Tesco’s Twitter account seems to have fallen into the wrong hands, and the company is currently in the process of restoring the profile to its previous condition. The hacker started retweeting Bill Gates and even impersonating him on the account. The attacker then started replying to complaining Tesco customers asking for private details such as full name, home address and postcode, purportedly to fix things. Tesco is a British multinational with more than 6,800 shops across the world, serving customers in countries including the U.S. and India.
