Emotet: The horse returns to a gallop more dangerous than ever

Emotet is a Trojan Horse malware that emerged in 2014, impacting over 1.6 million devices and originally designed to steal banking credentials. Developed by the MealyBug criminal organization, it evolved into a modular Trojan-dropper, enabling it to download various payloads and act as Malware-as-a-Service on the dark web. Emotet spreads primarily through spam emails, often using malicious Word or Excel files, and has been disseminated via local area networks and password-protected zip folders. The malware operates through botnets categorized into epochs, with Epochs 1, 2, and 3 dismantled in 2021 by a coordinated international operation. Following this, Emotet resurfaced in November 2021 as Epochs 4 and 5, incorporating a Cobalt Strike beacon for enhanced propagation. Recommended precautions include keeping software updated, using two-factor authentication, and educating employees about email threats. Network administrators are advised to block unscannable email attachments, configure specific email filters, and maintain secure backups.

How to configure multiple DHCP scopes on one Windows server

Administrators use the Dynamic Host Configuration Protocol (DHCP) service to manage IP address configurations for clients efficiently. Deploying multiple DHCP scopes on a single server is more practical than having separate servers for each subnet. DHCP operates through a four-step lease process: discover, offer, request, and acknowledge. To install a DHCP server, the PowerShell cmdlet Install-WindowsFeature DHCP -IncludeManagementTools is used, and the server must be authorized in Active Directory. A single DHCP server can manage multiple scopes, each with specific configurations for different subnets, such as DevNet, ProdNet, SalesNet, and EngineersNet. Each scope can have unique IP address ranges and settings, and additional scopes can be created by adding network interface cards (NICs) to the server. Server options apply globally, while scope options are specific to individual scopes. Reserved IP addresses can also be configured within each scope.

Microsoft broke DHCP for Windows Server last Patch Tuesday

Microsoft has acknowledged that the updates released on June 10 during Patch Tuesday may disrupt the Dynamic Host Configuration Protocol (DHCP) service on Windows Server versions 2025, 2022, 2019, and 2016. The DHCP Server service might intermittently stop responding after installing this security update, causing issues for network administrators as clients may be unable to renew their IP addresses. There is currently no viable workaround for affected users other than rolling back the patch, which is not ideal due to the critical security fixes included in the update. The impact of this issue varies among users, with some experiencing significant problems while others report no disruptions. Microsoft is working on a resolution and will provide further information soon. Additionally, Microsoft has faced challenges with its Surface Hub v1 devices, requiring an out-of-band update.

Windows Server update may disrupt IP refreshes

Microsoft has acknowledged that the June security update has caused complications for users of Windows Server systems, specifically affecting the Dynamic Host Configuration Protocol (DHCP) service, which is failing and leading to improper functioning of IP refreshes. The issue impacts multiple versions of Windows Server, including 2016 (KB5061010), 2019 (KB5060531), 2022 (KB5060526), and 2025 (KB5060842). Users have reported that the DHCP service may stop responding after installing the update, with one administrator noting their 2016 server crashed shortly after the update was applied. Microsoft is working on a solution and advises affected users to uninstall the update to restore functionality. The company has a history of DHCP-related issues dating back over a decade and has faced other problems with Windows Server updates in the past year, including issues with keyboard and mouse inputs and authentication challenges.

Microsoft Resolves Windows Server 2025 Restart Bug Disrupting Active Directory Connectivity

Microsoft released updates in June 2025 to address critical issues affecting Windows Server 2025 domain controllers, specifically authentication failures and network connectivity problems. The updates, encapsulated in KB5060842, resolved issues stemming from security update KB5055523, which altered certificate validation methods for Kerberos authentication. This change led to logging errors for self-signed certificates and affected Windows Hello for Business Key Trust deployments. Additionally, a separate issue prevented domain controllers from managing network traffic correctly after restarts, causing them to revert to standard firewall profiles. Microsoft provided a temporary workaround for administrators to manually restart network adapters until a permanent fix was implemented. The June updates addressed a total of 66 vulnerabilities, including 10 rated as Critical, and recommended immediate installation. Microsoft advised against setting the AllowNtAuthPolicyBypass registry key to ‘2’ for domain controllers using self-signed certificates until the latest updates were applied.

5 reasons I regret not deploying my own home firewall sooner

A hardware firewall enhances network security by monitoring and filtering all traffic, preventing unauthorized access based on pre-defined rules, and analyzing traffic patterns for anomalies. It employs Next-Generation Firewall technology for deep packet inspection, utilizes GeoIP restrictions, and runs Intrusion Prevention/Detection Systems (IPS/IDS). Implementing a Zero Trust architecture minimizes device access, and notifications alert users to new device connections. Segregating IoT devices onto a dedicated VLAN reduces security risks. A multi-layered security approach, including rules-based and deep packet inspection, is essential for comprehensive protection. Hardware firewalls often run on Linux or FreeBSD, allowing additional functionalities like ad blocking through services such as Pi-hole. Cataloging devices improves troubleshooting and network management. The adoption of hardware firewalls is increasingly necessary due to the rise of connected devices in homes.

5 reasons you should use PowerShell even if you don’t use Windows

PowerShell is a command-line interface that operates across Windows, Linux, and macOS, designed for automation and system management. It utilizes the Common Language Runtime (CLR) from the .NET framework, allowing it to function on any OS with CLR support. PowerShell automates repetitive tasks, enhancing productivity in file management, data processing, and system administration. It provides a familiar interface for system administrators managing mixed environments, facilitating effective cross-platform network management. PowerShell is compatible with Microsoft services like Azure, AWS, VMware, Exchange, and Active Directory, and can execute certain Linux commands natively. Since becoming open-source under the MIT license, it has encouraged community contributions and adaptation for modern IT environments. PowerShell differs from Windows PowerShell by offering cross-platform functionality and regular updates, making it a versatile tool for managing systems and services across various operating systems.

How to install and deploy Network Controller on Windows Server

The Network Controller in Windows Server is a server role that enables centralized management of physical and virtual network infrastructures. To install and deploy a Network Controller, the following steps are required: 1. Create a Security Group: Establish an Active Directory Domain Services (AD DS) Security Group by creating a new group in Active Directory User and Computer, adding necessary users, and requesting a certificate from a Certificate Authority. 2. Install the Network Controller: Open Server Manager, navigate to Add Roles and Features, select the Network Controller role, and complete the installation process. 3. Deploy Network Controller: Configure the Network Controller cluster by creating a cluster node using PowerShell commands, specifying parameters such as the node name, server FQDN, fault domain, and REST interface. Then, run a command to configure the cluster with options for authentication, management security group, log locations, and SSL usage. Finally, validate the deployment by executing the command Get-NetworkController.
