Are you looking for a way to ensure your business remains prepared for cyber-attacks? For small and medium-sized businesses (SMBs), it seems like this is too good to be true, with the rapid increase in cyber threats.
But with the right IT support in place, your business can remain proactive, minimise downtime, and secure your future.
By learning from past incidents, SMBs can strengthen their defences and prevent history from repeating itself. Let’s explore five key lessons from real-world cyber-attacks and how your business can stay protected.
Case Study: A Major NHS Data Breach in 2024
At the beginning of June 2024, patient data managed by a pathology testing organisation, Synnovis, was stolen in a ransomware attack by the cybercriminal group Qilin. According to a BBC news report, almost 400GB of private information was shared on the criminal group’s darknet site.
The attack resulted in significant service disruptions and a risk to patient data security, including more than 3,000 hospital and GP appointments being disrupted as an immediate result. Let’s look further into the tactics and implications of the attack:
Tactics Used by Attackers
Cybercriminals employed several common tactics to execute this attack:
- Stolen Credentials: Hackers accessed the network using compromised employee login details.
- Lack of Multi-Factor Authentication (MFA): Without additional security layers, stolen passwords were enough to gain access.
- Lateral Movement: Once inside, attackers moved across systems to spread ransomware and encrypt critical data.
- Delayed Detection: The breach was not immediately identified, giving hackers more time to cause damage.
The Impact of the Attack
The consequences of the Synnovis attack were severe:
- The hackers infiltrated the computer systems of the company that is used by two NHS trusts in London and encrypted vital information that rendered IT systems useless.
- NHS England reported that in the months after the attack, over 10,000 outpatient and 1,700 procedures had been postponed.
Key Takeaways for SMBs: Strengthening Cyber Defences
Extending beyond the catastrophic impacts, it’s important for SMBs to understand what they can take away from the lessons learnt in this example, regardless of their industry.
Cybercriminals will target any business with weak security measures, searching for vulnerabilities that provide them access to critical systems, steal data, and cause exponential financial damage.
Minimising this risk, SMBs must adopt a proactive approach to cyber security. Let’s walk through some of the most crucial security measures every business should implement:
1. Enforce Multi-Factor Authentication (MFA) on All Accounts
An effective security measure, multi-factor authentication (MFA) prevents cybercriminals from gaining access through compromised login credentials. MFA ensures security by:
- Requiring an extra verification step (such as a mobile app code or biometric scan), making it harder for hackers to use stolen passwords.
- Preventing unauthorised access, even if credentials are compromised.
- Reducing the risk of email account takeovers, remote access breaches, and financial fraud.
2. Keep Systems, Software, and Devices Updated
Failing to install security updates leaves your business exposed to threats that could have been prevented. Regular patching helps by:
- Closing security loopholes that hackers exploit.
- Strengthening system integrity against new and emerging threats.
- Reducing the risk of malware infections and ransomware attacks.
3. Monitor Systems for Unusual Activity and Potential Threats
Cyber-attacks can go undetected for weeks or even months, enabling hackers to steal data, install backdoors, and prepare large-scale disruptions.
Without real-time monitoring, businesses may not realise they have been breached until the damage is already done. With real-time monitoring, you can:
- Detect suspicious activity such as unauthorised logins, unusual file access, and data exfiltration attempts.
- Help IT teams respond to threats quickly, preventing further escalation.
- Gain insight into ongoing cyber threats and attack patterns.
4. Provide Regular Training for Staff
Employees – while the first line of defence – are also a weak link for businesses. Phishing emails remain one of the most effective ways for cybercriminals to trick employees into revealing credentials, downloading malware, or transferring funds. Provide training to:
- Educate employees on recognising phishing emails, social engineering tactics, and suspicious links.
- Reduce the risk of human error leading to security breaches.
- Encourage a culture of cyber security awareness throughout the organisation.
5. Implement a Strong Backup and Disaster Recovery Plan
With a reliable backup strategy, your business retains its critical data in the event of a cyber-attack and your operations can be restored quickly without paying a ransom. Backups and disaster recovery help by:
- Enabling businesses to recover lost or encrypted files in case of a ransomware attack.
- Ensuring business continuity, reducing downtime, and reducing financial losses.
- Protecting against human errors, hardware failures, and cyber incidents.
