No firewalls or antivirus software—this new quantum technology using magnets promises to protect your information at the subatomic level

A team from Kyoto University has developed a light source that emits single photons, enhanced in brightness by a small magnetic field, which can be used for secure quantum communications. This technology relies on the principles of quantum mechanics, making it difficult for eavesdroppers to replicate or measure the quantum states without detection. The researchers used a one-atom-thick semiconductor sheet, WSe₂, creating traps for excitons that emit photons when relaxed. Current limitations include the need for cryogenic temperatures for operation, but advancements in materials may allow for room-temperature single-photon emission. The technology has potential applications in secure communications for sensitive transactions and could evolve into compact modules for practical use. Recent studies have demonstrated successful quantum key distribution (QKD) using true single-photon sources, indicating progress in integrating quantum technology into real-world networking.

Updating your Linux kernel sounds scary, but here’s why it’s no different from a Windows update

Updating the Linux kernel is generally straightforward and low-risk, similar to Windows updates. Most Linux distributions, including Ubuntu, Fedora, Debian, and Linux Mint, manage kernel updates automatically through the package manager. When a new kernel is installed, the previous version remains intact, allowing users to revert to it if necessary via the GRUB boot menu. Kernel updates provide essential security patches, bug fixes, and improved hardware support. While manual installation of a kernel is possible, it is not required for most users. Tools are available for easier management of kernel versions, but the update process is designed to be user-friendly and safe.

New Android Malware Poses as SBI Card and Axis Bank Apps to Steal Financial Data

McAfee’s Mobile Research Team has identified a malware campaign targeting Android users in India, specifically Hindi speakers. The malware disguises itself as legitimate financial applications from banks like SBI Card, Axis Bank, and IndusInd Bank. It is distributed through phishing websites that mimic official banking portals and uses authentic assets to appear credible. The malware has dual functionality: it exfiltrates personal and financial data and mines Monero cryptocurrency using the XMRig tool, activated remotely via Firebase Cloud Messaging (FCM). It masquerades as a Google Play update, prompting users to install it, which leads to data theft. Upon installation, the malware presents a fake Google Play interface and requests sensitive information, which is sent to a command-and-control server. After data submission, users see a misleading confirmation page. The malware employs a multi-stage dropper to evade detection, with remote activation capabilities that keep it dormant until triggered. Phishing sites promote the malicious APK through SMS, WhatsApp, or social media. McAfee has reported these threats to Google, resulting in the blocking of the associated FCM account. All variants are classified as high-risk, with infections primarily in India but some in other regions. Users are advised to download apps only from Google Play and to be cautious with unsolicited links. Indicators of Compromise (IOCs) include specific APKs for various credit cards and phishing site URLs related to the campaign.

Malware disguises itself as an innocent photo on Dropbox. APT37’s steganographic strategy

Specialists at the Genians Security Center have identified a new version of the RoKRAT malware linked to the North Korean APT37 group. This version uses steganography to hide its code in JPEG images, allowing it to bypass antivirus systems. The infection begins with a malicious .LNK link in a ZIP archive, which contains a large .LNK file that misleads users. The malware employs various encrypted components, including shellcode, PowerShell scripts, and batch files. Upon execution, PowerShell decrypts the shellcode using a XOR operation, and the malware injects itself into legitimate Windows processes without leaving traces on the disk. The RoKRAT loader is embedded in a JPEG image hosted on Dropbox, and it uses a double XOR transformation to extract the shellcode. The malware is activated through sideloading techniques using legitimate utilities and downloads from cloud platforms. RoKRAT can collect data, take screenshots, and transmit them to external servers. Recent samples have targeted “notepad.exe” for code injection, indicating ongoing development. Endpoint detection and response (EDR) systems are essential for monitoring unusual activities and protecting against these sophisticated attacks, as traditional defenses are inadequate.
