Last week, the Twitter account of Twitter founder and CEO Jack Dorsey was hijacked by an unknown hacker who then used it to post offensive racial slurs and bomb threats.
The Twitter boss account which has over four million followers was used to send series of erratic and offensive messages, and as well suggestions about a bomb.
Some of the tweets contained the hashtag #ChucklingSquad, which seemed to be reference to the hacker group behind the account takeover.
This same hacker group has been responsible over recent hacks of high profile social media personalities. The account also retweeted a message supporting Nazi Germany.
According to the San Francisco-Internet based firm, the phone number associated with Mr. Dorsey's account was "compromised due to a security oversight by the mobile provider."
"This allowed an unauthorized person to compose and sent tweets via text message from the phone number," Twitter added.
Twitter said that the account was secured and that there was "no indication that Twitter's systems have been compromised."

The hackers directed anyone reading the tweets to a discussion board which was quickly taken down. Though the hackers didn't give their reason for the hack, they however ask Mr. Dorsey to remove the suspensions of a number of accounts.
Pinned atop Dorsey's account was a tweet from early last year which read" "We're committing Twitter to help increase the collective health, openness, and civility of public conversation, and to hold ourselves publicly accountable towards progress."
However, it took Twitter about a half an hour before they removed the non-friendly tweets from Mr. Dorsey's account.
The complete takeover of the Twitter boss account raised many questions regarding users privacy and safety on the platform, since they couldn't keep their bosses account safe from hackers.
"if you can't protect, you can't project... jack," One Twitter said.
Cybersecurity researcher Kevin Beaumont said the account seemed to have been hijacked via a third party called Cloudhopper, a service that allows users to send tweets on their phone via SMS.
Cloudhopper which Twitter acquired about 10 years ago, had access to Mr. Dorsey's account.
