Beginning in May 2026, Microsoft will introduce Hotpatching as a default feature for compatible systems, allowing security updates to be applied without requiring a restart. Hotpatching updates code directly in the memory of running processes, enabling selective updates without interrupting the entire system. It does not replace monthly security updates but alters their activation process on eligible systems, categorized as security updates within the monthly B releases. Eligible systems must be running Windows 11 version 24H2 or newer and possess suitable licenses such as Enterprise, Education, Microsoft 365, or Windows 365. Management of these updates will be facilitated through Windows Autopatch or Microsoft Intune. Microsoft will continue to utilize baseline updates that require a restart, which will alternate with Hotpatch months. Hotpatching aims to reduce the frequency of restarts tied to security updates, particularly benefiting environments where uptime is critical. However, planned restarts will still be necessary, and robust telemetry and maintenance practices will be needed to ensure smooth operation.

ScarCruft compromised a video game platform in a supply chain attack, trojanizing its components with a backdoor called BirdCall to target ethnic Koreans residing in China. The attack enabled the threat actors to target both Windows and Android devices, turning it into a multi-platform threat. The campaign targeted sqgame[.]net, a gaming platform used by ethnic Koreans in China, known as a transit point for North Korean defectors. BirdCall has features like screenshot capture, keystroke logging, and data gathering, and relies on legitimate cloud services for command-and-control. The Android variant collects various data and has seen active development.

Meta has enhanced the security and transparency of its end-to-end encrypted backup system for WhatsApp and Messenger. The improvements focus on refining the distribution and verification of encryption keys, and allow for independent audits of certain infrastructure components. The updates are based on Meta's Hardware Security Module (HSM)-based Backup Key Vault architecture, which securely stores recovery secrets in tamper-resistant hardware, ensuring that neither Meta nor cloud service providers can access users' message archives. For encrypted backups, users' devices generate a 256-bit encryption key locally, which encrypts all backup data before uploading it to cloud storage. The key remains on the device in an encrypted format, with the user's password not visible to Meta or third parties. An encrypted version of the backup key is stored in the HSM-based vault using the OPAQUE password-authenticated key exchange protocol, enhancing recovery security without revealing the password. The recent updates include an over-the-air (OTA) fleet key distribution mechanism, which avoids hardcoding trusted infrastructure keys into Messenger applications. Clients receive a “validation bundle” containing the HSM fleet's public keys during runtime, with signatures verified against Cloudflare’s Key Transparency system. The vault operates across at least seven data centers using majority-consensus replication to ensure availability and integrity. Meta plans to publish cryptographic proof of each new HSM fleet deployment, allowing advanced users and researchers to verify these deployments through the open-source “mbt” (Meta Binary Transparency) CLI tool, which conducts multiple checks to confirm that fleet keys are untampered.

APT37, also known as ScarCruft and Ricochet Chollima, has developed an Android version of the backdoor BirdCall, which serves as spyware in addition to a backdoor. The malware was delivered through a Chinese website that hosts games for Android, iOS, and Windows, targeting only Android and Windows systems. The Android variant of BirdCall has capabilities such as extracting IP geolocation information, collecting contact lists, call logs, SMS data, device information, taking screenshots, recording audio, and exfiltrating files. Users are advised to download software only from official marketplaces and trusted publisher sites to protect against malware infections.

Linux has been successfully implemented on the PlayStation 5, allowing users to run an open operating system on the console. This implementation, led by security researcher Andy Nguyen (TheFlow), utilizes an exploit for PS5 consoles with system software versions up to 4.5. Users can boot Linux from a USB or SSD, with Ubuntu 26.04 LTS providing around 15GB of usable memory. The PS5's hardware, including its Zen 2 processor and GPU, is fully accessible, with CPU speeds reaching up to 3.5GHz and GPU speeds up to 2.23GHz when boost mode is activated. However, running Linux on the PS5 presents challenges, such as sourcing a unit with the required firmware and limitations in resolution, as users cannot exceed 1080p. Performance tests showed that Linux can match the PS5's performance in some titles, but issues with memory management were noted, leading to stuttering and crashes in certain games. For example, reducing texture quality improved performance in games like Pragmata, while rendering issues were observed in Crimson Desert. The implementation allows for a unique gaming experience, but it also highlights the complexities and limitations of running Linux on a gaming console.
