Cyber Threat Detection and Ransomware Attacks

Cyber threat detection before operations are affected

Modern ransomware attacks can remain undetected for weeks

When production lines stop because of a ransomware attack

Last year, one of the largest food industry producers in Romania experienced the scenario many IT directors still consider theoretical: production systems were encrypted, production lines stopped, and orders could no longer be fulfilled. Damages reached nearly one billion euros and included operational losses, contractual penalties and recovery costs. The attack did not happen suddenly. There was a period of activity inside the network that nobody detected in time.

Modern ransomware no longer enters a system and immediately encrypts it. The actors behind these attacks spend weeks or even months inside the victim’s infrastructure mapping systems, escalating privileges, exfiltrating sensitive data, and only then launching the attack.

Cyber threat detection: the difference between weeks and minutes

The most costly mistake organizations make is operating in silos and lacking a correlated view of what is happening in real time.

Modern cyber threat detection platforms collect and correlate events from multiple sources, including endpoints, networks, applications, and identities, identifying abnormal behavior patterns before they become incidents. SIEMBIOT provides organizations with exactly this capability: centralized visibility and detection based on event correlation and contextual analysis. When a service account suddenly accesses large volumes of files at 3 AM or when an internal system communicates with an unknown domain, these signals are automatically correlated and the responsible team is notified.

The difference between an organization that detects and contains an attack within 20 minutes and one that discovers it after 40 days lies in the visibility it has across its infrastructure.

Continuous visibility means more than monitoring the perimeter. Effective threat monitoring covers internal users, OT/IT systems, vendors with network access, and connected devices that are often excluded from the traditional security perimeter. In the food industry, or in any sector operating critical infrastructure, a compromised PLC or an unsecured SCADA system can become the entry point that leads to production shutdowns.

Continuous infrastructure monitoring means security teams do not react only to isolated alerts, but operate with a complete view of what is happening across their environment. This visibility is what makes the difference between a minor incident and a major operational crisis.

A SIEM (Security Information and Event Management) is a platform that centralizes and analyzes security events across an organization's entire IT infrastructure. Instead of firewalls, endpoint protection solutions, servers, applications, and cloud services generating isolated alerts, a SIEM correlates them into a unified view of activity across the organization.

This correlation is essential because most modern attacks cannot be identified based on a single event. An attacker may compromise an account, access internal systems, escalate privileges, and exfiltrate data over the course of days or even weeks. Viewed in isolation, these actions may appear insignificant. When analyzed together, they reveal an attack in progress.

Through its SIEM capabilities, SIEMBIOT collects and correlates data across the entire infrastructure, providing security teams with real-time visibility into active threats and generating alerts when attack patterns are identified. As a result, organizations can detect and investigate incidents more quickly, reducing operational and financial impact before they disrupt business operations.
