A former senior financial crime investigator at Binance told IRS investigators in May that Binance management had ignored internal requests to investigate approximately 2,000 suspected Iran-linked accounts involving $1.2 billion in transactions, Forbes reported. Citing a search warrant for the investigator’s MacBook, the report said the DOJ and IRS had issued multiple subpoenas and search warrants involving Binance and former employees, with one former investigator also ordered to testify before a federal grand jury. Binance denied firing employees for investigating potential sanctions violations, saying they left over breaches of customer data privacy policies. The exchange said it is cooperating with law enforcement. No criminal charges have been filed.
