• Shares of Okta dropped more than 7% Tuesday following reports of a data breach. 
  • A group called LAPSUS$ posted what it claimed to be photos of Okta's internal servers. 
  • Okta's CEO took to Twitter and said there was no evidence of any ongoing malicious activity. 

Okta stock dropped Tuesday after a group of hackers claimed an illegal data breach at the digital authentication company.

The hackers, reportedly representing an organization known as LAPSUS$, posted a photo of Okta's internal server in its Telegram channel, per Reuters. 

But the photos instead may be connected to a hack attempt from January that has since been resolved, according to Okta CEO Todd McKinnon. 

In a tweet, he said there was no evidence of any ongoing malicious activity following a data breach. 

 

He said Tuesday that in January it had "detected an attempt to compromise the account of a third party customer support engineer working for one of our subprocessors," but nothing came of it.

Okta, which has more than 15,000 customers worldwide including T-Mobile and Peloton, facilitates secure management of systems and websites. 

Shares were down about 7% in premarket trading Tuesday and have lost about about 25% so far this year through Monday's close.

LAPSUS$, meanwhile, has also said it was responsible for data breaches at Samsung and Nvidia in recent months.
