Top 5 Cyber Security Threats Targeting Architects in 2025

Architects have greatly benefited from the myriad of digital tools that have emerged in the last few years: cloud-based design tools, remote collaboration platforms, project management software, and more. This sort of technology has made it easier to create accurate, detailed designs faster and more efficiently.

However, the same digital tools have also presented cybercriminals with new avenues to attack. These exact channels provide malicious actors with new ways to gain access to sensitive data, intellectual property, and financial records held by architecture firms.

With 2025 well under way, it’s time to reassess your cyber security posture. Let’s take a look at the top 5 cyber security threats targeting architectural firms – and, more importantly, what you can do to thwart these attacks.

1. Ransomware Attacks

Ransomware attacks remain one of the biggest cyber security risks for architectural firms in 2025. These attacks involve cybercriminals encrypting critical files and demanding payment to restore access. With firms relying more and more on cloud storage and digital collaboration tools, threat actors see an opportunity to disrupt operations and extort money.

Why Architectural Firms Are Targets

Architectural firms handle large design files, sensitive client information, and proprietary blueprints. Losing access to these assets—even temporarily—can halt projects, delay deadlines, and damage reputations.

These firms often work with external vendors, increasing their exposure to supply chain attacks that can introduce ransomware through exploited vulnerabilities in third-party software.

Cybercriminals use a mix of social engineering attacks, phishing attacks, and high-level malware tactics to infiltrate systems. A single compromised email account can be enough for an attacker to gain access to project files, financial data, and internal networks.

How to Reduce the Risk of Ransomware Attacks

Firms must take a proactive approach to threat detection and prevention. Key strategies include:

Regular Backups: Maintain secure, offline backups of critical files to ensure quick recovery after a cyber incident.
Email Security Measures: Implement AI-powered threat detection tools to identify malicious activity in emails and prevent phishing attacks.
Employee Training: Educate staff on recognising social engineering attacks and avoiding suspicious links or attachments.
Access Controls: Limit user permissions, ensuring only authorised employees can modify or delete critical data.
Incident Response Plan: Develop a clear strategy for responding to ransomware attacks, including communication protocols and system recovery steps.

2. Intellectual Property Theft

For architectural firms, intellectual property (IP) is one of the most valuable assets. Detailed blueprints, design concepts, and client project plans hold significant commercial value, making them a prime target for cybercriminals. IP theft is not just a concern for large corporations—small and mid-sized firms are equally at risk as threat actors look for easier targets with fewer security protections.

How Cybercriminals Steal Architectural Designs

Threat actors use a range of tactics to steal confidential information, including:

Phishing Attacks: Fake emails impersonating clients or colleagues trick employees into revealing login credentials.
Insider Threats: Current or former employees intentionally or accidentally leak sensitive files.
Cloud Security Breaches: Poorly configured cloud storage or weak authentication allows unauthorised access.
Supply Chain Attacks: Hackers target third-party vendors with exploited vulnerabilities to infiltrate multiple firms at once.

Stolen IP can be sold to competitors, used for fraudulent projects, or even leaked online, causing significant financial and reputational harm. A high-profile cyberattack targeting an architecture firm could lead to legal disputes, regulatory penalties, and clients departing.

How to Secure Intellectual Property

To mitigate security risks of IP theft, architectural firms should:

Restrict Access: Implement role-based permissions to ensure employees only access data relevant to their work.
Use Strong Authentication: Enforce multi-factor authentication (MFA) for all cloud services and internal systems.
Encrypt Sensitive Data: Protect blueprints and client information with encryption both in transit and at rest.
Monitor for Malicious Activity: Deploy AI-powered threat detection tools to flag unauthorised file access.
Secure Social Media & Email: Limit the sharing of project details online and train employees to recognise social engineering attacks.

3. Business Email Compromise & Phishing Attacks

Email is one of the weakest links in cyber security, and threat actors are exploiting it with increasingly realistic phishing attacks. Business Email Compromise (BEC) scams target architectural firms by impersonating executives, clients, or vendors to trick employees into transferring funds or sharing sensitive information.

