Ransomware Surge and Exploited Vulnerabilities: Verizon's Alarming Report

In 2024, cybercriminals and state-sponsored threat groups have escalated their efforts, exploiting vulnerabilities and launching ransomware attacks with increased sophistication. Verizon’s 2025 Data Breach Investigations Report (DBIR), which covers incidents between November 2023 and October 2024, paints a disturbing picture of the rising tide of cybercrime and its growing impact on organizations globally. Not only did ransomware attacks rise significantly, but the methods used to infiltrate systems have also evolved, making defenses less effective and pushing businesses into a more vulnerable position.

Ransomware Attacks on the Rise: A Wake-Up Call for Cybersecurity

Verizon’s latest findings show that ransomware was a factor in 44% of all data breaches analyzed, a stark increase from the 32% detected in the previous year. This jump is alarming, particularly as the scope of these attacks continues to expand, impacting small to medium-sized businesses (SMBs) more than ever before. The report reveals that 88% of breaches involving SMBs had a ransomware component, highlighting the growing targeting of these often under-resourced organizations.

Interestingly, while the number of ransom payments has decreased—64% of victims chose not to pay in 2024, up from 50% in 2022—the frequency of ransomware attacks has not slowed. Instead, the attackers are diversifying their strategies, exploiting more vulnerabilities, especially those in VPNs and edge devices. Furthermore, the median amount paid to ransomware groups has dropped from $150,000 in 2023 to $115,000 in 2024, indicating that while organizations are increasingly reluctant to pay, the economic impact of these attacks remains substantial.

One of the key drivers behind this increase in ransomware is the surge in exploited vulnerabilities, particularly in network edge devices and virtual private networks (VPNs). Verizon found a staggering 34% increase in the use of exploited vulnerabilities as an initial access vector for breaches, now accounting for 20% of all incidents.

The most troubling aspect of these findings is the poor response time and patching efforts by many organizations. Despite a large volume of exploitable vulnerabilities, only 54% of edge device vulnerabilities were fully remediated in 2024, with an average time to patch taking a median of 32 days. This delay leaves organizations exposed to prolonged periods of risk, allowing cybercriminals to launch devastating attacks.

What Undercode Say:

The Verizon 2025 report is a stark reminder of the evolving nature of cyber threats, particularly in the realm of ransomware and exploited vulnerabilities. Attackers are not only becoming more adept at identifying weak points within networks, but they are also increasingly targeting edge devices and VPNs—critical infrastructure often overlooked by security teams.

The significant rise in ransomware attacks in 2024, coupled with the growing targeting of SMBs, signals a shift in the threat landscape. Traditionally, larger organizations were the primary focus of cybercriminals, but now SMBs are facing an unprecedented wave of attacks. The fact that 88% of breaches involving SMBs had a ransomware component highlights a worrying trend: smaller companies are not only being targeted more frequently, but they are also suffering from greater financial and operational damage. These organizations often lack the resources to implement robust cybersecurity measures, leaving them vulnerable to exploitation.

The trend toward exploiting vulnerabilities as an initial access point also underscores the need for stronger patch management and vulnerability remediation practices. The increase in the number of attacks leveraging zero-day exploits against VPNs and edge devices—combined with the slow pace of remediation—suggests that many organizations are still not prioritizing these areas of their networks. The fact that many companies took more than 30 days to address vulnerabilities is unacceptable, given the speed at which cybercriminals are evolving their attack strategies.

Another critical point is the rise in third-party vendor involvement in breaches. The increase from 15% to 30% in breaches involving third-party vendors indicates that organizations are facing a growing risk from their supply chain. Many companies outsource critical functions, yet fail to fully vet the cybersecurity practices of their partners. This highlights a crucial blind spot in many organizations’ security postures.

The continued prevalence of ransomware, exploited vulnerabilities, and third-party risks suggests that cybercriminals are simply maximizing their opportunities. They are not necessarily changing their tactics, but rather adapting to exploit the expanding attack surface of organizations. This evolution in cybercrime tactics means that businesses must stay vigilant and prioritize the implementation of robust cybersecurity measures across all areas, from patching vulnerabilities to securing vendor relationships.
