[SAN FRANCISCO] Twitter Inc said some of its accounts were locked to prevent potential disclosures from hacks of other websites that may have leaked login credentials on the internet.
Users whose accounts may be vulnerable were notified and told they must reset their passwords to gain access to the social messaging service, Twitter said Thursday in a blog post from Michael Coates, trust and information security officer.
"In each of the recent password disclosures, we cross-checked the data with our records," Mr Coates said in the post. "As a result, a number of Twitter accounts were identified for extra protection."
In the post, Mr Coates said the company is "confident the information was not obtained from a hack of Twitter's servers."
