Twitter warns users of official state-sponsored hack attack

Twitter issued an alert to some users warning them that state-sponsored hackers may have tried to obtain sensitive data from their accounts, the company said, the first such warning by the micro blogging site.

The notice said there was no indication the hackers obtained sensitive information from what it said were a “small group of accounts” targeted.

It did not provide additional information about the attack or its suspects.

Twitter’s notice is the latest amid concern about cyber attacks by state-sponsored organisations.

One organisation that said it received the notice, a Winnipeg-based nonprofit called Coldhak, said the warning from Twitter came on Friday.

The notice said the attackers may have been trying to obtain information such as “email addresses, IP addresses, and/or phone numbers”.

Coldhak (@coldhakca) retweeted reports from a number of other users who said they received the notice.

Coldhak and the other users did not indicate why they may have been singled out.

Colin Childs, one of the founding directors of Coldhak, told Reuters his organisation has seen “no noticeable impact of this attack”.

Google and Facebook have also started issuing warnings to users possibly targeted by state-sponsored attacks.
