Support for Windows Server 2016 is coming to an end

Microsoft has announced the end of support for several Windows products launched in 2016, including Windows Server 2016, Windows 10 Enterprise 2016 LTSB, and Windows IoT Enterprise LTSB 2016. Windows Server 2016 has been in the extended support phase since January 2022, with security updates available until January 12, 2027. Windows 10 Enterprise 2016 LTSB and Windows IoT Enterprise LTSB 2016 will reach the end of their extended support on October 13, 2026. Microsoft offers the Extended Security Updates (ESU) program for these products, allowing critical security updates for a fee, with costs for Windows 10 Enterprise 2016 LTSB set to increase annually per device. ESU will also be available for Windows Server 2016, but pricing details are not yet released. Windows IoT Enterprise LTSB 2016 will receive extended support through hardware manufacturers, with terms and costs varying by supplier. Microsoft emphasizes that using unsupported software increases risks and that migrating to a newer version of Windows is the only long-term solution.

The Kremlin spent years building a messenger to replace Telegram. Now it’s reportedly telling soldiers the substitute is too insecure to use at the front.

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.

Is Messenger shutting down? Here’s the truth about Meta’s update

Meta announced the discontinuation of the Messenger website (messenger.com) effective April of this year, directing users to access messaging through facebook.com/messages. Users will be automatically redirected to this new address for messaging on a computer, and can continue using the Messenger mobile app. Those without a Facebook account will need to create one or reactivate an existing account to access their chats. The core messaging service will remain operational through the Facebook website and mobile app, despite speculation about the potential shutdown of Messenger. The standalone Messenger desktop applications for Windows and macOS were closed in December 2025.

Microsoft Introduces New Secure Boot Certificates Before June Deadline

The foundational security certificates supporting Windows Secure Boot, introduced in 2011, will expire in mid-2026, specifically in June and October. Microsoft and PC manufacturers are updating the Windows ecosystem to address this. Devices that do not receive updated certificates may face security limitations and compatibility issues with newer operating systems and hardware. The transition is described as a "generational refresh" of the trust infrastructure for Windows. Systems failing to update will still function but may enter a "degraded security state," unable to install new security mitigations or newer operating systems. Most users will receive updates automatically through Windows Update, while older systems may require manual intervention. Systems at risk include those running unsupported Windows versions, with Secure Boot disabled, or not enrolled in Extended Security Updates. Users should check their Secure Boot status using PowerShell commands to ensure they are using the new certificates. The update affects not only Windows PCs but also other devices utilizing UEFI Secure Boot.

eScan Antivirus Update Servers Compromised to Deliver Multi-Stage Malware

MicroWorld Technologies confirmed a breach of its eScan antivirus update infrastructure, allowing attackers to deliver a malicious downloader to enterprise and consumer systems. Unauthorized access was detected, leading to the isolation of affected update servers for over eight hours. A patch was released to revert the changes made by the malicious update, and impacted organizations were advised to contact MicroWorld for assistance. The attack occurred on January 20, 2026, when a compromised update was distributed within a two-hour window. The malicious payload, introduced through a rogue "Reload.exe" file, hindered eScan's functionality, blocked updates, and contacted an external server for additional payloads. This rogue executable was signed with a fake digital signature and employed techniques to evade detection. It also included an AMSI bypass capability and assessed whether to deliver further payloads based on the presence of security solutions. The malicious "CONSCTLX.exe" altered the last update time of eScan to create a false sense of normalcy. The attack primarily targeted machines in India, Bangladesh, Sri Lanka, and the Philippines, highlighting the rarity and seriousness of supply chain attacks through antivirus products.

CCP-Controlled Messaging App WeChat Used for ‘Coordination Among Chinese Criminal Networks’ in US, Sen Lankford Writes to Trump

Senator James Lankford has requested the White House to consider banning WeChat from U.S. app stores due to concerns about its use by Chinese criminal organizations for activities like drug trafficking and money laundering. WeChat, owned by Tencent Holdings Ltd., has been identified as a key tool for coordinating these criminal networks. U.S. law enforcement currently lacks access to WeChat's encrypted communications, complicating investigations. This request follows a previous attempt by the Trump administration to ban WeChat, which was deemed unconstitutional. The Biden administration has since conducted a national security assessment and enacted the Protecting Americans from Foreign Adversary Controlled Applications Act, which allows the president to blacklist Chinese applications like WeChat. The Pentagon has already blacklisted Tencent for its ties to Chinese military companies. Recent criminal activities linked to WeChat include a case where a Chinese national was charged with murder on an illegal marijuana farm. Lankford urges the designation of WeChat as a "covered company" to enhance U.S. national security and assist law enforcement against Chinese criminal networks.
