Ransomware: AI changes the writer. It doesn't change the math.

This whitepaper explains the growing threat of remote encryption ransomware—where an unmanaged or remote machine encrypts files on a protected server without a local malicious process—and argues that process-centric EDR is architecturally unable to stop such attacks. It describes Sophos CryptoGuard’s file-system–level, content-based detection and rollback mechanism as a long-standing defense that detects ciphertext patterns rather than relying on signatures or AI models, and highlights real-world impacts and statistics showing the prevalence and speed of remote ransomware.
