Newly Discovered Vulnerabilities

ASUS Server Vulnerability (CVE-2024-54085): ASUS released patches for a critical AMI bug that could allow attackers to hijack and potentially brick servers.
Kubernetes Permissions Risk: Research highlights that Kubernetes pods are often provisioned with excessive permissions, increasing risk of lateral movement and privilege escalation.

Notable Threat Actor Activity

Lazarus Group (North Korea): Operation SyncHole is a new campaign using watering hole attacks to exploit vulnerabilities in South Korean software, targeting specific user groups.
DPRK Crypto Theft: North Korean threat actors stole $137 million from TRON blockchain users in a single-day phishing attack, reflecting ongoing targeting of Web3 and cryptocurrency sectors.

Trends, Tools, and Tactics

Ransomware Evolution:
- Ransomware remains the dominant threat for SMBs, responsible for over 90% of incident response cases for medium businesses and 70% for small businesses in 2024.
- Groups such as DragonForce and Anubis are innovating with new affiliate business models and ransomware-as-a-service offerings to scale operations and profits.
Phishing Tactics:
- Phishing detection is increasingly ineffective, with attacks often evading traditional filters, proxies, and even MFA, making each incident akin to a zero-day.
- Attackers are shifting towards identity-based phishing rather than exploiting software vulnerabilities.
- Browser-based, real-time detection is emerging as a more effective countermeasure.
- Employee awareness training, particularly phishing simulations, is widely recognised (90% approval in surveys) as improving security posture.
Privacy and Security Enhancements:
- WhatsApp introduced Advanced Chat Privacy, preventing chat exports and auto-downloads to better protect sensitive conversations.
AI Security: Research proposes using hypervisors to isolate and regulate the behaviour of potentially malicious AI systems in critical sectors.

Regulatory and Policy Developments

FTC on AI Regulation: The US Federal Trade Commission signals a cautious approach, aiming to avoid excessive regulation that could hinder AI innovation.
CISA Energy Sector Collaboration: CISA, DHS S&T, INL, and LSU are working with the energy industry to bolster incident response and operational technology (OT) cybersecurity.
Cloudflare Internet Shutdown Trends: Government-imposed internet shutdowns dropped to zero in Q1 2025, indicating a shift in government tactics for information control.

Industry Developments

Microsoft Security Culture: Microsoft reports ongoing efforts to prioritise and embed security within its corporate culture, including linking security to employee performance reviews.
