Mandiant: ShinyHunters Exploit SSO and Vishing Campaigns
🔒 Mandiant reports a recent wave of ShinyHunters attacks that combine targeted vishing and company‑branded phishing sites to capture SSO credentials and MFA codes. Attackers impersonate IT or helpdesk staff, guide victims through MFA approval or one‑time passcodes in real time, and enroll attacker-controlled MFA devices. With access to Okta, Microsoft Entra, or Google SSO dashboards they pivot into SaaS platforms (Salesforce, Microsoft 365, SharePoint, DocuSign, Slack, Atlassian, Dropbox, Google Drive) to steal and extort cloud data.
