50+ Samsung Galaxy Store apps spread phone malware

Samsung's Galaxy Store had over 50 applications that unknowingly distributed a hidden Android trojan named MagicAd, which has since been removed. Users who downloaded these apps may still have the malware on their devices, as it establishes persistent background services that remain after the app is uninstalled and hides its icon. Signs of infection include unsolicited ads, battery drain, and unexplained data usage. The malware evades detection by assessing its environment and concealing its core code in encrypted files. Developers rotated the infected apps to maintain persistence and generated revenue through fraudulent ad impressions. Users are advised to run security scans and consider a factory reset if symptoms persist, ensuring to back up important files without including app settings. No app store can guarantee the exclusion of all threats, so users should check ratings and download counts before installing applications.

China-Linked SprySOCKS Backdoor Expands to Windows with Driver-Based Stealth

Cybersecurity researchers have identified two new Windows variants of the SprySOCKS backdoor, named WINDRV and WINPLUS, which were previously thought to be exclusive to Linux systems. Both variants feature hard-coded command-and-control configurations and can communicate via TCP, UDP, and WebSocket protocols. They support over 30 commands for operations such as system information collection and file management. WINDRV employs kernel drivers for stealth, obscuring network connections and allowing TCP traffic diversion. SprySOCKS was first documented by Trend Micro in September 2023, linked to the Chinese state-sponsored threat actor Earth Lusca, also known as FishMonger. The Windows variants belong to version 1.8 of SprySOCKS and utilize a kernel driver named RawWNPF for enhanced stealth. The attack chain begins with an initial access method that drops a batch script, leading to the installation of the backdoor. Evidence suggests these variants may have been used in attacks against government organizations in Honduras, Taiwan, Thailand, and Pakistan between 2023 and 2024. The WINPLUS variant was first detected in July 2024 in Pakistan. There are indications of a potential UEFI bootkit involvement exploiting CVE-2023-24932, a vulnerability in the Windows Boot Manager.

1 Million Users Donate To Rescue Session Messenger From Shutdown

Session, a decentralized encrypted messenger, has over a million monthly users and has secured its future through community donations after facing a funding crisis earlier this year. The Session Technology Foundation had to reduce its paid staff and warned of a potential closure in July due to a significant financial shortfall. However, the community raised sufficient funds to prevent shutdown, allowing development to continue until at least 2027. The majority of contributions came from everyday users passionate about privacy communication. Session operates without requiring phone numbers and uses a decentralized network to enhance privacy. Under the leadership of Jason Rhinelander, the team is focusing on new features like post-quantum encryption. The organization also aims to achieve self-sustainability with a new paid Pro tier. Co-founder Chris McCabe's public appeal for support in March preceded staff layoffs on April 9, and Ethereum co-founder Vitalik Buterin previously donated 128 Ether (ETH) to assist the foundation.

New Windows Zero‑Day Flaws Target Defender and BitLocker

A cybersecurity researcher known as “Nightmare Eclipse” has revealed two zero-day exploits threatening Windows systems: RoguePlanet and GreatXML. RoguePlanet targets Microsoft Defender, allowing attackers to execute privileged actions and gain SYSTEM-level access on Windows machines. It is a local privilege escalation vulnerability that remains effective on fully updated systems. GreatXML claims to bypass BitLocker disk encryption by manipulating the Windows Recovery Environment, potentially granting access to protected files. However, its effectiveness may be overstated, as it might require administrator-level access. Microsoft advises organizations to implement security updates, treat lost or accessible devices as high-risk, enforce stricter policies, and monitor threat intelligence to mitigate exposure to these vulnerabilities.

Over 50 Android Apps Found Spreading MagicAd Trojan via Official Stores

A trojan named Android.MagicAd.1 has been identified as a significant threat to Android users, capable of delivering persistent background advertisements by circumventing built-in defenses. Detected in 2025, it has spread through over 50 infected games and utility applications, infiltrating both dubious download sites and official app stores like the Samsung Galaxy Store and Xiaomi’s GetApps. The malware employs a strategy of rotating applications to evade detection, remaining active on user devices after download. It uses hidden, encrypted components within native code libraries and conducts environment checks to avoid monitoring before launching its payload. Android.MagicAd.1 bypasses Android's restrictions by targeting trusted system applications, utilizing methods that vary by device manufacturer. For example, it uses a delayed system command on Xiaomi and Amazon devices, exploits Android Binder on Vivo devices, and employs a universal fallback method for other brands to gain priority for displaying ads. All identified malicious applications have been removed from official stores, but the campaign highlights the vulnerability of security software.

