Experts have discovered a new prompt injection attack that can turn ChatGPT into a hacker’s best friend in data thefts. Known as AgentFlayer, the exploit uses a single document to hide “secret” prompt instructions that target OpenAI’s chatbot. An attacker can share what appears to be a harmless document with victims through Google Drive, without any clicks.
AgentFlayer is a “zero-click” threat as it abuses a vulnerability in Connectors, for instance, a ChatGPT feature that connects the assistant to other applications, websites, and services. OpenAI suggests that Connectors supports a few of the world’s most widely used platforms. This includes cloud storage platforms such as Microsoft OneDrive and Google Drive.
Experts used Google Drive to expose the threats possible from chatbots and hidden prompts.
The malicious document has a 300-word hidden malicious prompt. The text is size one, formatted in white to hide it from human readers but visible to the chatbot.
The prompt used to showcase AgentFlayer’s attacks prompts ChatGPT to find the victim’s Google Drive for API keys, link them to a tailored URL, and an external server. When the malicious document is shared, the attack is launched. The threat actor gets the hidden API keys when the target uses ChatGPT (the Connectors feature has to be enabled).
AgentFlayer is not a bug that only affects the Google Cloud. “As with any indirect prompt injection attack, we need a way into the LLM's context. And luckily for us, people upload untrusted documents into their ChatGPT all the time. This is usually done to summarize files or data, or leverage the LLM to ask specific questions about the document’s content instead of parsing through the entire thing by themselves,” said expert Tamir Ishay Sharbat from Zenity Labs.
“OpenAI is already aware of the vulnerability and has mitigations in place. But unfortunately, these mitigations aren’t enough. Even safe-looking URLs can be used for malicious purposes. If a URL is considered safe, you can be sure an attacker will find a creative way to take advantage of it,” Zenith Labs said in the report.
Flashpoint’s Global Threat Intelligence Index report is based on more than 3.6 petabytes of data studied by the experts. Hackers stole credentials from 5.8 million compromised devices, according to the report. The significant rise is problematic as stolen credentials can give hackers access to organizational data, even when the accounts are protected by multi-factor authentication (MFA).
The report also includes details that concern security teams.
Until June 2025, the firm has found over 20,000 exposed bugs, 12,200 of which haven’t been reported in the National Vulnerability Database (NVD). This means that security teams are not informed. 7000 of these have public exploits available, exposing organizations to severe threats.
According to experts, “The digital attack surface continues to expand, and the volume of disclosed vulnerabilities is growing at a record pace – up by a staggering 246% since February 2025.” “This explosion, coupled with a 179% increase in publicly available exploit code, intensifies the pressure on security teams. It’s no longer feasible to triage and remediate every vulnerability.”
Both these trends can cause ransomware attacks, as early access mostly comes through vulnerability exploitation or credential hacking. Total reports of breaches have increased by 179% since 2024, manufacturing (22%), technology (18%), and retail (13%) have been hit the most. The report has also disclosed 3104 data breaches in the first half of this year, linked to 9.5 billion hacked records.
Flashpoint reports that “Over the past four months, data breaches surged by 235%, with unauthorized access accounting for nearly 78% of all reported incidents. Data breaches are both the genesis and culmination of threat actor campaigns, serving as a source of continuous fuel for cybercrime activity.”
In June, the Identity Theft Resource Center (ITRC) warned that 2025 could become a record year for data cyberattacks in the US.
The security bug is now listed as CVE-2025-54135 and can be exploited by giving the AI agent a malicious prompt to activate threat actor control commands.
The Cursor combined development environment (IDE) relies on AI agents to allow developers to code quicker and more effectively, helping them to connect with external systems and resources using Model Context Protocol (MCP).
According to the experts, a threat actor effectively abusing the CurXecute bug could trigger ransomware and ransomware data theft attacks.
CurXecute shares similarities to the EchoLeak bug in Microsoft 365 CoPilot that hackers can use to extort sensitive data without interacting with the users.
After finding and studying EchoLeak, the experts from the cybersecurity company Aim Security found that hackers can even exploit the local AI agent.
Cursor IDE supports the MCP open-standard framework, which increases an agent’s features by connecting it to external data tools and sources.
