Deepfake Detection

Deepfake detection literacy names synthetic media signals, verification habits, and fraud context — defender skills on YOUR $AI_LAB notes, not deepfake fraud kits.

Deepfake detection literacy. $AI_LAB only. Original Cyberlium.

Seeing is not believing — literacy names deepfake detection so you verify high-risk media, not build fraud impersonation kits.

Deepfakes synthesize face, voice, or video to impersonate executives, family, or public figures — used in fraud, disinformation, and extortion. Detection signals: lip-sync mismatch, unnatural blinking, audio spectral artifacts, metadata gaps, and out-of-band verification. Defender fix: callback policies, multi-factor approval for wire transfers, and media forensics tools — literacy only; NO deepfake fraud kit building on Cyberlium. Cyberlium writes deepfake detection card on YOUR $AI_LAB — analyze labeled courseware clips or fictional indicators on paper. Next: AI Malware Named.

1. Deepfake detection signals (named)

Visual: lip-sync drift, lighting inconsistency, edge artifacts around face. Audio: robotic cadence, missing breath sounds, clone mismatch on uncommon words. Process: verify via second channel — call back on known number, not callback number in message.

On $AI_LAB, write detection checklist — five signals and one out-of-band verification step for fictional exec-voice scenario.

Command guide

Try these commands — Deepfake detection signals (named)

═══ LINUX / macOS (Terminal Practice) ═══

Check system state and user context

Command — copy this

id
whoami
uname -a

Inspect network sockets listening for connections

Command — copy this

ss -tuln 2>/dev/null || netstat -tuln

Audit active processes

Command — copy this

ps aux | grep -v "\[" | head -15

═══ WINDOWS (POWERSHELL) ═══ Query user identity and system information

Command — copy this

whoami /all
Get-ComputerInfo | Select-Object CsName, OsName, OsVersion

Primary tools to practice this lesson: grep, python3. Reference sites: CISA deepfake guidance (https://www.cisa.gov/ai); NIST AI RMF (https://www.nist.gov/itl/ai-risk-management-framework); MITRE ATLAS (https://atlas.mitre.org/). Run every command in the box — install first, then the usage lines — only on YOUR lab / program scope.

2. Why verification policy beats pixel hunting alone

Detection ML arms race continues — organizations enforce 'no wire transfer from voice note alone' and executive callback lists. Analysts document indicators for awareness training with redacted fictional media — not live fraud deployment.

Students refuse deepfake fraud kit tutorials — detection and policy literacy only.

3. Literacy ≠ deepfake fraud kits

Forbidden: building voice-clone fraud kits, impersonating real executives for transfer requests, or distributing synthetic media of real people without consent. Allowed: deepfake detection card — signals, verification policy, fictional scenario on $AI_LAB.

Ship: deepfake detection card for YOUR lab notes. Next: AI Malware Named.

4. What you ship: deepfake detection card for $AI_LAB

Five signals, verification policy, fictional scenario. $AI_LAB named. NO fraud kits. chmod 600.

5. What you record before the next lesson

Date. Deepfake detection card. $AI_LAB named. File t32-m05-l02-deepfake-detection.txt chmod 600.

6. Wrong vs right: stranger SaaS vs YOUR toy LLM

Worked failure — same MSF word, opposite target. Right never needs a café Wi-Fi or classmate laptop.

Wrong: Build voice-clone kit to call real finance team. Skip out-of-band verification in policy notes.
Right: Write deepfake detection card for YOUR $AI_LAB. Next: AI Malware Named.
