Minecraft Players Targeted by LofyStealer Using Node.js Loader and In-Memory Browser Injection

A new infostealer malware called LofyStealer is targeting the gaming community, particularly Minecraft players, by disguising itself as a cheat tool named “Slinky.” It employs a two-stage attack to extract sensitive information from eight major web browsers, including Chrome and Firefox, while evading detection by security software. The malware siphons off cookies, saved passwords, payment card information, and session tokens. Researchers at Zenox.ai identified LofyStealer, linking it to the Brazilian cybercrime group LofyGang, which has been active since October 2022. The malware uses social engineering tactics to appear legitimate and operates as a Malware-as-a-Service platform, offering both Free and Premium tiers to buyers. Its technical sophistication is evident in its method of in-memory browser injection, which allows it to bypass security defenses. The stolen data is compressed and sent to a command-and-control server. Users are advised to avoid downloading unofficial game mods and enable multi-factor authentication to reduce the risk of credential theft. Security teams should monitor for specific behavioral indicators related to the malware's operations.

Emergency Update for Windows Server Following Reboot Issues

Microsoft has released emergency updates for various versions of Windows Server due to issues arising from the April 2026 Patch Tuesday security updates. A significant problem was a reboot loop affecting domain controllers caused by crashes of the Local Security Authority Subsystem Service (LSASS), which disrupted authentication services. This issue was especially problematic during the setup of new domain controllers. Additionally, some Windows Server 2025 systems encountered difficulties in installing the security update KB5082063. The out-of-band update (KB5091157) for Windows Server 2025 addresses both the installation failure and the domain controller restart issue. Other updates targeting the domain controller restart problem were released for additional supported Windows Server versions. Microsoft has introduced an out-of-band update for seven versions, including KB5091157 for Windows Server 2025 and KB5091571 for Windows Server, version 23H2. Furthermore, some Windows Server 2025 devices may boot into BitLocker recovery mode after the update, requiring users to enter a BitLocker recovery key.

Risks of Manual PostgreSQL Starts in Patroni Clusters: Downtime Warnings

Patroni is an open-source tool for managing PostgreSQL clusters, automating failover and replication. Manual starting of PostgreSQL services within an active Patroni cluster can lead to severe disruptions, including data integrity issues and availability risks. Patroni uses a distributed consensus system, often with etcd or Consul, to manage cluster state and leader elections. Manual interventions can confuse this process, resulting in multiple nodes believing they are the primary, which can cause conflicting writes and potential data loss. Real-world incidents have documented outages due to manual starts, such as promoting a replica node to leader status inadvertently. This disrupts Write-Ahead Logging (WAL) synchronization, leading to divergent transaction logs. Database administrators are advised to use Patroni's built-in commands for service management and implement role-based access controls to prevent unauthorized manual actions. Monitoring solutions are crucial for early detection of anomalies. Simulating failure scenarios in staging environments can help prepare teams for real incidents. Ongoing advancements aim to enhance Patroni's safeguards against manual overrides, with future iterations potentially incorporating AI-driven anomaly detection.

Microsoft: Windows Server hotpatching to require subscription

Microsoft will transition hotpatching for Windows Server 2025 to a paid subscription model starting July 1, 2025, with a cost of [openai_gpt model="gpt-4o-mini" prompt="Summarize the content and extract only the fact described in the text bellow. The summary shall NOT include a title, introduction and conclusion. Text: Microsoft has made a significant announcement regarding the future of hotpatching for Windows Server 2025, a feature that allows administrators to apply security updates without the need for system restarts. As the company prepares for the general availability of this service, it will transition to a paid subscription model starting July 1, 2025. Subscription Details and Preview Phase In a proactive move, Microsoft is encouraging administrators to take advantage of the free preview of hotpatching before it becomes a subscription-based service. This opportunity will remain available until June 30, after which those currently testing the service will be automatically subscribed unless they opt out. “Hotpatching for Windows Server 2025, made available in preview in 2024, will become generally available as a subscription service on July 1st, 2025. With hotpatching, we are taking what was previously an Azure-only capability and now making it available to Windows Server machines outside of Azure through Azure Arc,” Microsoft stated. Upon the subscription launch, hotpatching will be priced at .50 USD per CPU core per month. To utilize this feature in multi-cloud environments or on-premises, users will need both a Hotpatch service subscription and an Azure Arc-connected server running Windows Server 2025 Standard or Datacenter. How to Enable Hotpatching Enabling hotpatching on your server is a straightforward process. First, connect your server to Azure Arc by following the specified steps. Next, navigate to Azure Update Manager within the Azure Portal, select your Azure Arc-enabled server, and check the hotpatching option as outlined in the provided documentation. A Brief History of Hotpatching Hotpatching has been a part of Microsoft's offerings since February 2022, initially available for Windows Server 2022 Datacenter: Azure Edition. This feature allows for the deployment of security updates by patching the in-memory code of running processes, eliminating the need for reboots after each installation. However, it is important to note that servers still require reboots for updates delivered through the standard Windows update channel, which are not included in the Hotpatch program. This includes non-Windows updates, such as .NET patches, and Windows non-security updates. Microsoft began public testing of hotpatching for Windows Server 2025 in September 2024, with further expansions to Windows 11 24H2 and Windows 365 following in November 2024. By April 2025, hotpatch updates will be generally available for business customers using Windows 11 Enterprise 24H2 on x64 (AMD/Intel) systems." max_tokens="3500" temperature="0.3" top_p="1.0" best_of="1" presence_penalty="0.1" frequency_penalty="frequency_penalty"].50 per CPU core per month.