But the experts have warned that doing so can exploit the agent, as it is open to external, suspicious data that can impact its control flow. The threat actor can take advantage by hacking the agent’s session and features to work as a user.
According to the experts, Cursor doesn’t need permission to run new entries to the ~/.cursor/mcp.json file. When the target opens the new conversation and tells the agent to summarize the messages, the shell payload deploys on the device without user authorization.
“Cursor allows writing in-workspace files with no user approval. If the file is a dotfile, editing it requires approval, but creating one if it doesn't exist doesn't. Hence, if sensitive MCP files, such as the .cursor/mcp.json file, don't already exist in the workspace, an attacker can chain an indirect prompt injection vulnerability to hijack the context to write to the settings file and trigger RCE on the victim without user approval,” Cursor said in a report.
Google Gemini for Workspace can be exploited to generate email summaries that appear legitimate but include malicious instructions or warnings that direct users to phishing sites without using attachments or direct links.
Google Gemini for Workplace can be compromised to create email summaries that look real but contain harmful instructions or warnings that redirect users to phishing websites without using direct links or attachments.
Similar attacks were reported in 2024 and afterwards; safeguards were pushed to stop misleading responses. However, the tactic remains a problem for security experts.
A prompt-injection attack on the Gemini model was revealed via cybersecurity researcher Marco Figueoa, at 0din, Mozilla’s bug bounty program for GenAI tools. The tactic creates an email with a hidden directive for Gemini. The threat actor can hide malicious commands in the message body text at the end via CSS and HTML, which changes the font size to zero and color to white.
According to Marco, who is GenAI Bug Bounty Programs Manager at Mozilla, “Because the injected text is rendered in white-on-white (or otherwise hidden), the victim never sees the instruction in the original message, only the fabricated 'security alert' in the AI-generated summary. Similar indirect prompt attacks on Gemini were first reported in 2024, and Google has already published mitigations, but the technique remains viable today.”
Gmail does not render the malicious instruction as there are no attachments or links present, and the message may reach the victim’s inbox. If the receiver opens the email and asks Gemini to make a summary of the received mail, the AI tool will parse the invisible directive and create the summary. Figueroa provides an example of Gemini following hidden prompts, accompanied by a security warning that the victim’s Gmail password and phone number may be compromised.
Supply-chain threats: CRM systems, automated ticketing emails, and newsletters can become injection vectors, changing one exploited SaaS account into hundreds of thousands of phishing beacons.
Cross-product surface: The same tactics applies to Gemini in Slides, Drive search, Docs and any workplace where the model is getting third-party content.
According to Marco, “Security teams must treat AI assistants as part of the attack surface and instrument them, sandbox them, and never assume their output is benign.”
The new artificial intelligence capability introduced by WhatsApp aims to transform the way users interact with their conversations through sophisticated artificial intelligence. It uses advanced technology from Meta AI to provide a concise summary of unread messages across individual chats as well as group chats, which is referred to as Message Summaries.
The tool was created to help users stay informed in increasingly active chat environments by automatically compiling key points and contextual highlights, allowing them to catch up in just a few clicks without having to scroll through lengthy message histories to catch up. The company claims all summaries are generated privately, so that confidentiality can be maintained and the process of use is as simple as possible for the user.
WhatsApp announces its intention of integrating artificial intelligence-driven solutions into its app to improve user convenience as well as reshape communication habits for its global community with this rollout, sparking both excitement and controversy as a result. Despite being announced last month, WhatsApp’s innovative Message Summaries feature has moved from pilot testing to a full-scale rollout after successfully passing pilot testing.
Having refined the tool and collected feedback from its users, it is now considered to be stable and has been formally launched for wider use. In the initial phase, the feature is only available to US users and is restricted to the English language at this time. This indicates that WhatsApp is cautious when it comes to deploying large-scale artificial intelligence.
Nevertheless, the platform announced plans to extend its availability to more regions at some point in the future, along with the addition of multilingual support. The phased rollout strategy emphasises that the company is focused on ensuring that the technology is reliable and user-friendly before it is extended to the vast global market.
It is WhatsApp's intention to focus on a controlled release so as to gather more insights about users' interaction with the AI-generated conversation summaries, as well as to fine-tune the experience before expanding internationally. As a result of WhatsApp's inability to provide an option for enabling or concealing the Message Summaries feature, there has been a significant amount of discontent among users.
