The Quiet Target: Why Family Offices Get Hit — and What Actually Stops It

Family offices sit in an unusual spot. They manage extraordinary wealth — often hundreds of millions, sometimes billions — with lean teams, informal processes, and a culture built on trust and discretion. Every one of those traits is a strength for running the office. Every one is also something an attacker can use.

Banks and institutional managers have spent decades hardening under regulatory pressure. A lot of family offices never had that forcing function, so they stayed quiet and assumed quiet meant safe. It doesn't anymore. Deloitte's 2024 Family Office Cybersecurity Report found that 43% of family offices worldwide had been hit by a cyberattack in the previous 12 to 24 months — and a quarter had been hit three or more times. In the same study, 31% had no incident response plan at all, and 68% had no process for vetting the vendors they hand access to.

Here's the honest version: you don't need the security apparatus of a global bank. But you can no longer count on obscurity to do the job for you.

Why family offices get targeted

A few things line up to make family offices worth an attacker's time.

Bank-sized value, consumer-sized defenses. A successful breach can pay out like an attack on a mid-sized institution — without the mid-sized institution's security team behind it.

Small teams wearing every hat. A five-person office may have no dedicated IT, let alone a security lead. The person approving wires is often the same person picking the office's software.

A culture of trust. Discretion and loyalty are exactly the traits social engineers are trained to exploit.

Public principals. Travel, philanthropy, business dealings, family details — much of it is easy to research, and all of it is raw material for a targeted attack.

No clean perimeter. The work reaches into residences, household staff, personal devices, and private travel. The attack surface runs far past a corporate firewall.

That last point is the one most offices underestimate. As we put it on our managed cybersecurity page, attackers don't start with your hardest target. They start with email, passwords, and forgotten access — the everyday systems nobody's watching.

Where the risk actually shows up

1. Business email compromise and wire fraud

This is the one that empties accounts. An attacker compromises or spoofs an email — a principal, an advisor, an attorney, a familiar vendor — and asks for an urgent transfer. Family offices move large sums, often on short notice. A fraudulent request doesn't stand out in that traffic; it blends right in. The FBI's Internet Crime Complaint Center tallied $3.05 billion in reported BEC losses in 2025, one of the single costliest categories of cybercrime it tracks — and those are only the losses victims reported.

What it usually looks like:

• A "time-sensitive" investment wire that appears to come from the family principal.
• A compromised attorney's account sending updated escrow instructions before a real estate closing.
• A familiar vendor's invoice — same name, same logo, new banking details.

Attackers are patient here. They'll sit inside an inbox for weeks, learn how the office talks and pays, wait for a real deal to land, and slip the fake instructions in at exactly the right moment.

2. Spear phishing and whaling

Generic phishing is easy to spot. Phishing built specifically for your office is not. Attackers pull from public records, social media, data-broker sites, and old breach data, then write messages that reference real deals, real people, real events. Executive assistants and controllers get hit most, because they control access and payments.

3. Ransomware and data extortion

Family offices hold the kind of information that makes extortion easy: estate plans, tax returns, trust documents, prenuptial agreements, medical records, the private mechanics of a family. Increasingly, the threat isn't just locking your files — it's threatening to publish them. Verizon's 2025 Data Breach Investigations Report found ransomware present in 44% of breaches, up sharply from the year before, and most of those attacks now involve stealing the data before anything gets encrypted. For a family that values privacy above almost everything, that's the real leverage. And paying buys you nothing you can enforce.

4. Insider risk

Malicious or accidental, insiders matter. Household staff, personal assistants, and departing employees often carry broad access. Small offices tend to be light on segregation of duties, background checks, and offboarding discipline — which is how access outlives the reason it was granted.

5. Third parties and vendors

Family offices run on a web of outside parties: wealth managers, banks, law firms, accountants, art advisors, yacht crews, staffing agencies, property managers. Every one is a possible entry point. A compromised vendor with trusted email access to your office is a classic way in — and often the one that gets traced after the money's gone. In the 2025 Verizon report, the share of breaches involving a third party doubled year over year, to roughly 30%. Set against Deloitte's finding that 68% of family offices don't formally vet their vendors, that's a gap worth closing.

6. The office has no fixed walls

A family office rarely runs from one hardened building. The same work happens at a residence, on a plane, at a second home, on a personal phone, and on a laptop the principal also uses for personal email. The device that approves a wire on Monday is the device booking travel and checking personal accounts on Tuesday.

That blurring is the exposure. When personal and office systems share the same devices, logins, and connections, a compromise on the personal side doesn't stay there — it lands one click from the accounts that move money. Most offices manage the "office" environment reasonably well and never draw a line around everything else the work actually touches.

7. Where digital risk becomes physical

For high-net-worth families, cyber and physical risk are the same risk. Travel itineraries, alarm-system access, staff schedules, and children's locations are all just data. Geotagged photos, property records, and flight tracking can feed anything from a burglary to something far worse.

