Researchers Uncovered Hackers Infrastructre Using Passive DNS Technique

Cybersecurity researchers have unveiled an advanced technique to uncover hackers’ operational infrastructure using passive DNS data.

This groundbreaking method sheds light on how attackers establish and maintain their networks to perpetrate malicious activities while remaining resilient to detection.

By leveraging passive DNS analysis, experts have made significant strides in identifying threats before they wreak havoc, thus fortifying defenses against evolving cyber threats.

Understanding Attack Infrastructure

The backbone of any cyberattack lies in its infrastructure, which consists of servers, domains, and compromised devices. Attackers employ various tactics to maintain their operations while evading detection.

A popular method is infrastructure churn, where hackers frequently change domains and IPs when one server is detected and blocked. This differs from DNS fast flux, which involves rapid, automated IP rotation for a single domain.
