The social network has warned some of its users of the chance for state-sponsored hackers accessing their data.

Twitter has now released an alert for some of the users of its social network, cautioning them of a certain online and mobile security issue that may have involved state-sponsored hackers attempting to access sensitive data from within their accounts.

This is the first time the company has issued this type of warning to any of its users.

Within the mobile security and online privacy notice, it indicated that as of that time, there had not been any indication that would suggest that the hackers had actually managed to access any of the sensitive information from within a “small group of accounts” that had been targeted during the attempts. That said, the letter didn’t provide any more information about the attack, nor did it suggest any potential suspects that were being sought as a part of the company’s investigation into this issue.

This mobile security and privacy notice is only the latest among several data breach concerns from state-sponsored organizations.

Mobile Security and TwitterTwitter is far from alone in the threat it has faced by way of cyberattacks. Many companies, government agencies and media outlets have all seen their fair share of data breaches from hackers. Several news sites have now been reporting on the warning that Twitter has issued. Among them, one was actually a recipient of the notice. It was a company called Coldhak, which is a nonprofit organization based in Winnipeg, Canada.

That company’s notice explained that the cyber attackers could potentially have been seeking to breach mobile security or online privacy barriers in order to gain access to information such as IP addresses, email addresses and/or telephone numbers. That organization’s own Twitter account (@coldhakca) has since retweeted a several reports from other people who have also claimed to have received the notification from Twitter.

Neither Coldhak nor any of the other users have given any indication as to why they may have been targeted for this type of cyberattack. One of the directors of the nonprofit, Colin Childs, said that despite having received the notice from Twitter, his organization has detected “no noticeable impact of this attack.” Facebook and Google have also issued their own versions of notifications to let users know when state-sponsored attacks have targeted their accounts.
