Arrests are expected to be announced Wednesday after cyberthieves hacked into more than 1,000 accounts on online ticket retailer StubHub and fraudulently bought tickets. According to police officials, the case crossed international borders, and a joint announcement Wednesday will include officials from the U.S., U.K., and Canada. According to StubHub, the hackers didn’t get through the company’s security, but instead got the information from other retailers’ websites or from malware on customers’ computers. The company caught the transactions last year, gave refunds, and contacted the government. StubHub is owned by eBay, which also had its own hacking incident recently.
