Dive Brief:<\/p>\n

The vulnerability of the \u201cconnective tissue\u201d of the AI ecosystem \u2014 the Model Context Protocol and other tools that let AI agents communicate \u2014 \u201chas created a vast and often unmonitored attack surface\u201d that is making it easier for hackers to use AI to launch cyberattacks, Cisco said in a report published Thursday.
\nCisco said AI tools\u2019 increasing ability to \u201cexecute processes, access databases, and push code on behalf of humans\u201d has become the dominant AI risk and warned companies not to give AI \u201cunsupervised control over critical business functions.\u201d
\nThe new report also described nation-state hackers\u2019 use of AI and warned businesses about potential AI supply-chain crises.<\/p>\n

Dive Insight:
\nHackers\u2019 abuse of AI tools has garnered significant public attention, but few business leaders understand how the vulnerabilities in the MCP could make that abuse worse.
\nMCP has become the de facto standard for connecting AI models to external data sources since Anthropic introduced it in 2024. But over the past few years, theoretical and real-world attacks have exploited flaws in the protocol. Cisco highlighted examples involving WhatsApp chat exfiltration, remote code execution and unauthorized file access.
\nIn another case highlighted in the report, an attacker published a malicious package designed to look like an MCP integration for the Postmark email platform. \u201cIt blind-carbon-copied (BCC’d) every email sent through the agent to an attacker-controlled address,\u201d Cisco researchers wrote. \u201cBecause AI agents are often trusted with sensitive communications (invoices, password resets, internal memos), malicious tools like this could allow attackers to harvest a treasure trove of sensitive data silently.\u201d
\nGoing forward, Cisco said, \u201corganizations should start to treat MCP servers, agent tool registries, and context brokers with the same hardened approach as they would an API gateway or database.\u201d The company encouraged businesses to establish MCP security best practices, including using APIs that offer AI models the least necessary amount of privileges and closely monitoring AI agents\u2019 activities.
\nThe Postmark package incident highlighted a broader, related AI risk: supply-chain compromises. Similar to the SolarWinds crisis, in which Russian hackers sabotaged a widely used IT management platform, Cisco said \u201ca coordinated, mass supply-chain attack where a widely used AI library or foundation model is compromised at the source\u201d \u2014 such as the theft of a signing key for a platform like Hugging Face that led to the distribution of malicious model updates \u2014 could have \u201ca profound impact\u201d that would \u201cforce industry and government action.\u201d
\nUntil such a crisis precipitates emergency action, Cisco said, \u201cthe relative immaturity in defining security protocols and approaches towards this new agentic ecosystem\u201d will make it difficult for businesses to safely use AI agents to boost productivity.
\nCisco also predicted that as AI companies got better at detection prompt-injection attacks, hackers would \u201cmove deeper into [an AI] model\u2019s memory\u201d and engage in different forms of manipulation. The company cited the example of \u201cvector embedding attacks,\u201d in which hackers tamper with the vector databases where AI models store newly learned information for later use.
\nResearchers also expect nation-state groups\u2019 sophisticated AI abuse techniques to filter down to the cybercrime ecosystem, leading to \u201cthe emergence of automated or custom agentic services on the dark web that can be rented to perform end-to-end hacks.\u201d
\n\u201cThis will democratize advanced cyber capabilities,\u201d Cisco warned, \u201cflooding defenders with machine-speed attacks.\u201d<\/p>\n
