Crypto Call Scams Rise in France Following Data Leaks, Hasheur Says

French crypto entrepreneur Owen Simonin, known online as Hasheur, has warned of an increase in fraudulent phone calls targeting cryptocurrency users. According to Simonin, scammers are impersonating customer service representatives from crypto platforms and contacting users whose information may have been exposed in recent data leaks.

Scammers Impersonate Crypto Platform Support Staff

The reported scams involve threat actors posing as representatives of cryptocurrency companies. By presenting themselves as customer service agents, the callers may attempt to gain the trust of victims and obtain sensitive information or access to their accounts.

Simonin said the number of these calls has increased recently, linking the trend to data leaks that affected French crypto users. Exposed contact details can make fraudulent calls appear more credible because the scammers may already possess basic information about their targets.

Data Leaks Increase the Risk of Targeted Fraud

Data breaches do not necessarily provide direct access to cryptocurrency holdings, but leaked personal information can be used to support phishing attempts, impersonation schemes and other forms of social engineering.

Crypto users are frequently targeted because transactions can be difficult to reverse once funds have been transferred. Users should be cautious when receiving unsolicited calls about account security, withdrawals or suspicious activity, particularly when the caller requests passwords, authentication codes or transfers of cryptocurrency.

Users Urged to Verify Support Requests

Customer service representatives should not require users to disclose private keys, seed phrases or one-time authentication codes. Any support request received by phone should be independently verified through the platform’s official website or application rather than through contact details provided by the caller.

Simonin’s warning highlights the potential consequences of data leaks beyond the initial exposure of personal information, as criminals may use leaked details to make subsequent fraud attempts more convincing.
