If an attacker uses a valid account and connects through a nearby residential IP address, would your systems recognize the activity as unusual?
QTFY’s infrastructure was designed to conceal malicious traffic and blend it with legitimate activity. That makes basic blocking less effective and increases the importance of good logs and behavior-based monitoring.
Security teams need evidence from more than one place. Firewall traffic, VPN access, identity events, endpoint activity, cloud applications, email, and critical servers can each show part of the story. When those logs are retained and reviewed together, unusual combinations become easier to recognize.
Examples include an administrator logging in from a new device, a service account used interactively, remote access at an unusual time, new software installed after an appliance alert, or a large data transfer following a successful login.
The absence of an alert does not prove the absence of an incident. First confirm that the right systems are producing useful logs—and that someone or something is actually watching them.
