Samsung Messages is going away, so here are 5 the best messaging alternatives

Samsung will officially cease operations of its Samsung Messages app in July 2026 and has stopped pre-installing it on newer Galaxy devices, including the Galaxy S26 series. Users can continue to send messages through the app until the shutdown, but emergency services and specific contacts will not be supported. Samsung is directing users to Google Messages as the official alternative, which supports Rich Communication Services (RCS) and is the default messaging app on most Android devices. Google Messages offers features such as reliable cross-texting with iPhone users, typing indicators, high-quality media sharing, message reactions, and built-in spam protection. Alternatives to RCS include WhatsApp, which offers voice and video calls, group chats, and message reactions, but has raised privacy concerns. Telegram allows large group chats, channels, and file sharing but lacks end-to-end encryption by default. Signal provides end-to-end encryption for all communications and collects minimal user data, making it the most secure option. Customizable SMS apps like Textra and QUIK SMS do not support RCS, making Google Messages the most viable option for RCS functionality.

Microsoft’s Patch Tuesday release for April is a whopper

A series of updates have been released, focusing on system integrity and performance. Users should perform verification tasks, including installing, uninstalling, and repairing MSI packages, connecting and disconnecting cloud sync providers, and enrolling devices in Intune or MDM solutions. The Common Log File System driver (clfs.sys) is receiving a follow-up patch, along with updates to Storage Spaces (spaceport.sys) and app isolation file system drivers (bfs.sys, wcifs.sys). Users should also run Windows Update installation and rollback cycles, install and uninstall applications, and verify data integrity through backup solutions. For Storage Spaces, creating a pool with mirrored and thin virtual disks and ensuring clean deletion is necessary. April's updates for Office target MSI editions, including Excel 2016 (KB5002860), PowerPoint 2016 (KB5002808), Office 2016 shared libraries (KB5002859), and SharePoint Server editions from 2016 to 2019. These updates do not apply to Click-to-Run deployments like Microsoft 365 Apps. Users should validate complex Excel workbooks, PowerPoint presentations, SharePoint document libraries, and the functionality of Office add-ins. Testing for two High Risk components is essential: changes to Kerberos may disrupt services using RC4 keytabs, and the Remote Desktop client update requires validation of clipboard functionality, printer redirection, and session reconnection. Validating Secure Boot and BitLocker is critical as CVE-2023-24932 key rolling progresses. Additionally, cloud sync testing is important due to five patches to the Projected File System driver, and regression testing is needed for dual afd.sys updates and VPN/IPsec patches across remote-access infrastructure. Office updates are limited to MSI editions.

RedSun: Windows 0day when Defender becomes the attacker

A vulnerability has been discovered in Windows Defender that allows standard users to exploit a logic error in the file remediation process, enabling code execution with elevated privileges without administrative access. This flaw, identified by security researcher Chaotic Eclipse, occurs because Windows Defender does not verify if the restoration location of flagged files has been altered through a junction point. The exploit, named RedSun, takes advantage of a missing validation in the MpSvc.dll file, allowing attackers to redirect file restoration to the C:WindowsSystem32 directory. RedSun operates by chaining together four legitimate Windows features: Opportunistic Locks (OPLOCKs), Cloud Files API, Volume Shadow Copy Service (VSS), and Junction Points. The execution of the exploit involves monitoring shadow copies, triggering Defender's detection, synchronizing OPLOCKs, and ultimately writing malicious binaries to the System32 directory. The root cause is the lack of reparse point validation in the restoration process, and currently, no patch or CVE has been assigned for this vulnerability. It affects Windows 10, Windows 11, and Windows Server 2019 and later, and organizations are advised to implement behavioral detection strategies until a fix is available.

Why Postgres wants NVMe on the hot path, and S3 everywhere else

Efforts to merge storage roles into a single solution are ongoing, particularly with Amazon S3's durability and cost-effectiveness. In PostgreSQL, achieving a durable commit requires flushing the Write-Ahead Log (WAL) before signaling transaction completion, which can take tens of microseconds on high-performance NVMe drives but extend to milliseconds on slower storage. This latency impacts Online Transaction Processing (OLTP) systems and user response times. Benchmark studies show that systems with faster local storage outperform those with slower alternatives as workloads exceed memory capacity. The fsync operation in PostgreSQL is a commitment rather than a simple write, with enterprise-grade SSDs performing better due to power-loss protection. Read operations also face challenges, as PostgreSQL's need for small, latency-sensitive reads conflicts with S3's design for larger, higher-latency requests. As the working set exceeds memory, storage latency becomes a critical performance factor. Modern managed PostgreSQL systems typically do not place object storage in the critical commit path, instead maintaining a fast log or cache close to the database while relegating colder data to remote storage. Recent PostgreSQL developments, such as asynchronous I/O support in version 18, aim to leverage fast storage more effectively. S3 is valuable for tasks like WAL archiving and backups, but these should be kept separate from the commit path to avoid resource contention. The solution involves using both NVMe and S3, with fast storage managing commits and cache misses, while object storage handles archives and backups. PostgreSQL performs best when hot and cold storage functions are clearly delineated.

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.
