San Francisco, CA, United States (4E) – Microblogging site Twitter has been hacked affecting accounts of 250,000 users and prompting the online social networking site to ask Tweeters to reset their passwords.
Hackers accessed user names and e-mail addresses of Twitter users by exploiting a Java vulnerability, according to Twitter’s blog post on Friday.
Twitter’s director of information security, Bob Lord, said in the blog that a hacking incident that was discovered and immediately warded off was actually a large-scale cyberattack. Lord said the hacking was the work of sophisticated hackers.
Affected users cannot log in to their accounts until they have reset their passwords as instructed through e-mail. Session tokens were also revoked.
The hacking of Twitter, which has 200 million users, comes after The New York Times, Washington Post and Bloomberg News admitted being targets of suspected Chinese hackers.
