We’re halfway through the year, and the cybersecurity sector isn’t slowing down. As businesses settle into Q3, cybercriminals are also stepping up their game, using smarter methods and targeting organisations that let their guard down. If you haven’t reviewed your security posture recently, now is the time to do a mid-year check.

Here are seven critical cybersecurity threats you should be watching out for in the third quarter of the year, along with tips to stay ahead of them.

 

  1. Ransomware-as-a-Service (RaaS) Attacks Are Getting Smarter: Ransomware remains one of the biggest threats to businesses of all sizes. But what’s changing is how easy it is for attackers to launch these attacks. With Ransomware-as-a-Service platforms, even low-skilled criminals can rent ransomware tools to target you. These attacks can lead to data loss, downtime, and major financial damage.Tip: Keep your systems updated, train staff on phishing recognition, and maintain secure, regular backups.
  2. Business Email Compromise (BEC) on the Rise: Hackers aren’t just sending suspicious links anymore. They’re impersonating CEOs, finance heads, and vendors to trick employees into sending funds or sensitive data. With hybrid work environments still common, attackers are exploiting communication gaps more than ever.Tip: Enforce multi-factor authentication and educate teams to verify any unusual payment or data request.
  3. Cloud Security Misconfigurations: As more businesses shift to cloud platforms, misconfigurations are becoming a top vulnerability. Whether it’s open storage buckets, overly permissive access, or poor API security, attackers are quick to exploit these weaknesses.Tip: Regularly audit your cloud setup and follow best practices for access control and encryption.Read more:  5 Ways to Strengthen Your Cloud Security and Prevent Data Breaches|
  4. AI-Powered Phishing Campaigns: Cybercriminals are now using AI to craft convincing emails and messages. These phishing attempts are more targeted, well-written, and harder to detect than ever before. Tip: Invest in advanced email filtering solutions and train your staff to think critically before clicking or responding.Read more: Protecting Your Business From Phishing: Essential Tips to Note
  5. Supply Chain Attacks: Targeting a vendor or third-party service provider can give attackers access to your systems. These indirect attacks are becoming more common, especially in industries that rely heavily on outsourced IT services.Tip: Evaluate the security posture of your vendors and partners, and include cybersecurity clauses in contracts.
  6. Insider Threats, Both Malicious and Accidental: Whether it’s a disgruntled employee or someone who clicked the wrong link, insider threats can be just as dangerous as external ones. Human error remains one of the top causes of data breaches.Tip: Limit access based on roles, monitor user activity, and implement strong data loss prevention measures.
  7.  Unpatched Software Vulnerabilities: Software updates are often ignored or delayed, but this gives cybercriminals a perfect window to exploit known vulnerabilities. Unpatched systems remain one of the easiest ways for attackers to breach a network.Tip: Set up automated patching where possible and schedule regular vulnerability assessments.
