A disturbing new trend is emerging from the shadows, highlighting a critical vulnerability in our digital-first world: the weaponization of sensitive personal data by insiders. A recent case in Bobigny, France, serves as a stark warning. There, a tax employee brazenly exploited internal government software to compile detailed dossiers on individuals, including high-net-worth cryptocurrency specialists, billionaire Vincent Bolloré, prison guards, and even a judge. This invaluable information was then sold to criminals, leading to violent home invasions, such as an attack on a prison officer in Montreuil for a mere €800 fee.
While the details of this particular case are chilling, its true significance lies not just in what transpired, but in how targets were identified. The threat landscape has evolved beyond mere digital hacks or Telegram doxxing. The newest, most insidious vector is the privileged access to state identity systems that can map names to addresses, phone numbers, and even family structures with a single, unauthorized query.
The "Uberization" of Identity Theft
French authorities are grappling with what the National Police Inspectorate (IGPN) has termed the "uberization" of file trafficking. This chilling description refers to the widespread, commoditized sale of government database lookups via social networks and the dark web. The IGPN reported a staggering 93 investigations in 2024 for violations of professional secrecy and another 76 for outright database diversion. These figures underscore the growing epidemic of insiders abusing their access for illicit gains.
A separate investigation by TF1, a major French television channel, uncovered a shocking "service menu" offered on platforms like Snapchat, detailing transparent pricing for illicit data access:
- €30 for a vehicle registration lookup
- €150 for a wanted-persons file check
- €250 for an illegal vehicle un-immobilization
Bank transfers linked to one suspect in these schemes reportedly ranged from €15 to €5,000, illustrating the low entry barrier and lucrative nature of this underground market.
Why Crypto Holders Are Prime Targets for Physical Coercion
Cryptocurrency’s security model is built on irreversibility and self-custody, aiming to eliminate the risks associated with traditional intermediaries like banks. However, this strength becomes a profound weakness once an attacker obtains a real-world identity. The "crypto part" then ceases to be a matter of cryptography and transforms into a far more dangerous problem of physical coercion.
Think of it as "IRL MEV" (In Real Life Maximal Extractable Value). Just as on-chain MEV exploits transactional flow, physical attackers extract value by first observing an individual's identity graph and then choosing the most effective and cheapest path to coercion. Crypto holders present an unusually favorable risk-return profile for these criminals:
- Self-Custody: Assets are held directly by the individual, meaning no bank freeze or court order can reverse a coerced transfer.
- High Value, Instant Mobility: Victims often possess significant digital wealth that can be moved instantly, making them attractive targets.
- Fear of Scrutiny: Reporting such crimes might expose victims to tax scrutiny they may have been actively avoiding, creating a disincentive to seek help.
France's Response and the Unintended Consequences
The escalating wave of attacks on crypto investors in France has prompted official recognition of the threat. Le Parisien reported in December that these incidents have multiplied, leading the French government to issue an August 2025 decree. This measure removed the home addresses of crypto business leaders from the RCS commercial registry, a publicly accessible corporate filing known as Kbis documents. While this aims to protect against physical aggression and harassment, law enforcement, customs, and tax administration agencies still retain full access to this sensitive data.
This policy change signals an institutional acknowledgment that crypto-related physical risks operate differently from traditional financial crimes. Banks can freeze accounts, and brokerage transfers can often be reversed. Crypto transfers, however, are final. This finality fundamentally shifts the threat landscape from technical security to identity security.
Despite these protective measures, new exposures are on the horizon. France's proposed 2026 budget includes a controversial 1% annual tax on crypto holdings exceeding €2 million, which would require self-custodied and offshore holdings to be declared. This policy inadvertently creates a "honeypot": a government-maintained list of high-net-worth crypto holders, complete with their personal addresses.
The Regulatory Paradox: Transparency Creating Vulnerabilities
A significant paradox underlies this escalating crisis. European authorities are simultaneously pushing for greater crypto transparency through mandatory Know Your Customer (KYC) regulations, wallet-provider reporting, and DeFi transaction tracking. While these efforts aim to combat money laundering and tax evasion, they also create increasingly comprehensive, centralized databases mapping identities to crypto holdings.
"The more comprehensive the database, the more valuable it becomes to attackers."
Tax systems, in particular, hold granular and continuously updated personal information: addresses change with returns, phone numbers appear on correspondence, family structures are revealed through dependent declarations, and capital gains filings map asset classes to individuals. The TF1 investigation confirmed that French tax databases give employees access to all this information, creating an irresistible target for criminal elements.
The unit economics strongly favor attackers: a data lookup costs mere tens to hundreds of euros, while a successful home invasion or coercion attempt can yield at least five or six figures. The European Union Agency for Cybersecurity (ENISA) tracked 586 incidents affecting EU public administrations in 2024. The threat model isn't sophisticated hacking, but rather insiders with legitimate credentials extracting data for secondary markets. Ghalia C., the Bobigny tax employee, admitted passing information to multiple attackers, and her search history extending to a wide range of high-value targets indicates she was systematically selling access, not pursuing a personal vendetta.
Beyond Technical Security: The Identity Layer Failure
Within the technical community, crypto security is often framed primarily as key management. While essential for on-chain attacks, the Bobigny case unequivocally demonstrates that key management becomes irrelevant once physical coercion enters the threat model. Seed phrases stored in hardware wallets offer no protection when attackers know your home address and arrive with weapons. The true security failure, in these scenarios, happens much further upstream: in the identity layer.
France’s police inspectorate’s "uberization" framing is alarmingly precise. Database lookups are indeed sold like commodities, with transparent pricing and a readily available market. Employees with legitimate access recognize the arbitrage opportunity: lookups cost them nothing, buyers pay significant sums, and the perceived risk of detection remains relatively low.
While France can prosecute individual cases, the underlying incentive structure remains intact. The RCS address suppression is a marginal improvement, but it does not address the thousands of government employees who possess legitimate access to a treasure trove of tax, law enforcement, and judicial databases containing everything an attacker needs. Crypto's promise of disintermediation – no banks, no gatekeepers, no trusted third parties – holds true for censorship resistance and seizure protection. Yet, this model utterly fails when the threat is physical coercion, directly enabled by compromised government identity systems.
The Bobigny case forces us to confront a market structure that typically operates in the shadows. Targets often remain unaware they have been "looked up" until the attackers are quite literally at their door. Addressing this fundamental vulnerability requires not just legal remedies, but a complete re-evaluation of how sensitive identity data is managed, secured, and accessed within governmental systems globally.
