A new social engineering campaign is targeting cybersecurity firms with fraudulent OpenAI organization invitations that impersonate legitimate companies. The attackers create rogue OpenAI tenants mimicking trusted organizations, then send invites to employees in an apparent bid to extract sensitive corporate information.

According to BleepingComputer, the scheme exploits trust in collaboration platforms. Employees who accept the invites are prompted to join chat projects and workspaces where they may inadvertently submit confidential data, including network configurations or client details. The scope of affected organizations remains unclear, but the targeting of cybersecurity firms suggests a deliberate effort to gain insider knowledge.

Technical details are still emerging, but the attack relies on social engineering rather than exploiting a software vulnerability. Indicators of compromise include unsolicited OpenAI tenant invitations from unfamiliar domains or slight misspellings of known company names. No CVE has been assigned, as this is an abuse of platform functionality rather than a flaw.

Mitigation recommendations include verifying any unexpected organization invitations through out-of-band communication with the purported sender. OpenAI has not yet issued a public statement on the campaign. Firms are advised to review their tenant settings and restrict external invite permissions where possible.

Attribution is not yet confirmed, but the campaign's focus on cybersecurity firms aligns with prior espionage operations seeking to infiltrate defense-oriented technology companies. The broader trend of abusing trusted SaaS platforms for phishing continues to grow.