Windows Server is getting new network safety capabilities with DNS over HTTPS

Microsoft has introduced DNS over HTTPS (DoH) on Windows Server 2025, enhancing network security by encrypting DNS traffic for client-to-server communications. This feature, previously available only in Windows client editions, is now part of Microsoft's Zero Trust architecture. DoH routes DNS traffic through HTTPS secured with TLS certificates, preventing eavesdropping and safeguarding DNS data from tampering. It adheres to the IETF DNS over HTTPS standard (RFC 8484) and can integrate with existing infrastructure, allowing organizations to maintain unencrypted DNS traffic if needed. DoH is available for Windows Server 2025 systems updated to the latest Patch Tuesday release, and Microsoft has provided guidance on enabling this feature. However, DNS traffic exchanged between two DNS servers will not be encrypted by DoH.

Windows Server 2025 Adds DNS Over HTTPS for Secure DNS Traffic

Microsoft has rolled out support for DNS over HTTPS (DoH) in Windows DNS Server as part of the Windows Server 2025 update. This feature enhances the security of DNS communications through encryption and server authentication, allowing encrypted client-to-resolver traffic in on-premises DNS environments. DoH encrypts DNS queries and responses using HTTPS, protecting sensitive information from interception or alteration. It also uses digital certificates for DNS server authentication to reduce spoofing and impersonation risks. The feature is compatible with existing Windows DNS Server configurations and supports both encrypted and traditional DNS. DoH support is available on Windows Server 2025 with the June 9, 2026 update or newer. Administrators must configure a trusted TLS certificate and enable DoH in the DNS Server service to deploy this feature. Microsoft plans to extend encryption capabilities to include communication between the Windows DNS Server and upstream DNS resolvers in the future.

Hackers Use Fake Windows Update Installers to Deliver OnyxC2 Credential Stealer

OnyxC2 is a sophisticated credential stealer available for a subscription fee of 0 per month, distributed through disguised lures such as fake Windows updates and legitimate software installers. It functions as a commercial product with features like an automated payload builder, tiered licensing, and a centralized web dashboard. The malware boasts a 99% detection-evasion rate, successfully evading major antivirus solutions during tests. It is developed in C++, utilizing direct system calls and mutating with each build to avoid detection. OnyxC2 collects data from around 210 applications, targeting 45 web browsers, password managers, cryptocurrency wallets, and FTP clients. The malware is delivered using DLL sideloading, where a password-protected archive contains a legitimate application and a malicious DLL. The attacker's DLL is disguised by inflating its size and is loaded by a trusted binary. The malicious code remains encrypted on disk and decrypts in memory to evade analysis. OnyxC2 communicates with a Cloudflare-fronted command-and-control server to manage infected hosts and execute commands like hardware registration and cookie uploads. The threat extends to business environments, targeting FTP and email clients, with stolen session cookies allowing ongoing access to corporate infrastructure. Implementing anti-data exfiltration controls is recommended as a mitigation strategy.

Microsoft fixes BitLocker recovery bug on Windows Server 2025

Microsoft has resolved an issue affecting certain Windows Server 2025 devices that were booting into BitLocker recovery mode after the April 2026 security update. This issue was linked to specific BitLocker Group Policy configurations and required users to input their BitLocker recovery key upon the first restart after the update. However, this key would only need to be entered once for subsequent restarts, provided the group policy configuration remained unchanged. The problem primarily affected enterprise systems rather than personal devices. The issue arose under specific conditions: BitLocker was enabled on the operating system drive, a particular Group Policy was set, the Secure Boot State PCR7 Binding was "Not Possible," the Windows UEFI CA 2023 certificate was present, and the device was not already using the 2023-signed Windows Boot Manager. Microsoft released fixes in the KB5094125 and KB5093998 updates to address this problem, preventing devices with incompatible group policy configurations from installing the 2023-signed Windows Boot Manager. Event ID 1032 in the System event log indicates the issue when Windows updates are installed. For IT administrators unable to deploy the latest updates, it is recommended to remove the Group Policy configuration before installing updates or to implement a Known Issue Rollback (KIR) on affected devices. Additionally, Microsoft had previously addressed similar BitLocker recovery issues in August 2024 and May 2025.
