Questions about this signal

What happened in this signal?

The 'FortiBleed' cyber campaign, which previously exposed login credentials for thousands of Fortinet firewalls, has now been linked to the ransomware groups INC and Lynx. Forensic investigations revealed evidence on a Windows server used in the attack infrastructure, showing administrators had access to negotiation portals of both ransomware groups. This suggests a strong connection between the credential theft and subsequent extortion campaigns. Researchers estimate that over 430,000 FortiGate firewalls worldwide were targeted, with sniffers installed on approximately 19,000 systems to intercept network traffic.
