Hackers Use Over 240 Exploits Before Launching Devastating Ransomware Attacks
Cybercriminal groups are using hundreds of known software vulnerabilities to gain access to corporate networks before deploying ransomware, according to recent cybersecurity research.
Security analysts say threat actors have been observed leveraging more than 240 distinct exploits, targeting unpatched systems, outdated software, and exposed services as part of large-scale intrusion campaigns.
Broad Exploit Use Before Ransomware Deployment
Researchers report that attackers are no longer relying on a small number of high-profile vulnerabilities. Instead, they are scanning widely for any exploitable weakness that can provide initial access to a target environment.
Once access is gained, attackers often sell or transfer that foothold to ransomware operators or proceed directly to lateral movement and data exfiltration.
Targeted Technologies and Systems
The exploited vulnerabilities span a wide range of technologies, including:
- Operating systems and endpoint software
- Web applications and content management systems
- Network devices and remote access services
- Enterprise software and third-party components
Many of the vulnerabilities used are publicly disclosed and have available security patches, but remain unaddressed in affected environments.
Initial Access and Ransomware Operations
Security teams note that the extensive use of exploits reflects the growing role of initial access brokers, who specialise in compromising systems and selling that access on underground markets.
Ransomware groups increasingly depend on these access points to accelerate attacks, reducing the time required to infiltrate networks and deploy malware.
Evolving Tactics to Evade Detection
Analysts say attackers frequently combine vulnerability exploitation with legitimate administrative tools to evade detection. By blending malicious activity with normal system behaviour, threat actors can remain undetected for extended periods before launching ransomware.
This approach allows attackers to conduct reconnaissance, steal data, and disable security controls ahead of encryption.
Ongoing Risk to Organisations
Researchers warn that organisations remain at risk as long as critical systems remain unpatched or internet-facing services are improperly secured. The continued use of a large exploit set increases the likelihood that attackers will find a viable entry point.
Security teams say the trend highlights the importance of timely patching, vulnerability management, and monitoring of exposed systems.
Active Campaigns Continue
Threat intelligence teams report that campaigns leveraging large exploit inventories remain active, with new targets identified across multiple industries and regions. Further incidents are expected as attackers continue to expand their exploit toolsets.
