As per experts the areas that will get attention will be cloud security and data location. In 2025, new laws may require that sensitive data stay within national borders, affecting how companies manage and store data across regions. As businesses and critical services become increasingly dependent on cloud services, some countries may prioritize cloud availability in national emergency plans, recognizing that stable cloud access is mandatory for crisis management. This shift could lead towards the establishment of a new program like Cloud Service Priority (CSP), treating cloud infrastructure as important as utilities like electricity and telecoms.

How organization need to prepare themselves as big and small businesses and brands will see dramatically increased risks, as bad actors using AI will launch convincing impersonation attacks. This will make it easier with higher accuracy than ever to fool customers and clients. 

Key Cyber Security Trends of 2025

  • As organization navigate through 2025 we will witness that threat actors will increasingly use AI for sophisticated phishing, vishing, and social engineering attacks.

Gen-AI

  • Generative AI is driving an unprecedented surge in cyber fraud, with nearly 47% of organisations identifying adversarial AI-powered attacks as their primary concern, according to the World Economic Forum’s Global Cybersecurity Outlook 2025.
  • Due to technological advancements the Cyberspace is growing more complex due to technological advancements as they are interconnected to supply chains. Collaboration between public and private sectors is essential to secure the benefits of digitalization at all levels.

Digitalization

  • 76% of cybersecurity leaders report difficulties navigating a patchwork of global policies and 66% of organizations expect AI to transform cybersecurity, only 37% have implemented safeguards to secure these tools before deployment.

IoT Devices Vulnerable

  • Hackers will grow attacks on IoT devices as per research by Analytics insights report 2025 as over 30 billion devices across the globe will be connected through the Internet of Things. IoT enhance productivity offering convenience but due to their low-security backgrounds hackers may utilize opportunity to obtain sensitive information, or form massive botnets to execute Distributed Denial-of-Service (DDoS) attacks. (Analytics insight)

Technical Summary 

CVE-2024-6387, also known as “regreSSHion,” is a critical vulnerability in OpenSSH’s server (sshd) caused by a signal handler race condition. This issue arises when the SIGALRM handler, triggered during a failed login attempt exceeding LoginGraceTime, invokes non-async-signal-safe functions like syslog(). The Vulnerability allows unauthenticated remote attackers to execute arbitrary code with root privileges, primarily affecting glibc-based Linux systems.

Exploitation is technically complex but feasible and has been demonstrated in controlled environments on 32-bit systems. OpenBSD systems are unaffected due to their different signal-handling mechanisms. 

CVE ID System Affected Vulnerability Details Impact 
CVE-2024-6387 OpenSSH v8.5p1 through 9.8p1 on glibc-based Linux systems Signal handler race condition in sshd’s SIGALRM, triggered during login timeout (LoginGraceTime). Remote Code Execution (Root Privileges) 

Impact:

This Vulnerability if exploited could lead to complete system takeover.

Remediation

  • Immediate Patch: Upgrade OpenSSH to version 9.8p2 or later, which resolves the issue. 
  • Access Restrictions: Implement firewall rules or TCP wrappers to limit SSH access to trusted IP ranges.
