Organizations should apply updates to versions 10.2.1.0-17sv or later to mitigate potential risks.
Cyber Attacks
1. Chinese Hackers Exploiting Ivanti VPN Vulnerability
A critical buffer overflow flaw (CVE-2025-22457) in Ivanti Connect Secure VPN appliances is being actively exploited by Chinese threat actors. The attackers deploy sophisticated malware like TRAILBLAZE and BRUSHFIRE to maintain persistence and evade detection. Organizations are urged to update to version 22.7R2.6 or later to protect their systems.
2. DarkCloud Stealer Targets Spanish Organizations
The DarkCloud information stealer is leveraging phishing emails with weaponized .TAR archives to target Spanish entities in technology, legal, financial, and government sectors. The malware harvests credentials, cryptocurrency wallets, and sensitive files while evading detection. Organizations should enhance their email security measures and educate employees on recognizing phishing attempts.
3. Qilin Ransomware Mimics ScreenConnect Login Pages
Qilin ransomware affiliates are using phishing campaigns to impersonate ScreenConnect login pages, bypassing multi-factor authentication protections and deploying ransomware across Managed Service Providers (MSPs) and their customers. This highlights the growing risks of supply chain attacks. Organizations should verify the authenticity of login pages and implement robust security protocols.
4. Russian Seashell Blizzard Intensifies Global Attacks
The Russian-linked Seashell Blizzard group has escalated its operations, targeting critical infrastructure sectors like energy and telecommunications worldwide. Their “BadPilot” campaign exploits software vulnerabilities to gain persistent access. Organizations in these sectors should conduct thorough security assessments and apply necessary patches to safeguard their systems.
5. Apache Tomcat Vulnerability Under Active Exploitation
A critical flaw (CVE-2025-24813) in Apache Tomcat allows attackers to take control of servers or steal sensitive data via malicious file uploads. Organizations using affected versions are advised to apply patches immediately to prevent potential breaches.
6. Over 1,500 PostgreSQL Servers Compromised
A fileless malware campaign has exploited misconfigured PostgreSQL instances globally, deploying cryptominers like XMRig-C3. The malware operates entirely in memory, making it difficult to detect. Administrators should review their PostgreSQL configurations and implement security best practices to prevent unauthorized access.
7. 20,000 WordPress Sites Vulnerable to File Upload Exploits
Two high-risk vulnerabilities in the WP Ultimate CSV Importer plugin (CVE-2025-2008 and CVE-2025-2007) allow attackers to upload malicious files or delete critical site files, leading to full site compromise. Website owners using this plugin should update to the latest version and monitor their sites for unusual activity.