Despite the fact that Meta has refused to clarify the reason regarding the lack of an opt-out mechanism or why users were not offered the opportunity to opt out of the AI integration, they have not provided any explanation so far. As concerning as the technology itself is, the lack of transparency has been regarded equally as a cause for concern by many, raising questions about the control people have over their personal communications. As a result of these limitations, some people have attempted to circumvent the chatbot by switching to a WhatsApp Business account as a response.
In addition, several users have commented that this strategy removed the AI functionality from Meta AI, but others have noted that the characteristic blue circle, which indicates Meta AI's presence, still appeared, which exacerbated the dissatisfaction and uncertainty.
The Meta team hasn’t confirmed whether the business-oriented version of WhatsApp will continue to be exempt from AI integration for years to come. This rollout also represents Meta’s broader goal of integrating generative AI into all its platforms, which include Facebook and Instagram, into its ecosystem.
Towards the end of 2024, Meta AI was introduced for the first time in Facebook Messenger in the United Kingdom, followed by a gradual extension into WhatsApp as part of a unified vision to revolutionise digital interactions. However, many users have expressed their frustration with this feature because it often feels intrusive and ultimately is useless, despite these ambitions.
The chatbot appears to activate frequently when individuals are simply searching for past conversations or locating contacts, which results in obstructions rather than streamlining the experience. According to the initial feedback received, AI-generated responses are frequently perceived as superficial, repetitive, or even irrelevant to the conversation's context, as well as generating a wide range of perceptions of their value.
A Meta AI platform has been integrated directly into WhatsApp, unlike standalone platforms such as ChatGPT and Google Gemini, which are separately accessible by users. WhatsApp is a communication application that is used on a daily basis to communicate both personally and professionally. Because the feature was integrated without explicit consent and there were doubts about its usefulness, many users are beginning to wonder whether such pervasive AI assistance is really necessary or desirable.
It has also been noted that there is a growing chorus of criticism about the inherent limitations of artificial intelligence in terms of reliably interpreting human communication. Many users have expressed their scepticism about AI's ability to accurately condense even one message within an active group chat, let alone synthesise hundreds of exchanges. It is not the first time Apple has faced similar challenges; Apple has faced similar challenges in the past when it had to pull an AI-powered feature that produced unintended and sometimes inaccurate summaries.
As of today, the problem of "hallucinations," which occur in the form of factually incorrect or contextually irrelevant content generated by artificial intelligence, remains a persistent problem across nearly every generative platform, including commonly used platforms like ChatGPT. Aside from that, artificial intelligence continues to struggle with subtleties such as humour, sarcasm, and cultural nuance-aspects of natural conversation that are central to establishing a connection.
In situations where the AI is not trained to recognise offhand or joking remarks, it can easily misinterpret those remarks. This leads to summaries that are alarmist, distorted, or completely inaccurate, as compared to human recipients' own. Due to the increased risk of misrepresentation, users who rely on WhatsApp for authentic, nuanced communication with colleagues, friends, and family are becoming more apprehensive than before.
A philosophical objection has been raised beyond technical limitations, stating that the act of participating in a conversation is diminished by substituting real engagement for machine-generated recaps. There is a shared sentiment that the purpose of group chats lies precisely in the experience of reading and responding to the genuine voices of others while scrolling through a backlog of messages.
However, there is a consensus that it is exhausting to scroll through such a large backlog of messages. It is believed that the introduction of Message Summaries not only threatens clear communication but also undermines the sense of personal connection that draws people into these digital communities in the first place, which is why these critics are concerned.
In order to ensure user privacy, WhatsApp has created the Message Summaries feature using a new framework known as Private Processing, which is designed to safeguard user privacy. Meta and WhatsApp are specifically ensuring that neither the contents of their conversations nor the summaries that the AI system produces are able to be accessed by them, which is why this approach was developed.
Instead of sending summaries to external servers, the platform is able to generate them locally on the users' devices, reinforcing its commitment to privacy. Each summary, presented in a clear bullet point format, is clearly labelled as "visible only to you," emphasising WhatsApp's privacy-centric design philosophy behind the feature as well.
