The company said attackers obtained basic business contact information, internal CRM records and limited back-office documents, and that no sensitive customer data beyond basic business details was compromised. Optimizely said the attackers could not escalate privileges, install software or create backdoors.","how_it_worked":"Attackers phoned Optimizely employees while impersonating IT support and used a helpdesk pretext to manipulate them into disclosing their credentials and reading back multi-factor authentication codes. With a valid authenticated session, the intruders reached the company's CRM and internal document stores and pulled business contact records and back-office material. The access was constrained: Optimizely said the attackers were unable to raise privileges, deploy software, or establish persistence, so the incident ended as data theft plus extortion pressure rather than a deeper compromise.","lessons":"Phishing-resistant MFA plus a hard rule that IT never asks for codes by phone would have made the credential handover valueless.","confidence":"Confirmed","sources":[{"title":"Ad tech firm Optimizely confirms data breach after vishing attack","url":"https://www.bleepingcomputer.com/news/security/ad-tech-firm-optimizely-confirms-data-breach-after-vishing-attack/","publisher":"BleepingComputer"}],"entry_type":"incident","slug":"2026-optimizely-confirms-data-breach-after-vishing-attack-on-employees","year":2026,"loss_kind":null,"url":"https://global-social-engineering-impact-da.vercel.app/incidents/2026-optimizely-confirms-data-breach-after-vishing-attack-on-employees"}}
