Hackers Are Using Fake Invitations to Take Over Your PC

Cybercriminals are sending counterfeit email invitations that, when clicked, install a backdoor on the victim's computer, allowing hackers full control. The scam often involves downloading a file named “invites.msi,” which is a Windows Installer package. This file can install ScreenConnect, a legitimate remote support tool that can be exploited by attackers to monitor screens, access files, and deploy additional malware. Many security engines fail to flag this software as malicious, making it difficult to detect. If someone suspects they have fallen victim to this scam, they should disconnect from the internet, check for and uninstall any remote management software, run a comprehensive antivirus scan, change passwords for critical accounts, enable two-factor authentication, inform their IT department if applicable, and consider performing a full Windows reset. The scam originated from a compromised email account, which was used to send the malicious link to contacts. Implementing two-factor authentication and using a password manager can help prevent such incidents. Users should be cautious of any email invitations that require downloading and running installer files.

Do You Still Need Antivirus Software? Here’s What Experts Say

Browser extensions are important for online security, but their effectiveness depends on avoiding pirated software and untrustworthy applications. Regular updates to antivirus software, such as Microsoft Defender, are crucial to prevent vulnerabilities, and it is recommended to configure Windows Security settings for auto-updates. While Microsoft Defender can protect against malware, it may not be sufficient against advanced threats like ransomware and phishing, particularly for individuals handling sensitive data. Alternatives to Microsoft Defender include Bitdefender Total Security and Norton 360, which offer additional features. Upgrading from Windows 11 Home to Pro provides enhanced security features. For enterprise use, AhnLab V3 Endpoint Security and Avast Ultimate Business Security are recommended for their protection and performance.

EDRStartupHinder Disables Antivirus and EDR Protections During Windows 11 25H2 Startup

A new tool named EDRStartupHinder was unveiled on January 11, 2026, which allows attackers to inhibit the launch of antivirus and endpoint detection and response (EDR) solutions during the Windows startup process. Developed by security researcher Two Seven One Three, it targets Windows Defender and various commercial security products on Windows 11 25H2 systems by redirecting essential system DLLs during boot using the Windows Bindlink API and Protected Process Light (PPL) security mechanisms. The tool employs a four-step attack chain that includes creating a malicious service with higher priority than the targeted security services, redirecting critical DLLs to attacker-controlled locations, and modifying a byte in the PE header of the DLLs to cause PPL-protected processes to refuse loading them. This results in the termination of the security software. EDRStartupHinder has been tested successfully against Windows Defender and other unnamed antivirus products, demonstrating its effectiveness in preventing these security solutions from launching. The source code for EDRStartupHinder is publicly available on GitHub, raising concerns about its potential misuse. Security teams are advised to monitor for Bindlink activity, unauthorized service creation, and registry modifications related to service groups and startup configurations to detect this attack vector. Microsoft has not yet issued any statements regarding patches or mitigations for this technique.

Antivirus vs Endpoint Security in 2025: Which Protection Do You Really Need?

In 2025, users must choose between traditional antivirus software and modern endpoint security solutions for their digital safety. Antivirus software has evolved to include machine learning and cloud-based threat analysis, effectively combating various malware types but primarily protects individual devices. It is user-friendly and suitable for casual users but struggles against sophisticated attacks and lacks centralized management. Endpoint security, on the other hand, secures all network-connected devices and employs advanced technologies like AI-driven threat detection and real-time behavioral analytics. It offers proactive monitoring and automated threat responses, making it essential for businesses and professionals handling sensitive information. Endpoint security provides centralized management and a broader range of protections but is typically more expensive and may require technical expertise to set up. The choice between the two solutions depends on individual needs: casual users may prefer antivirus software, while professionals and businesses benefit from the comprehensive protection of endpoint security. As cyber threats become more complex, endpoint security is becoming the standard due to its proactive and automated defense capabilities.

Microsoft Silently Patches Windows LNK Flaw After Years of Active Exploitation

Microsoft has addressed a long-standing security vulnerability, identified as CVE-2025-9491, which has been exploited since 2017. This vulnerability involves a misinterpretation issue within Windows Shortcut (LNK) files, potentially allowing remote code execution. The flaw was highlighted in the November 2025 Patch Tuesday updates, with a CVSS score of 7.8/7.0. It allows crafted .LNK files to obscure harmful content, making it invisible to users, thus enabling attackers to execute code under the current user's context. The vulnerability was exploited by various state-sponsored groups, including those from China, Iran, North Korea, and Russia, for data theft and espionage. Microsoft initially deemed the flaw not warranting immediate attention, citing user interaction requirements and existing system warnings. Subsequent investigations revealed its exploitation by cyber espionage groups, including XDSpy and China-affiliated actors targeting European entities. The recent patch aims to ensure that the entire Target command is displayed in the Properties dialog, while 0patch provides warnings for LNK files exceeding 260 characters.

Dragon Breath Uses RONINGLOADER to Disable Security Tools and Deploy Gh0st RAT

The threat actor Dragon Breath, also known as APT-Q-27 and Golden Eye, has been observed using a multi-stage loader called RONINGLOADER to deploy a modified variant of the remote access trojan Gh0st RAT, primarily targeting Chinese-speaking users. The campaign employs trojanized NSIS installers disguised as legitimate applications, such as Google Chrome and Microsoft Teams. The infection chain utilizes various evasion techniques, including a legitimately signed driver, custom Windows Defender Application Control policies, and manipulation of the Microsoft Defender binary. RONINGLOADER's attack chain involves delivering a DLL and an encrypted file labeled "tp.png," which contains shellcode. It attempts to neutralize security products by terminating processes associated with popular antivirus solutions in the region. Specific actions are taken against Qihoo 360 Total Security, including blocking network communication, injecting shellcode into the Volume Shadow Copy service, and restoring firewall settings. For other security processes, RONINGLOADER directly writes a driver to disk to perform process termination. The malware aims to inject a rogue DLL into "regsvr32.exe" to conceal its activities and launch a next-stage payload into high-privilege system processes. The final payload is a modified version of Gh0st RAT, capable of communicating with a remote server, configuring Windows Registry keys, clearing Windows Event logs, and capturing keystrokes and clipboard contents. Additionally, two interconnected malware campaigns identified by Palo Alto Networks Unit 42 employed brand impersonation to deliver Gh0st RAT to Chinese-speaking users. The first campaign, Campaign Trio, occurred between February and March 2025, while the second, Campaign Chorus, detected in May 2025, impersonated over 40 applications. Both campaigns utilized complex infection chains and trojanized installers hosted on domains that circumvented network filters. The second campaign also involved an embedded Visual Basic Script for launching the final payload through DLL side-loading.
