Microsoft fixes BitLocker recovery bug on Windows Server 2025

Microsoft has resolved an issue affecting certain Windows Server 2025 devices that were booting into BitLocker recovery mode after the April 2026 security update. This issue was linked to specific BitLocker Group Policy configurations and required users to input their BitLocker recovery key upon the first restart after the update. However, this key would only need to be entered once for subsequent restarts, provided the group policy configuration remained unchanged. The problem primarily affected enterprise systems rather than personal devices. The issue arose under specific conditions: BitLocker was enabled on the operating system drive, a particular Group Policy was set, the Secure Boot State PCR7 Binding was "Not Possible," the Windows UEFI CA 2023 certificate was present, and the device was not already using the 2023-signed Windows Boot Manager. Microsoft released fixes in the KB5094125 and KB5093998 updates to address this problem, preventing devices with incompatible group policy configurations from installing the 2023-signed Windows Boot Manager. Event ID 1032 in the System event log indicates the issue when Windows updates are installed. For IT administrators unable to deploy the latest updates, it is recommended to remove the Group Policy configuration before installing updates or to implement a Known Issue Rollback (KIR) on affected devices. Additionally, Microsoft had previously addressed similar BitLocker recovery issues in August 2024 and May 2025.

NFCShare Android malware spreads via fake banking app updates on GitHub

New variants of the NFCShare Android malware are disguised as fake updates for legitimate banking applications and are targeting customers of various banks in Europe through a phishing campaign to steal sensitive payment card data. The malware prompts victims to place their cards near the NFC chip of their mobile devices, using Android’s IsoDep interface to read card information, including card number, type, expiry date, and a 4-digit PIN. The stolen data is exfiltrated to the attacker’s command-and-control host via a WebSocket channel. Recent attacks began on May 14, with victims directed to a phishing site that impersonates a legitimate bank and then to a GitHub repository hosting a malicious APK file. The repository has hosted 56 unique APKs impersonating banking applications primarily from Italy and Spain. The malware has evolved from initially targeting Deutsche Bank in Germany to a broader range of banks. The latest version features malformed APK packaging to complicate automated analysis. Users are advised to download banking applications only from Google Play and to be cautious of verification requests that ask for NFC card scans.
