Day 5 of 7 Β Β·Β 71% complete
β Legal Notice β Defensive Awareness Only
Todayβs content describes documented criminal attacks so defenders can recognise and prevent them. Do not attempt to replicate any technique. Deepfake fraud, romance scams, and non-consensual intimate imagery are serious criminal offences under fraud, defamation, and NCII-specific laws in most jurisdictions. If youβre targeted: contact your bank immediately for financial fraud; file a police report; for intimate content contact NCII Alliance at stopncii.org. Report AI fraud to your national fraud body β IC3.gov in the US, Action Fraud in the UK, Scamwatch in Australia.
Let me start todayβs class with a case that sounds almost impossible β until you understand how the technology works.
In 2025, a 67-year-old woman in Arizona lost $340,000 in retirement savings to a romance scam. The person she believed she had met online was presented as a real man with a face, a voice, a career, a family, and a future he supposedly wanted to build with her. But the person on the other side of those conversations did not exist as she understood him to.
For months, she video-called the person she believed she knew. What she was seeing and hearing could be generated or manipulated using AI. Think about that for a moment. This wasnβt a suspicious email that she could simply delete. She had spent months building a relationship with someone she believed was real.
This is where deepfake attacks fraud become different from the scams we traditionally learn about. The technology isnβt just being used to create a fake photograph. It can be combined with social engineering, publicly available information, voice cloning, fabricated identities, and carefully timed conversations to create something much more convincing: a believable relationship with a completely false person.
Now, as we do in a classroom, letβs slow the story down and take the attack apart.
Before the victim is contacted, there is usually preparation. The attacker may research the target and collect information from public sources. Then comes the creation stage, where images, voices, videos, or an entire fictional identity can be assembled. After that comes delivery β the phone call, video meeting, dating profile, message, or social-media interaction. Finally comes exploitation: the moment the attacker tries to obtain money, credentials, sensitive information, access, or another form of control.
Thatβs the deepfake attack chain weβre going to study today.
Notice something important: you already learned pieces of this process in Days 2 through 4. You learned how to examine AI-generated faces, how to analyse suspicious video, and how to recognise clues in cloned voices. Today weβre going to connect those individual detection skills to the bigger picture.
Iβll show you the major forms of deepfake attacks fraud, walk through documented real-world cases, and then break an attack into its individual stages so you can see where the warning signs appear. Weβll look at CEO fraud, romance scams, identity fraud, political manipulation, and non-consensual deepfake content β not to teach you how to carry out these attacks, but to teach you how to recognise them.
And hereβs your assignment for today: donβt just study the examples on this page. Look at your own digital footprint. What photos of you are publicly available? What videos contain your voice? What information about your job, family, location, or relationships could a stranger collect without ever contacting you?
That information may seem harmless when you look at each piece separately. An attacker sees something different: raw material.
By the end of todayβs lesson, I want you to be able to look at a suspicious interaction and ask the right question: βWhere am I in the attack chain?β
Because recognising the attack early β before trust turns into money, access, or sensitive information β is the skill weβre building today.
