One Prompt, One Like: How a Public Honor Became a Target Package

At Sentinel, we approach online risk assessments the same way a threat actor would. Recently, our in-house analytic team leveraged generative AI to demonstrate how an online troll can quickly become a capable threat actor. While this may be an executive protection team’s nightmare, it does not have to be.

Being recognized by your peers is good for careers and good for business. Awards lists, women in leadership designations, and board announcements celebrate the people who drive an organization forward. They also hand anyone with an internet connection a curated, verified list of senior decisionmakers, complete with titles, employers and cities.

To understand how easily that information can be turned against the people it celebrates, our intelligence team ran a simple exercise: think like a threat actor, use only free public tools, and see how far a few hours of curiosity can go. The answer was further than most executives would be comfortable with. Starting from a single AI prompt, the exercise ended with a senior executive's family photos, relatives' names and a recent personal loss, without touching a breached database or the dark web.

THE BOTTOM LINE

Your executives' threat surface is not defined by what they post. It is defined by what everyone around them posts, what the industry publishes about them, and what AI can now stitch together in minutes. The organizations that see that surface first, and shrink it continuously, are the ones that stay ahead of the people mapping it.

KNOW WHO IS LOOKING

Not every person who talks about your executives is dangerous. A useful way to sort them is by focus (the individual, the company, or both) and by at least two measures: risk (the likelihood they can reach the target) and impact (the damage if they succeed).

Company-focused actors run into corporate security controls, which lowers their odds, but a successful intrusion is costly. The concern this exercise highlights is mobility. With the right tools, an actor can move from the low-risk, low-impact corner into the high-risk, high-impact one quickly, and AI is now one of those tools.

That shift rarely announces itself. The account posting insults today may be compiling names tomorrow, and the difference is often visible only to teams watching consistently over time rather than reacting to a single alarming post.

INSIDE THE EXERCISE

The exercise began where many trolls begin: on social media. The results were a mix of leads, accounts worth a closer look and observations about who might be an easier target. Much of it was routine online hostility that may never go further.

A follow-up prompt produced a list of executives. The breadcrumbs didn’t stop there, Sentinel’s analyst dug deeper asking narrower questions until the result was a ready-made target list.

Asking about one person on that list produced information that led to even more granular details until finally the analyst surfaced a solitary like on a Facebook page that revealed the individual’s personal profile and ultimately intimate details about the individual’s personal life.

What stands out is not any single answer but the speed. Work that once took an afternoon of searching, cross-referencing and dead ends took a handful of prompts. The assistant did more than retrieve information; it organized it, suggested next steps and lowered the skill needed to act on it. For a troll, the first couple of prompts may be as far as curiosity goes. For a motivated actor, the same tool is a research assistant that never tires.

The executive never posted anything careless. The exposure came from professional recognition that resulted in personal exposure.

WHAT WAS EXPOSED

From one personal profile, the analyst found the executive's photo, spouse's name, an image of a grandchild, a stepchild, in-laws and evidence of a recent loss of someone close, including a reasonable indication of how that person died. Each detail is innocuous on its own. Together they give a threat actor what they need for several distinct attacks:

• Impersonation. Enough personal and professional context to pose convincingly as the executive to colleagues, vendors or family.
• Coercion. Named family members who could be threatened to pressure the executive into acting.
• Social engineering. Believable calls or texts.
• Targeted phishing. Lures aimed at both personal and work email. A recent bereavement opens an especially cruel vector: fake memorial pages and charity or donation links.

None of this required technical skill, paid tools or stolen data. What it required was patience, and generative AI is steadily reducing how much patience is needed.

WHAT SECURITY LEADERS SHOULD DO

The objective is simple to state and harder to execute, shrink the threat surface before someone else maps it. Work with Sentinel on these five steps to make the biggest difference.

Connect physical and cyber security. This case moved from an industry award to family exposure to a phishing vector. It crossed both domains, so CSO and CISO teams need to share what they see.

Assess the exposure. Complete an Online Risk Assessment alongside a Physical Security Risk Assessment. Determine whether executive or family personal information is exposed, what social media activity exists and whether a pattern of life can be discerned.

Monitor continuously. Use intelligence to detect hostile trends and narratives, identify newly exposed personal information for removal and catch breach data before it is exploited.

Remove PII from Data Broker Sites. Reduce the threat surface with continuous monitoring and removal of personally identifiable data of your executives and those in their inner circle.

Extend diligence and awareness. Screen incoming executives, board members and other high-profile partners, including a social media review. Brief executives and their families on how honors, board roles and personal posts connect, especially after major life events.
