British Airways and Ticketmaster hacks are the work of the same group
According to an analysis by security company RiskIQ, the same group is behind the hacks on British Airways and Ticketmaster. It would be the so-called Magecart group, which focuses on payment data and other sensitive information.
The company lays the link between the two incidents in a analysis of the scripts on the British Airways site. Normally the company receives a notification when a Magecart script appears on a site that is blacklisted, but in this case it was a modified variant. By examining the changes on the site, RiskIQ found out that on August 21 of this year an update was made in the Modernizr library for JavaScript on the British Airways page for baggage claims. The script was supplemented with 22 lines of code, which made it possible to steal entered data, according to the security company.
