Attackers exploit gaps between alerts to evade detection

The Hacker News reports on how attackers increasingly exploit gaps between alerts to avoid detection, a pattern the piece terms “silent progression.” It notes that while SOCs often see only individual alerts—triggered by malware hashes, login thresholds, or endpoint flags—the real intrusion often unfolds as a connected sequence of events that can stretch over days or weeks.

The article describes how modern adversaries use the time between alarms to conduct recon, lateral movement, and data exfiltration, for example by querying a domain controller via LDAP at a careful pace, issuing Kerberos service ticket requests to obtain offline credentials, and then moving laterally through SMB or RDP sessions. Each step leverages ordinary business operations, so the activity only stands out when events are correlated across time and across systems.

The piece emphasises the role of network telemetry and NDR in revealing these sequences, arguing that context is created by linking multiple signals rather than isolating them. It highlights that AI is both a tool for attackers—speeding reconnaissance and payload execution—and for defenders when applied with detailed network evidence to surface relationships across hosts, users, protocols, and timelines.

The article explains how a single endpoint alert can be misleading unless extended by network context that answers what happened earlier, who participated, and how the activity evolved. It concludes by describing how AI-assisted SOCs can search broadly and reconstruct longer attack chains, enabling analysts to prioritise investigations with greater confidence. The report attributes these insights to Corelight’s emphasis on protocol-aware, evidence-backed network data.