How These Attacks Work

Cybercriminals use social engineering attacks to manipulate victims. They might send an email that appears to come from a senior partner requesting an urgent payment or a fake invoice from a trusted supplier. Since architectural firms frequently interact with multiple stakeholders—clients, contractors, and suppliers—detecting fraudulent requests can be challenging.

A high-profile cyberattack involving BEC can have severe financial and reputational consequences. A single compromised account may allow threat actors to gain access to confidential project data, internal communications, and financial records.

Worse still, attackers often use hijacked accounts to launch further malicious activity, expanding the breach across the firm’s network.

How to Reduce the Risk of BEC & Phishing Attacks

Security teams must implement strict email security protocols to prevent cyber risks. Key strategies include:

Multi-Factor Authentication: Adding an extra layer of security makes it harder for hackers to exploit stolen credentials.
AI-Powered Threat Detection: Automated tools can scan e mails for malicious activity, helping prevent attacks before they succeed.
Employee Training: Staff should be able to identify social engineering attacks, suspicious emails, and impersonation attempts.
Strict Payment Verification Processes: Always verify payment requests through a secondary communication method, such as a phone call.
Incident Response Plan: Firms should have a clear protocol for dealing with a cyber incident, including isolating compromised accounts.

4. Cloud Security Vulnerabilities

Architectural firms rely heavily on cloud-based design software, file storage, and collaboration tools. However, without proper security measures, cloud environments can become a major target for threat actors. Misconfigured settings, weak passwords, and unprotected access points create security risks that cybercriminals can exploit.

The Risks of Cloud-Based Systems

Cloud storage and project management platforms provide flexibility, but they also introduce cyber risks if not properly secured. Some of the most common vulnerabilities include:

Weak Access Controls: Without strong authentication, hackers can gain access to sensitive design files and client information.
Exploited Vulnerabilities: Software flaws or unpatched systems can be entry points for attackers.
Supply Chain Attacks: Threat actors may target third-party cloud providers to infiltrate multiple firms at once.
Insider Threats: Employees with unnecessary access to sensitive data pose a risk—either through negligence or malicious activity.

How to Secure Cloud Environments

To strengthen cloud security and prevent data breaches, firms should:

Enforce Role-Based Access Controls (RBAC): Limit access to sensitive data based on job roles.
Use Strong Authentication: Require MFA for all cloud services.
Regularly Audit Security Settings: Ensure cloud configurations follow best practices to avoid exploited vulnerabilities.
Monitor for Malicious Activity: Deploy AI-powered monitoring tools to detect suspicious logins and data transfers.
Have a Cloud Incident Response Plan: Security teams should be prepared to respond quickly to any cyber incident involving cloud infrastructure. A cloud IRP must differ from a regular IRP.

5. Insider Threats

Cyber threats don’t always come from the outside. Malicious activity or accidental data leaks from employees, contractors, or business partners can be just as damaging as an external cyberattack. Whether intentional or unintentional, insider threats can expose sensitive information or compromise IP.

How Insider Threats Occur

Because insider threats originate from within, they can be harder for security teams to detect and prevent. These threats can take several forms:

Disgruntled Employees: Former employees who still have system access may attempt to steal or delete data.
Accidental Leaks: An employee unknowingly shares confidential files through unsecured channels like social media or personal email.
Compromised Credentials: If an employee falls for phishing attacks, hackers can use their credentials to infiltrate company systems.
Third-Party Risks: Contractors and vendors with access to firm data can introduce security risks if their accounts are compromised.

How to Mitigate Insider Threats

To protect against both accidental and intentional insider threats, firms should:

Implement a Zero Trust model: Requires verification of every user or device attempting to access resources.
Implement AI-Powered Threat Detection: Use automated monitoring to identify suspicious behaviour, such as unusual file downloads or logins.
Restrict the Use of Personal Devices and Social Media: Ensure sensitive information is not shared on unsecured platforms.
Revoke Access Immediately for Departing Employees: A well-defined offboarding process prevents former staff from retaining access.
