Cyber attackers increasingly exploit familiar tools such as PowerShell, RDP, backup utilities and cloud sync apps for data exfiltration, bypassing traditional signature-based detection methods that focus on prohibited software. These attackers leverage trusted resources, blending into standard IT operations and evading conventional security measures.
To counter this, a behavioural detection approach is recommended—one that tracks anomalous patterns such as unusual file access, unexpected network spikes, or out-of-hours cloud activity. Security teams should move beyond basic application inventories, prioritising the identification of data movement anomalies across endpoints, networks and cloud infrastructure. Adapting both technology and mindset away from tool-based detection towards behavioural analysis is vital for robust defence in today’s threat landscape.
