Sao Paulo • A massive cybercrime ring in Brazil may have stolen billions of dollars from a widely used online payment system, a technology security company said.
The RSA Security division of EMC Corp. said in a research report released on Wednesday that a "malware-based fraud ring" had infiltrated the online payment method known as the boleto, diverting payments to accounts held by members of the ring.
Boletos are used in a wide range of transactions, such as telephone, school tuition, mortgage and credit card payments.
The report said the scheme may have compromised close to 500,000 transactions with an estimated value of $3.75 billion over a two-year period. However, researchers were unable to determine how many of those boletos were paid by victims or whether they went to fraudster-controlled bank accounts."
