Cyber Threat Landscape: Ransomware on the Rise, Cisco Attacks, and Critical VMware Flaws
October Kicks Off With a Bang: New Reports and Old Threats
The first day of October greeted us not only with the start of the European Cybersecurity Month but also with a few powerful punches that remind us there's never a dull moment in the digital world. It seems cybercriminals aren't slowing down, and system administrators have their hands full.
Ransomware Attacks on the Rise Again
Remember how we've been enjoying a slight decline in ransomware attacks over the past few years? Well, the good times are officially over. A new report from Hornetsecurity reveals that in 2025, one in four companies (24%) fell victim to a ransomware attack, a significant increase from 18.6% the previous year. This is the first such increase in three years! Interestingly, analysts link this trend to the growing use of artificial intelligence tools by attackers to automate and enhance their campaigns. Fewer companies are also opting for insurance against such attacks. Are we heading into a new era of digital ransoms? Time will tell.
Your Network Under Fire: Cisco Zero-Day Vulnerabilities
If your company uses Cisco Adaptive Security Appliances (ASA), we have bad news. Cybersecurity agencies worldwide, including the U.S. CISA, are sounding the alarm about an active campaign exploiting zero-day vulnerabilities in these popular firewalls. The attacks are attributed to advanced state-sponsored groups. By exploiting the flaws, attackers can take control of the devices, deploy malware, and gain access to internal corporate networks. CISA has even issued a directive ordering government agencies to patch vulnerable systems immediately. This is no joke—check your firewalls before someone else does it for you.
VMware Patches Holes – Update Before It's Too Late
To wrap up, here's something for users of virtual environments. VMware has just released a set of critical security updates for its popular products, including Aria Operations, NSX, and vCenter. Although the technical details are still being analyzed, the vulnerabilities have been rated as "high severity." Given how widely these solutions are used, the potential attack surface is enormous. There's no time to wait—administrators, get to it!
It looks like this autumn in cybersecurity is going to be a hot one. Remember to perform regular updates and stay vigilant.
