Trend Micro releases critical security fixes for Apex Central RCE

Trend Micro has addressed a security vulnerability in its Apex Central platform, identified as CVE-2025-69258, which allowed unauthenticated DLL injection and remote code execution. The company released Critical Patch Build 7190 to fix this vulnerability and two others, CVE-2025-69259 and CVE-2025-69260. Organizations are urged to implement the patch immediately, as temporary mitigations are deemed insufficient for long-term security. Apex Central is a self-hosted platform for managing Trend Micro's security products.

New DefenderWrite Tool Allows Attackers to Inject Malicious DLLs into AV Executable Folders

DefenderWrite is a new tool that uses whitelisted Windows programs to bypass antivirus protections and write files into executable folders. Developed by cybersecurity expert Two Seven One Three, it allows penetration testers to deploy payloads in secure locations without needing kernel-level access. The tool identifies whitelisted system programs, enabling attackers to inject malicious DLLs into antivirus folders. In tests on Windows 11 with Microsoft Defender, four vulnerable programs were identified: msiexec.exe, Register-CimProvider.exe, svchost.exe, and lsass.exe. DefenderWrite includes parameters for targeted operations and a PowerShell script for scanning executables. It highlights the need for antivirus vendors to improve their whitelisting policies and process isolation. The tool is publicly available, raising concerns about its potential use in real-world attacks.

5 apps that are way better on Linux than they are on Windows

GIMP and Krita perform better on Linux due to their native integration with system libraries (GTK for GIMP and Qt for Krita), resulting in a more responsive user experience compared to Windows. Kdenlive, a video editing software, is more stable on Linux, with fewer crashes and better performance due to its native MLT framework, while the Windows version often experiences issues. OBS Studio benefits from direct access to hardware resources on Linux, leading to lower latency and reduced CPU/GPU load, while capturing per-application audio is easier on Linux. VLC Media Player on Linux comes with full codec support out of the box, unlike the Windows version, which requires additional downloads. Linux's package management system allows for centralized software distribution and efficient dependency tracking, making it more secure and streamlined than Windows' fragmented approach to software management.

Hackers are impersonating credit card companies to infect your PC with password-stealing malware — how to stay safe

Cybercriminals are using a new phishing tactic that involves sending emails that mimic legitimate communications from credit card companies, prompting recipients to confirm purchases through deceptive links. These links lead to fake webpages where malware is initiated through DLL files. One technique, Reflective DLL Injection, allows hackers to inject malware into the Chrome browser's memory, enabling keylogging and data theft. This can result in the capture of sensitive information like login credentials and credit card numbers, leading to account takeovers and identity theft. To stay safe, individuals should avoid clicking on links in suspicious emails, verify destinations, use two-factor authentication, employ strong passwords, and invest in antivirus software.

Hackers Allegedly Selling Windows Crypter Claims Bypass of All Antiviruses

Underground cybercriminal forums are seeing an increase in advanced malware tools, including a Windows crypter that claims to bypass major antivirus solutions. This crypter is marketed as fully activated and capable of achieving Full Undetectable (FUD) status against contemporary antivirus engines. It employs advanced obfuscation techniques to evade detection, including code injection methods, entropy manipulation, and anti-debugging features. The tool allows for granular control over obfuscation parameters, enabling customization for specific target environments. The rise of such sophisticated evasion tools poses challenges for traditional endpoint security, making organizations vulnerable if they rely solely on signature-based antivirus solutions. To defend against these threats, organizations should adopt multi-layered security architectures, including behavioral analysis and endpoint detection and response (EDR) solutions.

0-Day Vulnerabilities in Microsoft Sysinternals Tools Allow Attackers To Launch DLL Injection Attacks on Windows

A critical 0-Day vulnerability has been identified in Microsoft Sysinternals tools, allowing attackers to exploit DLL injection techniques to execute harmful code. This vulnerability has been verified and remains unresolved despite being disclosed to Microsoft over 90 days ago. The Sysinternals tools, including Process Explorer, Autoruns, and Bginfo, are widely used for system analysis and troubleshooting but lack integration with the Windows Update system, requiring manual management of security patches. The vulnerability stems from how Sysinternals tools load DLL files, prioritizing untrusted paths over secure system directories. Attackers can place a malicious DLL in the same directory as a legitimate Sysinternals executable, leading to the execution of arbitrary code under the user's privileges. A real-world example demonstrated that an attacker could deploy a Trojan via the Bginfo tool by loading a malicious DLL from a network directory. The vulnerability affects multiple Sysinternals applications, and a comprehensive list is available from the researcher. Microsoft has classified the issue as a "defense-in-depth" enhancement rather than a critical vulnerability, focusing on local execution rather than risks associated with network paths. As of December 2024, the vulnerability remains unpatched, prompting users to take precautionary steps such as avoiding running tools from network locations and verifying DLL integrity.