Microsoft teases pay-to-patch plan for Windows Server 2025

Microsoft plans to transition its hotpatching feature for on-premises Windows Server 2025 into a paid subscription service starting in July, priced at [openai_gpt model="gpt-4o-mini" prompt="Summarize the content and extract only the fact described in the text bellow. The summary shall NOT include a title, introduction and conclusion. Text: Microsoft has unveiled plans to transition its hotpatching feature for on-premises Windows Server 2025 into a paid subscription service starting in July. This innovative capability allows administrators to implement software updates without the need for system reboots, a significant advantage that streamlines the update process. Hotpatching: A Game Changer for Administrators Hotpatching is not a novel concept; it has been a staple in various environments, including the Linux kernel, VMware products, and the Xen hypervisor. The primary appeal lies in its ability to facilitate security updates without the disruption of reboots, enabling IT teams to maintain operational continuity without the hassle of scheduling downtime. This feature will be a game changer; you may finally get to see your family on the weekends. Currently, Microsoft offers hotpatching for its Windows Server: Azure Edition and version 2022 within its Azure cloud infrastructure. The company has highlighted that its Xbox team has been a significant user of this feature. In August 2024, a preview of hotpatching for Windows Server 2025 running in Azure was announced, followed by a subsequent preview for on-premises implementations managed through the Arc hybrid-and-multicloud management tool. With this latest update, hotpatching is now available for both the Standard and Datacenter editions of Windows Server 2025, allowing on-premises users to benefit from this functionality. Hari Pulapaka, Microsoft’s general manager of Windows Server, emphasized the transformative potential of hotpatching, noting, “This feature will be a game changer; simpler change control, shorter patch windows, easier orchestration.” He humorously added that it might even allow professionals to enjoy more time with their families on weekends. As of last Thursday, Microsoft announced that the current preview will conclude on June 30, transitioning into a subscription model priced at .50 per core per month. Traditional non-hotpatch updates will remain available at no cost. In a detailed explanation, Janine Patrick, Windows Server Product Marketing Manager, and Artem Pronichkin, Senior Program Manager, outlined the service's structure, which aims to deliver eight hotpatches annually. This schedule follows a three-month cycle: the first month serves as a baseline month (monthly cumulative update), followed by two months dedicated to hotpatches. During baseline months—January, April, July, and October—reboots will be necessary. They also noted that, on rare occasions, a non-hotpatch update may be required during a hotpatch month for security reasons, which would also necessitate a reboot. However, the goal remains to provide up to eight hotpatches each year. The benefits of hotpatching are clear, as it can significantly reduce the 'window of vulnerability' that often occurs when administrators delay updates and restarts following a Windows security update. Additionally, it alleviates the traditional burdens associated with 'Patch Tuesday' updates. Importantly, adoption of hotpatching remains optional; Microsoft will continue to provide software updates according to its existing schedule. However, the company anticipates that many Windows Server 2025 users will find value in the ability to minimize downtime through this subscription service. While Windows Server 2025 machines will need to be managed by Arc to utilize hotpatching, there will be no additional costs associated with using Arc for this new offering. Users currently testing the hotpatching preview will automatically transition to the subscription model starting July 1, unless they choose to disenroll before June 30. Notably, Azure Editions of Windows Server will continue to receive hotpatching at no charge. As this new subscription service approaches, the question remains: Will users embrace the opportunity to pay for the promise of non-disruptive patches?

