Attackers are bypassing traditional cybersecurity defenses and exploiting overlooked security weaknesses and vulnerabilities, according to CrowdStrike’s 2025 Threat Hunting Report (Report). They are also working patiently to establish footholds, moving slowly and stealthily over time, making detection more difficult. Moreover, generative AI is helping attackers craft more convincing social engineering ploys and support their attacks in other ways. This article synthesizes the key takeaways from the Report and the additional insights offered in a related Crowdstrike webinar.
