--Japanese Online Supermarket Database Hacked (August 15, 2010) Attackers reportedly used SQL injection attacks to steal customer information from the databases of eight Japanese online supermarkets.
The attacks took place in late July 2010. Some credit card companies have reported fraudulent activity on accounts compromised in the attacks.
