A recent system hack targeting a Twitter employee has led to a major data breach at the micro-blogging site.
Twitter co-founder Biz Stone said on Wednesday that the breach exposed a number of internal documents, but that no information regarding account credentials for the Twitter service itself was compromised.
The incident began in May when a French hacker known as 'Hacker Croll' broke into the email account of a Twitter executive, and gained access to a number of documents through the company's Google Apps account.
Earlier this week, the hacker began releasing the documents to a number of news outlets. The items reportedly include information from company meetings, plans for a television programme and details on the security systems at Twitter's headquarters.
Stone assured Twitter users in a blog post that no account information was among the stolen data.
"It's important to note that the stolen documents which where downloaded and offered to various blogs and publications are not Twitter user accounts, nor were any user accounts compromised except for a screenshot of one person's account and we contacted that person and recommended changing their password," he wrote.
"This was not a hack on the Twitter service. It was a personal attack followed by the theft of private company documents."
