Attackers Hide in the Quiet Gaps Between Your Security Alerts

Security teams are buried in alerts, but very few of them explain how an attack began or how it progressed. According to the source article, an intrusion often first appears as a handful of separate, smaller events: a known piece of malware is matched, failed logins spike, or software on a device flags suspicious behaviour. Viewed on a dashboard, these can look unrelated even when they belong to the same attack.

The article notes that artificial intelligence has made attacks faster, helping criminals automate reconnaissance, craft targeted payloads and run scripts in seconds. But speed does not remove the need for stealth. To avoid detection, adversaries deliberately slow down, hide inside standard administration tools, and work in the quiet intervals between alarms. They may spend days or weeks in an environment before anything triggers a high-priority alert, which means that alert may not mark the start of the compromise at all.

Attackers also understand how stretched security teams are. If every DNS query, directory lookup, file-sharing connection or login attempt prompted an investigation, queues would become unmanageable, and attackers rely on that. The article argues that network data, such as that from a network detection and response (NDR) platform, can connect individual alerts into a single timeline. Investigating only the event that triggered an alert risks missing the chained activity that explains the whole intrusion.
