Hackers Could Bypass ChatGPT Lockdown Mode to Steal Conversations Without Users Knowing
ChatGPT Lockdown Mode bypassed by researchers, allowing data leaks and malware delivery.
Check Point Research discovered a vulnerability in ChatGPT's Lockdown Mode that allowed attackers to bypass security measures. The flaw could be exploited to steal entire chat histories, display fake update windows to trick users into downloading malware, and capture login credentials. OpenAI has since patched the vulnerability.

The lesson from this incident
Full lessonCheck Point Research uncovered a vulnerability in ChatGPT's Lockdown Mode that fundamentally undermined a security feature users trusted to protect their data. Attackers could exploit this flaw to silently exfiltrate entire conversation histories, serve convincing fake update prompts to deliver malware, and harvest login credentials — all without the user's knowledge. The incident highlights a dangerous gap between perceived security (a named 'Lockdown Mode') and actual security guarantees. It matters because users placed elevated trust in a named security feature, amplifying the potential harm when that feature failed. OpenAI's subsequent patch demonstrates that even purpose-built security controls require rigorous, ongoing vulnerability testing.
What helps against this
How we list vendors
- Endpoint detection and response (EDR and XDR)
Malware and hands-on-keyboard attackers on laptops and servers get spotted and stopped.
- AI application security
Prompt injection, data leaks through AI tools and unapproved AI use get caught.
- Security awareness training and phishing simulation
People recognise and report attacks instead of falling for them.