8. What's already public about you

An enormous amount is legally available: home addresses, property records, political donations, court filings, family relationships. Attackers use that open-source intelligence to build a convincing pretext — and to answer the "security questions" that are supposed to protect your accounts. Regulation here is uneven and shifting: the federal Consumer Financial Protection Bureau withdrew its proposed data-broker rule in May 2025, while California's Delete Act moved the other direction. As of January 2026 residents can file a single deletion request through the state's DROP platform, and registered data brokers must begin honoring those requests on August 1, 2026. Useful — but a patchwork you can't rely on to protect a family by itself.

What actually stops it

None of this requires a global bank's budget. It requires owning a handful of controls and keeping them current. Here's where we'd start.

Decide who owns security

Someone has to be accountable — even if the work is outsourced. The most common gap we see isn't a missing tool. It's that nobody owns the whole picture, so the details fall through the cracks: an unmonitored inbox, an old vendor login, a backup nobody's ever tested. Assign the ownership first. Then get an independent risk assessment so you're working from what's actually exposed, not what someone assumes is fine.

Lock down wires (non-negotiable)

• Verify out of band. Confirm every wire — and every change of banking details — by phone, to a number you already had on file. Never the number in the email.
• Require two approvers above a set threshold.
• Build in a cooling-off period for new payees or changed instructions.
• Write the callback procedure down and drill it until it's reflexive.

Get identity right

• Enforce MFA on everything — email, banking, cloud storage, accounting. App-based or hardware keys, not SMS where it counts.
• Use a password manager so nothing gets reused.
• Give people the least access their role needs, and nothing more.
• Kill access the day someone leaves.

Protect email and devices

• Advanced email filtering with anti-impersonation.
• DMARC, SPF, and DKIM so nobody can spoof your domain.
• Managed endpoint detection on every device that touches office systems.
• Patch promptly and retire software that's no longer supported.

Draw a line between personal and office

• Give principals and key staff hardened, managed devices for office and financial work — kept separate from the personal phones and laptops used for everything else.
• Keep office accounts, email, and files off personal devices, and personal accounts off the office ones.
• Where the work happens outside a managed office, put office traffic through a trusted, encrypted path so it never depends on whatever network the principal happens to be on.
• Separate the networks the work rides on — office systems shouldn't share a lane with guest access and personal devices.

Manage vendors like they can reach you — because they can

• Vet a vendor's security before you hand over access or data.
• Put security requirements in the contract.
• Limit and monitor what each vendor can touch.
• Treat any vendor email changing payment details as suspect until you've verified it by phone.

Train the people attackers actually target

• Run role-specific awareness training — including principals, who are the most targeted and often the least trained.
• Run simulated phishing.
• Train household staff and assistants; they're frequent entry points.
• Build a culture where questioning an odd request — even from the boss — earns thanks, not a reprimand.

Have a plan before you need one

• Keep a written incident response plan with real names and escalation paths.
• Keep offline, tested backups of critical records.
• Line up an incident response firm and legal counsel before the emergency.
• Know your bank's fraud-reporting window cold. With a fraudulent wire, hours decide whether you get the money back.

Shrink your public footprint

• Audit what's publicly available about the family.
• Use data-broker removal services — and, for California residents, the state's new DROP deletion request.
• Coach family members on social media, location sharing, and oversharing.
• Structure property ownership and public filings to reduce personal attribution where you can.

A word on cyber insurance

A well-built policy can cover wire fraud, incident response, and extortion. And insurers increasingly require baseline controls as a condition of coverage. As of 2025–2026, underwriters commonly want enforced MFA on email and remote access, endpoint detection across all devices, and immutable backups with proof you've actually tested a restore — no evidence, no bind, or a much thinner policy. That makes a good policy two things at once: a financial backstop, and a useful push to get the fundamentals done.

The next generation is part of your attack surface

A lot of offices are handing wealth to a generation of digital natives with large online footprints. Extend the education and the controls to younger family members. Their social feeds and personal devices can expose the whole enterprise.

Where Droptine stands

We don't lead with fear, and we don't lead with tools. Buying software isn't the same as being secure — a firewall here, antivirus there, a few "secure" portals in between, and still no one owning the big picture. Our approach for family offices is the same one we run everywhere: find the exposure, lock down what matters, and maintain the program. For an office, that means hardening wire-approval paths and identity across personal and office accounts, and reining in the advisors and vendors with standing access. Quietly, and in language you can repeat to the family or the board.

Security that was set up once and left alone is security that used to work. The controls above stop the large majority of real-world attacks — but only while someone keeps them current as the office, the family, and the vendor list change.

In an industry built on trust, the working rule is still trust, but verify. Especially by phone.
