Mark Cuban Says AI Hack Agents Are Like Cockroaches, but Companies Can Fight Back With AI

Mark Cuban Compares AI Hack Agents to Cockroaches

Billionaire entrepreneur and investor Mark Cuban has compared AI-powered cyberattack agents to cockroaches, warning that their ability to operate at scale could make cybersecurity increasingly challenging.

Speaking at Reuters Total Health in Nashville on October 23, 2026, Cuban said he was not pessimistic about artificial intelligence. Instead, he argued that businesses could use the same technology to strengthen their cybersecurity systems and counter attacks generated by malicious AI agents.

Cuban's comments highlight a growing debate about how artificial intelligence could change the balance between cybercriminals and the organisations attempting to defend against them.

Why Does Cuban Compare AI Agents to Cockroaches?

Cuban used the example of cockroaches entering a newly built house despite efforts to keep them out.

His comparison was intended to explain how large numbers of automated AI agents could repeatedly probe digital systems and potentially find weaknesses. Even if a company blocks one attempted intrusion, other automated agents could continue testing its defences.

According to Cuban, the concern is not necessarily that AI invents entirely new hacking methods. Instead, the technology can allow existing techniques to be deployed at a much greater scale and speed.

He argued that this ability to automate repeated attempts is a major reason organisations need to strengthen their digital defences.

Cuban Says AI Can Also Strengthen Cybersecurity

Despite highlighting the risks, Cuban said he was not an AI doomer.

His central argument was that businesses could use AI to defend their systems in much the same way attackers use it to search for vulnerabilities.

AI-powered security tools can help organisations analyse large volumes of activity, identify suspicious behaviour, detect vulnerabilities and respond to threats more quickly. Automated systems can also help security teams prioritise alerts and investigate patterns that might otherwise be difficult to identify manually.

Cuban's view is that the technology's potential benefits are not limited to attackers. Companies can also deploy automated tools to improve their ability to detect and prevent malicious activity.

What Are AI-Powered Cyberattack Agents?

AI agents are systems that can carry out tasks with varying degrees of autonomy, depending on how they are designed and the permissions they receive.

In cybersecurity, malicious actors could use such systems to automate activities such as searching for exposed services, analysing publicly available information, identifying potential weaknesses or coordinating repeated attack attempts.

The use of AI may reduce the time and effort required to perform certain activities, potentially allowing attackers to target more systems.

However, AI does not make every attack successful, and automated tools still operate within technical and operational constraints. Effective cybersecurity therefore requires a combination of technology, access controls, monitoring, trained personnel and incident-response procedures.

Why AI Could Change the Cybersecurity Landscape

Traditional cyberattacks can require considerable time and expertise. AI tools may help automate parts of the process, allowing attackers to conduct more attempts in less time.

This creates several challenges for organisations:

• Higher attack volume: Automated agents can potentially generate repeated attempts against exposed systems.

• Faster vulnerability discovery: AI tools may help analyse code, configurations and system behaviour to identify weaknesses.

• Continuous probing: Automated systems can operate repeatedly rather than relying entirely on manual intervention.

• Greater pressure on security teams: Organisations may need to process more alerts and distinguish genuine threats from harmless activity.

• More automation on both sides: Defenders may increasingly use AI to detect suspicious behaviour and respond to incidents.

These are potential capabilities rather than guarantees that every AI agent can perform every task. The actual risk depends on the system, its permissions, the attacker's resources and the security measures in place.

Why Companies Need Stronger AI Security Measures

Cuban's comments reinforce the importance of treating cybersecurity as an ongoing process rather than a one-time investment.

Organisations can reduce their exposure by maintaining updated software, restricting access privileges, monitoring network activity and preparing clear incident-response procedures.

They should also test their systems for vulnerabilities and ensure that AI tools used internally cannot access sensitive information or perform high-impact actions without appropriate safeguards.

AI-based defence tools can be useful, but they should not be treated as a complete replacement for established security practices. Human oversight, strong identity controls, reliable backups and regular security testing remain important.

Mark Cuban's Healthcare Business: Cost Plus Drugs

Alongside his comments about AI, Cuban has continued to develop his healthcare business through Cost Plus Drug Company, the online pharmacy he founded in 2022.

The company uses a transparent pricing model based on the cost it pays for a medicine plus a 15% markup. Its broader aim is to make prescription medicines more affordable by showing customers how prices are calculated.

Cost Plus Drugs has also expanded beyond online medicine sales into pharmaceutical manufacturing. In 2025, it began producing sterile injectable medicines commonly used in hospitals at its own manufacturing facility.

Portable Pharmaceutical Manufacturing Facilities

Cuban said Cost Plus Drugs is developing smaller manufacturing facilities that he describes as “pods”.

These portable, tractor-trailer-sized units are intended to manufacture different types of medicines, including generic drugs and treatments for rare diseases. The facilities could potentially operate individually or together, depending on production requirements.

The concept is intended to make pharmaceutical production more flexible and allow medicines to be manufactured closer to where they are needed, particularly during emergencies or disasters.

However, Cuban said the company was still working with the US Food and Drug Administration (FDA) to obtain the necessary approval for the facilities. The regulatory process remains an important step before the proposed model can be fully implemented.

Cuban's Views on Reducing Healthcare Costs

Cuban also discussed possible measures to make healthcare more affordable in the United States.

He argued that patients' out-of-pocket healthcare payments should count towards their insurance deductibles. He also called for greater transparency in taxpayer-funded healthcare contracts, saying such agreements should be publicly available without unnecessary redactions.

Although Cuban has supported Democratic candidates, he said he did not believe Democrats necessarily had better answers than Republicans on healthcare policy.

His comments reflect his broader focus on pharmaceutical pricing, healthcare affordability and transparency in the sector.

What Does Cuban's Warning Mean for Businesses?

Cuban's analogy draws attention to the possibility that AI could increase the scale of cyberattacks by automating activities that previously required more manual effort.

For businesses, the challenge is to prepare for faster and potentially more frequent attacks without assuming that technology alone can eliminate the risk.

Organisations should evaluate how AI tools are used by employees, limit the permissions granted to automated systems and monitor whether those systems are behaving as intended. They should also ensure that security teams can respond quickly when suspicious activity is detected.

The broader lesson is that AI can become a tool for both attackers and defenders. The outcome will depend partly on how effectively organisations implement security measures and respond to emerging threats.

Key Takeaways

• Mark Cuban compared AI-powered hacking agents to cockroaches that repeatedly find ways into protected spaces.

• He said AI can enable attackers to automate large volumes of cyberattack attempts.

• Cuban believes businesses can use AI-powered tools to strengthen their cybersecurity defences.

• He rejected an entirely pessimistic outlook on AI, arguing that defenders can use the technology against malicious actors.

• His comments came during Reuters Total Health in Nashville on October 23, 2026.

• Cuban also discussed Cost Plus Drugs and its plans for portable pharmaceutical manufacturing facilities.

• The proposed manufacturing pods are awaiting the necessary FDA approval.

• Businesses still need access controls, monitoring, security testing and incident-response plans alongside AI-based defences.

Bottom Line

Mark Cuban believes AI-powered cyberattacks could become more difficult to manage as automated agents allow malicious actors to operate at greater scale. His comparison with cockroaches illustrates how repeated attempts can eventually expose weaknesses in a system.

However, Cuban argues that the same technology can strengthen the other side. By using AI to identify threats and respond more quickly, companies may improve their ability to defend against automated attacks. The key will be combining AI-powered security with strong access controls, continuous monitoring and effective human oversight.
