Digital Parasites Keep Ransomware Inside Networks Longer, Extending Dwell Time

Picus Security’s Red Report, cited by The Hacker News, reveals a tactical evolution from flash‑in‑the‑pan ransomware strikes to “digital parasite” operations. Instead of encrypting files immediately, adversaries embed stealthy footholds, linger for weeks or months, and slowly siphon data while subtly manipulating systems. This covert presence lets them gather valuable intelligence, stage secondary attacks, and demand higher ransoms backed by proven exfiltration.

The extended dwell time dramatically raises risk for organizations: more data can be stolen, attackers can map the environment more thoroughly, and the eventual ransomware payload is often more destructive. Defenders must shift from purely signature‑based detection to continuous threat hunting, tighter network segmentation, and robust data‑exfiltration monitoring. Reducing the window of undetected activity is now as critical as blocking the final encryption event.