Starting July 1, 2025, there will be a charge of [openai_gpt model="gpt-4o-mini" prompt="Summarize the content and extract only the fact described in the text bellow. The summary shall NOT include a title, introduction and conclusion. Text: In the realm of operating systems, security updates are paramount, especially when they pertain to software utilized by billions globally. However, Microsoft has recently found itself in a challenging spotlight following a controversial Windows security patch that inadvertently introduced a mysterious folder, sparking a wave of confusion and concern among users. Social media commentators hastily advised users to delete this folder, only for Microsoft to counter with a warning that such actions could leave systems vulnerable to attacks. This incident has now unveiled a broader issue within the Windows security update framework, particularly surrounding the introduction of a subscription model for no-reboot security “hotpatch” updates. What Is Windows Hotpatching, And Who Needs To Pay The .50 A Month Fee? As previously reported, Microsoft is advancing towards a system where hotpatching will eliminate the need for users to reboot their Windows systems after a security update. This innovative feature allows security fixes to be downloaded and installed seamlessly in the background, integrating directly into the in-memory code of processes that are already running. Initially, this functionality is set to be available for a specific segment of users: those operating Windows 11 Enterprise, version 24H2, on x64 (AMD/Intel) CPU devices managed through Microsoft Intune. Recent confirmations from Janine Patrick, Windows Server product marketing manager, and Artem Pronichkin, a senior program manager at Microsoft, indicate that the hotpatching system for Windows Server 2025, which has been in preview since 2024, will transition to a subscription-only model starting July 1. To utilize the no-reboot hotpatch security updates, users must operate on “Windows Server 2025 Standard or Datacenter,” with an essential requirement of being connected to Azure Arc.

Microsoft to Launch Paid Hotpatching for Windows Server 2025

Microsoft will launch a subscription-based hotpatching service for Windows Server 2025 on July 1, 2025, priced at [openai_gpt model="gpt-4o-mini" prompt="Summarize the content and extract only the fact described in the text bellow. The summary shall NOT include a title, introduction and conclusion. Text: Microsoft is set to transform the landscape of enterprise updates with the upcoming launch of its subscription-based hotpatching service for Windows Server 2025. This innovative approach marks a significant shift in how updates will be managed for businesses operating Windows Server outside of Azure. Beginning July 1, 2025, hotpatching will transition from a complimentary preview to a paid subscription model, priced at .50 per CPU core per month. This change extends a capability that was previously exclusive to Azure users, now making it accessible for on-premises servers and hybrid environments through Azure Arc integration. What Is Hotpatching? Hotpatching is a cutting-edge technology that enables the installation of security and critical updates without necessitating a system reboot. Instead of interrupting services or rebooting servers, hotpatching directly updates the in-memory code of running processes. This advancement brings Windows server deployments in line with similar technologies that Linux administrators have enjoyed for years, such as kpatch and ksplice. By allowing updates without reboots, organizations can significantly reduce disruptions while enhancing their security posture. How Does Hotpatching Work? The hotpatching mechanism follows a structured update cycle: Baseline months: In January, April, July, and October, a full cumulative update will be released, requiring a reboot to establish a new baseline. Hotpatch months: In the two months following each baseline month, critical patches will be deployed via hotpatches without requiring any server reboots. This means that servers will only need to reboot approximately four times a year, rather than monthly. On rare occasions, Microsoft may issue a critical security update that requires a reboot even during a hotpatch month, but the aim remains clear: to provide up to eight rebootless hotpatches annually. Why Is Microsoft Moving to a Paid Model? While hotpatching was available at no additional cost during its preview phase, Microsoft is now positioning it as a premium feature for customers seeking maximum uptime, operational simplicity, and rapid security response. According to the Windows Server team at Microsoft, the value of hotpatching encompasses: Reduced Downtime: Maintain operations without the need for scheduling late-night or weekend reboot windows. Faster Updates: Smaller patches facilitate quicker deployments. Enhanced Security: Address vulnerabilities swiftly without delays associated with reboot coordination. Operational Efficiency: Streamlined change management and patch orchestration. Internal teams at Microsoft, including the Xbox division, have already experienced notable efficiency improvements with hotpatching, completing tasks that previously took weeks in just days.
