In 2018, a single WhatsApp message breached the private phone of the world’s richest person. There was no break-in with ski masks. No server farm hack from across the globe. It was a social connection exploited through a tiny app on a phone.
Within days, personal data that should have been utterly confidential was splashed across global news. The fallout was immediate: reputation damage, shareholder concerns, and a very public lesson in what happens when digital and physical security aren’t integrated.
Experts later confirmed the attack could have been identified earlier if the target’s digital and physical security teams had been operating as one system rather than in separate silos.
That was seven years ago. The tools available to adversaries have only gotten more powerful, more accessible, and more difficult to detect.
What OSINT Actually Is
Open-Source Intelligence — OSINT — is the collection and analysis of information from publicly available sources. It requires no hacking, no insider access, and no illegal activity. Everything used is legally accessible.
The sources include social media platforms, public records databases, data broker sites, corporate filings, news archives, court records, property records, satellite imagery, professional networking sites, and the metadata embedded in photos, documents, and communications.
In 2026, OSINT has become the primary intelligence-gathering method for a wide range of adversaries: journalists investigating stories, litigants building cases, activists targeting executives, private investigators working for opposing parties, and organized criminal groups planning operations against high-net-worth targets.
The reason OSINT is so effective is that most people — including most wealthy and prominent individuals — don’t realize how much information they’re making publicly available.
How Adversaries Build a Targeting Package
An adversary targeting a UHNW individual or their family doesn’t start with the individual. They start with the periphery.
Staff social media accounts are the first source. A personal assistant’s LinkedIn profile lists the family office name, the location, and their job title. A housekeeper’s Facebook account includes check-ins at the estate’s nearest grocery store, revealing the property’s general location. A driver’s Instagram shows photos of luxury vehicles — some with license plates visible.
Family member social media is the second source. A spouse’s Instagram reveals travel destinations, interior photos of the residence, the children’s schools, and social connections. A teenager’s TikTok shows the layout of the family home. A college-age child’s public Venmo transactions reveal spending patterns and frequent locations.
Public records provide the infrastructure. Property records reveal the home address, property layout, and purchase price. Vehicle registrations identify vehicles. Business filings reveal corporate structure. Court records may reveal legal disputes, financial information, or custody arrangements. Political donation records reveal affiliations and ideological positioning.
Data brokers aggregate everything. Names, addresses, phone numbers, email addresses, estimated net worth, family relationships, and more — assembled into a comprehensive profile available for under $20.
In most cases, an adversary can build a detailed targeting package on a UHNW family in 48 to 72 hours using nothing but OSINT. They’ll know where the family lives, what they drive, where the children go to school, what the spouse’s daily routine looks like, who the household staff are, and what the estate’s security posture looks like from the outside.
Real-World OSINT Exploitation
The applications of OSINT targeting are varied and increasing.
Physical crime planning: burglary crews have used Instagram posts, Google Earth imagery, and real estate listing photos to map the interior layouts of high-value properties before breaking in. The 2016 Paris robbery of a prominent public figure was planned almost entirely using social media intelligence — the attackers knew the target’s location, the timing, and the value of what was in the room because it had all been posted publicly.
Executive targeting by activists: advocacy groups have used data broker records to map the home addresses of corporate executives and organize protests at their residences. This tactic has been used against pharmaceutical executives, fossil fuel company leaders, and technology company officers.
Litigation intelligence: in high-net-worth divorce proceedings and shareholder disputes, opposing counsel hires investigation firms that specialize in OSINT collection. Everything from spending patterns inferred from social media to property ownership revealed through public records to communications metadata obtained through legal discovery gets assembled into a narrative.
Kidnapping and extortion planning: organized criminal groups in Latin America, West Africa, and Southeast Asia use OSINT to identify and assess potential targets among wealthy families. Travel patterns, property locations, school schedules, and family member identities are all collected before any physical surveillance begins.
Corporate espionage: competitors and state actors use OSINT to map an executive’s professional network, identify potential intelligence sources within their organization, and develop social engineering approaches based on the executive’s known interests, affiliations, and communication style.
The AI Amplification Problem
In 2026, artificial intelligence has dramatically amplified the effectiveness of OSINT operations.
AI-powered tools can now aggregate, cross-reference, and analyze open-source data at a speed and scale that was impossible even three years ago. What used to require a team of analysts working for weeks can now be accomplished by a single person with access to commercially available AI tools in a matter of hours.
Facial recognition technology can identify individuals across social media platforms and public cameras. Natural language processing can scan thousands of documents, social media posts, and news articles to build comprehensive profiles. Predictive analytics can identify patterns in movement data and forecast likely future behavior.
Deepfake technology adds another dimension: AI-generated video and audio can now impersonate any public figure convincingly enough to manipulate staff, markets, or public opinion. A fabricated video of an executive making inflammatory statements can be distributed widely before the executive’s team even knows it exists.
How to Reduce Your OSINT Exposure
Reducing OSINT exposure doesn’t mean disappearing from the internet. It means understanding exactly what’s publicly available about you and your family, and making deliberate decisions about what remains visible.
Start with a comprehensive OSINT audit — the same kind of intelligence collection an adversary would conduct, but done by your own team. Map everything that’s publicly findable: social media, data brokers, public records, dark web mentions, corporate filings, news archives, image search results.
Implement data broker removal across all family members. This is an ongoing process, not a one-time action. Data reappears. New brokers emerge. Continuous monitoring and removal is required.
Establish social media policies for the entire household — family members, staff, and extended support personnel. These policies should cover geotagging, location sharing, photography of the property and family, and any mention of the family office, the principal, or security arrangements.
Audit property ownership and corporate structures for unnecessary public exposure. In some cases, restructuring ownership to use trusts or corporate entities can reduce the amount of personal information appearing in public records.
And integrate OSINT awareness into your broader security operations. When your digital privacy team discovers that a data broker has your new address, your estate security team needs to know. When social media monitoring detects someone posting about your family’s travel plans, your travel security detail needs to adjust.
Digital exposure doesn’t stay digital. Every piece of information that’s publicly available about you is a potential input to a physical threat. Managing that exposure isn’t a privacy project. It’s a security operation.
