Valve continues without making an official statement on this matter.
It seems that everything is back to normal Steam after movidita later that at times has frightened thousands of users of this digital distribution platform. The reason? Fear that have been filtered data bank accounts because of an error which, they say, is related to the cache servers.
This situation has allowed some users to view the personal information of other fans, knowing for example your home address, telephone number or the last four digits of your credit card. It seems, however, that aggregate data have been stolen as mentioned at the beginning of this situation.
So far Valve has not issued an official statement explaining what has happened exactly, but a member of the Steam community itself has made clear that the platform "has not been blocked."
The important thing right now is that Steam reenters operation, and no errors are detected.
