Hackers Use Fake VLC Executable and Malicious libvlc.dll to Deploy ValleyRAT

Cybercriminals are exploiting the VLC media player to install ValleyRAT, a remote access trojan, by embedding malware in a seemingly harmless file linked in phishing emails. The attack starts with an email that prompts the victim to download a ZIP archive containing a fake VLC executable and a malicious DLL named libvlc.dll. This method uses DLL sideloading to execute the malware under the guise of a legitimate application. Once executed, the malware establishes persistence by creating a registry entry and connects to a remote server to retrieve the final payload. ValleyRAT employs evasion tactics to avoid detection, including assessing system characteristics before executing harmful actions and using a fileless approach to deliver the payload directly into memory. Researchers have identified indicators of compromise, including specific SHA1 hashes and URLs associated with the malicious campaign.

Your Antivirus Has A Blind Spot, And Advanced Persistent Threats (APTs) Know Where It Is

Advanced Persistent Threats (APTs) are a type of cyber threat characterized by long-term infiltration aimed at stealing sensitive data or surveilling communications, often orchestrated by well-funded groups. Unlike traditional malware, which seeks immediate disruption, APTs employ a methodical approach, spending weeks mapping out networks and identifying valuable credentials. Traditional antivirus solutions often fail to detect APTs because they rely on signature-based detection, which is ineffective against custom malware. APTs frequently use legitimate tools already present on systems, making detection challenging, and some forms of APTs operate directly from memory without writing to disk, evading traditional scans. To combat APTs, a multifaceted strategy is recommended, including behavioral detection, network monitoring for unusual patterns, and a mindset of skepticism towards all network activities.

Windows 95 used a very basic “trick” to detect setup files

Microsoft developed Windows 95 with innovative detection mechanisms to prevent external installers from downgrading essential system components. The team used a heuristics-based approach to identify installer files by analyzing their names for keywords like "setup," "installer," or "inst," and also considered variations in other languages. If these keywords were not present, the system would check the file path for "setup." File checks were delayed until the next start to catch improperly modified files, as some setup programs would exit Windows to run batch files. Additionally, live file checks were conducted for multimedia driver installations via INF files, which was a special exception.

Companies are now using automatic Windows installers to display Adware through the Microsoft Store when you install new hardware — customer immediately gets McAfee ads on their PC after connecting new LG monitor; here’s how to block the new ads

LG monitors are displaying unsolicited advertisements for McAfee, which users find intrusive and frustrating. This issue arose when the LG Monitor App Installer was automatically added to users' PCs, similar to how some motherboard software integrates during Windows reinstallation. Reports indicate that this is not an isolated incident, as other users have experienced the same problem. Additionally, other manufacturers like Alienware and Samsung may be engaging in similar practices, facilitated by a Microsoft policy that allows automatic downloads of related monitor software. This trend raises concerns about user consent and the prevalence of unwanted software installations.

7 Habits That Are More Important Than Using Antivirus on Your Phone

Antivirus software was once standard on personal computers, but modern smartphones have evolved with enhanced security measures from Apple and Google, making them less vulnerable to traditional malware. Smartphones isolate applications, allowing them only to access user-permitted information, and if a malicious app infiltrates, it faces significant challenges due to built-in defenses. Apple requires thorough vetting of apps through the App Store, which enhances security but limits antivirus capabilities. Android allows sideloading apps from outside the Google Play Store, which introduces risks but also includes built-in security features like Google Play Protect and regular updates. Despite these advancements, smartphones can still be compromised, and cybercriminals increasingly target user accounts through phishing tactics rather than malware. Security experts recommend focusing on phishing awareness, strong passwords, and two-factor authentication. For enhanced security, users should keep devices updated, download apps from official sources, review app permissions, use strong passwords, utilize a password manager, enable two-factor authentication, and be cautious with unexpected communications. While most users may not need antivirus apps, those who frequently sideload or download from unfamiliar sites may benefit from additional security tools.

Why Antivirus Alone No Longer Protects Small Businesses

Many small businesses have historically relied on antivirus software for computer security, which was effective against identifiable malware. However, the current cyber threat landscape includes sophisticated attacks such as phishing, credential theft, and ransomware that traditional antivirus solutions may not adequately address. Factors driving increased cyber threats in Kenya include phishing, weak authentication practices, delayed software updates, and the use of artificial intelligence by malicious actors. While antivirus software can detect known malware and block common threats, it falls short against tactics like stolen credentials and social engineering. The Communications Authority recommends complementing antivirus with multi-factor authentication, regular software updates, secure configurations, and user training. Endpoint Detection and Response (EDR) solutions enhance visibility into attacks by monitoring endpoint activity for suspicious behaviors, allowing for prompt investigation and response. A layered security strategy that integrates multiple protective measures is essential for effective cybersecurity, and many modern security platforms offer unified solutions to simplify management for smaller organizations. The Kaspersky SMB Cybersecurity Guide provides insights into modern attack methods and the role of endpoint protection in improving a business's cybersecurity posture.

Hackers Use Fake VLC Executable and Malicious libvlc.dll to Deploy ValleyRAT

Cybercriminals are using a sophisticated method to bypass security measures by embedding malware within the VLC media player. This campaign exploits VLC to install ValleyRAT, a remote access trojan, through phishing emails that contain links to download a seemingly harmless file. Once the file is opened, it activates a hidden backdoor that evades detection by antivirus solutions. The malware has been active since 2023, with a significant increase in activity noted through 2025 and into 2026, particularly targeting Chinese and Japanese-speaking users. The infection process begins when a victim clicks a link in a phishing email, leading to a ZIP archive containing a disguised executable and a malicious DLL (libvlc.dll). The executable mimics a legitimate VLC file, and when executed, it loads the DLL, allowing the malware to run under the guise of VLC. The malware establishes persistence by creating a registry entry and connects to a remote server to retrieve the final payload. ValleyRAT employs evasion tactics to avoid detection, such as performing checks on system behavior and using a fileless approach to inject its payload directly into memory, avoiding storage on disk. Researchers recommend training employees to recognize suspicious filenames and deploying endpoint detection tools to identify DLL sideloading behavior. For organizations affected by this campaign, isolating compromised systems and reviewing security logs are critical initial steps. Indicators of compromise include a malicious email domain, a ZIP archive containing a fake VLC executable, and a download URL for ValleyRAT.
