NordVPN’s CTO on redefining antivirus for the AI era, and his dream security tool

NordVPN has introduced a new offering called "next-gen antivirus" (NGAV) to address evolving cybersecurity threats, particularly those from artificial intelligence. NGAV aims to redefine online security by protecting against sophisticated threats like socially engineered scams and phishing attacks, rather than just traditional viruses. It operates in the background, alerting users to potential scams, blocking ads and trackers, and removing malware without requiring extensive technical knowledge. The company recognizes that personal AI agents present a new cybersecurity challenge and is developing features to protect these agents. NordVPN has incorporated bespoke AI solutions into its NGAV, using efficient models that can identify phishing attempts while running locally on user devices. The company has also shifted to open-weight models to reduce costs while maintaining capabilities, although sensitive areas like payment processing remain unaffected by AI. Despite privacy concerns regarding AI, NordVPN has not faced significant pushback from customers about its AI features and emphasizes its commitment to not using customer data for model training. Briedis warns that over-regulation could hinder innovation in cybersecurity. Looking ahead, he envisions a comprehensive application that monitors users' digital environments and manages their data presence online, while NordVPN plans to focus on creating localized solutions rather than hardware development.
Networking problems after the October 2026 Windows update? NTLM might be to blame

Networking problems after the October 2026 Windows update? NTLM might be to blame

The Windows security update scheduled for October 2026 will block requests using the outdated NTLMv1 security protocol. The BlockNtlmSSO registry value governs this change; if unset, Windows will default to Enforce mode, blocking NTLMv1-derived credentials. Administrators can temporarily set this value to 0 to allow NTLMv1, but Microsoft warns this reduces security. The deprecation of NTLM was first announced in 2024, with audit logs for NTLMv1 usage introduced in August 2025. NTLM was first introduced in 1993, and while it has been removed from Windows 11 24H2 and Windows Server 2025, traces remain in certain configurations. Credential Guard must be enabled, and the BlockNtlmSSO value must not be set to Audit mode for NTLMv1-derived credentials to be allowed. Microsoft aims to eliminate NTLM entirely, and the upcoming update signals the need for organizations to accelerate their transition away from NTLMv1.

VPN threat protection vs. dedicated antivirus: Are VPNs really enough?

Many VPN providers are now offering additional security features such as malware detection, malicious link checkers, and ad blockers, alongside their primary function of encrypting internet traffic. Notable VPNs like NordVPN and Surfshark have integrated real-time malware protection, with NordVPN becoming the first VPN to receive certification as a reliable anti-phishing tool in 2024. Surfshark's Surfshark One package offers comprehensive real-time protection from viruses and malware. Other VPNs, such as Avira and CyberGhost, utilize shared infrastructures for antivirus capabilities, which can lead to delays in updates and inconsistent platform support. Microsoft Defender has improved significantly, blocking 95.5% of live threats according to AV-Comparatives, while Apple employs multiple defenses in macOS, including Gatekeeper and XProtect, to manage malware threats. Avast Free Antivirus has achieved a perfect 100% block rate in recent testing but comes with limitations compared to paid antivirus suites like Norton 360 Deluxe and Bitdefender Total Security, which offer additional features such as password managers and identity monitoring. A layered approach to digital security, combining a VPN, free antivirus, and built-in OS-level security, is recommended for effective protection. Relying solely on one layer leaves potential gaps, as a VPN cannot detect existing malware, and free antivirus solutions may lack advanced features. Users managing sensitive data or frequent financial transactions should consider investing in premium antivirus suites for enhanced security.

India Orders Apple to Pull Jack Dorsey’s Offline Messaging App Bitchat

Apple has removed the decentralized messaging application Bitchat, developed by Twitter co-founder Jack Dorsey, from its App Store in India following a directive from the Indian federal government under Section 69A of the Information Technology Act, citing national security. The notice from Apple's App Review team, shared by Dorsey on October 3, 2026, did not specify the illegal content. The app remains available in other regions, but users in India will lose access to TestFlight testing and public beta links. This action follows a previous request made on July 23, 2026, by the Indian Cyber Crime Coordination Centre to GitHub to disable access to three Bitchat repositories, invoking Section 79(3)(b) and Rule 3(1)(d). The Internet Freedom Foundation has contested the July order, claiming authorities bypassed established blocking frameworks. Bitchat, introduced as open-source software in July 2025, allows local Bluetooth mesh communication and internet messaging without relying on a central server, raising concerns for law enforcement. The timing of the restrictions coincided with youth-led protests in India, which led to a significant increase in Bitchat downloads, accounting for about 85% of the app's global downloads during a protest period from July 17-23. Despite the removal, existing installations can still communicate locally without needing app store access. Previously, in May 2023, India invoked Section 69A against other messaging applications, and China also mandated Bitchat's removal in April 2026 for similar reasons. Digital rights advocates argue the government's justification for the ban is concerning as it sets a precedent for restricting software based on technical capabilities.

Microsoft warns fake CAPTCHA tests are hijacking Windows PCs

Microsoft has warned Windows users about a cyber threat that disguises itself as a CAPTCHA test, where cybercriminals use fraudulent verification pages to trick users into executing commands that can install malware. This tactic involves users being directed to a compromised website that presents a fake verification window, prompting them to copy text and execute it in the Windows Run dialog. This method allows attackers to bypass antivirus software by pre-loading malicious scripts disguised as harmless images in the browser's cache. Once activated, the malware collects system information, steals data, and maintains long-term control over the system. Microsoft recommends using robust security software and being aware that no legitimate service will ask users to copy and paste commands into system dialogs.

Apple removes messaging app used by protesters to bypass internet restrictions in India

Apple removed the offline messaging application Bitchat from its India App Store following a request from the Ministry of Information Technology. This decision was influenced by reports that demonstrators at Jantar Mantar used Bitchat to communicate during protests against alleged irregularities in competitive examinations amid internet restrictions. Bitchat is an open-source, decentralized messaging app that allows communication without mobile data or Wi-Fi, using Bluetooth Low Energy technology and ensuring privacy through end-to-end encryption. The app's removal halts new downloads and security updates, although it remains accessible on existing devices. The Ministry of Electronics and Information Technology invoked Section 69A of the Information Technology Act, 2000, to facilitate the takedown, citing national security and public order. The Internet Freedom Foundation criticized the removal as unconstitutional, arguing it infringes on free speech rights and called for transparency regarding the blocking order and rationale behind the action.

How Two Android Intent Bugs Broke My App’s Red Alert Button

An Android application named CareVocal (internally referred to as CareBridge) was developed to facilitate communication for the user's mother living in a village. The app features three buttons: green for "feeling good," yellow for "something hurts," and red for "need help." Tapping the red button triggers three actions: saving an entry for her doctor, generating a pre-filled SMS to trusted contacts, and opening the phone dialer with the local emergency number pre-typed. The app requires the user to confirm sending the SMS and calling the emergency number to comply with Google Play's restrictions. During testing, issues arose where the SMS draft would not appear if the dialer was opened first, leading to adjustments in the code. A method was implemented to launch multiple intents simultaneously, ensuring that the SMS draft and dialer could be accessed without conflicts. Additionally, the recording feature was modified to start only after a second tap on the red button, separating it from the alert process to avoid distractions during emergencies. The app does not collect location data and is designed solely for logging and communication without diagnostic capabilities.
