Analysis
Wrench Attacks on the Rise in France
France is already the epicenter of wrench attacks, where investors are targeted and forced to hand over their crypto. The French tax authority has been hacked, and 678,438 records have been leaked. Among the individuals, an estimated 26,805 have a reported annual taxable income of €100,000 or more, 386 exceed €1 million, and eight exceed €10 million.
The exposed sample reportedly includes highly sensitive information: full legal names, dates and places of birth, home and mailing addresses, marital status, number of dependents, internal tax identification numbers, reference taxable income, individual withholding tax rates, phone numbers, email addresses, and records of past correspondence with tax officials.
Security analysts warn that this combination of identity, contact, and financial data could fuel highly convincing phishing campaigns impersonating tax authorities, as well as identity theft and fraud schemes tailored to victims' income levels or family circumstances.
Wrench Attacks on the Rise Globally
2025 was the worst on record for wrench attacks, with around 55 reported globally last year, according to TRM Labs. Lopp's tool counted over 70 throughout last year. And this year is already looking bad, according to the tracker: 54 attacks have been documented so far.
