The internet already has what they need
Most organizations, and most people, publish far more than they realize. A LinkedIn profile lists a job title and reporting structure. A company website names who handles which accounts. A press release announces a deal before it closes. None of this is a security failure exactly, it's how modern business operates, but it's also a complete research library for anyone building a convincing impersonation.
What attackers are actually looking for
Three things matter most: who has the authority to approve or send a payment, what a normal, plausible request looks like for that organization, and what's currently happening that would make an urgent request believable. A closing date, a funding round, a vendor relationship, any of these gives an attacker the specific, timely detail that makes a fraudulent message feel routine instead of suspicious.
Executives are especially exposed
Senior leaders are disproportionately targeted because their authority makes requests bearing their name hard to question, and because their voices and faces are extensively documented in public settings: earnings calls, conference talks, interviews, investor presentations. That same documentation is what makes voice and video cloning possible with minimal effort.
This is why "the email looked right" isn't reassuring
When an attacker has done real research, the email will look right. The names, the timeline, the tone, all of it can be built from public material. Judging legitimacy by how accurate the details are misses the point; accuracy is exactly what thorough reconnaissance produces.
What actually resists this kind of research
No amount of public information gives an attacker someone's biometric identity or the ability to pass as the actual account holder of a specific bank account. That's the distinction between information that can be gathered and identity that has to be verified directly, which is the layer research alone can't fake.
- Can a company really prevent this kind of research?
- Not entirely. Some information, staff names, transaction timing, is necessary to publish for normal business. The more reliable defense is assuming attackers have done their homework and verifying identity independently regardless.
- Does removing information from LinkedIn or a website help?
- It can reduce the surface area somewhat, but it isn't a complete solution on its own, since attackers combine multiple public sources rather than relying on any single one.
