Whatever encryption for CCs, I think its going to have to be reversible or there wont be any point of storing them.

- orblivion 15y agoUnless they keep the keys somewhere unrelated?
- jasonlotito 15y agoThe keys generally aren't kept anywhere. In fact, the encryption keys for a company valve's size should be split among multiple key company officials. The idea being, you should be able to steal the box that contains the credit card data and/or the machine that does the actual encryption and not have access to the keys (which, technically, aren't stored anywhere).
- rapind 15y agoOne technique is to store another string (a pepper) outside of the database (assuming the salt is stored with the records) which is used along with the salt to encrypt each password. This way, if only the database is compromised, and not the config file or env variable holding the pepper you're in better shape.
- jaequery 15y agoif they got to the database!, what makes you think they didn't get to the app server?
- awj 15y agoThis could be the result of sql injection or some other application-level attack.
- stickfigure 15y agoOr possibly just a lost backup tape.
- mguillemot 15y agoIf some backup tapes might go out of the building, they'd better be encrypted...
- pferde 15y agoI certainly DO hope that some backup tapes go out of the building. Offsite backups are a good thing.
- lawnchair_larry 15y agoAlthough they theoretically could have, a lot of these hacks are done via SQL Injection, which is a step below having direct access to the machines. You can often leverage SQL injection further to do just that, but it takes more work/luck/skill than just dumping the DB. So it's not a given that they got filesystem access, but we shouldn't assume that they didn't either.