Message Summaries have shown to be especially useful in group chats in which the amount of unread messages is often overwhelming, as a result of the large volume of unread messages. With this tool, users are able to remain informed without having to read every single message, because lengthy exchanges are distilled into concise snapshots that enable them to stay updated without having to scroll through each and every individual message.
The feature is disabled by default and needs to be activated manually, which addresses privacy concerns. Upon activating the feature, eligible chats display a discreet icon, signalling the availability of a summary without announcing it to other participants. Meta’s confidential computing infrastructure is at the core of its system, and in principle, it is comparable to Apple’s private cloud computing architecture.
A Trusted Execution Environment (TEE) provides a foundation for Private Processing, ensuring that confidential information is handled in an effective manner, with robust measures against tampering, and clear mechanisms for ensuring transparency are in place.
A system's architecture is designed to shut down automatically or to generate verifiable evidence of the intrusion whenever any attempt is made to compromise the security assurances of the system. As well as supporting independent third-party audits, Meta has intentionally designed the framework in such a way that it will remain stateless, forward secure, and immune to targeted attacks so that Meta's claims about data protection can be verified.
Furthermore, advanced chat privacy settings are included as a complement to these technical safeguards, as they allow users to select the conversations that will be eligible for AI-generated summaries and thus offer granular control over the use of the feature. Moreover, when a user decides to enable summaries in a chat, no notification is sent to other participants, allowing for greater discretion on the part of other participants.
There is currently a phase in which Message Summaries are being gradually introduced to users in the United States. They can only be read in English at the moment. There has been confirmation by Meta that the feature will be expanded to additional regions and supported in additional languages shortly, as part of their broader effort to integrate artificial intelligence into all aspects of their service offerings.
As WhatsApp intensifies its efforts to embed AI capabilities deeper and deeper into everyday communication, Message Summaries marks a pivotal moment in the evolution of relationships between technology and human interaction as the company accelerates its ambition to involve AI capabilities across the entire enterprise.
Even though the company has repeatedly reiterated that it is committed to privacy, transparency, and user autonomy, the response to this feature has been polarised, which highlights the challenges associated with incorporating artificial intelligence in spaces where trust, nuance, and human connection are paramount.
It is a timely reminder that, for both individuals and organisations, the growth of convenience-driven automation impacts the genuine social fabric that is a hallmark of digital communities and requires a careful assessment.
As platforms evolve, stakeholders would do well to remain vigilant with the changes to platform policies, evaluate whether such tools align with the communication values they hold dear, and consider offering structured feedback in order for these technologies to mature with maturity. As artificial intelligence continues to redefine the contours of messaging, users will need to be open to innovation while also expressing critical thought about the long-term implications on privacy, comprehension, and even the very nature of meaningful dialogue as AI use continues to grow in popularity.
The ChatGPT solution has become a transformative artificial intelligence solution widely adopted by individuals and businesses alike seeking to improve their operations. Developed by OpenAI, this sophisticated artificial intelligence platform has been proven to be very effective in assisting users with drafting compelling emails, developing creative content, or conducting complex data analysis by streamlining a wide range of workflows.
OpenAI is continuously enhancing ChatGPT's capabilities through new integrations and advanced features that make it easier to integrate into the daily workflows of an organisation; however, an understanding of the platform's pricing models is vital for any organisation that aims to use it efficiently on a day-to-day basis. A business or an entrepreneur in the United Kingdom that is considering ChatGPT's subscription options may find that managing international payments can be an additional challenge, especially when the exchange rate fluctuates or conversion fees are hidden.
In this context, the Wise Business multi-currency credit card offers a practical solution for maintaining financial control as well as maintaining cost transparency. This payment tool, which provides companies with the ability to hold and spend in more than 40 currencies, enables them to settle subscription payments without incurring excessive currency conversion charges, which makes it easier for them to manage budgets as well as adopt cutting-edge technology.
A suite of premium features has been recently introduced by OpenAI that aims to enhance the ChatGPT experience for subscribers by enhancing its premium features. There is now an option available to paid users to use advanced reasoning models that include O1 and O3, which allow users to make more sophisticated analytical and problem-solving decisions.
