Hackers escalate attacks on social networks
Security breaches at LinkedIn and eHarmony have highlighted an escalation in attacks on social networks from hackers seeking to exploit personal data, according to security firms.
The professional networking and dating sites have both confirmed that some of their users’ passwords have been stolen, after hackers posted a total of 8 million encrypted passwords online, 6.5 million of them from LinkedIn, the company said. LastFM, a UK-based social music site owned by CBS, said it was investigating a potential leak of its users’ passwords. Like LinkedIn and eHarmony, it advised users to change passwords. Experts said the LinkedIn hack was one of the largest yet seen and a sign that cybercriminals are showing an increasing preference for targeting social networks over email.
