🚨 CAPTCHA Attacks? Hackers Are Now Using Verification Tests to Drop Malware

In a shocking twist, cybercriminals are weaponizing CAPTCHA challenges to execute malicious PowerShell commands, leading to severe malware infections. The latest HP Wolf Security Threat Insights Report reveals how unsuspecting users are lured to fake verification tasks on compromised websites. Once they comply, users inadvertently launch harmful scripts that download notorious malware like the Lumma Stealer.
Key Highlights:
• Attackers exploit user trust through fake CAPTCHA challenges.
• Malicious redirects and ads are common entry points.
• Employing DLL sideloading, the malware evades detection.
• Other threats include SVG images carrying malicious JavaScript and deceptive PDFs distributing keyloggers.
This alarming trend underscores the necessity for robust cybersecurity measures. Organizations should fortify their defenses by updating security software, disabling unnecessary features, and staying informed on emerging threats to combat these evolving cyber risks. Stay vigilant!

A surge in ransomware attacks exploiting critical VMware vulnerabilities has raised alarm bells worldwide, showcasing threats to enterprise infrastructures. Here are some key highlights:
• Vulnerabilities Detected: CVE-2025-22224 (CVSS 9.3), CVE-2025-22225 (CVSS 8.2), and CVE-2025-22226 (CVSS 7.1) are being actively exploited.
• Impact: Over 41,500 vulnerable ESXi hypervisors are exposed, enabling attackers to escape virtual machine security and deploy ransomware.
• Attack Strategy: Breaches often occur via internet-facing VMs, escalating privileges to access critical systems and encrypt data.
With ransomware demands averaging between $2 million to $5 million and the financial and healthcare sectors being heavily targeted, organizations must urgently patch their VMware systems. Broadcom has issued emergency updates, and the U.S. Cybersecurity and Infrastructure Security Agency (CISA) has flagged these vulnerabilities for immediate attention. The clock is ticking!
