CrowdStrike’s 2021 OverWatch Threat Hunting Report preview summarizes a year of record interactive intrusion activity from both eCrime and targeted intrusion adversaries between July 2020 and June 2021. OverWatch reported more than 65,000 potential intrusions identified by human hunters and behavioral preventions on roughly 248,000 unique endpoints, emphasizing adversary speed, lateral movement, and evasion of technology-only defenses. The source highlights case studies, common and emerging TTPs, telecom-sector growth, and defender recommendations rather than attributing the activity to a specific DPRK actor.
