Ransomware Keeps Your Hours
Halcyon's July ROC telemetry found that 69% of early-stage ransomware activity occurs during daytime hours, with actual encryption operations delayed until after business hours. Attackers appear to conduct reconnaissance and initial compromise phases while staff are present before deploying encryption when facilities are unattended.
Why it matters: Security teams need monitoring during standard business hours to catch ransomware reconnaissance and lateral movement before attackers return out-of-hours to encrypt systems.
