Microsoft is the latest in a long line of high-profile organisations to be targeted by internet hackers, although this attack came from a group calling itself Evil Shadow Team, rather than Anonymous who are arguably the world’s most well-known ’hacktivists’.

The attack was aimed at Microsoft India’s online store, which had to close as a result of Evil Shadow Team‘s actions. The hackers reportedly were able to steal login IDs and passwords of people who’d used the site for purchasing Microsoft products. Following the attack, reports said that screen shots of customers’ details were posted on the site before Microsoft took it offline, saying they were “investigating a limited compromise.”

However, a person claiming to be one of the hackers contacted Reuters to say that they had found unencrypted customer data on the site. Microsoft wouldn’t confirm whether or not the data was encrypted, simply stating that “We are diligently working to remedy the issue and keep our customers protected.”

An apology on the website also offered little by way of an explanation, with a message that said “The Microsoft Store India is currently unavailable. Microsoft is working to restore access as quickly as possible.”

While the group that is taking responsibility for the attack calls itself Evil Shadow Group, when the online store was hacked, a picture of the Guy Fawkes mask appeared, something that is usually associated with the hacker group Anonymous.
