A seismic shift has rocked the enterprise AI landscape as Zenity Labs' latest research unveils a wave of vulnerabilities affecting the industry's most prolific artificial intelligence agents. Ranging from OpenAI's ChatGPT to Microsoft's Copilot Studio and Salesforce’s Einstein, a swath of critical tools have been exposed to "0click" exploit chains that enable silent hijacking, data exfiltration, and autonomous workflow manipulation—none of which require any human interaction. This stark revelation, presented at Black Hat USA 2025, marks a new era of risk for organizations leveraging AI to drive productivity, illustrating that automated threats now move faster and further than most current security paradigms can track.
Artificial intelligence agents are fast becoming the digital backbone of modern enterprise operations, automating everything from customer service to internal knowledge management and code generation. Adoption rates have surged: ChatGPT now boasts 800 million weekly active users, and Microsoft 365 Copilot’s seats have skyrocketed tenfold within just 17 months. These numbers underscore the pervasiveness of AI in business—but as Zenity Labs shows, they also signal the emergence of a vast, underprotected attack surface.
Zenity’s findings should not be considered just incremental warnings. Rather, they represent a fundamental pivot in the security equation—one where attacks can be executed at scale and speed, bypassing human oversight entirely. This is more than an evolution of risks; it’s a revolution in how threat actors exploit enterprise AI.

However, the security landscape is far from uniform. Multiple vendors—including some providing critical enterprise AI infrastructure—declined to patch the identified vulnerabilities, citing them as "intended functionality" rather than flaws. This stance highlights a greater industry problem: the line between feature and exploit is often blurred in rapidly evolving AI solutions.
Yet this same power, when misdirected, can foster catastrophic risk:
Organizations must scale up not only their adoption of AI but also their vigilance and skepticism about how these systems work under the hood. This means treating AI agents as both a competitive asset and a risk vector of the highest order. Success in this new environment will be measured by how quickly the industry can shift from patchwork security to holistic, intent-aware defense for every piece of automated intelligence embedded within the enterprise.

Anatomy of the Attacks
0Click Exploit Chains: The New Frontline
Unlike traditional cyberattacks, which often require user action such as clicking malicious links or downloading rogue software, the vulnerabilities uncovered by Zenity revolve around "0click" exploits: fully automated sequences that require no user interaction.The researchers demonstrated that attackers can:
- Silently compromise AI agents embedded in enterprise workflows
- Exfiltrate sensitive business data without detection
- Manipulate automated workflows (from CRM updates to customer comms)
- Implant persistent malicious "memories" in AI systems
- Convert otherwise helpful AI tools into adversarial autonomous agents
Targeted Platforms and Attack Scenarios
OpenAI ChatGPT: Malicious Memories and Credential Theft
Zenity’s team engineered a prompt injection attack triggered by nothing more than a crafted email. This exploit gave attackers access to users’ connected services—most notably, Google Drive. Worse, it allowed adversaries to plant malicious histories and instructions inside ChatGPT’s memory, corrupting future sessions and potentially transforming the tool into a vector for ongoing attacks.Microsoft Copilot Studio: CRM Data Leakage
A campaign targeting Copilot Studio showed how AI-powered business logic could be subverted to leak entire CRM databases. Given that CRM data often holds a company’s most privileged information—customer contacts, proprietary agreements, ongoing deals—the implications for competitive espionage are immense.Salesforce Einstein: Workflow Subversion
Attackers used Salesforce’s Einstein agent to reroute all customer communications to attacker-controlled email addresses, simply by injecting malicious logic during a new case creation. This exploit would enable mass interception of customer data and sabotage of business processes.Google Gemini, Microsoft 365 Copilot: Social Engineering via AI
These agents were turned into sophisticated, persistent insiders—using poisoned emails and calendar invites to exfiltrate sensitive conversations, and even manipulating human targets through social engineering at a scale previously unattainable through manual phishing.Cursor with Jira MCP: Developer Credential Exfiltration
Zenity’s research did not stop at generic enterprise workflows. Tools like Cursor integrated with Jira MCP were conscripted to harvest developer credentials. Exploited ticket workflows became vehicles for credential theft, jeopardizing both codebases and project management systems crucial to software teams.The Mechanics Behind the Silent Takeover
Why AI Agents Are Uniquely Vulnerable
Enterprise AI agents typically enjoy broad access to critical systems and data. They utilize direct integrations with email, document storage, CRM tools, and internal communications to boost productivity—providing them with expansive, privileged access scopes.However, this access model creates unique risks:
- AI agents interpret and act on user prompts or automated triggers with little inherent skepticism or context checking
- Many operate independently, with limited audit trails or granular permission checks
- They can “learn” from past interactions, allowing malicious inputs to propagate over time
The Shift to Fully Automated Attacks
With 0click exploit chains, attackers can weaponize the basic features of AI agents—email parsing, case management, or file access—turning automation itself into the avenue of compromise. These attacks are harder to detect, as there are:- No suspicious attachments, links, or downloads
- No unusual user activity (since humans are not triggering the exploit)
- Minimal log events to differentiate normal automation from attacker-driven subversion
Industry Response: Patches, Pushback, and Persistent Gaps
Vendor Reactions and Responsible Disclosure
Following responsible disclosure by Zenity Labs, some vendors acted quickly: both OpenAI and Microsoft Copilot Studio reportedly issued patches addressing specific vulnerabilities outlined in the research. These patches closed immediate holes, particularly those making prompt injection and silent privilege escalation possible.However, the security landscape is far from uniform. Multiple vendors—including some providing critical enterprise AI infrastructure—declined to patch the identified vulnerabilities, citing them as "intended functionality" rather than flaws. This stance highlights a greater industry problem: the line between feature and exploit is often blurred in rapidly evolving AI solutions.
