Home Depot says that in addition to 56 million payment cards, the attackers 
responsible for the breach on their POS network earlier this year also 
compromised 53 million email addresses.

Thursday's breach investigation update also said the attackers leveraged a 
third-party vendor's username and password in order to access the network.

Home Depot said the vendor's credentials were not enough to access the POS 
network directly, so the attackers needed to elevate their access. Using a 
zero-day vulnerability in Windows, they did just that, and maintained their 
presence on Home Depot's network for five months.

The retailer has stated previously that they believe the malware used in the 
attack was active on their POS network between April and September of 2014.
