Norton (durch Symantec Übernahme teilweise verknüpft, aber Marke liegt bei Gen Digital. Broadcom i

Norton, owned by Gen Digital, provides antivirus software, VPN services, and identity theft monitoring to protect users from cyber threats such as malware and phishing attacks. The company emphasizes subscription-based revenue through Norton 360, which bundles various security features, ensuring predictable cash flow. Norton competes with other antivirus brands like McAfee and Bitdefender, maintaining a strong market share in North America due to its established brand trust. The demand for cybersecurity tools is driven by rising cyber threats, including ransomware attacks and increased remote work, which necessitate robust online protection. Gen Digital is investing in AI-driven threat detection and expanding its offerings to address evolving security needs. However, Norton faces challenges from free alternatives, potential privacy concerns, and macroeconomic pressures that could affect consumer spending on security products.

Privacy Messenger Session Is Staring Down a 90-Day Countdown to Obscurity

The messaging app Session, which prioritizes user privacy and offers end-to-end encryption without requiring personal information for registration, is facing potential closure and has issued a call for support. The Session Technology Foundation (STF) has received funding to support operations for 90 days but will rely on volunteers after all paid staff have been let go. Development activities have paused due to insufficient funding, affecting the introduction of new features and the resolution of existing bugs. The STF has stated that it needs million to complete ongoing projects and introduce a subscription model to achieve self-sustainability. As of now, 0,000 has been raised towards this goal. Users can contribute at getsession.org/donate.

Microsoft Introduces Phishing-Resistant Windows Sign-Ins With Entra Passkeys

Microsoft will introduce phishing-resistant passwordless authentication through passkeys for Windows devices, integrated with Microsoft Entra. This feature is expected to enter public preview between mid-March and late April 2026 for global tenants, while government cloud environments will receive the update from mid-April to mid-May. Users can access Entra-protected resources using device-bound passkeys stored securely within Windows Hello, allowing authentication through biometric or local verification methods. This update expands passwordless authentication to unmanaged or personal Windows devices. Passkeys utilize public-key cryptography, enhancing security by storing a private key on the device and registering a matching public key with the service. Each passkey is uniquely associated with a specific device and cannot be exported or synchronized. Organizations must enable the Passkeys (FIDO2) authentication method in Entra for the preview. This initiative is part of Microsoft's broader strategy to eliminate passwords, responding to rising cybersecurity concerns related to password-based authentication.

Quantum Computing Isn’t Just Coming for Bitcoin—It Threatens Messaging Apps Too

IBM researchers are collaborating with Signal and Threema to develop messaging systems resilient to quantum computing threats, prompted by concerns that quantum technology could compromise current encryption methods. IBM's report stresses the need to redesign messaging protocols in anticipation of potential quantum capabilities that could break existing encryption. Cryptography expert Ethan Heilman highlighted that encrypted messaging platforms face immediate risks from quantum threats, specifically through "store-and-forward attacks." Both Signal and Threema are enhancing their security measures; Signal is implementing upgrades like PQXDH and SPQR for post-quantum protection, while Threema is integrating the ML-KEM algorithm for quantum-safe encryption. Research indicated that adapting the Signal protocol for quantum safety may increase bandwidth requirements, necessitating a complete redesign for efficiency.

Messenger can warn you about sketchy links without knowing what you clicked

Meta has introduced Advanced Browsing Protection (ABP) in its Messenger application to enhance user safety by identifying harmful websites during chats. ABP utilizes a constantly updated watchlist of potentially harmful websites, improving upon the existing Safe Browsing feature. Due to end-to-end encryption, Messenger cannot access message content or links, so ABP uses cryptography and secure computing techniques for link verification without exposing them. When a user clicks a link, Messenger checks it against a blocklist using a privacy-preserving query system. Users can enable or disable ABP in the Messenger app under Settings, Privacy & safety, and Safe browsing. If the option is not visible, users may need to update the app.

Microsoft to disable NTLM by default in future Windows releases

Microsoft will disable the NTLM authentication protocol by default in the next major Windows Server release and associated Windows client versions. NTLM, introduced in 1993, has been vulnerable to various cyberattacks, including NTLM relay and pass-the-hash attacks. The transition plan includes three phases: enhanced auditing tools in Windows 11 24H2 and Windows Server 2025, new features like IAKerb and a Local Key Distribution Center in late 2026, and eventually disabling network NTLM by default in future releases. NTLM will remain in the operating system but will not be used automatically. Microsoft deprecated NTLM authentication in July 2024 and has encouraged developers to transition to Kerberos or Negotiation authentication.
