5 Critical cyber threats every startup founder should be aware of

Cybersecurity isn’t just a concern for large corporations; it’s a critical issue for startups and small businesses too. With limited resources and often less robust security measures, startups are increasingly becoming targets for cybercriminals. According to the UK Government’s Cyber Security Breaches Survey 2023, 39% of businesses identified a cyber attack in the past 12 months. Understanding and mitigating these threats is essential to protect your business. Here are five critical cyber threats every startup founder should be aware of.

1. Phishing attacks

Phishing attacks are one of the most common and damaging cyber threats faced by startups. Cybercriminals use deceptive emails, messages, or websites to trick individuals into revealing sensitive information, such as passwords or credit card numbers. According to the Anti-Phishing Working Group (APWG), phishing attacks have increased by 65% in 2022, affecting businesses of all sizes.

The sophistication of phishing attacks has grown significantly. Gone are the days of poorly worded emails; today’s phishing attempts often mimic legitimate communications convincingly. For example, an email might appear to come from a trusted source like a bank or a popular service provider, urging immediate action to avoid a security breach.

To combat phishing, educate your employees about recognising suspicious emails and messages. Implementing email filtering solutions and two-factor authentication (2FA) can add an extra layer of security. Regularly updating your software and systems can also help mitigate the risk by patching vulnerabilities that attackers might exploit.

2. Ransomware

Ransomware is a type of malicious software that encrypts a victim’s files. The attacker then demands a ransom to restore access to the data. This form of cyber attack has become increasingly prevalent, with the FBI reporting a 62% increase in ransomware incidents in 2022.

Startups are particularly vulnerable to ransomware because they may not have comprehensive backup solutions in place. An attack can disrupt operations, lead to significant financial loss, and damage your reputation. For instance, in 2021, the average ransom payment increased to £130,000, according to cybersecurity firm Sophos.

How to protect against ransomware:

• Regular backups: Ensure regular backups of critical data and store them in a separate, secure location. Implementing cloud storage solutions can offer a secure and scalable backup option, ensuring data can be quickly restored without paying a ransom.
• Antivirus and anti-malware software: Invest in robust antivirus and anti-malware software to detect and prevent ransomware attacks.
• Employee training: Educate employees on recognising potential ransomware threats, such as suspicious email attachments or links.
• Network segmentation: Limit the spread of ransomware by segmenting your network, restricting access, and isolating critical data.

3. Insider threats

Insider threats involve employees, contractors, or business partners who intentionally or unintentionally cause harm to the organisation. According to the Ponemon Institute’s 2022 Cost of Insider Threats report, the average cost of an insider threat incident is approximately £9.7 million.

These threats can take various forms, from data theft and sabotage to accidental data breaches due to negligence. For startups, where employees often have access to sensitive information across multiple roles, the risk is particularly high. A disgruntled employee or a careless mistake can lead to substantial damage.

Mitigating insider threats:

• Access controls: Implement strict access controls to ensure that employees only have access to the information necessary for their roles.
• Regular security policies: Regularly update and enforce security policies to promote a culture of security awareness.
• Monitoring tools: Use monitoring tools to detect unusual behaviour that might indicate a potential insider threat.

Fostering a culture of security awareness and implementing appropriate access controls can significantly reduce the risk of insider threats. You can also learn more about how to implement these strategies in our guide on 10 Ways AI can accelerate your startup’s growth.

4. Distributed denial of service (DDoS) attacks

A DDoS attack involves overwhelming a network, service, or website with a flood of internet traffic, causing it to become slow or unavailable. These attacks can be devastating for startups, leading to downtime, lost revenue, and reputational damage. According to Kaspersky, the number of DDoS attacks increased by 50% in 2022.

Startups with an online presence are particularly vulnerable, as a successful DDoS attack can cripple your website or application, driving away customers and eroding trust. For example, a DDoS attack on a popular e-commerce platform could result in significant sales losses during peak shopping periods.

How to defend against DDoS attacks:

• CDNs and DDoS mitigation services: Use a Content Delivery Network (CDN) and DDoS mitigation services that can absorb and filter malicious traffic.
• Infrastructure updates: Regularly update your infrastructure to handle increased traffic loads.
• Incident response plan: Develop an incident response plan to quickly address and mitigate the impact of an attack.

5. Advanced persistent threats (APTs)

APTs are prolonged and targeted cyber attacks where an intruder gains access to a network and remains undetected for an extended period. These attacks are often sophisticated and aim to steal sensitive data rather than cause immediate damage. The UK’s National Cyber Security Centre (NCSC) has highlighted APTs as a significant threat to businesses, including startups.

APTs typically target businesses with valuable intellectual property or sensitive customer data. The attackers use a variety of techniques, including social engineering, malware, and exploiting vulnerabilities to infiltrate and move laterally within the network. Once inside, they can exfiltrate data slowly to avoid detection.

How to protect against APTs:

• Strong network security: Implement strong network security measures, such as intrusion detection systems (IDS) and intrusion prevention systems (IPS).
• Zero-trust security model: Employ a zero-trust security model, where all users and devices must be verified before accessing network resources.
• Continuous monitoring: Use continuous monitoring and threat hunting to detect unusual activity indicative of an APT.
