eBay have had a security issue, in which the database containing "eBay customers’ name, encrypted password, email address, physical address, phone number and date of birth" was hacked into via someone at eBay's internal login that had the appropriate permissions, and the contents acquired.
Here we go again. You know the drill:
- change your eBay password to something new
- if you use the same password anywhere else, change it to something different
- consider using a secure password manager like 1Password if you can't remember passwords
- be vigilant about attempts at identity theft - the hackers got away with your name/address/DoB
Identity and authentication are a key part of today's Internet. Don't treat them lightly.
