"In late January 2022, Okta detected an attempt to compromise the account of a third party customer support engineer working for one of our subprocessors," McKinnon tweeted. "The matter was investigated and contained by the subprocessor." In a statement sent to The Verge, Chris Hollis, Okta spokesperson, said Okta has not found evidence of an ongoing cyberattack or data breach. "Based on our investigation to date, there is no evidence of ongoing malicious activity beyond the activity detected in January," Hollis said. Okta customers must be on high alert right now, security experts say.
