In a tweet Wednesday night, the company said it is looking into what information the attackers "may have accessed" and will share that information as it becomes available.
US Senator Josh Hawley sent a notice to Twitter chief Jack Dorsey, asking him to work with the Federal Bureau of Investigation and the DOJ to secure the platform. It's something we've seen happen during elections and breaking news events.
In the interview, Dorsey emphasized the importance of gaining the trust of users and advertisers, which may be in disarray given that the accounts of major brands and high-profile tech and political leaders were compromised.
Investors appeared troubled by the potential fallout of the hack on Twitter usage.
Congressman Frank Pallone, the chairman of the House energy and commerce committee, called on the company to account for what went wrong.
Most if not all these accounts were Twitter verified, and between them they shared tens of millions of followers.

Nevada County isn't on the monitoring list , though it is still affected by the statewide closure of bars and indoor dining. The order comes after Newsom previously ordered these businesses to close in counties on the state's "watch list".
The platform suffered the largest hack in its history on Wednesday after numerous high-profile accounts were compromised and used to promote a bitcoin scam.
In a statement, Twitter stated, users "may be unable to tweet or reset your password while we review and address this incident".
The hack took place just after 4 p.m.
Twitter's stock was down $1.15 (3.22 percent) to $34.52 per share in overnight trading Thursday. "While it still isn't clear if the hackers behind yesterday's incident gained access to Twitter direct messages, this is a vulnerability that has lasted for far too long, and one that is not present in other, competing platforms". In the case of billionaire Tesla Chief Executive Elon Musk, for example, one tweet soliciting cryptocurrency was removed and, sometime later, another one appeared, and then a third. U.S. President Donald Trump, for example, regularly uses Twitter to post about national and geopolitical matters, and his account is closely followed by media, analysts and governments around the world. Several accounts of cryptocurrency-focused organizations were also hijacked.
Biden's campaign was "in touch" with Twitter, according to a person familiar with the matter.
"Could have easily sold this access for millions", David Kennedy, the creator of two large-scale cybersecurity firms, wrote on Twitter. Other methods include installing technical tools to monitor for suspicious insider activities and reducing the number of people who have access to an administrative panel, Tobac said.
