Bengaluru: Chinese computer and smartphone firm Lenovo Group Ltd said its website was hacked on Wednesday, its second security blemish days after the US government advised consumers to remove software called “Superfish” pre-installed on its laptops. Hacking group Lizard Squad claimed credit for the attacks on microblogging service Twitter. Lenovo said attackers breached the domain name system associated with Lenovo and redirected visitors to lenovo.com to another address, while also intercepting internal company emails. Lizard Squad posted an email exchange between Lenovo employees discussing Superfish. The software was at the centre of public uproar in the United States last week when security researchers said they found it allowed hackers to impersonate banking websites and steal users’ credit card information.
