GreyNoise Launches C2 Detection for Exploited Edge Devices
GreyNoise has introduced a new capability, C2 Detection, to identify compromised edge devices such as firewalls, routers, and VPN systems assets that are increasingly targeted but often lack visibility in traditional security tools. Unlike endpoints, these devices rarely generate alerts when exploited. There are no EDR agents, minimal logging, and almost no obvious signs of compromise.…

5 Steps to break free from alert fatigue and build resilient security operations
2. Prioritize outcomes over ticket volume : Stop focusing on how many alerts are cleared. This may be a metric for a better understanding of where automation or headcount are necessary but prioritize outcomes. Instead, the right questions are: How quickly did you contain a threat? Did we disrupt business operations or keep recovery swift and effective? A practical, outcome-driven SOC measures: Dwell time: How long before a threat was neutralized? Mean Time to Contain: How quickly…

Qilin Ransomware Deploys Malicious DLL to Disable Most EDR Defenses
The Qilin ransomware group has developed a highly sophisticated infection chain that targets and disables over 300 endpoint detection and response (EDR) solutions. As defenders improve behavioral detection capabilities, attackers are increasingly targeting the defense layer itself during the early stages of a breach. By deploying a malicious >>msimg32.dll<< file, attackers can bypass traditional antivirus…

Windows Tools Abused to Kill AV Ahead of Ransomware Attacks
Hackers are increasingly turning legitimate Windows administration tools into stealthy weapons to disable antivirus and EDR before launching ransomware, making attacks faster, quieter, and harder to stop. Instead of dropping noisy custom malware upfront, modern operators chain trusted utilities to gain SYSTEM access, kill security processes, and then encrypt at scale. Because many of these…
