UPDATE: Seven people from around the world have been arrested in connection with the StubHub hacking case, which resulted in more than $1.6 million in event tickets being stolen.
According to USA Today, authorities still do not know exactly how the cyber thieves gained access to the accounts.
Three people were arrested in London, two in the New York area, and one in Spain. Authorities say that the suspects resold the tickets and worked with several people to launder the money using international wire transfers and PayPal.
Arrests are expected to be announced today in the case of more than 1,000 StubHub customer accounts that were hacked last year.
The cyber thieves used the accounts to purchase tickets through the online ticket re-seller. Officials with the company say arrests are being made across international borders.
A press conference was held Wednesday in New York with London and Royal Canadian Mounted Police officials, according to CBS Washington.
The San Francisco-based StubHub says the thieves did not break through its security. Rather, the thieves were able to get the customers' log-ins and passwords through other websites and retailers or from key-loggers or other malware on the customers' own computers.
StubHub refunded money to all of the customers who were affected.
StubHub is owned by eBay. It is the leading online seller of concert, sports, theater and other tickets. It offers brokers and fans a way "to buy or sell their tickets in a safe, convenient and highly reliable environment," according to their website.
Other companies such as Target, LinkedIn, eBay and Neiman Marcus have also been victims of cyber thieves within the past year.
