Как использование торрентов демаскирует тебя в сети?

When a user downloads or shares a file via torrent, their IP address becomes visible to other participants in the network. The service IKnowWhatYouDownload aggregates this information, allowing users to search by IP address to uncover a list of torrents downloaded or shared from that specific address, along with corresponding dates and times of activity. This service can be used for legal matters, network monitoring, targeted advertising, and RedTeam operations. For example, Yandex Cloud provides a list of public addresses, and a specific IP address (84.252.128.118) was identified as having utilized torrents, allowing for the collection of related statistics on its torrent activity.

Russian Hackers Leverages Weaponized Microsoft KMS to Hack Windows Systems

The Russian state-sponsored hacking group Sandworm, affiliated with the GRU, has been using pirated Microsoft Key Management Service (KMS) activation tools to infiltrate Ukrainian Windows systems since late 2023. They distribute a harmful ZIP file named “KMSAuto++x64_v1.8.4.zip” on torrent platforms, which, when executed, deploys the BACKORDER loader and disables Windows Defender. The BACKORDER loader then downloads the Dark Crystal Remote Access Trojan (DcRAT) from attacker-controlled domains, allowing data theft, including keystrokes and browser credentials. The campaign exploits Ukraine's high prevalence of unlicensed software, estimated at 70% in the public sector, increasing vulnerability to cyberattacks. Researchers have linked this activity to Sandworm through shared infrastructure and tactics, highlighting its role in Russia's hybrid warfare strategy against Ukraine. Cybersecurity experts recommend avoiding pirated software and implementing robust security measures to mitigate these threats.

10 Best UTM (Unified Threat Management) Firewalls

Unified Threat Management (UTM) firewalls integrate multiple security functionalities into a single platform, streamlining security management and reducing costs for organizations, particularly small and medium-sized enterprises (SMEs). UTM solutions include features such as firewalls, intrusion detection and prevention systems (IDPS), antivirus, anti-spam, VPN, web content filtering, and application control, providing comprehensive protection against various cyber threats. UTM firewalls serve as a gateway between internal networks and external connections, inspecting all traffic to block malicious activity. They continuously monitor for suspicious patterns, scan for malware, filter web access, provide VPN capabilities for secure remote connectivity, and filter emails to protect against spam and phishing. UTM systems offer centralized management through a unified dashboard, receive regular updates for emerging threats, and may include performance optimization features. The distinction between UTM and traditional firewalls lies in UTM's broader range of security functions, acting as a comprehensive security solution rather than solely focusing on real-time malware scanning. Top UTM firewalls include: 1. SonicWall UTM: Intrusion prevention and gateway anti-virus. 2. Sophos UTM: User-friendly management with advanced security measures. 3. Check Point UTM: Comprehensive protections including firewalls and VPNs. 4. Fortinet FortiGate UTM: Integrates security and networking functions. 5. WatchGuard UTM: Balances performance, security, and management ease. 6. Juniper UTM: High-performance security services. 7. Barracuda UTM: Extensive network protection through integrated functions. 8. Stormshield UTM: Proactive defense mechanisms. 9. Huawei Unified Security Gateway (USG): Versatile security protections. 10. Cisco UTM: Integrated security and threat management services. Key features of the best UTM firewalls include application control, advanced threat prevention, reporting and analytics, scalability, endpoint protection, and DDoS protection.

How to setup IPAM on Windows Server

IP Address Management (IPAM) in Windows Server automates and centralizes the management of IP address infrastructure, allowing administrators to monitor, manage, and audit DHCP and DNS servers. Setting up IPAM involves several steps: verifying prerequisites (supported Windows Server version, active directory domain, and operational DHCP/DNS roles), installing IPAM through Server Manager or command prompt, configuring IPAM for file sharing and access settings, configuring server discovery, and managing servers and settings. To add an IP address to IPAM, users access the IPAM console, navigate to the IP Address Space section, select the desired IP Address block, and provide necessary details before saving the changes.
