If you’re one of these 4.6 million brokerage customers, you just got hacked...

Online broker Scottrade just revealed computer hackers compromised 4.6 million customers’ records.

The data include Social Security numbers, email addresses, and physical addresses.

CNNMoney reports the hack affects anyone who signed up with the broker before February 2014.

Scottrade is now offering all clients one free year of identity-protection services.

Pay particular attention to any email you receive claiming to come from Scottrade. It may have the Scottrade logo and other identifiers... but if it’s not from a recognized address, don’t open it. Contact Scottrade if you have any doubts.
