France investigates tax authority breach after hacker claims 600,000 victims
French authorities are investigating a breach of the tax authority's systems after a hacker claimed to have accessed data on 600,000 people. The intrusion, which occurred in late June, reportedly involved stolen or misused credentials.
Why this matters: Tax records are some of the most sensitive data a government holds. Income, assets, debts, dependents — it is a detailed financial portrait of your life. If 600,000 people's records were exposed, the damage is not just identity theft. It is the kind of personal financial detail that enables targeted fraud, coercion, and scams that are hard to trace back to the breach. The entry point here was apparently a stolen identity, which means one compromised credential opened the door to hundreds of thousands of people's private financial lives.
