Surge in Android Malware Targets Banking Apps with NFC Fraud

A new wave of Android malware is targeting banking applications, utilizing techniques such as NFC relay fraud, call hijacking, and root-level exploits. Variants like PhantomCard, SpyBanker, and KernelSU are designed to infiltrate devices and manipulate transactions in real time. PhantomCard mimics legitimate NFC payment processes, SpyBanker hijacks calls from financial institutions, and KernelSU exploits kernel vulnerabilities for persistent access. This malware has affected thousands of devices, with attackers using disguises on the Google Play Store and phishing campaigns. A related variant, Anatsa, impacted over 90,000 users through fake PDF applications. The rise of such malware correlates with the increasing adoption of contactless payments, particularly in Europe and Asia. Experts recommend that banks enhance their defenses with behavioral analytics and that users enable app verification. Additionally, malware like KernelSU allows evasion of detection by operating at the system's core. Cybersecurity firms suggest a multi-layered security approach, including device encryption and AI-driven threat detection, to combat these evolving threats.

Beware of this Android antivirus. It actually steals data, records audio, and tracks you

LunaSpy is a deceptive antivirus application that spreads primarily through Telegram and is not available on the official Google Play Store. It masquerades as a legitimate antivirus program, claiming to protect online banking activities. Upon installation, it conducts a superficial scan and displays false warnings to instill fear, prompting users to grant extensive permissions. Once installed, it can invade personal data, access banking information, record audio and video, steal passwords, read SMS messages, track locations, and has been found to include a command for photo theft. Users are advised to avoid downloading LunaSpy and to exercise caution with applications from social networks or unofficial sources, relying instead on verified antivirus solutions from official app stores.

Fake Minecraft Installer Spreads NjRat Spyware to Steal Data

Point Wild’s Lat61 Threat Intelligence Team has identified a new cyber threat targeting Minecraft fans, involving malware disguised as a Minecraft installer that steals personal data. This threat is associated with an unofficial browser-based Minecraft clone called Eaglercraft 1.12 Offline, commonly used in schools. The malware, a Remote Access Trojan (RAT) named NjRat, can capture keystrokes, access webcams and microphones, and establish a backdoor in the system by adding a hidden program called WindowsServices.exe to startup files. It can crash the system to avoid detection by security tools. The attack begins with a malicious file that, when executed, distracts the user with a fake game while downloading harmful files in the background. The malware connects to a remote server in India, allowing attackers to control the infected computer and extract data. Users are advised to download Minecraft only from official sources and be cautious with third-party applications.

You should deep clean your Windows PC every year to keep it running smoothly — here’s how I do it

Maintaining a computer's performance requires regular software upkeep in addition to physical care. An annual deep clean is advisable, with more frequent maintenance being beneficial. 1. Uninstall unused applications using the built-in Settings app or a tool like BCUninstaller, which can bulk uninstall and identify leftover files. 2. Run debloat scripts, such as Chris Titus Tech's Windows Utility, to remove bloatware and manage privacy settings. 3. Disable unnecessary startup apps through the Task Manager to optimize boot times. 4. Check for driver updates manually under Advanced options > Optional updates, and visit manufacturer websites for graphics drivers. 5. Run a malware scan using MalwareBytes for periodic checks. 6. Delete temporary files via System > Storage > Temporary files in the Settings app, and manage cached files in web browsers.

Your antivirus is under attack from new “killer” tool – here’s what we know

Cybercriminals are enhancing their capabilities to disable antivirus and endpoint detection and response (EDR) systems, with a new malware tool called EDRKillShifter being circulated in underground forums. This tool can neutralize EDR systems from vendors like Sophos, Bitdefender, and Kaspersky, using obfuscation techniques and signed drivers that may be stolen or compromised. EDRKillShifter was found embedded in the legitimate Clipboard Compare tool from Beyond Compare, indicating sophisticated tactics to evade detection. The malware emerged in mid-2024 after an unsuccessful attempt to disable antivirus software and deploy ransomware, revealing evolving strategies among attackers. To mitigate risks, Sophos recommends enabling tamper protection, maintaining robust security hygiene, and keeping systems updated, particularly regarding outdated signed drivers.

Windows DoS Flaws Enable DDoS Attacks on Domain Controllers

Researchers from SafeBreach Labs have identified four denial-of-service (DoS) vulnerabilities in Microsoft’s Windows operating system that could allow attackers to use publicly accessible Windows domain controllers in distributed denial-of-service (DDoS) attacks. These vulnerabilities exploit protocols such as Remote Procedure Call (RPC) and Lightweight Directory Access Protocol (LDAP), enabling the creation of stealthy botnets without authentication. The flaws arise from improper handling of RPC and LDAP requests in Windows Server environments, including versions up to 2025. One flaw allows unauthenticated users to trigger infinite loops, consuming system resources and facilitating reflection attacks. Microsoft released patches for these vulnerabilities in August 2025, but unpatched systems remain at risk. The vulnerabilities were disclosed at DEF CON 33, where proof-of-concept attacks were demonstrated. SafeBreach has labeled these flaws as “Win-DoS” due to their widespread applicability. Organizations are advised to audit network exposures and isolate domain controllers to mitigate risks. The increase in hyper-volumetric DDoS attacks highlights the urgency for proactive defenses, including automated mitigation tools and regular vulnerability scans. Experts recommend implementing stringent firewall rules to restrict RPC and LDAP exposure and using behavioral analytics to detect anomalous traffic.
