Twitter has been hit with a minor data breach incident that the social networking site believes linked to a suspected state-sponsored attack.
In a blog post published on Monday, Twitter revealed that while investigating a vulnerability affecting one of its support forms, the company discovered evidence of the bug being misused to access and steal users’ exposed information.
The impacted support form in question was used by account holders to contact Twitter about issues with their account.
So far the company has declined to provide more details about the incident or an estimate for the number of accounts potentially impacted but says it believes that the attack may have ties to state-sponsored actors.
“During our investigation, we noticed some unusual activity involving the affected customer support form API. Specifically, we observed a large number of inquiries coming from individual IP addresses located in China and Saudi Arabia,” Twitter says in a post about the incident.
“While we cannot confirm intent or attribution for certain, it is possible that some of these IP addresses may have ties to state-sponsored actors.”
Twitter also assures its users that the issue does not expose full phone numbers or any other personal data related to the user.
Twitter says that the social networking site addressed the issue within just one day on November 16 and that there is no action required from the users’ side.
Twitter has started directly notifying the users who, according to the company, have been impacted by the incident.
“We have directly informed the people we identified as being affected,” the company writes. “We are providing this broader notice as it is possible that other account holders we cannot identify were potentially impacted.”