The subscription comes with more than just enhanced reasoning; it also includes an upgraded voice mode that makes conversational interactions more natural, as well as improved memory capabilities that allow the AI to retain context over the course of a long period of time. It has also been enhanced with the addition of a powerful coding assistant designed to help developers automate workflows and speed up the software development process.
To expand the creative possibilities even further, OpenAI has adjusted token limits, which allow for greater amounts of input and output text and allow users to generate more images without interruption. In addition to expedited image generation via a priority queue, subscribers have the option of achieving faster turnaround times during high-demand periods.
In addition to maintaining full access to the latest models, paid accounts are also provided with consistent performance, as they are not forced to switch to less advanced models when server capacity gets strained-a limitation that free users may still have to deal with. While OpenAI has put in a lot of effort into enriching the paid version of the platform, the free users have not been left out. GPT-4o has effectively replaced the older GPT-4 model, allowing complimentary accounts to take advantage of more capable technology without having to fall back to a fallback downgrade.
In addition to basic imaging tools, free users will also receive the same priority in generation queues as paid users, although they will also have access to basic imaging tools. With its dedication to making AI broadly accessible, OpenAI has made additional features such as ChatGPT Search, integrated shopping assistance, and limited memory available free of charge, reflecting its commitment to making AI accessible to the public.
ChatGPT's free version continues to be a compelling option for people who utilise the software only sporadically-perhaps to write occasional emails, research occasionally, and create simple images. In addition, individuals or organisations who frequently run into usage limits, such as waiting for long periods of time for token resettings, may find that upgrading to a paid plan is an extremely beneficial decision, as it unlocks uninterrupted access as well as advanced capabilities.
In order to transform ChatGPT into a more versatile and deeply integrated virtual assistant, OpenAI has introduced a new feature, called Connectors, which is designed to transform the platform into an even more seamless virtual assistant. It has been enabled by this new feature for ChatGPT to seamlessly interface with a variety of external applications and data sources, allowing the AI to retrieve and synthesise information from external sources in real time while responding to user queries.
With the introduction of Connectors, the company is moving forward towards providing a more personal and contextually relevant experience for our users. In the case of an upcoming family vacation, for example, ChatGPT can be instructed by users to scan their Gmail accounts in order to compile all correspondence regarding the trip. This allows users to streamline travel plans rather than having to go through emails manually.
With its level of integration, Gemini is similar to its rivals, which enjoy advantages from Google's ownership of a variety of popular services such as Gmail and Calendar. As a result of Connectors, individuals and businesses will be able to redefine how they engage with AI tools in a new way. OpenAI intends to create a comprehensive digital assistant by giving ChatGPT secure access to personal or organisational data that is residing across multiple services, by creating an integrated digital assistant that anticipates needs, surfaces critical insights, streamlines decision-making processes, and provides insights.
There is an increased demand for highly customised and intelligent assistance, which is why other AI developers are likely to pursue similar integrations to remain competitive. The strategy behind Connectors is ultimately to position ChatGPT as a central hub for productivity — an artificial intelligence that is capable of understanding, organising, and acting upon every aspect of a user’s digital life.
In spite of the convenience and efficiency associated with this approach, it also illustrates the need to ensure that personal information remains protected while providing robust data security and transparency in order for users to take advantage of these powerful integrations as they become mainstream. In its official X (formerly Twitter) account, OpenAI has recently announced the availability of Connectors that can integrate with Google Drive, Dropbox, SharePoint, and Box as part of ChatGPT outside of the Deep Research environment.
As part of this expansion, users will be able to link their cloud storage accounts directly to ChatGPT, enabling the AI to retrieve and process their personal and professional data, enabling it to create responses on their own. As stated by OpenAI in their announcement, this functionality is "perfect for adding your own context to your ChatGPT during your daily work," highlighting the company's ambition of making ChatGPT more intelligent and contextually aware.
It is important to note, however, that access to these newly released Connectors is confined to specific subscriptions and geographical restrictions. A ChatGPT Pro subscription, which costs $200 per month, is exclusive to ChatGPT Pro subscribers only and is currently available worldwide, except for the European Economic Area (EEA), Switzerland and the United Kingdom. Consequently, users whose plans are lower-tier, such as ChatGPT Plus subscribers paying $20 per month, or who live in Europe, cannot use these integrations at this time.
