For the second time in two years, the contents of the darknet payment card marketplace Swarmshop have been removed and posted to a competing underground forum, Group-IB reports. The content includes data on more than 600,000 payment cards as well as administrator, seller and buyer information.
Group-IB suspects the theft was conducted by some of Swarmshop's users.
"Although the source remains unknown, it must be one of those revenge hacks cases," Group-IB says in a report issued Thursday. "This is a major reputation hit for the illicit card shop as all the sellers lost their goods and personal data. The card shop is unlikely to restore its status."
