A security researcher has developed a proof-of-concept tool called GhostLock, which exploits a vulnerability in the Windows file API, specifically the 'CreateFileW' function. By manipulating the 'dwShareMode' parameter to grant exclusive access to files, GhostLock can prevent other users or applications from opening those files, resulting in a 'STATUSSHARINGVIOLATION' error. The tool automates the process of opening multiple files on SMB shares, causing access disruptions without requiring elevated privileges. This technique is intended as a disruption attack rather than a destructive one, similar to ransomware, and can serve as a diversion during intrusions. Detection of this attack relies on monitoring the open-file count with ShareAccess set to 0 at the file server layer. Dvash has provided resources for IT teams to enhance detection capabilities against this threat.

This flaw affects devices running Windows 11 and Windows Server 2025 and arises from a weakness in link following. Microsoft released a patch for this issue in November 2025. CISA has added CVE-2025-60710 to its list of actively exploited vulnerabilities and mandated that Federal Civilian Executive Branch agencies secure their systems within two weeks. CISA encourages all organizations, including those in the private sector, to implement necessary patches and improve network security. CISA also advised organizations to follow vendor instructions for mitigations or discontinue use of the affected product if mitigations are unavailable.

On April 3, 2026, Anthropic expanded Claude’s desktop control feature to Windows for Pro and Max subscribers, allowing users to operate applications, navigate web pages, and manage files on their PCs without prior configuration. The feature is in research preview and includes a Dispatch companion for task assignment from mobile devices. Claude uses a structured tool hierarchy for task execution, prioritizing connectors like Slack and Google Calendar, and engages in direct desktop control only when necessary. Users must opt in to activate the feature, which integrates with existing software without requiring API keys. The technology is partly derived from Anthropic’s acquisition of Vercept AI, which specializes in AI-driven computer control. Security concerns have arisen due to vulnerabilities demonstrated shortly after the launch, prompting Anthropic to implement safeguards while acknowledging the feature's potential errors. Users can stop Claude's operations, but the company admits it cannot disable the technology remotely once tasks have started. Competitors like Microsoft and Google are also exploring similar desktop-level AI automation capabilities.

Russian military personnel have been advised to stop using the messaging application Max due to security concerns, as reported by Mediazona. This recommendation follows intensified restrictions on Telegram, which began in the summer of 2025. The Federal Security Service (FSB) has warned that Ukrainian forces can intercept Telegram communications, prompting worries about the safety of sensitive information. Access to Telegram has been increasingly limited, with plans for further restrictions on media file access reported by RBC. Pro-war advocates, including Sergey Mironov, have criticized these limitations and defended Telegram as a reliable communication tool. Despite the Kremlin's claims that troops do not rely on Telegram, the Russian Defense Ministry asserts that they use standard communications equipment and a domestically developed messenger. On February 18, Russian Digital Development Minister Maksut Shadaev stated that Telegram would not be blocked for frontline use for now.

The upcoming Android 17 update is expected to introduce a native App Lock feature, addressing the lack of built-in app locking solutions for Pixel users. Currently, Android's Private Space feature is cumbersome and not user-friendly, leading many to rely on third-party app lockers, which pose security risks. The new App Lock feature, hinted at in the recent Android Canary build, will include an App Lock API requiring specific permissions and will be accessible to all launchers. It aims to provide a more secure and reliable option for locking apps, potentially utilizing the Biometric Prompt API for authentication. However, the feature is not yet active and is unlikely to be released with the upcoming Android 16 quarterly update, with the earliest expectation for availability being with Android 17. Additionally, it remains uncertain how notifications from locked apps will be managed regarding content visibility.