Typically, the staggered rollout of new technologies is a reflection of broader challenges associated with regulatory compliance within the EU, where stricter data protection regulations as well as artificial intelligence governance frameworks often delay their availability. Deep Research remains relatively limited in terms of the Connectors available outside the company. However, Deep Research provides the same extensive integration support as Deep Research does.
In the ChatGPT Plus and Pro packages, users leveraging Deep Research capabilities can access a much broader array of integrations — for example, Outlook, Teams, Gmail, Google Drive, and Linear — but there are some restrictions on regions as well. Additionally, organisations with Team plans, Enterprise plans, or Educational plans have access to additional Deep Research features, including SharePoint, Dropbox, and Box, which are available to them as part of their Deep Research features.
Additionally, OpenAI is now offering the Model Context Protocol (MCP), a framework which allows workspace administrators to create customised Connectors based on their needs. By integrating ChatGPT with proprietary data systems, organizations can create secure, tailored integrations, enabling highly specialized use cases for internal workflows and knowledge management that are highly specialized.
With the increasing adoption of artificial intelligence solutions by companies, it is anticipated that the catalogue of Connectors will rapidly expand, offering users the option of incorporating external data sources into their conversations. The dynamic nature of this market underscores that technology giants like Google have the advantage over their competitors, as their AI assistants, such as Gemini, can be seamlessly integrated throughout all of their services, including the search engine.
The OpenAI strategy, on the other hand, relies heavily on building a network of third-party integrations to create a similar assistant experience for its users. It is now generally possible to access the new Connectors in the ChatGPT interface, although users will have to refresh their browsers or update the app in order to activate the new features.
As AI-powered productivity tools continue to become more widely adopted, the continued growth and refinement of these integrations will likely play a central role in defining the future of AI-powered productivity tools. A strategic approach is recommended for organisations and professionals evaluating ChatGPT as generative AI capabilities continue to mature, as it will help them weigh the advantages and drawbacks of deeper integration against operational needs, budget limitations, and regulatory considerations that will likely affect their decisions.
As a result of the introduction of Connectors and the advanced subscription tiers, people are clearly on a trajectory toward more personalised and dynamic AI assistance, which is able to ingest and contextualise diverse data sources. As a result of this evolution, it is also becoming increasingly important to establish strong frameworks for data governance, to establish clear controls for access to the data, and to ensure adherence to privacy regulations.
If companies intend to stay competitive in an increasingly automated landscape by investing early in these capabilities, they can be in a better position to utilise the potential of AI and set clear policies that balance innovation with accountability by leveraging the efficiencies of AI in the process. In the future, the organisations that are actively developing internal expertise, testing carefully selected integrations, and cultivating a culture of responsible AI usage will be the most prepared to fully realise the potential of artificial intelligence and to maintain a competitive edge for years to come.
The CISA, NSA, and FBI teamed with cybersecurity agencies from the UK, Australia, and New Zealand to make a best-practices policy for safe AI development. The principles laid down in this document offer a strong foundation for protecting AI data and securing the reliability and accuracy of AI-driven outcomes.
The advisory comes at a crucial point, as many businesses rush to integrate AI into their workplace, but this can be a risky situation also. Governments in the West have become cautious as they believe that China, Russia, and other actors will find means to abuse AI vulnerabilities in unexpected ways.
The risks are increasing swiftly as critical infrastructure operators develop AI into operational tech that controls important parts of daily life, from scheduling meetings to paying bills to doing your taxes.
From foundational elements of AI to data consulting, the document outlines ways to protect your data at different stages of the AI life cycle such as planning, data collection, model development, installment and operations.
It requests people to use digital signature that verify modifications, secure infrastructure that prevents suspicious access and ongoing risk assessments that can track emerging threats.
The document addresses ways to prevent data quality issues, whether intentional or accidental, from compromising the reliability and safety of AI models.
Cryptographic hashes make sure that taw data is not changed once it is incorporated into a model, according to the document, and frequent curation can cancel out problems with data sets available on the web. The document also advises the use of anomaly detection algorithms that can eliminate “malicious or suspicious data points before training."
The joint guidance also highlights issues such as incorrect information, duplicate records and “data drift”, statistics bias, a natural limitation in the characteristics of the input data.
