PDFSIDER Malware Actively Used by Threat Actors to Bypass Antivirus and EDR Defenses

PDFSIDER is a sophisticated backdoor malware that bypasses modern endpoint detection and response systems. It is distributed through targeted spear-phishing campaigns that exploit vulnerabilities in legitimate PDF software. The malware is delivered via spear-phishing emails containing ZIP archives with a trojanized executable disguised as the PDF24 App. When executed, it uses DLL side-loading to load a malicious DLL (cryptbase.dll) alongside the legitimate PDF24.exe, allowing attackers to execute code without detection. PDFSIDER establishes encrypted command-and-control channels using the Botan 3.0.0 cryptographic library with AES-256 in GCM mode and operates mainly in memory to minimize detectable artifacts. It collects system information and executes commands through hidden cmd.exe processes. The malware employs advanced techniques to evade detection in sandbox and virtual machine environments, including checks for available RAM and debugger presence. Indicators of compromise include the malicious file cryptbase.dll and various clean files associated with the legitimate PDF24 application. Organizations are advised to enforce strict controls on executable files, provide user awareness training, and monitor DNS queries and encrypted traffic to detect PDFSIDER communications. The malware's behavior aligns with tactics used in state-sponsored espionage rather than financially motivated cybercrime.

Windows 11 shutdown bug: Microsoft confirms KB5073455 issue

Microsoft has acknowledged a shutdown issue affecting Windows 11 Enterprise and IoT editions after the January 13, 2026 security update (KB5073455) for version 23H2, which prevents affected systems from shutting down properly, causing them to either hibernate or restart instead. The problem is linked to the System Guard Secure Launch feature and does not affect Windows 11 Home and Pro editions. A temporary workaround involves using the command "shutdown /s /t 0" in an elevated Command Prompt to force a shutdown, but there is no workaround for hibernation functionality. Microsoft is working on a resolution and suggests that enterprise IT administrators consider pausing the deployment of the update on unaffected devices.

‘Fail To Shut Down’—Microsoft Issues Windows Update Warning

Microsoft has raised concerns about the shutdown process of Windows PCs, indicating complications following the January 13, 2026, security update. PCs with Secure Launch may fail to shut down or hibernate, instead restarting unexpectedly. A temporary solution is to use the Command Prompt with the command shutdown /s /t 0 for shutting down, but there is no workaround for the hibernation issue. Microsoft recommends saving work and shutting down devices to avoid power loss. Additionally, some users are facing credential prompt failures during Remote Desktop connections, affecting services like Azure Virtual Desktop and Windows 365. Alternatives include using the Remote Desktop client for Windows or the Windows App Web Client. An emergency update is expected to resolve these issues.

Microsoft Ends Windows Server 2008 Support on January 13, 2026

Microsoft has officially ceased all support for Windows Server 2008 as of January 13, 2026, including paid extended security updates. This end-of-life scenario poses significant security risks for organizations still using the outdated operating system, making them vulnerable to cyberattacks. The transition away from Windows Server 2008 requires careful planning, as many organizations face challenges in migrating legacy applications to modern systems. The lack of ongoing patches means that any new vulnerabilities will remain unaddressed, potentially leading to data breaches and compliance failures, particularly in regulated sectors like healthcare and finance. Microsoft has encouraged migration to Azure, offering incentives for early adopters, but the transition can be complex and costly. The end of support also affects global supply chains and compatibility with newer software applications. Organizations are advised to conduct audits of their software portfolios and consider hybrid environments to enhance flexibility and security.
