog was later removed without explanation, leading to speculation about its definitive claims. Microsoft stated that Windows Defender was sufficient for typical users with default settings and regular updates, while cautioning against using multiple antivirus engines. Independent testing from AV-Test consistently ranks Microsoft Defender highly, but AV-Comparatives noted limitations in offline protection and the reliance on cloud-based intelligence. The blog's removal was viewed by some as a constructive step towards realistic security guidance. Microsoft continues to provide third-party antivirus vendors with significant access to Windows, and the rise of AI-generated threats is complicating the cybersecurity landscape. Despite the controversies, Microsoft has made significant advancements in Windows Security, making it a viable option for many users.
