Newly Discovered Vulnerabilities
- Oracle E-Business Suite: A critical remote code execution vulnerability (CVE-2025-61882) has been exploited in the wild by the Cl0p ransomware group. Oracle has released an emergency patch.
- GoAnywhere MFT: Microsoft reported that Storm-1175 has been exploiting a maximum severity vulnerability in GoAnywhere MFT for Medusa ransomware attacks for nearly a month.
- Redis: The Redis security team released patches for a maximum-severity vulnerability that could allow remote code execution on thousands of exposed instances.
- Unity Game Engine: A code execution vulnerability in the Unity engine could enable attackers to gain code execution on Android and privilege escalation on Windows. Microsoft and Steam have issued warnings and are taking action.
- Zimbra: Attackers exploited a zero-day vulnerability in Zimbra via ICS files, targeting Brazilian military entities.
- BitLocker Bypass and VMScape vulnerabilities were also highlighted in recent security roundups.

Trends, Tools, or Tactics of Interest
- AI-driven phishing and social engineering attacks are cited as a top concern by nearly 40% of surveyed security leaders.
- Machine learning models for detecting DLL hijacking have been developed and integrated into Kaspersky SIEM, enabling early incident detection.
- Increased use of AI in cybersecurity, including open-source XDR/SIEM platforms like Waziuh and the risk of insecure AI-generated code (“vibe coding”).
- XWorm’s modular architecture and plugin system highlight evolving malware sophistication.
- High-profile phishing and social engineering attacks continue to leverage realistic lures and automation.
- Self-propagating malware targeting messaging platforms (e.g., WhatsApp) is being used for credential theft and financial fraud.
- The launch of the Zeroday.Cloud hacking competition offers $4.5 million in bounties for exploits targeting open-source cloud and AI tools.
Notable Threat Actor Attribution
- CrowdStrike attributes recent Oracle EBS exploitation to Graceful Spider (aka Cl0p).
- Chinese research firms BIETA and CIII have been linked to the Ministry of State Security (MSS) and assessed as fronts for PRC cyber operations.
- Reports highlight Chinese government fronts collaborating with Western organisations to acquire cyber technologies for state intelligence purposes.
Regulatory or Policy Developments Affecting the Security Industry
- LinkedIn has filed a lawsuit against ProAPIs Inc. and its founder for scraping user data via over one million fake accounts, addressing large-scale data harvesting.
- Compliance training updates and frameworks (e.g., KnowBe4’s Compliance Plus and the DEEP Matrix for unified defence) are being promoted to address evolving human risk management and regulatory requirements.
