Microsoft's built-in security tool in Windows 11 is considered sufficient for most users, but a recent issue has emerged where certain PCs are unable to complete security scans, potentially exposing them to vulnerabilities. Users on Reddit reported problems with Microsoft Defender, specifically with both Full Scan and Quick Scan functionalities failing. One user noted that a recent update may have caused the tool to crash shortly after scans begin, with offline scans stopping at 90-93% completion. The issue may be linked to a Microsoft Security Intelligence update, and some users have found that upgrading to Security Intelligence Update v1.457.236.0 resolved the problem for them.

A new variant of the NGate Android malware exploits a legitimate NFC payment app, HandyPay, to steal users' card information and PINs, enabling unauthorized contactless transactions. This malicious version of HandyPay, which has been available since 2021, was identified by ESET researchers and is distributed through a fraudulent lottery website and a fake Google Play page. The malware captures sensitive information by prompting users to enter their payment card PIN and tap their card against the device, sending the data to an attacker-controlled phone and exfiltrating the PIN to a command-and-control server. The campaign employs social engineering tactics and requires minimal permissions, relying on users to enable app installations from unknown sources. The attackers use a centralized infrastructure for malware distribution and PIN collection, with evidence of compromised devices in Brazil. The shift to modifying a legitimate application is motivated by financial incentives, as it offers similar functionality at a lower cost compared to underground tools. Users are advised to avoid installing apps from unofficial sources and to ensure the legitimacy of applications before entering sensitive information.

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.
