Что такое троттлинг и как понять, что провайдер намеренно замедляет ваш трафик

Throttling is the intentional limitation of speed for specific types of traffic, services, protocols, devices, or users. It can occur due to various reasons, such as exceeding data caps, prioritization of certain services, load management during peak hours, or technical policies in networks. Users may experience speed drops that are selective to specific traffic types, indicating potential throttling, while universal slowdowns suggest network overload or outages. Speed tests measure connectivity to specific servers and may not reflect actual download speeds across different paths. Signs of potential throttling include isolated speed drops, consistent slowdowns at specific times, and discrepancies between speed tests and real-world performance. Initial checks should rule out home network issues, and practical diagnostics can help identify throttling by comparing speeds across different servers, types of downloads, and times of day. If throttling is confirmed and support does not resolve the issue, exploring alternative ISPs may be necessary.

LabubaRAT malware infiltrates Windows systems while posing as NVIDIA software

LabubaRAT is a newly identified Rust-based remote access tool (RAT) that disguises itself as NVIDIA software to facilitate operations on Windows systems. It establishes a reusable foothold for hands-on activity and can profile the host system, identify security tools, execute commands, transfer files, capture screenshots, and proxy network traffic. LabubaRAT retrieves its configuration at launch via command-line arguments or environment variables, allowing operators to specify parameters like the command-and-control server and API key at runtime. It maintains local state in a SQLite database and supports communication through HTTPS polling, Microsoft Edge WebView2, and DNS tunneling. The malware includes capabilities for command execution, file handling, and establishing persistence through a Windows Run registry key. The entry point for the attack is an executable named nvidia-sysruntime.exe, which masquerades as NVIDIA’s container runtime toolkit. LabubaRAT conducts thorough profiling of the host, checking for installed browsers and security products, and gathers information on the system's specifications. Blackpoint Cyber has shared indicators of compromise to help detect LabubaRAT activity.

Study of 281 Free Android VPN Apps Finds Traffic Leaks, Unencrypted Data, and Tracking

Researchers analyzed 281 popular free VPN applications on the Google Play Store and found significant privacy and security shortcomings. The study, conducted by teams from the University of Michigan, the University of New Mexico, and IIT Delhi using a framework called MVPNalyzer, revealed that flagged apps had over 2.4 billion downloads. Key findings included: - Five apps transmitted configuration files unencrypted, allowing attackers to intercept and modify them. - 29 apps allowed user traffic to leak outside the encrypted tunnel, with 24 leaking DNS traffic and six leaking full browsing traffic. - 169 apps made no effort to disguise their traffic, making it identifiable to network operators or government censors. - 76 apps transmitted the device's Advertising ID to advertisers, and over 80% contacted known advertising and tracking servers. - Only one of 108 OpenVPN configurations adhered to recommended security practices; 89% used a single authentication method, and nearly 20% employed outdated encryption techniques. - Many apps passed through Play Store checks without adequate scrutiny, with safety labels often serving as marketing tools rather than security indicators. These findings align with previous research highlighting similar issues in popular Android VPN apps. Users are advised to be cautious when selecting VPNs, prioritizing those with recent independent security audits.

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.

Торрент-стриминг без вреда для SSD: переносим TorrServer в Proxmox LXC и интегрируем с Lampa

Modern budget Smart TVs, like the Xiaomi Mi TV, often have limited processing power and memory (1 to 1.5 GB of RAM), which can lead to performance issues when running applications like TorrServer. Users may experience network overloads due to extensive communication with the torrent network, resulting in dropped streams and network failures. Additionally, the RAM shortage can cause the Android system to terminate background services or crash due to Out of Memory errors. CPU throttling occurs as the CPU struggles with torrent processing, leading to overheating and poor playback quality. To address these issues, it is recommended to run TorrServer on a dedicated home server instead of the TV. A lightweight Debian 12 LXC container can be deployed on a Proxmox VE host for this purpose, with the following specifications: VMID 212, hostname torrserver, 2 CPU cores, 2 GB RAM, 512 MB swap, and 8 GB disk space. The container can be created using a specific command on the Proxmox host, and after creation, the TorrServer application can be installed and configured to start automatically.
