Artificial Intelligence agents are easily susceptible to takeover attempts
In a groundbreaking revelation, cybersecurity firm Zenity Labs has unveiled a set of critical vulnerabilities named AgentFlayer affecting AI agents from major tech companies such as Microsoft, Google, OpenAI, Salesforce, and more. These vulnerabilities enable zero-click exploit chains, allowing attackers to silently hijack AI agents without any user interaction[1][4].
Key findings from Zenity Labs' research include:
- OpenAI's ChatGPT can be compromised via email-based prompt injections, granting hackers access to connected Google Drive accounts.
- Microsoft's Copilot Studio and Microsoft 365 Copilot agents were shown to leak entire CRM databases and be manipulated into social engineering attacks.
- Salesforce's Einstein platform could be manipulated to reroute customer communications to attacker-controlled email accounts, risking login information theft.
- Google's Gemini is also susceptible to manipulation targeting users with social engineering.
- AI developer tools like Cursor (integrated with Jira through MCP) are vulnerable to zero-click attacks that exfiltrate secrets from repositories or local files[1][2][4].
These attacks are particularly dangerous because they:
- Require no user action (zero-click).
- Can persist in memory, enabling silent, long-term hijacking.
- Allow attackers to impersonate users and manipulate critical workflows autonomously.
- Exploit vulnerabilities through indirect prompt injections and malicious payloads embedded in seemingly innocent documents or emails[1][4].
Following disclosure, affected companies like Microsoft, OpenAI, Salesforce, and Google responded by issuing patches and strengthening layered defenses against prompt injection attacks[3]. Microsoft emphasized ongoing platform improvements and built-in safeguards in Copilot agents. OpenAI maintained its bug bounty program and confirmed patching ChatGPT. Google highlighted its deployment of layered defense strategies against these vulnerabilities[3].
The research signals a fundamental shift in AI security, highlighting the urgent need for robust guardrails and comprehensive security measures tailored for interconnected AI ecosystems in enterprise settings. It underscores the significant risk posed by integrating AI agents with external systems, which expands the attack surface and introduces new vectors for exploitation[1][3][4].
Zenity Labs also offers a security platform for AI agents designed to provide adaptive security, governance, and observability to prevent such agent-based threats proactively[5].
Itay Ravia, head of Aim Labs, stated that Zenity Labs' results show a concerning lack of safeguards in the fast-growing AI ecosystem[2]. The responsibility for managing the high risk of such attacks is placed on companies, according to Ravia.
Recently, Google published a blog post about AI system protections[6], and a Google spokesperson emphasized the importance of a layered defense strategy against prompt injection attacks. Researchers from Aim Labs have demonstrated zero-click risks involving Microsoft Copilot earlier this year[2].
During a presentation at the Black Hat USA cybersecurity conference, Zenity researchers demonstrated how hackers could exfiltrate data, manipulate critical workflows, and even impersonate users[7]. The findings serve as a stark reminder of the evolving threats in the AI landscape and the need for continuous vigilance and robust security measures.

- The critical vulnerabilities discovered by Zenity Labs, called AgentFlayer, pose a significant risk to privacy in the modern enterprise setting, as they can be exploited to access connected Google Drive accounts, manipulate critical workflows, and exfiltrate sensitive data from AI agents.
- Cybersecurity company Zenity Labs' findings regarding AgentFlayer have accentuated the need for robust artificial-intelligence (AI) security, as the vulnerabilities can be exploited through indirect prompt injections and malicious payloads embedded in seemingly innocent documents or emails, necessitating comprehensive security measures tailored for AI ecosystems.
