Living Off the Land (LOTL) attacks are the silent architects of modern breaches. This presentation dissects how attackers leverage legitimate tools to evade detection, from ransomware to APTs. We'll explore the "shades of gray" these attacks create, and shifting security focus from blocking malicious to analyzing suspicious. We'll examine why LOTL thrives, its various forms, and practical defense strategies. All backed up by our analysis of telemetry data and incident investigations by Bitdefender Labs.
