Hackers exploit vishing to bypass MFA at Okta - TechInformed
Hackers exploit vishing attacks to bypass MFA at Okta Security researchers have identified a sophisticated vishing (voice phishing) campaign targeting Okta users to bypass multi-factor authentication (MFA). Attackers use social engineering tactics to trick users into revealing MFA codes or credentials, circumventing traditional security controls. This attack vector highlights the vulnerability of MFA systems when combined with human manipulation. The campaign demonstrates that even organizations with strong technical security measures remain susceptible to social engineering attacks. Okta has acknowledged the threat and recommends users exercise caution with unsolicited communications and implement additional security awareness training to mitigate risks.
