"...accounts had been compromised for over a month, between January 21, 2012 and February 25, 2012.
JPMorgan Chase & Co, as well as American Express and Discover, which issue their own cards, said they are monitoring customers' accounts and would issue new cards to anyone whose information may have been compromised."
In early Feb someone used my Discovercard to charge $2100 at Best Buy. Charge was reversed and they issued a new card. Wonder if it was a part of this. The Discover people certainly never mentioned it as a possibility.
