This week in family office risk

Three security developments worth a family's attention:

1. Four jailed in France over a crypto-investor kidnapping.

Prosecutors in Mulhouse charged four people over the May abduction of a 25-year-old who had spoken about his cryptocurrency investments. He was held, threatened and pressured into transfers totaling roughly €14,000 before being released. It was the third crypto-linked kidnapping in the Alsace region in recent months.

2. A law firm's breach went unnoticed for ten months.

A Manhattan firm whose work includes trusts and estates disclosed, in a filing with the Maine attorney general, that intruders were inside its network for roughly ten months before anyone noticed, from the middle of 2025 until this spring. Those affected were offered a year of credit monitoring, and the filing wasn't clear on how many people were exposed.

3. Authorities and tech giants disrupted 1.4 million fraud-linked accounts.

In a novel operation, the Justice Department said, U.S. authorities joined Apple, Google, Microsoft, Meta, Coinbase and others to disrupt more than 1.4 million accounts tied to Southeast Asian investment-fraud networks. The group froze more than $3.8 million in cryptocurrency, and police in Thailand arrested seven.
