When AI Becomes the Attack Tool

Artificial intelligence is changing how businesses operate, from automating everyday tasks to analysing data and improving productivity. But the same capabilities that make AI useful to businesses can also make it useful to cybercriminals.

Attackers do not necessarily need to invent entirely new ways to compromise an organisation. AI can help them refine existing techniques, automate repetitive tasks, produce more convincing communications and adapt their approach to different targets.

For businesses, this creates a challenge that goes beyond securing AI platforms themselves. It means understanding how AI could be used against their people, systems, networks and data, while ensuring their existing security measures can keep pace.

AI is changing the economics of cybercrime

Historically, some cyberattacks required considerable time, technical expertise and manual effort. AI can reduce the effort involved in certain activities, potentially allowing attackers to operate at greater speed or scale.

For example, AI tools can help generate phishing messages, summarise publicly available information about a target, translate communications, analyse code and support the development of malicious scripts. The sophistication of the results varies, and AI does not automatically turn an inexperienced criminal into a highly capable attacker. However, it can lower barriers to entry and make established attack methods more efficient.

The implication for businesses is straightforward: security teams cannot rely on the assumption that poorly written emails, obvious mistakes or relatively simple attack techniques will always give criminals away.

Five ways attackers could use AI against your business

1. More convincing phishing and impersonation

Phishing remains an effective route into business systems because it exploits human trust. AI can help attackers create messages that reflect an organisation’s terminology, imitate a colleague’s writing style or refer to genuine business activities.

Voice cloning and AI-generated video can also support impersonation attempts. An employee might receive what appears to be a call from a senior executive requesting an urgent payment or a change to supplier details.

These techniques do not have to be perfect to be effective. They only need to convince someone to act without checking.

What businesses can do: Combine email security and identity protection with clear verification procedures. Payment requests, changes to bank details and unusual requests for sensitive information should be checked through a separate, trusted channel, even when the sender appears familiar.

2. Faster reconnaissance and vulnerability discovery

Before launching an attack, criminals often research their targets. They may look for exposed systems, outdated software, employee information, third-party relationships and publicly accessible technical details.

AI can assist with processing large amounts of information and identifying patterns that may otherwise take longer to uncover. Depending on the tools and access available, it can also help people understand software weaknesses or develop scripts to test systems.

This creates a challenge for organisations with complex environments, ageing infrastructure or limited visibility of their internet-facing assets.

What businesses can do: Maintain an accurate inventory of systems, review externally exposed assets, apply security updates and prioritise vulnerabilities based on exploitability and business impact. Regular vulnerability assessments can help identify weaknesses before they become an entry point.

3. Malware development and adaptation

AI can assist with writing, explaining, modifying and debugging code. In a malicious context, those capabilities may support the creation or adaptation of scripts, malware components and attack tools.

AI can also help attackers understand unfamiliar environments or troubleshoot technical problems. However, generated code can be unreliable, detectable or ineffective, and advanced malware does not simply appear because someone has access to a chatbot.

The wider concern is that AI may make some stages of malware development and deployment more accessible, while established security controls still need to detect malicious behaviour rather than rely solely on recognising known files.

What businesses can do: Use endpoint detection and response (EDR), apply application controls where appropriate, restrict administrative privileges and monitor suspicious behaviour. Effective protection should look for indicators of compromise and unusual activity, not just known malware signatures.

4. Automated attacks against identities and accounts

Compromised credentials remain valuable to attackers because legitimate access can allow them to bypass some traditional perimeter controls.

AI-assisted workflows may help criminals organise stolen information, identify potential targets or support the automation of attack activity. Credential stuffing, password attacks and session theft remain relevant risks, whether or not AI is involved.

Once an account is compromised, an attacker may attempt to access email, cloud applications, remote access services or privileged systems.

What businesses can do: Enforce multi-factor authentication (MFA), prioritise phishing-resistant authentication for high-risk accounts, use least-privilege access and monitor unusual sign-ins. Where a compromise is suspected, revoke active sessions and affected credentials or tokens promptly.

5. Attacks that adapt to the environment

AI is increasingly being explored for more autonomous workflows, including the ability to interpret information, select tools and carry out multi-step tasks. In a malicious setting, these capabilities could support more adaptive reconnaissance, vulnerability exploitation or post-compromise activity.

The extent to which such workflows become reliable and widely used will vary. It is important to distinguish demonstrated capabilities from speculation about fully autonomous attacks. Nevertheless, defenders should prepare for attackers to combine automation with human decision-making to move more quickly.

What businesses can do: Improve visibility across endpoints, networks, identities and cloud environments. Segment critical systems, limit unnecessary privileges and ensure alerts can be investigated promptly. Where an attacker gains access, the objective is to detect suspicious behaviour early and prevent it from spreading.

Shadow AI: the risk already inside the business

AI risk is not limited to external attackers. Employees may use unapproved AI tools to summarise documents, analyse customer information, generate code or speed up administrative work.

Without appropriate controls, sensitive information could be entered into services that have not been assessed for the organisation’s security, privacy or compliance requirements. AI integrations and connected applications may also introduce new permissions, data flows and potential attack paths.

A blanket ban may not be realistic or effective. Employees need clarity about which tools are approved, what information they can use and how to work safely with AI.

Businesses should establish an AI usage policy, assess tools before adoption, control access to sensitive data and review how AI applications connect to internal systems. Security teams should also understand where AI is already being used, including tools introduced by individual departments without formal IT approval.

Why traditional security measures still matter

AI may change how attacks are prepared and delivered, but many of the underlying weaknesses remain familiar: unpatched systems, excessive permissions, weak authentication, exposed services, poor network segmentation and limited monitoring.

This is why businesses should not treat AI security as a separate problem that replaces their existing security strategy. It should be considered alongside identity security, endpoint protection, network defence, vulnerability management and incident response.

A layered approach can help reduce the likelihood of a successful attack and limit the damage if one occurs.

Prevention: Reduce the attack surface through secure configuration, patching, access controls and regular assessments.

Detection: Monitor activity across endpoints, networks, cloud services and identities, looking for suspicious behaviour that may indicate compromise.

Containment: Use segmentation, least-privilege access and clear response procedures to limit an attacker’s ability to move between systems.

Recovery: Maintain tested backups, incident-response plans and clear responsibilities so that essential services can be restored efficiently.

AI governance: Assess approved AI tools, control sensitive data access and review the security implications of AI integrations and automated workflows.

How ANSecurity can help businesses prepare

As AI becomes more widely used by both businesses and attackers, security decisions need to reflect the realities of each organisation’s environment. Buying another security product is not necessarily the answer if existing controls are poorly configured, vulnerabilities remain unresolved or security tools are not providing the visibility the business needs.

ANSecurity brings nearly 25 years of experience in network and cybersecurity, helping organisations assess their security posture, identify weaknesses and implement practical improvements.

Working alongside internal IT teams, we can support businesses with vulnerability management, security assessments, network protection, endpoint and extended detection and response, and broader security strategy. Our vendor-agnostic approach helps ensure recommendations are based on business priorities, existing technology and available resources.

AI will continue to create opportunities for businesses and new possibilities for attackers. The organisations best placed to manage that change will be those that understand their exposure, strengthen their foundations and know how to respond when something goes wrong.
