Snapchat, the disappearing-message service popular with young people, has been quiet following a security breach that allowed hackers to collect the usernames and phone numbers of millions of its users.
Snapchat said today that it is assessing the situation, but did not have further comment.
Earlier this week, hackers reportedly published 4.6 million Snapchat usernames and phone numbers on a website called snapchatdb.info, which has since been suspended. The breach came less than a week after security experts alerted Snapchat of a vulnerability and warned that such an attack could take place.
In response to the warning, Snapchat said in a blog post last Friday that it had implemented "various safeguards" over the past year that would make it more difficult to steal large sets of phone numbers. But the measures appear to have fallen short.
