Real-World Cyber Attack Detection: How Modern SOCs Identify, Block, and Contain Advanced Threats
Executive Summary Modern cyberattacks rarely appear as a single, obvious incident. Instead, they manifest as multiple low-level signals across web, endpoint, DNS, cloud, and network telemetry. When analyzed in isolation, these signals may seem benign. When correlated intelligently, they reveal active attack campaigns targeting applications, identities, cloud storage, and network boundaries. This article presents a…

Chinese PlushDaemon Hackers Exploit EdgeStepper Tool to Hijack Legitimate Updates and Redirect to Malicious Servers
ESET researchers have uncovered a sophisticated attack chain orchestrated by the China-aligned threat actor PlushDaemon, revealing how the group leverages a previously undocumented network implant, EdgeStepper, to conduct adversary-in-the-middle attacks. By compromising network devices and redirecting DNS queries to malicious servers, PlushDaemon intercepts legitimate software updates and replaces them with trojanized versions containing the SlowStepper…

This external intelligence gives us the who and how behind potential exploitation.For example, when a privilege escalation vulnerability in Linux…
