Pattaya, Thailand – August 26, 2025 – IntroSecurity ASEAN today issued a cautionary advisory highlighting significant cybersecurity risks uncovered in OpenAI’s newly released ChatGPT-5 model. While GPT-5 demonstrates powerful advances in natural language processing and agent-based automation, recent independent testing has revealed multiple vulnerabilities that enterprises must not ignore.
Critical Risks Identified
Security researchers and independent labs have flagged the following weaknesses in GPT-5 and its ecosystem:
-
High Susceptibility to Jailbreaks and Prompt Injection: GPT-5 failed nearly 90% of controlled adversarial tests, making it prone to manipulation through crafted prompts. This raises the likelihood of sensitive data leakage, policy bypass, and model misuse.
-
Routing Vulnerability: Due to architectural design flaws, some queries are processed by weaker, outdated models rather than GPT-5 itself. This inconsistency creates exploitable blind spots.
-
Zero-Click Exfiltration Attacks: When GPT-5 is integrated with external platforms (such as Google Drive, Jira, or email), maliciously crafted documents can trigger automated data exfiltration without any user action.
-
CAPTCHA Bypass by Autonomous Agents: GPT-5-powered agents have successfully circumvented human verification tests, raising risks of fraud, large-scale spam, and credential abuse.
-
Ecosystem Abuse through Fake Apps: Malware campaigns, such as the newly discovered PipeMagic backdoor, are being distributed under the guise of “ChatGPT desktop apps,” targeting IT, finance, and real estate sectors.
Implications for ASEAN Enterprises
Karl DiMascio, Co-Founder of IntroSecurity ASEAN, commented:
“The release of GPT-5 represents both an opportunity and a threat. Its expanded capabilities can drive efficiency and innovation, but its security posture has not kept pace. In ASEAN, where digital adoption is accelerating and regulatory oversight is tightening, organisations must assume that GPT-5 can be exploited unless rigorous guardrails and monitoring are in place.”
IntroSecurity ASEAN emphasizes that the risks are not theoretical. The ability of GPT-5 to bypass controls and interact autonomously with business systems dramatically increases the attack surface. Adversaries are already experimenting with ways to weaponize these vulnerabilities at scale.
Recommendations from IntroSecurity ASEAN
To mitigate risks, IntroSecurity ASEAN advises:
-
Deploying isolation layers between GPT-5 and core business systems.
-
Conducting continuous adversarial testing to detect injection and routing anomalies.
-
Enforcing strict integration governance for third-party applications.
-
Training staff to recognize social engineering attempts amplified by AI.
-
Monitoring for fake ChatGPT applications to prevent malware infiltration.
