10 Signs your business is being targeted by hackers

Cyber attacks are on the rise, with UK businesses increasingly becoming targets for hackers. The 2023 UK Cyber Security Breaches Survey revealed that 39% of businesses identified a cyber attack within the past year. Recognising early signs of hacking can make all the difference in protecting your business. Here are the top 10 warning signs that your business may be under attack.

1. Unusual login activity

Unusual login activity, such as repeated failed attempts or logins from unexpected locations, could indicate that hackers are trying to access your systems.

What to do: Monitor login activity and enforce multi-factor authentication (MFA). Regular penetration testing can identify vulnerabilities in your login protocols.

2. Unexpected changes to files

File changes, deletions, or the sudden appearance of unfamiliar files can be a sign of a malware attack or unauthorised access.

What to do: Regularly back up your data and use file integrity monitoring tools. Learn more about safeguarding your data in our blog on essential cybersecurity tools.

3. Ransomware messages

If you see a message demanding payment in exchange for decrypting your data, your business is already under attack by ransomware.

What to do: Disconnect affected systems and contact a professional incident response service immediately.

4. Slower-than-usual systems

Unexplained slowness in your systems could indicate a DDoS attack or malware operating in the background.

What to do: Use intrusion detection systems and consider a vulnerability assessment with DarkShield.

5. Sudden increase in spam emails

An increase in phishing emails targeting your employees could mean hackers are testing your defences.

What to do: Train employees to recognise phishing attempts and implement robust email filtering systems. For detailed strategies, visit our blog on preventing cyber attacks.

6. Strange network activity

Unusual spikes in network traffic, particularly outside business hours, can signal that hackers are attempting to exploit your systems.

What to do: Monitor network activity and use firewalls to block suspicious traffic. Regular penetration testing can identify weak points.

7. Employees locked out of accounts

Account lockouts may occur if hackers are attempting brute-force attacks or have already taken control of accounts.

What to do: Reset passwords immediately and enable MFA to secure access. Explore managed cybersecurity services for ongoing protection.

8. Suspicious outgoing communication

If your systems are sending emails or making requests to unknown domains, it may indicate a malware infection or botnet activity.

What to do: Scan your systems for malware and update your security software. Learn more in our blog on cybersecurity threats.

9. Unauthorised software installations

Hackers often install malicious software to gain control or steal data. Spotting unfamiliar software on your systems can be a red flag.

What to do: Remove unauthorised programs immediately and conduct a full vulnerability assessment with DarkShield.

10. Alerts from security tools

Ignoring alerts from antivirus or intrusion detection systems can leave you vulnerable to attacks already underway.

What to do: Always investigate security alerts promptly and consider a professional incident response service for immediate action.
