Advanced Cybersecurity & Threat Landscape
Deepfakes, Social Engineering, and BEC
Business email compromise now uses voice clones and deepfake video to authorize wire transfers and credential resets, and the weakest link is usually a process that trusts a single human's approval. Defenses combine technical controls with out-of-band verification for any money or access change. Training helps, but process design is what actually stops the fraud.
핵심 내용
- Require out-of-band verification for any payment, vendor change, or privileged access request, using a known phone number, not the one in the email.
- Enforce dual approval for wire transfers above a threshold and for new payee setup.
- Flag first-time or unusual payment instructions and hold them for manual review.
- Train staff on voice and video cloning and on the specific phrases attackers use to create urgency.
- Lock down email with DMARC, DKIM, and SPF, plus mailbox rules that auto-forward or hide messages.
- Monitor for lookalike domains and impersonation of executives and vendors.
- Restrict who can change payment details and require a ticket with an audit trail.
- Run simulated BEC exercises that include phone and video, not just phishing emails.
자주 묻는 질문
Can deepfakes really fool finance teams?
Yes. Cloned executive voices and short video clips have already authorized real transfers, which is why process controls matter more than detection.
Is email training enough?
No. Training reduces clicks; out-of-band verification and dual approval are what stop the money from leaving.
What is the simplest effective control?
A callback to a known number for any request that moves money or grants access, with no exceptions.
How do we detect a compromised mailbox?
Watch for new forwarding rules, unusual login locations, and sent items the user did not send.
