Hackers Use Fake Purchase Orders to Deploy JS.MonoGlyphRAT Targeting US Enterprises

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.

Beware of Activating Them: 5 Android App Permissions That Pose a Threat to Your Data

Android applications often request various permissions upon installation, including access to the camera, microphone, contacts, messages, and accessibility features. Users frequently accept these requests without hesitation, which can compromise their device's privacy and security. Certain permissions, if granted to malicious apps, can enable monitoring of user activity, audio recording, location tracking, or unauthorized app installations. Five Android app permissions that require careful consideration before granting include: 1. Accessibility Services: Can allow untrusted apps to monitor screen content, read messages, track keystrokes, and perform actions on behalf of the user. 2. Display Over Other Apps: Allows apps to overlay content on other apps, which can be exploited by malicious apps to create deceptive interfaces. 3. Install Unknown Apps: Permits apps to install software from outside the Google Play Store, increasing the risk of malware. 4. Usage Data Access: Enables apps to monitor usage patterns, which can be used for targeted advertising or sold to data brokers. 5. Access to Contacts and Messages (SMS): Sensitive information can be intercepted by malicious apps, posing risks to account security. It is crucial to grant permissions that align with an app's intended function and to be cautious of unnecessary access.

Windows DNS Client Security Flaw Exposes Systems to Remote Code Execution

Windows systems are threatened by a vulnerability in the Windows DNS Client, identified as CVE-2026-41096, which allows remote code execution without user intervention. It has a CVSS base score of 9.8, indicating high severity. The flaw is a heap-based buffer overflow in the dnsapi.dll component, enabling unauthenticated remote attackers to execute arbitrary code. Exploitation requires sending a specially crafted DNS response to a vulnerable system, potentially leading to complete control over the host. Affected systems include supported versions of Windows 11 and Windows Server 2022/2025. Microsoft released security updates on May 12, 2026, and administrators are advised to apply these patches and reboot systems. Despite the severity, Microsoft currently classifies exploitation as “Exploitation Unlikely,” with no known public exploits or in-the-wild attacks.

You’re Going To Hate Google’s New Rules For Sideloading Android Apps

Google announced changes to the sideloading process for Android users, allowing "experienced" users to sideload applications through an opt-in system starting in November 2025. The new system includes an "advanced flow" that protects users from coercion and emphasizes individual choice. Users can sideload verified applications, those from developers with limited distribution, or from unverified sources, which requires a multi-step process including enabling developer mode, confirming the decision, restarting the device, and observing a 24-hour waiting period before enabling sideloading settings. A report indicated that less than 20% of Android users engaged in sideloading, suggesting most will continue using the Play Store. The changes are not expected to take effect until 2027, raising concerns about potential increased control over application distribution by Google.

Hackers Are Using Fake Invitations to Take Over Your PC

Cybercriminals are sending counterfeit email invitations that, when clicked, install a backdoor on the victim's computer, allowing hackers full control. The scam often involves downloading a file named “invites.msi,” which is a Windows Installer package. This file can install ScreenConnect, a legitimate remote support tool that can be exploited by attackers to monitor screens, access files, and deploy additional malware. Many security engines fail to flag this software as malicious, making it difficult to detect. If someone suspects they have fallen victim to this scam, they should disconnect from the internet, check for and uninstall any remote management software, run a comprehensive antivirus scan, change passwords for critical accounts, enable two-factor authentication, inform their IT department if applicable, and consider performing a full Windows reset. The scam originated from a compromised email account, which was used to send the malicious link to contacts. Implementing two-factor authentication and using a password manager can help prevent such incidents. Users should be cautious of any email invitations that require downloading and running installer files.
