Claude, an AI tool developed by Anthropic, receives nearly 290 million web visits monthly and has become a target for cybercriminals. A fake website has been found that impersonates Claude, distributing a trojanized installer named Claude-Pro-windows-x64.zip. This installer, while appearing legitimate, deploys PlugX malware, granting attackers remote access to users' systems. The fraudulent site mimics the official download page and uses passive DNS records linked to commercial bulk-email platforms, indicating active maintenance by the operators. The ZIP file contains an MSI installer that incorrectly spells "Claude" as "Cluade" and creates a desktop shortcut that launches a VBScript dropper. This script runs the legitimate claude.exe while executing malicious activities in the background, including copying files to the Windows Startup folder to ensure persistence after reboot. The attack utilizes a DLL sideloading technique recognized by MITRE as T1574.002, where a legitimate G DATA antivirus updater is exploited with a malicious DLL. Within 22 seconds of execution, the malware establishes a connection to an IP address associated with Alibaba Cloud, indicating control over the compromised system. The dropper script also employs anti-forensic measures to delete itself and the VBScript after deployment. Indicators of compromise include the filenames Claude-Pro-windows-x64.zip, NOVUpdate.exe, avk.dll, and NOVUpdate.exe.dat, along with the network indicator 8.217.190.58:443 (TCP) as the command and control destination. Users are advised to download Claude only from the official site and to remain vigilant against potential compromises.

Avast launched its VPN service, Avast Secureline VPN, in 2017, focusing on encryption, a no-logs policy, and DNS leak protection. The company operates outside the 5, 9, or 14 Eyes alliances, which limits data-sharing with intelligence agencies. In January 2020, Avast faced criticism for collecting user data for its subsidiary, Jumpshot, but ceased this practice shortly after. The VPN offers dedicated servers for streaming and torrenting, basic split tunneling, and a kill switch, but lacks comprehensive features compared to competitors. Supported protocols include WireGuard, OpenVPN, and IPsec, with encryption standards generally secure. Avast claims to operate 700 servers across 27 countries, with a limited selection of streaming-optimized servers. The app supports various platforms but lacks support for Linux or routers. Speed tests showed an average download speed of 275.69 Mbps, but performance in unblocking content was disappointing, with limited success on streaming services. Avast's privacy policy indicates extensive data collection, despite claims of addressing past issues. Customer support includes 24/7 access for paying customers. Pricing tiers include a 60-day free trial, with competitive rates but limited features. Pros include decent speeds and reasonable pricing, while cons highlight controversial data practices, limited information, poor streaming performance, and fewer features compared to competitors.

A critical bug in Windows 11 builds 24H2 and 25H2 is causing users with Ethernet connections to lose internet access after installing updates KB5066835 and KB5065789. Users have reported issues on Microsoft’s Q&A forums, and rolling back the operating system is recommended. Possible fixes include performing a full network reset, flushing DNS and resetting TCP/IP via Command Prompt, editing the registry, and using hardware bypass solutions like USB-to-Ethernet or USB-to-WiFi adapters.

Cybercriminals are exploiting a legacy feature in Windows File Explorer, specifically the WebDAV protocol, to distribute malware and bypass traditional security measures. Despite Microsoft deprecating native WebDAV support in November 2023, it remains active on many systems. Attackers use WebDAV to deceive victims into executing malicious payloads by sending links that connect File Explorer directly to remote servers, avoiding web browsers and their security warnings. They employ methods such as direct linking, URL shortcut files, and LNK shortcut files to deliver exploits. The primary objective of these campaigns, which surged in late 2024, is to deploy Remote Access Trojans (RATs), with 87% of Active Threat Reports involving multiple RATs like XWorm RAT, Async RAT, and DcRAT. These campaigns predominantly target corporate networks in Europe, with many phishing emails written in German and English. Attackers use short-lived WebDAV servers hosted on Cloudflare Tunnel demo accounts to obscure their infrastructure. Security analysts are advised to monitor unusual network activity from Windows Explorer and educate users to verify addresses in File Explorer.

Russian authorities have been implementing a "sovereign Internet" initiative, which involves controlling digital communication and filtering information accessed by citizens. Recently, on February 11, Roskomnadzor removed WhatsApp from the National Domain Name System, effectively erasing it from the Russian digital landscape, which impacts over 100 million users. Two days earlier, Telegram experienced significant slowdowns, leading to fines for alleged non-compliance with Russian law. The government has been promoting the state-controlled messaging app, Messenger Max, developed by VK, as an alternative to popular platforms like WhatsApp and Telegram. The recent removal of 13 domain names, including those of major news outlets, marks a significant escalation in efforts to control digital information and is part of a broader strategy established since 2019 to impose stringent Internet regulations. This includes the establishment of a Russian National Domain System that allows Roskomnadzor to dictate website accessibility within the country, raising concerns about the potential instability and isolation of the Russian Internet.

Russia's internet regulator, Roskomnadzor, has made YouTube inaccessible in the country by removing its domain from the National Domain Name System (NDNS) servers, which prevents direct access without a VPN. YouTube is now blocked along with WhatsApp, as part of a broader crackdown on digital communication tools. The NDNS serves as a government-mandated alternative directory that restricts telecommunications providers to using it exclusively, allowing centralized control over website accessibility. Roskomnadzor has removed 13 domain names from NDNS, including those of international news outlets and social media platforms. A survey indicates that 46% of Russian users utilize VPNs to access YouTube, but 24% still experience connectivity issues. Users report frustration with internet access quality and potential repercussions from government legislation against searching for "extremist material" or using VPNs. Experts warn that reliance on NDNS could limit normal DNS functionality and highlight risks associated with VPN use, including government manipulation of IP addresses. Roskomnadzor cites violations of Russian law to justify its control over platforms like Telegram.

U.S. law enforcement, in collaboration with Bulgarian authorities, has seized the domains zamunda.net, arenabg.com, and zelka.org due to copyright infringement related to pirated content. This operation was authorized by a U.S. District Court ruling and coordinated by the U.S. Department of Homeland Security, Europol, and Bulgarian officials. The domains, which were managed by U.S.-based registrars, have been redirected to U.S. control, displaying an official seizure notice. A significant portion of the content on these sites is owned by American companies, allowing U.S. jurisdiction. Bulgaria has been working to combat piracy since at least 2020 and was recently placed back on the U.S. Trade Representative's "Special 301 Report" list for insufficient progress. The servers hosting the trackers may be located outside Bulgaria, complicating their seizure. This operation highlights the risks faced by piracy platforms linked to international domains.
