I emailed the Equifax hackers at the email posted on their darknet site and they responded with the following:

We are processing information is not a single file and we must still

unite which data correspond to which people. We are not going to give interviews. We do not have expectations to collect anything so that on the 15th

everything will be published except the credit cards. 09/15 at 4pm UTC —

Оборудование для взлома

Note the Russian signature, loosely translated by Google translate to: “Equipment for hacking”. A quick google search says the name may have to do with Wardriving – an old technique for picking up insecure wifi for mobile roaming wifi. It is rather presumptuous to say they’re a Russian hacking group, but the Russian signature does raise an eyebrow.

The email is signed with their PGP signature.
