“Twitter said Friday it has patched a bug that could have shared users’ private messages with software developers outside of the company. The issue is estimated to have impacted less than 1 percent of Twitter’s total user base, which includes 335 million monthly active users as of July. The company has hundreds of partner developers. The company’s stock price hit a day low of $28.49 following the bug’s disclosure. Twitter’s share price closed at $28.50, down more than 4.5 percent on the day. ‘We have no evidence to suggest that any data was improperly misused or exploited anywhere,’ a company spokeswoman told CNBC, emphasizing that the bug could only occur if a series of complex criteria were met. ‘There’s virtually no possibility that this happened, but we still want to be thorough.'”