Disconnect Between AI Innovation and Security
The split response shows how traditional approaches to security lag behind velocity in AI agent development. Features meant to offer seamless automation may inadvertently open up gaping security holes. Without sector-wide agreement on security baselines or rapid adoption of agent-specific controls, entire industries remain exposed to hazards that transcend those faced with conventional software.Risks and Consequences for the Enterprise
Data Exfiltration and Workflow Manipulation
The risks created by these vulnerabilities are urgent and multifaceted:- Data loss: Sensitive documents, emails, and contracts can be silently siphoned off to attacker-controlled repositories
- Financial threat: Payment records and deal flows in CRM systems can be manipulated or redirected, affecting revenue and exposing organizations to fraud
- Reputation damage: Customers and partners expect confidentiality and process integrity—both can be compromised at-scale in real time
- Persistent compromise: Malicious instructions or memories implanted in AI agents persist across sessions, creating a lasting foothold for attackers
Exploits at Machine Speed
The ability for attackers to automate these attacks takes the timeline for compromise from weeks or days to mere seconds. With AI agents operating 24/7 and responding to every external trigger, a single weaponized email or workflow action can set off a chain reaction across an entire digital ecosystem.Erosion of Trust in AI
Perhaps most troubling is the growing realization that organizations can no longer "set and forget" their reliance on AI automation. When AI agents are hijackable and autonomously malicious, the core promise of digital workflows—speed, consistency, and security—is fundamentally undermined.Defending the New Attack Surface
Shortcomings of Traditional Security Approaches
Standard security controls, such as endpoint protection and network firewalls, offer minimal defense against agent-centric threats. They are not designed to scrutinize:- The context of AI-driven automation flows
- Nuanced interactions triggered by LLMs (large language models)
- Intent-level manipulations occurring in real time
The Push for Agent-Centric Security Platforms
Zenity Labs is championing a category of security explicitly aligned to the risks of AI-driven automation. Their agent-centric security platform promises:- Deep visibility into every AI agent’s access, workflow, and automation context
- Policy enforcement capabilities tailored to AI-powered tools rather than generic software
- Real-time detection of anomalous or malicious agent behavior, including silent exploit chains
- Developer-focused tools to integrate security testing directly into AI agent pipeline
Roadmap for Enterprise Protection
Given the scale and stealth of these vulnerabilities, enterprises should immediately consider the following steps:- Inventory All AI Agents: Identify every instance of AI tool usage across the organization, including shadow IT deployments.
- Restrict AI Agent Privileges: Grant the minimal level of access required for each agent’s primary function—no more.
- Implement Rigorous Input Sanitization: Treat all external inputs (emails, tickets, calendar invites) as potentially hostile, and enforce strict validation prior to automated agent action.
- Monitor Agent Interactions in Real Time: Leverage agent-centric detection tools to flag suspicious conversational flows, privilege escalations, and memory manipulations.
- Engage with Vendor Security Teams: Demand transparency regarding the mechanisms and limitations of deployed enterprise AI agents; participate in responsible disclosure processes and request priority security patches.
Critical Analysis: The Strengths and Shadow Sides of AI Agent Automation
The efficiency and scalability brought to enterprises by AI agents are undeniable. Automated customer support, rapid research, document management, and integration with diverse business systems all save time and reduce human error.Yet this same power, when misdirected, can foster catastrophic risk:
- Strengths: Automating repetitive or structured tasks, 24/7 availability, integration with data sources, and customizability via prompt engineering or workflow tools.
- Risks: Dramatic amplification of the “blast radius” for successful attacks, the introduction of hard-to-detect persistent threats, and the enabling of business logic abuse beyond the reach of legacy controls.
The Road Ahead: From Discovery to Defense
Zenity Labs’ exposé puts the global enterprise sector on notice: the age of fully automated AI agent attacks is both real and actively exploited. As AI becomes more deeply woven into business process, the line between productivity and peril narrows. Vendors’ mixed reactions highlight that comprehensive, agent-aware security policies are not just an option—they are a necessity.Organizations must scale up not only their adoption of AI but also their vigilance and skepticism about how these systems work under the hood. This means treating AI agents as both a competitive asset and a risk vector of the highest order. Success in this new environment will be measured by how quickly the industry can shift from patchwork security to holistic, intent-aware defense for every piece of automated intelligence embedded within the enterprise.
